PC-Equivalent Plastic

PC-Equivalent Plastic

PC-Equivalent Plastic material is a photo-cured resin. It simulates properties and appearance of polycarbonate material. It has a good ability to resist humidity and maintain dimensional accuracy.

PC-Equivalent Plastic is a translucent (60-70% transparency) material. It is suitable for applications that require ‘clear’ parts that need finished, production look. Since parts are fabricated using Stereolithography (SLA) technology, there is support structure generation during fabrication. Despite support structures, PC-Equivalent Plastic comes with a smooth surface finish, and little burs (if any) left during the support structure removal can be polished to give the part a superior surface finish.

Material data

PC-Equivalent Plastic is a polycarbonate-like material that comes with a smooth surface finish and a translucent, clear color. It is mainly used in automotive designing and styling components.

PC-Equivalent Plastic Design Guidelines

Wall thickness

  • For a given part geometry, the minimum wall thickness should be at least 1mm.
  • For decent strength: 1.5mm.
  • For rigid wall: 2mm.

Minimum detail size

  • The minimum supported feature thickness: At least 0.5 mm.

Support Structures

  • Since PC-Equivalent Plastic parts are fabricated in Stereolithography (SLA) technology, support structures are generated on part geometries with overhangs and unsupported features.

Embossing and Engraving:

  • Recommended fonts for a clear, legible text: Arial, Gothic
  • Letter strand width: at least 0.5mm
  • Embossing height: at least 0.5mm
  • Engraving (cavity) depth: at least 0.5mm


  • If the length of the wall is greater than 50mm (5 cm), then a minimum wall thickness of 2mm should be kept to impart decent strength.
