MJF works by rolling a thin layer of nylon beads across the build surface. Next a printhead releases agents over the nylon surface defining geometry to be fused by the fusing lamp.
MJF is the most advanced form of polymer 3D printing commercially available to date. Layer resolution combined with nylon's durability creates the perfect mix for final product prints. MJF has officially brought 3D printing to the level of final production.
A Stereolithography apparatus works by curing a photopolymer resin with a laser building the part upside down layer by layer.
SLA is best suitable for individuals / companies looking to make very high quality prototypes with a glass like finish and no visible layer lines.
Fused Deposition Modeling works by melting and extruding thermoplastic filament to build a part up a layer at a time.
FDM is best suitable for those looking to make very low cost prototypes / models, where visible layer lines will not have an effect.
