Acrylic blanks technique

You might try asking Lucite:

could make casting resin and make anything you want. Would require good temperature control and fume venting. Lucite sells methyl methacrylate monomer and Elvacite grades of polymer where I think all you have to do is mix resin with monomer and heat up under conditions where bubbles do not nucleate.

Frank, there is an acrylic liquid and hardener that can be used to embed objects. No additional heating is needed. I wonder how it works without the need for heat? Just slower perhaps?

There are low temperature catalysts but mass will heat up with heat of polymerization. The system I recommended is probably relatively inexpensive. The resin advised contains residual catalyst which when mixed with MMA allows cure. Use of the resin, already polymerized, results in less need for removing heat of polymerization.

There are numerous acrylic repair kits containing monomer and catalyst but would probably be too expensive to cast large parts. They will cure at low temperature since mass is small and heat of polymerization easily dissipated.
