Making Photopolymer Stamps: Materials List & Pictorial

So you want to start making photopolymer stamps? I’ve been posting pictures to social media about making stamps and some have asked how it’s done. I’m no expert, but over the past few weeks of trial and error along with a lot of research, I’ve been able to put together a pretty decent work flow.

Let’s start with what you’ll need. I’ve tried to include everything I use and included amazon, web links and stores where you can find these items.

For the stamp I’ll be making in this post, I used my drawing of a pumpkin and you can download it __here__ if you’d like to follow along with it.

Making my mother some stamps with COLOP Photopolymer

My mother, after seeing my doodles and watercolor  post, suggested that I try making stamps, which sounded fun.   I had most of the equipment from other projects to give it a go.  All I really needed was the photopolymer.   After ordering a bottle of COLOP photopolymer off amazon, it showed up a few days later (it wasn’t even amazon prime, so I was impressed).

My first idea was to shove it into my 3D printer.  The whole idea behind my new printer was that it uses UV Resin, which is what a photopolymer is.   Shine a UV light on it and it cures.   It turns out that this stamping resin is so highly viscous that it’s barely a liquid and 3D printer resin is still quite liquid.   I started pouring it into the printer and it was hard to stop it from pouring because it was pulling itself out of the bottle.

Well, I can tell you that didn’t go well.   It was far too thick and the printer didn’t like it.  After editing the 3D printer’s program to see if I could make it work, I found the cured photopolymer wasn’t sticking to the platform and just ended up making a mess.
