FDM, or Fused Deposition Modeling, is a 3D printing technique that has successfully transitioned from the commercial to consumer 3D printing space. Most home FDM 3D printers can melt and extrude a wide variety of thermoplastic polymers into functional and cosmetic parts. However, a vast majority of 3D printing enthusiasts swear by PLA and ABS polymers, which are sold in convenient filament spools.
