Abstract
An additive manufacturing system is described that provides centrifuge-based additive object manufacturing includes a drum containing a working material that solidifies after being irradiated by a light source, the working material spreads evenly over an item being manufactured when the drum is in motion. A light source module emitting a light capable of solidifying the working material includes multiple light sources that travel upward and downward within the drum in vertically offset helical patterns to efficiently solidify the working material.
Claims20
An additive manufacturing system, comprising:
- a drum having an interior-facing curved surface;
- a light source module comprising a plurality of light sources;
- and
- a processor configured to execute computer code that when executed causes the additive manufacturing system to:
- rotate the drum;
- apply a first layer of working material to the interior-facing curved surface;
- move the light source module disposed at least partially within the drum toward a base of the drum such that the plurality of light sources follow a first plurality of scanlines across the first layer of the working material in a first helical pattern;
- apply a second layer of working material to the interior-facing curved surface atop the first layer of working material;
- and
- move the light source module away from the base of the drum such that the plurality of light sources of the light source module follow a second plurality of parallel scanlines across the second layer of material in a second helical pattern,
- wherein the light source module moves at a speed such that actuation of a light source of the plurality of light sources over a first region of the working material during two consecutive rotations of the drum results in unsolidified material being left between a first portion of the first region solidified by the light source during a first one of the consecutive rotations and second portion of the first region solidified by the light source during a second one of the consecutive rotations.

A method, comprising:
- rotating a drum of an additive manufacturing system;
- applying a first layer of working material to an interior-facing curved surface of the drum;
- moving a light source module disposed at least partially within the drum toward a base of the drum such that a plurality of light sources of the light source module trace a first plurality of scanlines across the working material on the interior-facing curved surface of the drum in a first helical pattern;
- applying a second layer of working material to the interior-facing curved surface of the drum;
- and
- moving the light source module away from the base of the drum such that the plurality of light sources of the light source module trace a second plurality of parallel scanlines across the second layer of working material on the interior-facing curved surface of the drum in a second helical pattern,
- wherein the light source module moves at a speed such that actuation of a light source of the plurality of light sources over a first region of the working material during two consecutive rotations of the drum results in unsolidified material being left between a first portion of the first region solidified by light source during a first one of the consecutive rotations and second portion of the first region solidified by the light source during a second one of the consecutive rotations.
