Hi Vicoos,
Sorry for getting back to you just now!
To answer your question: With Open Material Mode you would indeed be able to print Silicone 40A Resin on a Form 3L without tampering with the resin cartridges (which could only work temporarily, since the cartridge will be locked once 1 L of resin has been printed from it).
Open Material Mode allows you to print with any 405 nm resin and it’s the solution we offer for experimenting with non-validated materials, but please note that the tank needs to be filled manually. You can find more information on the process here.
That said, the print settings would still need to be created in the Print Settings Editor, as we do not have validated print settings for Silicone 40A on Form 3L. With low durometer materials, it’s very challenging to reliably print large parts, and our validation standards are high, which is why we have not published official settings.
For the Form 4L, our engineers have shared some unvalidated print settings for Silicone 40A, Alumina 4N, and True Cast Resin in this post. Please note that these settings have not passed validation, so print success still cannot be guaranteed.
The Form 3L’s different print engine makes achieving usable settings an even bigger challenge, so we don’t recommend it. If you choose to proceed at your own risk, we’re happy to look at any results you’re willing to share on this thread to pass on to our materials team.
We hope this helps!
Best,
Sophia
