Title:
BUILDING LAYERS WITH UNSUPPORTED PORTIONS THROUGH SELECTIVE DEPOSITION-BASED ADDITIVE MANUFACTURING
Document Type and Number:
WIPO Patent Application WO/2019/133846
Kind Code:
A3
Abstract:
A method of selective deposition-based additive manufacturing includes conveying a layer (28) of material to previously built layers (22) of material. A determination is made as to whether at least one of the conveyed layers (28) of material and a top previously built layer (22) of material contains an unsupported portion (302). When at least one of the conveyed layer (28) of material and the top previously built layer (22) of material contains an unsupported portion, a first set of steps (306, 408, 506) are used to transfer the conveyed layer (28) of material to the top previously built layer (22) of material. When neither of the conveyed layer (28) of material and the top previously built layer (22) of material contains an unsupported portion, a second set of steps (304, 406, 504) are used to transfer the conveyed layer (28) of material to the top previously built layer (22) of material.
