A Few Different Types of Additive Manufacturing, or 3D Printing, Include:
SLA – Stereolithic
SLA uses UV laser technology to cure sequential layers of photopolymer resin. SLA is popular due to its high resolution and detail, fast build times, and durable substrates.
FDM – Fused Deposition Modeling
FDM “prints” melted thermoplastic materials through a nozzle. The previous layer begins to harden before the next layer is laid down. This method is popular for rapid prototyping. Support structures are often “printed” to stabilize the form as it is built.
PBF – Powder Bed Fusion
PBF uses lasers, electron beams or thermal print heads to melt (or soften) and fuse ultra-fine layers of powdered material. This method can be used to build electrical circuits and well as mechanical parts.
Direct Energy Deposition
A material extrusion process in which a laser or electron beam melts wire, filament or powder. Can be used to repair or add to existing objects.
