Strong, reliable parts with SLA

SLA is one of the first 3D printing technologies, known for creating complex, durable parts. The method uses a layer by layer building process to create a solid part. SLA is ideal for general-use prototypes and short-run production.

The process of SLA technology was the foundation of many other 3D printing technologies. The printer contains a tank for material, a build platform, a laser source along with a UV light to cure the material. Following a CAD file, the material is traced by the laser source and the UV light immediately cures said material to create the first layer. The platform rises as each layer is printed. Once the part is finished, the remaining resin is drained out, leaving a final part.

SLA is an excellent option for a wide variety of industries and applications. The technology is great when building product models, general use prototypes and finished parts. SLA can enable prototyping and production for industries including medicine, aerospace, architecture and more.

Benefits of SLA

  • Prototyping and full-scale production
  • Durable, reliable parts
  • High resolution, accurate parts
  • Smooth, aesthetic surfaces
  • High-quality models
  • Time savings and speed to market
