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.
