SLA Stereolithography from Advanced Prototyping

SLA for the Ultimate in Accuracy and Cost Effectiveness

Stereolithography (SLA) is a "rapid prototyping" process which produces a physical, 3D model from a 3D CAD file. Our advanced SLA 3D printers produce exact plastic and composite material parts without the restrictions of CNC or plastic injection molding. With accuracy and surface quality of this level, you can produce low- to medium-run parts at a lower per-unit cost and build massive, highly detailed pieces faster. How fast? SLA prototypes can be made in a matter of hours.


Typically used for design verification, some SLA models are used to check form, fit and function, other models are used as a master to create a silicone mold to inject urethane into, to make duplicates.

SLA 3D Printing Features:

  • Reduces per-unit costs on low- to medium-sized runs.
  • Matches your exact mechanical and optical specifications with the broadest range of materials available.
  • Cuts finishing time and enjoy the best surface quality available from any 3D printing.
  • Identifies design flaws early with true-to-design accuracy and surface finish.
  • Produces large, whole parts and cut both the time required for assembly and part weakness associated with attachment points.
  • Streams the path from CAD or scan to final prototype part production.

There are several SLA materials to choose from. Click on the Product Data Sheets below for material specifications

SLA/Flexible - DSM-9120 Amber/Milky

Robust, accurate epoxy resin for stereolithography. SLA parts created with Somos® 9120 exhibit superior fatigue properties, strong memory retention, and high quality up-facing and down-facing surfaces.

SLA/Rigid - DSM-10122 Clear

DSM Somos® WaterClear Ultra 10122 is a next generation optically clear resin with ABS like properties and good temperature resistance. In SLA rapid prototyping, it produces colorless, functional, accurate parts that simulate acrylic in appearance. Based on the Oxetane Advantage™, the parts also have improved water resistance over the original WaterClear 10120 resin. WaterClear Ultra is a fast, low viscosity, general-purpose resin.
