Fused deposition modeling (FDM)

Fused deposition modeling (FDM)

How to print 3D by using Fused Deposition Modeling? First, as a member of the nordic and almost literate nation Sweden, I had to use a dictionary to the word ”fused”. Logically (and just as I thought *cough!*) the word means ”melted”. Melting is just happens when printing 3D with FDM. Och plastic (or metal) wire melts through an extrusion nozzle (just like when making writing on a birthday cake) and gets added to the real 3D object layer by layer. The FDM method is very direct and has been around since 1980 (maybe because its simple nature?). Some manufacturers of FDM 3D printing machines says that almost any material can be used in these machines as long as it’s easily melted and stays stiff after application. Constructions of chocolate has been made! In industry however, the most commonly used materials are thermoplastics and eutectic metals.
