FDM - Fused Deposition Molding
FDM works on an "additive" principle by laying down material in layers.
The model is produced by extruding small beads of thermoplastic material to form layers as the material hardens immediately after extrusion from the nozzle.
The nozzle can be moved in both horizontal and vertical directions by a numerically controlled mechanism
type of thermoplastic. It should not be confused with the related polymer polyvinyl alcohol, which is called PVA also (PVAc could be considered a technically correct abbreviation for polyvinyl acetate and would aid in avoiding such confusion). Polyvinyl acetate is a component of a widely-used type of glue, referred to variously as wood glue, white glue, carpenter's glue, school glue or PVA glue.
