    The SLA process’ high accuracy, a large variety of material selections, smooth surface finish, and a wide variety of post-processing options making it the perfect choice for a wide range of rapid manufacturing applications, including concept models, rapid prototypes, master patterns, snap-fit assemblies, and form-and-fit testing.

    Whether you are looking for small, intricate electronic connectors or large volume instrument panels for your next concept vehicle, SLA parts can fulfill application needs for transparency, high-temperature, high stiffness or other qualities and functions.

    Highlights:
    * 3D Systems  Founder and CTO, Chuck Hull, invented SLA in 1983
    • Wide range of 3D Systems SLA printers, materials and software
    • SLA can produce very large parts (up to 1.5m in one piece)

  • A row of 3D Printers in a facility

    3D Systems On Demand has deep expertise and capabilities with Stereolithography (SLA) technology as our founder, Chuck Hull, invented the technology in 1983.

About this process

Overview

Stereolithography (SLA) utilizes a vat of liquid photopolymer resin cured by an Ultra Violet (UV) laser to solidify the pattern layer by layer to create a solid 3D model from customer supplied 3D data. The SLA process addresses the widest range of rapid manufacturing applications.

Attributes:

  • High accuracy
  • Large variety of material selections
  • Smooth surface finish
  • Wide variety of post processing options

Tolerances for standard resolution:

  • X/Y planes: +/-.005” for the first inch, plus +/-.002” for every inch thereafter
  • Z plane: +/-.010” for the first inch, plus +/-.002” for every inch thereafter
  • Minimum linear feature size: under .030” are at risk and under .020” will not build
  • Minimum radial feature size: .035"

Tolerances for high resolution:

  • X/Y planes: +/-.005” for the first inch, plus +/-.002” for every inch thereafter
  • Z plane: +/-.010” for the first inch, plus +/-.002” for every inch thereafter
  • Minimum linear feature size: under .020” are at risk and under .010” will not build
  • Minimum radial feature size: .030"3D Systems’ SLA printers are able to print highly detailed parts ranging from just a few millimeters in size, all the way up to 1.5 meters (5 ft), with exceptional resolution and accuracy and virtually no part shrinkage or warping.
Applications

The SLA process’ high accuracy, large variety of material selections, smooth surface finish, and wide variety of post processing options make it the perfect choice for a wide range of rapid manufacturing applications.
