US 2021/0268735 A1 · HEAD, DEPOSITION ARRANGEMENT, AND METHODS FOR CONTROLLING A HEAD

Abstract

The present invention relates to a head (100) of a deposition arrangement (600) used to fabricate three-dimensional objects. The head (100) includes a casing (110) with a first end (112) including an end opening (114) arranged to be positioned on a surface (210a, 210b, . . . , 210n). The head (100) further includes a material receiving arrangement (115) arranged to receive a granular material (125) into the casing (110) and onto the surface (210a, 210b, . . . , 210n). A piston (130) is arranged to move inside the casing (110) towards the first end (112) such that the piston (130) presses the granular material (125) against the surface (210a, 210b, . . . , 210n) and the granular material (125) thereby forms a deposition volume V. The invention further relates to the deposition arrangement (600) including the head (100) and corresponding methods.

Dependent claims

Head of a deposition arrangement arranged to create layers of deposition volumes, the head including:

a casing including at least three wall segments defining a deposition area A and extending from a first end to a second end of said casing, said first end of said casing including an end opening arranged to be positioned on a surface;
and
at least one material receiving arrangement arranged to receive a granular material into said casing and onto said surface;
further comprising:
a piston arranged to be movable inside of the casing, towards said first end and towards said second end, such that said piston presses said granular material against said surface when said piston is moved towards said first end, said granular material thereby forming a deposition volume V.
