Process of support removal for fused deposition modeling |
摘要 |
Processes and apparatus are disclosed for producing three-dimensional objects having overhanging portions freely suspended in space without any material of the object in direct, supporting engagement therewith in the final geometry of the object. A support structure is formed by depositing material which will be under the ultimately suspended portions of the object to be formed, during a process in which material is built up in layers to form the object as well as the underlying support structure. A readily removable support structure is formed along an interface with the underside of the suspended portion of the object structure. A weak, removable or breakable joint is formed along that interface by the use of an interface material which forms a weak or dissolvable bond with the material of the object. The release material may be deposited as a separation layer, or as a thin coating.
