Types of 3D Printing

There are several types of 3D printing, which include:
  • Stereolithography (SLA) uses UV lasers as a light source to selectively cure a polymer resin.
  • Digital light processing (DLP) uses a digital projector as a UV light source to cure a layer of resin.
  • Liquid crystal display (LCD) uses an LCD display module for projecting specific light patterns.
  • Selective laser sintering (SLS) melts together nylon-based powders into solid plastic.
  • PolyJet is another plastic 3D printing process, but there’s a twist.
  • Digital light processing is similar to SLA in that it cures liquid resin using light.
  • Similar to SLS, Multi Jet Fusion also builds functional parts from nylon powder.
  • Fused deposition modeling (FDM) is a common desktop 3D printing technology for plastic parts.
