Method and assembly for additive manufacturing

摘要

An additive manufacturing method (1600) may involve additive manufacturing (1602) a walled structure (e.g., a shell or an enclosure) onto a print bed, positioning (1604) a support piece having a non-stick surface (e.g., a Teflon®) near or inside the structure, additive manufacturing (1606) a layer of material onto one or more walls and onto the support piece to create an overhang, and removing (1616) the support piece after the material making up the overhang has returned to a solid state or hardened.

主权项

1. A method comprising:
additive manufacturing a first wall and a second wall that meet at an angle to form a first corner of a shell; positioning a first support piece proximal to the first wall and the second wall and within the interior of the angle; additive manufacturing a first overhang that extends from the first wall and the second wall onto the first support piece, the first overhang forming at least a portion of a first face of the shell, wherein the first support piece is freestanding with respect to the first wall and the second wall; positioning the shell such that the first face contacts a print bed and a second face of the shell faces up; positioning a second support piece within a portion of the shell that was repositioned; and additive manufacturing a second overhang that extends from the first wall or the second wall onto the second support piece.
