There are many different types of printers, such as Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), Selective Laser Melting (SLM), Digital Light Processing (DLP), Electronic Beam Melting (EBM), Laminated Object Manufacturing (LOM), Binder Jetting (BJ)... Each printer type employs different materials. The Prototype Lab has FDM and SLA machines.
