Thanks for the answers Henry! A soak in water seems reasonable…when working with TPM in the past I had to rinse them in IPA afterwards which was a pain to store two solvents.
Good to know about recycling. I will likely wait until after that has been confirmed to add into my workflow then.
Cheers.
Does this new wash solution have better performance in preventing thin sections of like tough 2000 and other IPA absorbent resins from deforming during wash as well compared to IPA?
And wash performance is about comparable with IPA?
@henryqiu , the SDS don’t say much. Everything is a trade secret and is not possible to know whick of the trade secrets creates or dosen’t create a hazard. Not sure If even makes sense to show this to EHS team.
It is available the SDS file according european estandards.
Thanks
Resin Washing Solution may swell/deform parts if exposed to resin for a significant amount of time (i.e., left ‘wet’ for > 8 hours), but if the solution is rinsed off with water within that time it should not deform parts in the wash.
The wash performance is comparable with IPA. Here is a testimonial from a high-volume dental lab:
“I’m very happy with the results so far. The solution-cleaned prints are the same or slightly better than washes done in IPA. There’s little to no odor, but more importantly there’s no fumes; the overall work environment is much, much more pleasant without IPA!”

Is it even legal for a dental lab to be using this stuff if it hasn’t been approved for biocompatibility?
While some information is listed as a trade secret in the SDS, the EU SDS provides more details under European standards, including the specific hazardous components in Section 2. This should give your EHS team the information they need for assessing any potential hazards. We’re working on making the relevant SDSs more easily accessible on our product pages, but please refer to the one linked above for now.
Great question! While biocompatible materials do require specific validation for medical or intraoral use, many dental applications don’t require biocompatible resins/workflows. Dental labs often use Formlabs printers and materials for dental models like thermoformed appliances or restorative models for fit-testing dental appliances. For example, many dental labs use Fast Model Resin and Precision Model Resin for creating molds for vacuum forming and other non-intraoral purposes. Neither of those resins require a Form 4B or biocompatible workflow/certification, making them suitable for use with Resin Washing Solution.
Re: workflow. Unlike IPA Form Wash Solution doesn’t evaporate quickly. After placing build platform in a Form Wash 2 can I just move
the build plate back to my Form 4 or do I need to wash the build platform with water. I am concerned about residual wash solution interacting with resin.
Build Platforms washed in Formlabs Resin Washing Solution need to be dried with a clean paper towel, cleaned with IPA, and wiped again to ensure it is clean. Any leftover solvent on the BP can mix with the resin and cause print failures.
