SLA 3D Printing Service

Stereolithography is a 3D printing process that produces parts with a very smooth raw surface.

What is SLA 3D printing?

SLA printing works by solidifying a liquid polymer into the desired form with a special laser. This process is repeated in layers until the part is complete. 

Stereolithography is often used to replace traditional injection molding processes, because it creates a very similar part with less time and trouble.

Today, SLA processes are being refined and scaled to fit in different industries and sectors.

Post-processing for SLA

The only post-processing finishing option available for SLA parts is raw. This is because a raw finish with the SLA process is already very smooth and should be acceptable for most projects. We also cannot dye any SLA parts.

Advantages and drawbacks of SLA 3D printing


  • Structurally reinforced parts
  • Highly precise geometries
  • Substitute for inject molding


  • Limited color options
  • More expensive than nylon printing
  • Less suited to mechanically functioning parts

Designing files for SLA printing

When designing CAD files for SLA printing, it is important to remember some requirements for successful designs.

1. Add external support posts that will be needed during printing and can be removed in post-processing

2. Ensure sufficient wall thickness and space between features to minimize warping

3.  Text or embossed details should be at least 0.1mm above surface
