Injection molding is a mature, highly precise manufacturing method primarily for plastics (and sometimes elastomers). Because many industries demand consistent quality, interchangeability of parts, and safety assurance, ISO (International Organization for Standardization) standards play a key role in defining norms for processes, testing, safety, quality, and terminology. However, there is no single ISO standard that covers everything about injection molding. Rather, a network of ISO standards applies to various aspects—test specimens, machinery safety, testing protocols, tolerancing, quality systems, domain-specific standards, etc. This article surveys the major ISO standards relevant to injection molding: what they cover, how they are used in practice, and what considerations manufacturers and designers should be aware of.

Brief Overview: What Is ISO? ISO (International Organization for Standardization) is a global, non-governmental body that develops and publishes international standards across many domains—mechanical engineering, materials, quality systems, safety, information technology, environment, etc. ISO standards are voluntary (unless adopted by regulatory bodies), but in many industries and supply chains they become de facto or mandated by contracts, regulations, or customer requirements. Meeting relevant ISO standards can help companies ensure consistency, quality assurance, compliance, and global acceptance. In the context of injection molding, ISO standards typically address: • Safety requirements of machinery • Test specimen molding and material testing • Terminology, symbols, dimensions • Quality management systems (e.g. ISO 9001, ISO 13485) • Tolerancing and geometric dimensioning control • Domain-specific standards (e.g. medical, automotive) Let’s examine the key standards.

Key ISO Standards in Injection Molding ISO 20430:2020 – Plastics & Rubber Machines: Injection Molding Machine Safety Requirements One of the most directly relevant ISO standards to injection molding machinery is ISO 20430:2020, titled “Plastics and rubber machines — Injection moulding machines — Safety requirements”. Scope and Purpose • This standard specifies the essential safety requirements for the design and construction of injection molding machines (hydraulic and/or electrical drive) used in processing plastics and/or rubber. • It addresses hazards, hazardous situations, and events relevant when machines are used as intended or under reasonably foreseeable misuse. • It also interfaces with ISO 12100 (general machine safety principles). • Exclusions: It does not cover mold design or exhaust systems, nor machines built prior to that standard’s publication date. Why It Matters • For machine builders and molders, compliance with ISO 20430 ensures safety in operation, helps meet regulatory safety obligations, and reduces liability risk. • National or regional safety regulations often reference standards like ISO 20430 (or harmonize with them). • It mandates guards, interlocks, pressure relief, emergency stops, safe access provisions, and protective devices. When designing or selecting injection molding equipment, manufacturers must be aware of ISO 20430’s clauses and ensure that all safety elements align with it.

ISO 294 Series – Molding of Test Specimens A family of ISO standards addresses the molding of standard test specimens for plastics under controlled conditions so that comparative material property testing can be reliable. Among these: • ISO 294-1:2017 — Plastics — Injection moulding of test specimens of thermoplastic materials – Part 1: General principles, and molding of multipurpose and bar test specimens. • ISO 294-5:2017 — Plastics — Injection moulding of test specimens of thermoplastic materials – Part 5: Preparation of standard specimens for investigating anisotropy. ISO 294-1:2017 — Key Points and Use • Defines general principles and molding conditions for test specimens (types A1, B1) used in standardized tests (e.g. tensile, flexural). • Ensures that specimen molding is reproducible and that results from different labs or studies are comparable. • It clarifies how to report the molding parameters (temperatures, pressures, times) in a standard format to make data transparent and consistent. • Also ensures that the molds used for specimens can fit in existing molding machines, and that the mold plates are interchangeable. ISO 294-5:2017 — Key Points • Focuses on anisotropy (directional dependence of properties) in molded thermoplastics, often due to molecular orientation or filler alignment. • Specifies a “Type F” mold (80 × 120 mm nominal) for making plate specimens to study anisotropy in tensile properties. • These specimens may not aim for production parts, but are critical for material characterization in research, validation, and material datasheets.

Why This Matters in Practice • When material suppliers publish properties (tensile, modulus, impact) or when designers perform simulation (e.g. mold flow), the test data must originate from a reproducible and comparable standard molding process. ISO 294 series ensures that. • Consistency in test specimen molding conditions helps reduce “scatter” in material property data, improving the reliability of calculations, simulations, and design decisions. Thus, for organizations doing polymer materials testing, polymer selection, or molding validation, these ISO standards are essential.

ISO 12165 / ISO 12180 etc. – Terms, Vocabulary, Components In the domain of mold tooling and manufacturing, there are ISO standards covering terms, symbols, and basic tooling components relevant to injection molding. • ISO 12165 — Tools for moulding — Components of compression and injection moulds and diecasting dies — Terms and symbols. This standard helps unify nomenclature for mold parts (cavities, cores, ejector pins, runners, etc.). • ISO 12180 — Geometrical product specifications (GPS) — Cylindricity / tolerance operators for cylindrical form, which can apply to features in molds or molded parts requiring cylindrical tolerances. (Part of broader GPS family) While these are not “injection molding” specific, they ensure all parties (designers, mold makers, quality inspectors) speak the same language and avoid ambiguities.

ISO 9001, ISO 13485, and Related Quality Management Standards Although ISO 9001 is not specific to injection molding, it is often a requirement or expectation in the molding supply chain. ISO 13485 is more specific to medical devices, which often involve injection molded parts. ISO 9001 – Quality Management System • ISO 9001:2015 defines a generic QMS (quality management system) framework: customer focus, leadership, engagement of people, process approach, improvement, evidence-based decision making, relationship management. • Many molders, especially those in consumer, automotive, electronics, or general products supply chains, maintain ISO 9001 certification as a baseline. (For instance, many injection molding service companies advertise ISO 9001 certification) • Advantages: consistency, traceability, audits, process control, customer confidence, ability to compete for contracts requiring ISO compliance. ISO 13485 – QMS for Medical Devices • ISO 13485:2016 is a QMS standard specific to medical devices, specifying requirements for quality and regulatory compliance in design, production, and servicing of medical equipment. • When injection molding is used to manufacture medical parts or components, adherence (or certification) to ISO 13485 is often required by clients and by regulatory agencies. Prototool’s site cites using ISO 13485 for manufacturing in medical industries. • ISO 13485 includes tighter controls, risk management, more documentation, traceability, validation, and verification requirements compared to a generic QMS. In Summary: For injection molding companies, ISO 9001 is often the baseline quality certification. If you're in medical or related fields, ISO 13485 becomes directly relevant. These standards dictate how you document, control, validate, and audit every stage of your manufacturing, but they do not prescribe particular molding process parameters.

Tolerancing and Dimensional Standards: ISO 286 (IT Grades), Others When specifying dimensions, fits, and tolerances for parts (including molded plastics), the broader ISO system of tolerances and fits (e.g. ISO 286) is relevant. The concept of IT (International Tolerance) grades is used globally, including in plastic part specifications. • ISO 286 defines standard tolerance grades (IT01 to IT18) for nominal sizes and how much variation is allowed based on size and precision class. • While ISO 286 is general (not specific to injection molding), many design engineers reference it. In fact, in some forums, engineers note that injection molded parts may struggle to meet very tight ISO tolerance grades (e.g. IT5, IT6) due to material shrinkage, molding variability, and other factors. (As discussed in a forum: “you’ll struggle to use the standard ISO tolerances … use DIN 16 901 tolerances, which account for shrinkage, etc.”) • Hence, in part specifications, designers often specify tolerances relative to what injection molding can reliably achieve, informed by ISO tolerance norms. Thus, while not strictly an “injection molding ISO standard,” ISO 286 and the tolerancing system must be understood and applied carefully in molded part design.

How “ISO for Injection Molding” Is Interpreted in Industry Because there is no single all-encompassing ISO for injection molding, industry usage of “ISO for injection molding” often means a combination of: 1. Safety Machinery Standards (e.g. ISO 20430) 2. Testing & Specimen Molding Standards (ISO 294 series) 3. Quality Management & Certification (ISO 9001, ISO 13485) 4. Terminology, tolerancing & tooling component standards (ISO 12165, ISO 286, etc.) 5. Supplemental standards / industry guidelines (e.g. SPI, ASTM, DIN, company-specific practices) Many injection molding companies advertise “ISO injection molding standards” in their marketing, which typically refers to their internal or external adherence to ISO 9001, ISO 13485, and possibly compliance with ISO safety or testing standards. For example, Protolabs lists ISO 9001:2015 and ISO 13485 certifications for their injection molding services. Prototool’s article similarly speaks about “ISO Injection Molding Standards” as umbrella term for applying ISO quality measures to reduce defects, maintain uniformity, and standardize processes across large part volumes. Prototool Their discussion focuses more on ISO as a quality / management standard rather than detailed molding-specific technical ISO. Thus, when someone asks “What is the ISO standard for injection molding?” a good answer is: a set of ISO standards rather than a single one, covering safety, test methods, quality, tolerancing, and more.

Practical Implications and Best Practices Here’s how these ISO standards matter in real-world injection molding operations: Safety & Compliance (ISO 20430) • Ensure that all new injection molding machines or retrofits comply with the safety clauses of ISO 20430 (guards, interlocks, emergency stops, safe access, hazard management). • Maintain documentation, risk assessments, safety verification, and regular audits to support conformance. Material Testing & Validation (ISO 294 Series) • When qualifying a new resin or change material supplier, molding test specimens per ISO 294-1 ensures that mechanical properties are consistent and comparable. • Use ISO 294-5 or similar to explore anisotropy or directional properties, especially for fiber-reinforced or filled polymers. • Include molding parameter records (temperatures, pressures, times) following the reporting format per ISO. Quality System (ISO 9001 / ISO 13485) • Implement a robust QMS that addresses injection molding processes: design control, process validation, change control, traceability, audits, nonconformance handling, continuous improvement. • For medical or regulated parts, satisfy ISO 13485 additional requirements (risk management, documentation, validation) to gain customer and regulatory confidence. • Use the QMS to monitor defect rates, process capability (Cp, Cpk), corrective actions, and continuous improvement cycles. Tolerance & Design (ISO 286, ISO 12165, etc.) • When creating part drawings, set tolerances achievable in injection molding, and reference ISO tolerance systems (IT grades) as guidance. • Avoid over-tight tolerances that are beyond molding capability; consult molders about what tolerances are realistic based on material, part size, features, shrinkage, and process stability. • Use consistent terminology (cavities, cores, runner, gate) per ISO tooling vocabulary (ISO 12165) to avoid miscommunication between designers and mold makers. Contracts, Customer Requirements, and Certification • Many OEMs or regulated sectors (automotive, medical, aerospace) explicitly require suppliers to be ISO certified (9001, 13485) or to follow certain ISO standards. Having documented compliance with ISO 20430, ISO 294, etc. can help in compliance reviews. • In supplier audits or RFQs, you may be asked to show how you conform to relevant ISO standards (safety, test, quality). Maintaining documented procedures and records aligned with ISO is beneficial. Limitations & Cautions • ISO standards often describe minimum or baseline requirements, not the full scope of best practice or what is optimal for a particular product or material. • Many molding challenges—warpage, cooling optimization, gate design, simulation—are not directly prescribed by ISO; they rely on engineering judgment, empirical knowledge, or other standards (ASTM, SPI, Plastics Institute guidelines, etc.). • ISO tolerancing systems (e.g. ISO 286) are general; injection molding has unique constraints (material shrinkage variability, process variation) that may limit how tightly you can apply those tolerances. • Implementation and audit focus should emphasize that documented compliance and traceability is as important as the nominal standard.

Challenges in Applying ISO Standards to Injection Molding Although ISO standards provide a solid foundation, real-world implementation can confront challenges: 1. Standards Interpretation & Ambiguity Some ISO standards (especially machinery safety) have ambiguous or broad language. Translating them into machine design or factory practice may require expert interpretation or legal guidance. 2. Overhead of Documentation & Controls Especially for smaller molding shops, implementing full ISO systems (documentation, audits, controls) can be resource-intensive. Many must balance the cost vs the business benefits. 3. Keeping Up with Revisions ISO standards are periodically reviewed and revised. Staying current is a challenge. For example, ISO 20430 is relatively new (2020). 4. Differing Customer / Regional Requirements Some customers or regulatory bodies may require adherence to related or overlapping standards (ASTM, DIN, CE directives, FDA, etc.), which may not map exactly to ISO. Harmonizing all is nontrivial. 5. Technical Gaps ISO standards often stop short of prescribing optimal technical performance (e.g. how to optimize runner systems, or simulation methods). Those gaps must be filled by internal standards, industry bodies, or research. 6. Tolerance Capabilities vs Standard Tolerancing Many molded parts cannot practically meet very tight ISO tolerance grades because of polymer behavior, shrinkage, cooling nonuniformity, etc. Thus, designers must negotiate tolerances that are both safe and manufacturable. Nonetheless, the benefits of ISO compliance—especially in regulated industries or in supply chains requiring consistency—often justify the effort.

Tips for Designers, Molders & Quality Engineers Here are some practical recommendations when engaging with ISO standards in injection molding: • Start by mapping customer / regulatory requirements: Determine which ISO standards (e.g. ISO 13485, ISO 9001, safety/machinery, etc.) are required by your clients or industry. • Adopt modular compliance: You don’t need to cover all ISO standards. Focus on those relevant to your domain (safety, test, quality, tolerancing) and expand over time. • Document Thoroughly: For standards like ISO 20430 (machine safety) or ISO 294 (test molding), maintain records, verification, risk assessments, molding logs, calibration records, etc. • Use standards as baseline, not total solution: Combine ISO requirements with good engineering practices, simulation tools, mold flow, empirical design, and industry guidelines. • Educate your team: Ensure engineers, operators, mold makers, quality personnel are familiar with relevant ISO clauses and can translate them into daily tasks, audits, inspections. • Regular audits & reviews: Conduct internal and external audits to ensure compliance, catch nonconformances, and drive continuous improvement. • Engage with standard updates: Monitor revisions in relevant ISO standards (safety, testing, materials) so you aren’t caught by obsolescence.

Summary & Takeaways • There is no single ISO standard that fully encapsulates all aspects of injection molding. Rather, a constellation of ISO standards apply, each governing particular facets—machine safety (ISO 20430), test specimen molding (ISO 294 series), vocabulary/tooling (ISO 12165), tolerancing (ISO 286), and quality systems (ISO 9001, ISO 13485). • ISO 20430:2020 is the primary standard addressing safety for injection molding machines. • ISO 294-1 and ISO 294-5 are key for molding of standard specimens to ensure reproducibility of material property data. • Quality management via ISO 9001 is often mandatory in production supply chains; ISO 13485 is essential when producing medical device components. • Designers must balance ISO tolerancing systems (e.g. ISO 286) with the real constraints of injection molding processes. • Implementing ISO standards demands discipline: documentation, audits, training, process control, and continuous review. In practice, saying “We comply with ISO standards in injection molding” means that your operation is aligned with the relevant ISO norms—machine safety, specimen testing protocols, quality systems, and proper tolerancing practices—while filling in the engineering gap with domain expertise, simulation, and rigorous process control.

Selective Inhibition Sintering (SIS) is an additive manufacturing (3D printing) process that offers an alternative to more conventional powder-based metal or polymer sintering techniques like Selective Laser Sintering (SLS). Developed by researchers (notably at the University of Southern California), SIS seeks to produce parts by inhibiting sintering (or melting) in certain regions, rather than directly sintering or melting all regions via high-energy sources (lasers, electron beams, etc.). What is SIS in 3d printing? In simpler terms, in SIS you deposit a base powder (metal or polymer), then selectively apply an inhibitor over the areas you don't want to sinter. Afterwards, you subject the whole thing to a sintering furnace (heat), which fuses the non-inhibited regions to form the final solid object, while the inhibited regions remain loose or non-sintered, acting as sacrificial or “support” material. After sintering, the loose material can be removed, leaving the desired geometry.

How SIS Works — The Process Steps Here is a breakdown of the steps involved in SIS: 1. Powder Bed Preparation A layer of base powder is spread onto a build bed. The powder could be metal, polymer, or ceramic. The properties of the powder—particle size, sintering temperature, flowability—are critical. 2. Selective Inhibitor Deposition Over that powder layer, an inhibition agent (sometimes delivered via an ink-jet printhead) is deposited. The inhibitor is applied only to regions where you do not want the powder to sinter during the sintering step. The geometry of the inhibitor pattern corresponds to the “outside” or unwanted powder regions.  This inhibitor can be a liquid solution (e.g. sucrose + surfactant, or other chemical) in early polymer/metal versions.  For ceramics, dry powder inhibitors are also used (because high sintering temperatures can make liquid inhibitors impractical). 3. Layering / Repetition Additional layers of base powder are added, and inhibitor gets applied in each layer as needed, building up the 3D part. The shape of the inhibitor region between the region to be sintered and the surrounding powder forms essentially a temporary mold or shell/moat. 4. Sintering The whole build — including both inhibited and non-inhibited regions — is placed in a furnace and heated to the sintering temperature of the base powder. Because inhibited regions have been treated (or coated) to prevent or slow down sintering (or require a higher temperature than is provided), only the non-inhibited powder fuses into a solid component. 5. Post-Processing / Removal of Loose Powder After sintering, the inhibited (non-sintered) powder, which did not fuse, remains loose or only weakly bound. This powder is removed (e.g. by brushing, sand-blasting, or simple mechanical removal) leaving the final object. 6. Finishing As with other metal/ceramic sintered parts, depending on required tolerances and surface finish, additional finishing steps (machining, polishing, possibly secondary sintering or annealing) may be needed. SIS’s output depends on the fidelity of the inhibitor deposition, powder characteristics, and sintering behavior.

Why “Inhibition” Instead of Direct Fusion? SIS inverts some of the typical approach in powder sintering / fusion processes. Most conventional powder bed fusion (PBF) or sintering-based AM methods use a heat (laser, electron beam, or other) to selectively fuse or melt the powder in target regions (for example SLS for polymers, Direct Metal Laser Sintering (DMLS) for metals, etc.). SIS instead selects where not to fuse by applying an inhibitor, which means that: • Only the “negative” space (the region outside the desired part) needs to be defined explicitly via inhibitor deposition rather than “flooding” the whole powder bed with energy except in unwanted zones. • The energy source (sintering furnace) can be relatively simple compared to precise lasers or beam systems. • Potentially lower cost, simpler hardware, and maybe better scalability for larger parts, because the challenge of focusing and scanning a beam is replaced with an inhibition mechanism + furnace sintering.

Advantages of SIS over Traditional Methods Selective Inhibition Sintering offers a number of potential benefits, particularly for certain applications or use-cases. Some of the key advantages are: 1. Lower Equipment Cost Because the process does not require high-power lasers, scanning optics, or electron beams for selective melting, the hardware cost can be significantly reduced. The sintering furnace, controller, powder spreader, and inhibitor deposition mechanism are simpler in many respects. 2. Potential Speed Gains for Certain Geometries Since only the part boundary (i.e. inhibitor deposition) needs precise patterning, and the interior of the part is just base powder, there may be less work per layer, potentially speeding up deposition for large solid volumes. 3. Material Efficiency / Waste Handling The use of loose powder in non-inhibited regions means that the same base powder is being used for both part and surrounding material; only the inhibited powder (or inhibitor) is sacrificial. If managed properly, this can reduce some of the complexity of removing support structures or worrying about over-spray or beam width effects. 4. Scalability for Larger Parts As the part size increases, laser or beam systems often need more energy, face issues of focus, heat diffusion, scan path, etc. SIS avoids some of those drawbacks because the sintering happens more uniformly in a furnace rather than by scanning. 5. Flexibility of Materials SIS has been explored not only for metals and polymers but also ceramics. For ceramics, applying an inhibitor helps in creating viable green parts and then sintering. This can avoid some of the complexity of binder-based ceramic AM or laser sintering ceramics, which can suffer from high energy, warpage, and other defects. 6. Simplified Support / Shape Boundaries Because the inhibitor effectively defines the “outside”, support structures or over-hangs might be handled in new ways, possibly reducing the need for adding physical supports in some cases. The loose powder outside inhibited regions acts somewhat like a support until removed.

Challenges, Limitations & Technical Hurdles Like any emerging technology, SIS also faces material, processing, and design challenges that must be addressed before it can be widely adopted. Some of these are: 1. Inhibitor Material & Effectiveness  The inhibitor needs to sufficiently prevent sintering or melting in treated areas without interfering with desired regions.  It must have stability under sintering temperatures (i.e. either a higher sintering/melting point, or otherwise not degrade).  For liquid inhibitors, issues like over-penetration (inhibitor seeping beyond intended boundary), diffusion, and residue must be managed.  For ceramics or higher temperature sintering, liquid inhibitors often become ineffective or problematic; dry powder inhibitors are one possible solution but bring their own handling issues. 2. Resolution & Precision  The fidelity of the final part depends heavily on how accurately the inhibitor can be deposited. Any misalignment, overspray, or blur will degrade the boundary between the sintered part and non-sintered powder.  Powder particle size also matters: larger particles reduce resolution; very small particles are more expensive, more difficult to handle, more prone to agglomeration or flow issues. 3. Shrinkage & Distortion  Sintering processes usually cause shrinkage; parts may deform. The presence of non-sintered envelopes or boundaries defined by inhibitors introduces additional complexity in predicting how the final geometry will result.  Uniform heating in furnace vs localized sintering may still cause temperature gradients, warpage, or defects if not well controlled. 4. Post-Processing of Loose Powder / Cleanup  Removing inhibitors and non-sintered powder cleanly may be difficult, especially in fine features or internal cavities.  The leftover powder may be contaminated by inhibitor, which could complicate reuse of powder or recycling. 5. Material Cost & Powder Handling  Some powders (especially metal or ceramic powders) are expensive, sensitive (oxidation, moisture), and pose health/safety issues. Handling large amounts safely, or reusing powder, is nontrivial.  The inhibitor itself has to be managed, stored, and disposed of appropriately. 6. Thermal Management  Sintering temperatures for metals/ceramics are high; thermal gradients, furnace uniformity, and heating rate control are all critical.  The inhibitor’s thermal profile must be well known to ensure it behaves as expected (i.e. remains non-sintered or at least not fused) during heating. 7. Throughput / Cycle Time  Although SIS promises some speed gains, the overall process (powder spreading, inhibitor deposition, furnace sintering, post removal) may still be relatively slow for certain applications compared to fast PBF systems (for thin/layered parts).  Cooling time, sintering dwell time, and post-processing add to total production time. 8. Software & Process Control  You need good software to convert CAD to instruction layers for both powder and inhibitor deposition.  Proper control of deposition, environmental conditions (e.g. temperature, humidity), and monitoring is necessary.

Applications and Use Cases While still largely research-stage in many respects, SIS has potential (or demonstrated) applications in several fields: • Metal 3D Printing for Cost-Sensitive Use SIS could allow production of metal parts with lower capital cost machines, enabling smaller firms or labs to do metal AM with less expensive equipment. • Ceramic Parts Fabrication Ceramics are hard to print via traditional techniques without extensive post-processing. SIS offers ways to make complex ceramic parts with less need for binders or extremely high-energy laser sintering. • Large Structural Components For large parts where lasers/EB machines have issues (power, focal accuracy, scanning speed), SIS may offer a route to scalable production. • Prototyping / Research Early prototyping of metal/ceramic shapes where cost or equipment availability is limited. • Space / In-Situ Manufacturing Some works mention SIS being particularly interesting for in-space or off-Earth manufacturing (lunar regolith, etc.), since available raw materials could be used, and simpler equipment might be more feasible.

Research Highlights & Case Studies Some interesting studies and results include: • The original SIS development for polymers and metals by Khoshnevis et al., which demonstrated that SIS can produce high-quality parts and promised disruptive potential for metal AM. • SIS applied to ceramics: in “Selective Inhibition Sintering for ceramics,” the research shows using dry powder inhibitors (e.g. magnesium oxide, aluminum oxide) to delimit the sintering boundaries. Preliminary experiments showed feasible separation of parts from redundant powder and usable mechanical properties. • Tests using lunar regolith simulant: studies have explored SIS as a way to manufacture building/landing-pad tiles in space environments using in-situ resources. The idea is the base powder being something like lunar regolith simulant, and using an inhibitor (of higher sintering point) as the boundary. After sintering, parts are separated from the uninhibited (non-sintered) powder.

Practical Considerations When Using SIS For anyone thinking of using or developing a SIS process, here are practical points to pay attention to: 1. Powder Selection and Preparation  Particle size distribution: fine, uniform powders help with resolution and uniform sintering.  Cleanliness: no moisture, contaminants. 2. Inhibitor Design  Chemistry: effective inhibition without interfering with base powder.  Delivery mechanism: inkjet heads, spray, or nozzles for dry powder.  Thickness and fidelity: minimal over-penetration; sharp boundaries. 3. Sintering Furnace Design / Thermal Control  Uniform temperature distribution.  Proper heating and cooling rates to reduce thermal stresses. 4. CAD / Layering / Slicing Software  Must support the dual-material/layer deposition: base powder + inhibitor patterns.  Must be able to generate inhibitor “shells” or boundary paths accurately. 5. Post-Processing & Purity  Removal of non-sintered powder and inhibitor.  Surface finishing and any required densification. 6. Quality Control & Testing  Tests for density, mechanical properties (strength, toughness).  Dimensional accuracy vs. CAD model.  Material composition (to ensure no unwanted residual inhibitor contamination). 7. Safety & Handling  Powder handling safety (especially metals, ceramics).  Inhibitor materials: chemical safety, disposal.  Thermal equipment safety.

Limitations & Open Research Questions While promising, SIS has not yet become a widespread industrial standard. Key open questions include: • What is the long-term mechanical performance (fatigue, toughness) of SIS parts compared to fully laser fused ones? • How fine can the resolution be pushed (both in boundary sharpness and internal feature detail)? • Can inhibitor materials be standardized, cost-effective, and easily applied at scale without compromising performance? • How efficiently can uninhibited powder / loose powder be recycled or reused? • What are the limits in terms of part size, complexity, overhangs, internal channels, etc.? • What are the economics when considering full process cost (powder + inhibitor + furnace + post-processing) vs conventional PBF or other AM methods?

Future Prospects Given its advantages and challenges, here are some likely areas for future development of SIS: • Advanced Inhibitor Materials & Deposition Systems Better inhibitors that are reliable, less costly, easy to deposit accurately, perhaps self-limiting, maybe even smart inhibitors responsive to temperature. More precise deposition hardware (improved inkjet, spray, or powder nozzle systems). • Hybrid Processes Combining SIS with other AM methods; for example, using SIS for bulk volume or structure, then using laser sintering or other techniques for finer detail or finishing. • Application-Specific Use Cases Industries where cost reduction for metal/ceramic AM is very desirable: aerospace, space exploration, architectural ceramics, large manufacturing, maybe construction. • Supply Chain & Material Ecosystems Better powders, better inhibitor supply, better recycling of powders, standardization of process materials to reduce cost and variability. • Automation & Digital Control Improved process monitoring, closed-loop control of temperature, inhibitor deposition, furnace atmosphere etc. to ensure consistent parts. • Regulatory & Certification For critical parts (medical, aerospace), SIS parts will need to prove their reliability, structural integrity, and reproducibility.

Conclusion Selective Inhibition Sintering (SIS) is an intriguing and potentially disruptive technology in the additive manufacturing landscape. It offers a different route to produce metal, polymer, and ceramic parts, by inverting the typical “selective fusion” approach and instead using selective inhibition to define where sintering should not occur. This can lower equipment complexity, potentially reduce costs, and offer scalability advantages, particularly for larger parts or those made from ceramics. However, SIS is still a developing technology. Its success in industrial adoption will depend on solving challenges around resolution, inhibitor materials, thermal management, powder reuse, and overall process economics. But given the research to date, SIS is a strong candidate for future growth, especially in sectors where traditional metal/ceramic 3D printing is costly or impractical.

Hi everyone,

Lately I’ve been diving into GPU performance testing, especially for shader-heavy graphics (fractals, ray-marching, etc.), and I found a free online tool called Volume Shader BM Benchmark that I think is pretty useful.

Here’s what I liked about it:

Runs right in the browser with WebGL, no install needed.

Lets you tweak things like resolution, shader iterations, step size so you can push your hardware.

Gives detailed metrics like frame rate & frame time, plus lets you share a link so others can reproduce your exact settings.

The presets (Ultra Low → High) make it easier to compare different devices without manually tuning everything.

If anyone’s looking to compare GPUs, test rendering stability, or just see how different graphics cards handle heavy shader loads, this is worth trying. Curious if others have used it—how did your GPU hold up?

Hi everyone,

I often work with hours and minutes, and sometimes it gets confusing when I need to calculate totals or compare time spans. I recently came across Time-to-Decimal Converter, which instantly turns regular time into decimals (for example, 2 hours 30 minutes → 2.5 hours).

It seems really handy for quick math, spreadsheets, or even tracking personal projects. Has anyone else here tried this approach? Do you find decimal time easier to use?
