SLA 3D-printed mold for silicone casting. Printed on a Formlabs Form 4L using Formlabs Standard Clear Resin. Great video by Karl Eriksson from our partner Addinor. One of the leading experts in the Nordics in 3D printing.

@Grok ¿Cómo se prepara un "silicón" casero?

May I ask (and this is real question from ignorance), why all the bolts? Why not just shove in a vice? (you would still be able to see enough) [I've made lots of moulds in my life, including materials that expand, but not silicone, perhaps I'm missing things]

The main reason is getting an even force on the mold; with a vice you will normally just clamp in the middle, so for a bigger mold the bolts make sure that you have a good seal between the mold halfs in all areas. Also, your vice won't be blocked for hours while silicone cures!

No self-respecting person who makes things has only one vice.

Stark! Aber sowas lohnt sich kaum selbst herzustellen. Die 3D-Druck-Community hat unendlich viele Ideen, aber es fehlt am Verkaufsgeschick! Damit ist bald Schluss! 🚀

Be careful with resins and the type of silicone cure... I have experienced cure inhibition using standard ABS resin and platinum-cured silicone. I have learned, through failures, that there are sulfur compounds in the standard and ABS resins that dont play nice with the platinum. I have found no issues with platinum-cured silicone and water washable resin. Standard resins and tin-cured silicone work well, but the silicone may experience some long-term shrinkage.
