There's a workaround that avoids any platinum rubber cure inhibition. It works with any UV Resin for 3D printing. When reaching the UV light cure stage, first submerge the 3D parts in water (clear glass container) and then place the UV light on top. I cure it until the resin looks a little cooked, i.e. gets a brown-ish color. Nobody really knows why this works. Some theorise that under UV light the water molecules change the orientation of the surface molecules of the plastic in such a way that the inhibitory molecular structure remains on the inside. Or maybe the inhibitory molecular structure attaches to the water molecules, thus washing them away.

I don't know how anyone watching your videos wouldn't become a superstar .

Hello sir i am interested .how can i get small casted moulds please ??or how can i get liquid silicon rubber for moulds please help me please ....????

[FranklyPeetoons]

These videos make my mouth water. While watching them, I often eat a sammich. I pretend as if I'm eating the actual molding material. That stuff always looks so delicious.

Thank you for this video. I ran into the problem of my silicone rubber not curing with resin prints. This may solve my problem.

I am happy you posted a new video. Welcome back! Hope the hiatus brought back your energy and passion for YT.

Now this is the kind of test I love to see! I have been using platinum cure silicone with resin prints and have run the gamut of challenges that it brings. I usually get by with extra caution in my cleaning process (using alcohol only) and letting the print off-gas for a while, but sometimes I have also had to use Inhibit-X for this reason. The X in Inhibit-X must stand for expensive, though, because it costs a lot. It also changes the surface texture of the print, which the mold picks up. So this silicone from Siraya Tech seems like a wonderful solution and I will definitely switch over!

I can confirm this product works wonderful. Its available on amazon as 1kg bottles, hopefully they'll release a larger size soon.
Its a shore 25 silicone those. This wont flex and demold as easy as other products.

Do you have a witness cup protection program?

I was beginning to think YouTube unsubbed me, but here you are, yay!

[TheZahnputz]

since oxygen contact causes the cure inhibition in UV-resins - which then causes the cure inhibition with platinum silicones - the postcuring submerged in water is the crucial step! there are quite a few options, e.g. "elastosil vario..." from wacker, that also work great with sla prints.

I only use siraya tech resin, I will need to get my hand on some of there silicone. thank you for video

[Theexplorographer]

Thanks Robert! Great video and great to see you in long form.

Use talc powder on seam and it will align perfect every time.

This is great to hear, I hate tin rubber for its shelf life. Takes no time at all before what’s left in the bottle is completely useless

[BaronMcCausland]

Quote of the Video: "Mankind's Most Magnificent Material" LOL! Good one, Robert!!

[alexmakhoul]

Can't wait to get my hands on this, hope it's available in the UK soon

[tanterouge]

Sure am interested to see how it performs with resin from other companies as well!

[leahqueen]

I'm a novice and learning, but now I know the difference between platinum rubber and tin cure. Thank you!

What is "sticky wax"? Where can I get some?
