Abstract
According to one embodiment, a material feeding device includes a feeding unit. The feeding unit includes an electrode unit electrically chargeable by application of voltage thereto and an insulating unit covering the electrode unit, the electrode unit being configured to attract and separate a material to and from a surface of the insulating unit by control of a charged state of the electrode unit.
Claims10
An additive manufacturing apparatus comprising:
- a housing configured to store a material;
- an electrode feeder comprising an electrode which is electrically chargeable and an insulator covering the electrode, the electrode being configured to attract and separate the material to and from a surface of the insulator based on a charged state of the electrode;
- a region configured to be fed with the material;
- an electrode feeder driver configured to change a relative position between the electrode feeder and the region;
- a laser oscillator configured to emit a laser light;
- an optical element configured to apply the laser light on a predetermined position of the region;
- and
- a controller configured to determine the predetermined position based on cross-sectional shape data generated from three-dimensional data of a manufactured object, wherein
- the region is grounded such that the material fed onto the region exhibits zero charge.
