Siraya Tech Build (Grey)

This is the resin most of the minis are printed with. If you bought a 3D-printed mini from me, it almost certainly started life as this stuff on my printer. I figured I’d dump all the paperwork in one spot so you don’t have to take my word for any of it.

What it is

Siraya Tech Build in grey. It’s a tough UV resin made for resin printers, the kind that doesn’t shatter the second you look at it funny. I print every part, wash it, and cure it under UV before it goes anywhere near a box. Once it’s cured it’s just a hard, stable hunk of plastic. The stuff you have to be careful with is the liquid resin before it cures, and that’s my problem down in the basement, not yours, because by the time your mini shows up it’s already cured and cleaned.

Why I keep all this paperwork

Look, I’m one guy printing in my basement. That doesn’t mean I’m winging it. I’d want to know what a thing was made of before I handed it to my kid or started sanding it at my desk, so I hang onto the manufacturer’s safety and compliance docs and stick them right here. If you ever need them, for your own peace of mind or because some club or school asked, they’re sitting below.

The docs

• Safety Data Sheet (the SDS). The big one. Hazards, handling, first aid, disposal, all of it, for the liquid resin. This is the one most people mean when they ask for an MSDS.
• Technical Data Sheet (TDS). The nerdy one. Mechanical properties and cure settings, mostly handy if you print too.
• RoHS certificate. Says it’s clear of the restricted heavy metal nasties like lead, mercury, and cadmium.
• REACH certificate. The European chemical safety declaration saying there’s no restricted bad stuff in it.

All PDFs, straight from Siraya Tech. I didn’t write these, I just keep them handy.

Is it safe to handle?

Yeah. Your cured mini is fine to hold, paint, and stick on a shelf. Cured resin is inert, it just sits there being plastic. The scary-sounding warnings in the SDS are about the liquid resin and the fine dust you’d kick up sanding or drilling it, and that’s the part I deal with on my end. If you do a ton of sanding or cutting or drilling on your minis though, it’s worth doing it the smart way. I wrote the whole thing up here:
