What It Is

Welcome to our smoothest process.

SLA prints by curing liquid resin with light, one ultra-fine layer at a time, which gives your part the smoothest surface and the sharpest detail. It is ideal for small, high-detail production parts, molds, and parts that have to look perfect. Every part is washed, cured, and finished by hand before it ships.

Finest Detail, Smoothest Surface

Layers thinner than a human hair, with a finish that needs almost no work:

  • Tiny features & text: micro details and legible lettering, held crisp and clean.
  • Thin walls & fine lattices: open, fine-walled structures that stay true.
  • Glassy, paint-ready surface: layer lines you have to look hard to find, ready to prime and paint.

Clear & Color

Parts you can see through, or printed in the color you need:

  • Clear parts & molds: see-through housings, lenses, and molds that show the cavity as you cast.
  • Printed in color: black, white, grey, or clear resin, with no paint needed.
  • Painted any color: matched to your spec, sprayed to a flawless finish.

Build In Your Branding

Your identity, printed into the part:

  • Logos & fine text: raised or recessed, down to the finest edge and smallest number.
  • Branded products: merch, packaging, and demo pieces with your brand built in.
  • Surface patterns: textures worked into the surface itself.
