Stereolithography 3D printing produces high accuracy and isotropic prototypes and parts in a range of materials.

SLA 3D PRINTING PROVIDES:

  • Fine features and smooth surface finish
  • Detailed, watertight prototypes and parts
  • Selection of resins that replicate thermoplastic-like materials
  • Fast turnaround for small part production
How Stereolithography Works

Stereolithography belongs to the category of vat photopolymerizaton additive manufacturing, commonly know as resin 3D printing. SLA  uses a UV laser directed by a software-controlled mirror to cure photopolymer liquid resin layer-by-layer to form 3D objects. Parts are built upside-down and the build platform rises out of the liquid resin reservoir as layers are constructed. When viewed as a time lapse, parts appear to grow out of the resin bath. After completion of the printing process, the part is removed from the platform, washed of excess resin, and then placed in a UV oven for final curing. Any resin untouched by the laser remains in the reservoir and can be reused. Post-print curing enables parts to attain the highest possible strength and become more stable.

With a range of advanced materials, our SLA 3D printing services supply the fine features and precision necessary for applications like jigs and fixtures, end-use parts, and robust functional prototypes.
