  • 3D printing is a process of fabrication of digitally designed three-dimensional objects.
  • Printing in the Fused Filament Fabrication technology is effected by means of depositing consecutive layers into a predetermined shape.
  • the technology consists in delivering a synthetic thermoplastic materia! strand heated to a semi-liquid state to the print head for three-dimensional printing, moving spatially in three dimensions.
  • the thermoplastic materials (half-products in 3D printing) used for printing in this technology can be any kind of thermoplastic synthetic material in the form of a strand wound upon a spool, hereinafter referred to as the filament.
