SLS is similar to stereolithography, except that the process involves lasers and powders instead of UV light beams and liquid. This allows for a higher quality printout. Stereolithography also uses the additive process but instead of extruding plastics, the process utilizes an ultraviolet light beam to harden a model from a pool of photosensitive liquid. They are much more expensive compared to FDM. There are 2 other types of 3D printing available: Stereolithography and Selective Laser Sintering (SLS). Most of the 3D printers referred in this post works on FDM, as they are more widely available and easy to find. Fused Deposition Modeling (FDM)įDM is an additive process, where a model is created by heating and extruding plastic, pieced together layer by layer. The one you probably heard of in the media and the most popular among hobbyists is the one that uses Fused Deposition Modeling (FDM). Types of 3D printersģD printing is a broad term that covers the technologies required for producing physical materials. There was a time when 3D printers were a novelty - but not anymore. 10 Cheap and Affordable 3D Printers to Buy
