Making a Platinum Silicone Mold of an SLA Printed UV-Cure Model

- Making rubber molds and multiple castings of 3-D prints made with SLA is often a goal of model makers. As 3-D printing technology using SLA resin continues to evolve, there are best mold making practices that can help you be successful.
Platinum silicones offer the advantage of dimensional stability and long-term library life. However, platinum silicones are more subject to cure inhibition against a UV cure resin model that is not fully cured.
Smooth-On platinum cure silicones will work against most SLA 3D print models with one caveat; the printed model must be fully UV cured. When models are done printing, they are not fully cured.

Absolutely never pour 3D printer resins down the drain, or even wash them there. It is a serious long-term hazard to the water system. Fully cure your prints before getting uncured resin onto things.
Ever wondered how to mold an SLA print to cast resin reproductions? Check out our latest video!
Well done!
Thanks!!!
Hey guys, I've found that the Glass Reinforced Resin actually doesn't cause cure inhibition. My friend uses it, I'll try and get the brand and model number from him. But it's been a life saver!
Found it, FormsLab Rigid 4000. I've had a few prints that just after UV curing and typical post-print stuff, I could cast directly with MoldStar 15, 30, Rebound 25, etc. No inhibitions!
@@MaggiesBirds thanks for sharing!
@@MaggiesBirds Thank you, I will be trying this resin
How is the surface finish for this resin though? Im not sure what glass reinforced means so im curious if it can still produce a really smooth finish.
Sweet, finally no more guessing!
Hey guys, just an FYI PSA kind of thing. Resin should NEVER be washed down the public drains - it is HIGHLY toxic and persistant in aquious environments. Even after you have rinsed it in IPA, any liquid that touches an uncured model should be considered contaminated. Waste water should be cured with UV and allowed to evaporate.
Odd that they're doing it in what looks like a home
Seconded! I go to great pains to make sure resin is NEVER going down any drain in my home. Anything that may have touched an uncured model is FULLY CURED before being put in the trash. The fact that Smooth-On put out this video is incredibly irresponsible and makes me rethink who I will buy my rubber from in the future.
@@LG-vd8se Hate to tell you this but every other supplied most likely does the same - they just don't have videos. If you care about the enviroment then you shouldn't even be using any of these types of products at all anyway as once they break or in the case of movie props they will just end up in the trash. (i work in the movie industry and it is extremely wasteful).
@@corail53 Your argument doesn't make sense. Throwing away cured resin parts has a substantially lower environmental impact than dumping a non-degrading bio hazard that is liquid resin straight into the water system. Just because you negatively impact the environment by purchasing paint doesn't mean it's justified to also pour paint thinner down the drain also. Nobody is perfect, but when it comes to toxic chemicals, proper disposal is critical. It may also be illegal to pour 3D printer resins down the drain depending on where you are.
Hi, you can try post curing the 3d print under water - the water displaces oxygen on the surface, which may otherwise cause cure inhibition in the uv- resin. This way, you might not need to coat your print - but the chosen silicone rubber is still a factor.
I'll pass this on to our 3D print expert in house and ask him to give this a try. Thanks for the advice!
Wish I had seen this before buying your InhabitionX stuff that isn't working with SLA prints😑
What is the difference between platinum cure and tin cure? What does it even mean?
If "platinum silicones are more subject to cure inhibition against a UV cure resin model that is not fully cured." then how are tin silicones for use with UV cured resins? Should I use either platinum or tin?
Tin silicone can be used.
Super
Is there any difference from a non resin 3D printer?
It can depend on the material you use. I've found ABS and PLA do not need any post-processing, you can make a mold with a part straight from the printer.
Nice.. what colour pigment do you use
SO-Strong or UVO colorants
