High Gloss |
Surface finish with high reflectivity is produced by polishing the original pattern prior to making the mold. This glossy finish provides excellent translucency for parts intended for beauty, optics, and easily cleaned surfaces. |
A1, A2, A3 |

Semi Gloss |
This B level finish does not reflect light much but does provide a bit of shine. By employing coarse sandpaper, you can achieve smooth, washable surfaces that fall between glossy and flat. |
B1, B2, B3 |

Matte Finish |
Cast parts from a vacuum will acquire a satin-like texture via bead or sand blasting of the original model. The C-quality finishes are perfect for components that are often touched and handheld. |
C1, C2, C3 |
