Title:
METHODS AND APPARATUS FOR SELECTIVELY COMBINING PARTICULATE MATERIAL
Document Type and Number:
Japanese Patent JP2019001171
Kind Code:
A
Abstract:
To provide an alternative method of selectively combining a particulate material.SOLUTION: A method comprises: a step of providing a layer of particulate material on a surface of a partial base using a deposition device; a step of sintering a portion of the layer by supplying radiation; a step of providing an upper layer additional layer onto an upper layer of the previously provided layer by using a deposition device; a step of sintering another portion in the upper additional layer by supplying radiation to sinter the another portion to the previously sintered portion of the previously provided layer; and a step of continuously repeating the third and fourth steps to shape a three-dimensional object. One or more layers are preheated before and independently of sintering a part of the material of each layer by a radiation heater. The radiation heater is arranged by separating from a particulate material deposition device, and is configured so as to traverse over a surface of the partial base following the particulate material deposition device to transfer heat to the deposited particulate material via radiation.SELECTED DRAWING: Figure 9
