What Does Biocompatibility Compliance Mean For Our Latest Resin Removal Detergent?

The Proven Resin Removal Detergent: PLM-403-SUB
PostProcess Technologies’ PLM-403-SUB is the world’s only detergent specifically developed for resin removal on 3D printed photopolymer parts. As an instrumental element within several PostProcess solutions, PLM-403-SUB is an effective alternative to solvents like isopropyl alcohol (IPA) and tripropylene glycol monomethyl ether (TPM) for resin removal in SLA, DLP, and CLIP print technologies. Recently, this detergent has officially been recognized as compliant with ISO standard 10993 for the evaluation of biocompatibility by Toxikon Corporation. What exactly does this mean for the proven detergent?

With this new demonstration of compliance with requirements for biocompatibility, additive manufacturing users can enjoy the Submersed Vortex Cavitation (SVC) solution’s new industry standard for maintaining or seamlessly incorporating fully biocompatible processes. Particularly, this will prove impactful for those in the dental, medical, and even audio realms, as materials with applications that come in direct contact with the human body are under ISO 10993: Biological Evaluation of Medical Devices.

In compliance tests, parts were printed with biocompatible Formlabs Surgical Guide resin, and cleaned with PLM-403-SUB. When evaluating for cytotoxicity, sensitization, and irritation, the test articles elicited no reaction with any subjects, making them successfully compliant with requirements for biocompatibility approval of medical devices per ISO 10993.

More on This Proven Detergent
This detergent plays a significant role in PostProcess’s patented SVC technology, combining with software intelligence and a vortex pumping scheme to ensure that 3D printed parts are uniformly, consistently, and reliably exposed to detergent and cavitation. As a result, parts are finished precisely and consistently, requiring little to no manual labor.

Though the overall SVC solution bolsters a safer workflow thanks to minimized manual labor, this detergent has enhanced safety features like a high flashpoint (220°F, 104.4°C) which categorizes it as a non-flammable liquid. The new compliance rating furthers the detergent’s standards of safety. Thanks to the automated nature of the solution and the long-lasting life of the detergent (PLM-403-SUB has significantly better longevity [capacity by weight of resin in solution at 10 minutes] than all other typical solvents [i.e., IPA, DPM, TPM] used to remove uncured resin from printed parts), this technology is renowned for providing a safer, more efficient post-printing process that will remain sustainable even as production volumes scale.

Achieving this compliance perpetuates PostProcess Technologies’ dedication to the seamless integration of their automated solutions and an overall more streamlined additive workflow. For more on our mission to equip additive for Industry 4.0, visit our “Why PostProcess” page.

Shaping Additive with Collaboration: The Carbon-Compatible PostProcess DEMI 910 Is Here

It’s no secret that Carbon® is one of the world’s leading names in additive manufacturing. Their proprietary Carbon Digital Light Synthesis™ (Carbon DLS™) photopolymer 3D printing process is globally renowned for its ability to produce high-performing consumer and industrial parts at production volumes. As a leading 3D printing company, new opportunities for improved scalability continue to grow. Seeing the opportunity to offer increased productivity and improved end-part consistency to their users, Carbon paired up with PostProcess Technologies to develop an automated resin removal solution for the Carbon ecosystem.

A Custom Solution for Carbon
The resulting solution, now released, is the PostProcess® DEMI 910™. At the core of the solution is PostProcess’s signature patented Submersed Vortex Cavitation (SVC) technology. This technology employs multiple automated energy sources like a vortex pumping scheme and software-driven ultrasonics to finish Carbon parts effectively, in as little time as possible.

What makes this solution exclusively suited for the Carbon L1 printer and M2 printer? The true differentiating point is in the proprietary fixture design. The DEMI 910 is built with a fixture suited to support the exact specifications of the L1 and M2 build platform. This means the solution can seamlessly wash an entire build from a Carbon L1 printer, or two build platforms from a Carbon M2 printer, without ever having to remove printed parts from the build tray. This ergonomic feature improves productivity for technicians and further lessens post-print cycle times.

Leveraging Chemical Energy
In terms of chemical energy sources, the DEMI 910 will be outfitted with a Carbon-specific resin removal detergent, proven for effective use on Carbon EPU 41, EPX 82, MPU 100, RPU 70, RPU 130, DPR 10 and UMA 90 as well as LOCTITE® 3D IND 405 Clear certified for Carbon printers. Developed by our in-house PhD chemists, PostProcess’s resin removal detergents are formulated especially for additive manufacturing and created to be more sustainable than traditionally-used solvents like isopropyl alcohol (IPA).

Compared to IPA, this detergent has outstanding longevity, equating to more infrequent detergent change-outs. A higher flashpoint also makes the detergent less hazardous to work around. The PostProcess team took care to ensure the chemicals would be pleasant to work with. So, this detergent carries a lower vapor pressure and overall more enjoyable scent than something like IPA.

Driven by Data Intelligence
The effectiveness of the Submersed Vortex Cavitation (SVC) technology is driven by our proprietary AUTOMAT3D® software. At the core of this software design is data collected from hundreds of thousands of benchmark parts of all 3D print technologies and most print materials. With this data, the DEMI 910 optimizes recipes, and works with sensors that allow for real-time adjustments of the system’s Agitation Algorithms. Together, these functions allow customized parameters to intelligently tailor resin removal for the unique needs of each part.

We are excited to partner with a company that’s equally invested in innovating scalability for the data-driven future of additive manufacturing. We look forward to the continuous collaboration, and further aligning our full-stack solutions to Carbon’s ever-growing resin and printer portfolio.
