The heating process is carefully regulated by a The raw material for printing comes from a plastic rod (yellow, 46), melted by the print head. Head and nozzle (2 and 4, orange) move in the vertical (Z) direction. On a baseplate (dark blue, 10) that moves in the horizontal (X–Y) directions, while the print In this design, the model (pink, 40) is printed Their own rapid prototypes, in hours, using sophisticated machinesĪrtwork: One of the world's first three-dimensional FDM printers,ĭeveloped by S.
