A resin artisan keycap begins long before any resin goes into a mold. In a short start-to-finish video, a maker builds a second version of a character cap, moving from a digital sculpt to a test casting. The useful part is seeing how many small decisions sit between an appealing design and a cap that can actually be reproduced.

## Start with a master that can survive scrutiny

The maker sculpts the character digitally, then 3D-prints a master. Clay would also be possible, but the digital route makes it easier to revise the shape before committing to a mold. After printing, the master is washed and fully cured. That step matters: the mold will copy defects as faithfully as it copies good details.

## The mold is where detail can disappear

The printed master goes into a container for a silicone pour. The maker first works a little silicone into the fine details, then pours the rest slowly. Air caught around a small feature can leave a missing section in every cast that follows. In the video, the mold cures in a pressure pot; once opened, the maker checks that it has captured the sculpt cleanly.

## Cast, inspect, then try color

For the first resin casting, the maker rotates a small amount of resin around the mold to reach its details, pre-fills the stem section and joins the mold halves before another pressure cure. The result is a test cap, not yet the planned multicolor version. Removing it and inspecting the surface helps reveal whether the master or mold needs another pass.

That sequence is a helpful reminder for anyone ordering a small artisan run. Ask to see a physical sample from the actual mold, including the stem and hard-to-fill details, before judging a render. A successful first cast proves the process is working; color layering, consistency and fit still need their own checks.
