Diy resin is very simple to make and can be done at home. The hardest part would probably be sourcing the chemicals cheaply.

You need a monomer (the resin) and a photo-initiator (plus dye if you want it coloured.)

Put the monomer into a container (not opaque!) and put it on a magnetic stirrer at low speeds.
Add the dye and leave for a small duration.
Then add the photo-initiator and let it stir until there is no hard substances (probably 3-5 days.)

Once done it's ready to be used, or stored away.

You'll obviously want to play with the speeds and duration and it will change with how much resin you're trying to make at a time.


This is the standard recipe people talk about:

Monomer: 1000 ml 1,6-Hexanediol diacrylate
Dye: 0,06 g Sudan I
Initiator: 20 g Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide

There's plenty of different chemicals you can use however. Some initiators work better than others for certain frequencies.

You also have to purchase in good quantities to get a good price however.
