Resin Keycaps

Update: My process has improved, see newer keycaps here

I recently started casting keycaps as a quarantine hobby.

I’m making one a day.


I’m pleasantly surprised the quality of the mold registration. It captured the matte texture on the tops of the keys while keeping the sides smooth and shiny.

I’m using a two-part silicone mold made with L2K adapters. Since my keyboard has DCS sculpted keys (every row of keys is shaped differently), I’ll need to make a mold per row.


The keycaps are susceptible to giant air bubbles. I’m taping the mold to release trapped air but I might purchase a pressure pot in the future.


Once I master the fundamentals, I’ll attempt to make embeded keys like Jelly Key.
