INDEPENDENT FABRICATION OF OBJECTS AND OBJECT SUPPORTS

Номер: US20190060997A1

Автор: CHIANG Yet-Ming, Chin Ricardo, Fontana Richard Remo, FULOP Ricardo, Gibson Michael Andrew, Hart Anastasios John, MYERBERG Jonah Samuel, Schuh Christopher Allan, Verminski Matthew David

Принадлежит:

Additive fabrication systems generally use support structures to expand the available range of features and geometries in fabricated objects. For example, when a vertical shelf or cantilever extends from an object, a supplemental support structure may be required to provide a surface for fabrication thereon. This process may become more difficult when, e.g., a part will be subjected to downstream processing steps such as debinding or sintering that impose different design rules. To address these challenges and provide a greater range of flexibility and processing speed, it may be useful in certain circumstances to independently fabricate the object and support structures, and then assemble these structures into a composite item for debinding and sintering. This approach also advantageously facilitates various techniques for spraying, dipping, or otherwise applying a release layer between the support structure and the part so that these separate items do not become fused together during sintering. 1. A method comprising:fabricating a support structure for an object from a first material;fabricating the object from a second material, the object including a surface positionable adjacent to and supportable by the support structure, wherein the second material includes powdered material for forming a final part and a binder system including one or more binders, wherein the one or more binders resist deformation of a net shape of the object during processing of the object into the final part;applying an interface layer to a least one of the support structure and object at a location corresponding to the surface of the object positionable adjacent to and supportable by the support structure, wherein the interface layer resists bonding of the support structure to the object during sintering; andassembling the support structure and the object together with the surface positioned adjacent to and supported by the support structure, thereby providing an assembled workpiece.2. ...

A method of generating a mold and using it for printing a three-dimensional object

Номер: US20210069784A1

Автор: Alexander C. BARBATI, Mats Moosberg

Принадлежит: Addleap AB, Desktop Metal Inc

This invention relates to three-dimensional printing. This invention in particular relates to a method of generating mold and printing a three-dimensional object. The mold thickness is controlled and holes are generated in the mold surface for releasing moisture easily. The mold surface having holes is designed initially digitally and then combined with the three-dimensional model before printing the three-dimensional object. In case the thickness of the mold surface is more then it reduces the overall quality of the three-dimensional object. When the model is enclosed inside the mold, there will be some residue moisture in the model even if the drying apparatus can improve this by drying layer by layer. This affects the final quality of the part. A solution of these problems is provided in the present invention. The thickness of the mold layer is between 0.5 to 1 mm and holes having 0.1 to 0.4 mm diameter. The holes are evenly distributed on the mold. The mold having the holes is prepared from which moisture can easily escape. A method of digitally generated a mold having thin layer and holes is used for fabricating three dimensional objects with high precision and quality.
