No-Wash Revolution: Form 4 Sets the Professional Standard, HeyGears Captures the Studio Market

The End of the Messy Workflow?

If you've ever used a resin 3D printer, you know the struggle. The sticky, complicated, and sometimes dangerous cleanup process is a real pain. You have to carefully wash your prints in flammable liquids, dry them properly, and then cure them under special lights. This process needs lots of space, good air flow, and you have to be okay with making a mess. As we move through 2025, companies are taking two very different approaches to fix this problem. This isn't just about new printers – it's about two completely different ideas on how to make the whole process easier.

This article looks at these two different paths. We'll examine how the Formlabs Form 4 system makes the traditional workflow almost perfectly smooth, making it the go-to choice for serious professional work like dental and medical applications. At the same time, we'll explore how the HeyGears Reflex and its "no-wash" resin are creating a much simpler process that appeals to prosumers, artists, and hobbyist studios. By the end of this analysis, you'll understand the unique benefits and drawbacks of each approach, helping you figure out which philosophy works best for your specific needs, whether that's a regulated professional environment or a creative studio.

The Professional Standard

The Formlabs Form 4 system is built for a specific type of user: dental labs, medical device engineers, product design companies, and manufacturers. For these professionals, accuracy, consistency, and proven material properties are absolutely essential. "Efficiency" isn't just about skipping steps – it's about complete reliability, incredible speed, and validated processes from start to finish.

The philosophy behind the Form 4 is total system optimization. It's a closed, highly-integrated system where the hardware, software, and materials are all developed together to work as one unified unit. This ensures that the results promised in the specifications are the results you actually get on the build plate, every single time.

The Workflow in Practice

The Form 4 workflow starts with the Low Force Display™ (LFD) print engine. This technology is what makes the system exceptionally fast and reliable, allowing most prints to finish in under two hours while maintaining excellent surface finish and precise dimensions.

Post-processing, which often slows down other systems, is a controlled and automated stage in the Formlabs system. The Form Wash and Form Cure stations aren't add-ons but essential parts of the system. They use precise, pre-tested cycles to ensure that parts are perfectly cleaned and cured to achieve their specified mechanical and, when needed, biocompatible properties. This isn't a chore – it's a repeatable, automated science.

Connecting everything is the software. PreForm software makes print preparation surprisingly simple, with smart support generation and part positioning. The cloud-based Dashboard allows for remote monitoring, managing multiple printers, and detailed tracking of material usage and print success rates, providing the process validation and documentation required in professional and regulated environments.

The Material Advantage

For professionals, the Form 4's extensive library of specialized resins is a key feature. This includes a wide range of biocompatible materials for dental and medical applications, certified for skin or mouth contact. It also features strong engineering-grade resins like the Tough and Durable families, which offer predictable, verifiable performance that can compete with injection-molded plastics.

In regulated industries, a closed material system is a major advantage. It guarantees that the resin you're using is the exact formula that was tested and validated, ensuring quality, consistency, and a single point of contact for support. It removes variables and solidifies the process, making it a trusted tool for critical applications.

The Studio Challenger

The HeyGears Reflex targets a different but equally demanding user: high-end hobbyists, miniature artists, product prototypers in small studios, and prosumers. These creators demand high-quality output but place huge value on workflow simplicity, a smaller physical footprint, and reduced operational overhead.

The philosophy here is radical simplification. The core innovation driving the Reflex system is its "no-wash" resin. This material is designed to come out of the printer with a dry, non-sticky surface – a revolutionary concept that tackles resin printing's biggest problem. The user benefit is immediate and significant: the complete elimination of isopropyl alcohol (IPA) or other solvents, the washing station itself, and the associated mess, fumes, and hazardous waste disposal challenges.

The Streamlined Process

The "no-wash" workflow is incredibly efficient. The process is reduced to three simple steps: Print, Remove Supports, and Final Cure. This is very different from the traditional multi-step process. The time saved is significant, but so are the savings in space and supplies. A studio no longer needs a dedicated, ventilated area for washing, nor does it need to buy and store large volumes of flammable solvents. This dramatically lowers the barrier to entry for clean, efficient, and high-quality resin printing in smaller, more limited environments.

The Material Question

The "no-wash" resin naturally raises questions. How does it work? The chemistry is complex, but the result is a resin that cures to a non-sticky state when exposed to the printer's light source, leaving behind very little liquid residue. The surface finish directly off the printer is remarkably clean, allowing users to proceed almost immediately to support removal and final curing.

However, as of 2025, this revolutionary approach comes with trade-offs that users must consider.

• Performance: The mechanical properties of early "no-wash" resins, while impressive, may not yet match the full range of performance offered by specialized traditional resins. For applications requiring extreme strength, flexibility, or impact resistance, the established engineering-grade materials in a traditional workflow still hold an edge.
• Detail & Accuracy: While detail resolution is excellent, the unique chemistry could, in some specific cases, present different considerations for achieving ultra-fine negative features or maintaining the tightest dimensional tolerances compared to a fully washed and cured part from a traditional system.
• Availability & Cost: The range of available "no-wash" materials is currently more focused than the vast libraries offered by established ecosystem players. The cost per liter is also a factor, though it must be weighed against the significant savings from eliminating solvents and dedicated washing hardware.

A Tale of Two Philosophies

To summarize the core differences, this comparison table helps match user needs to the right system philosophy.

The Future Is Now

This split in the market is a clear sign of maturity. The 3D printing industry is moving beyond one-size-fits-all solutions and developing highly specialized tools for distinct user segments. The Formlabs Form 4 vs HeyGears Reflex dynamic is a perfect example of this trend. Both companies are innovators pushing the industry forward on parallel tracks, a development that ultimately benefits all users by providing more tailored choices.

Looking ahead to 2026 and beyond, several questions will shape the landscape. Will the material properties of "no-wash" resins evolve to match or even exceed the best traditional resins, making them viable for engineering and regulated applications? Conversely, will professional systems like those from Formlabs begin to incorporate elements of this simplified workflow, perhaps through new material chemistry or more advanced, all-in-one post-processing hardware? We are also seeing the rise of other trends, including greater automation in part removal, AI-driven software optimization, and a growing focus on material sustainability, all of which will continue to redefine what "efficiency" means.

Choosing Your Workflow

Ultimately, the choice between the Form 4 and Reflex approaches is not about which is definitively "better." It is about which workflow philosophy is the right fit for your specific context, budget, and application. The decision is no longer just about the printer – it's about the entire process.

• For the Professional: If your work demands certified materials, uncompromising accuracy, and a workflow where every step is validated, repeatable, and documented, the path of the integrated ecosystem is the established professional standard. The goal is a reliable, end-to-end manufacturing process.

• For the Studio Creator: If your primary goal is to move from a digital design to a physical object with the least amount of friction, mess, and intermediate steps, the "no-wash" revolution offers a compelling and streamlined future. The goal is maximum creative output with minimum operational hassle.

The "No-Wash Revolution" is not a single event but an ongoing evolution. The Formlabs Form 4 vs HeyGears Reflex represent two powerful, different visions for the future of resin 3D printing. By understanding these two leading approaches, users are better equipped than ever to invest in a system that truly serves their purpose.
