Appl. No.:

16/270724

Inventors:

- Somerville MA, US
Yoav Reches - Cambridge MA, US
Jason Livingston - Somerville MA, US
Jeffery Morin - Boston MA, US
Caitlin Reyda - Cambridge MA, US

Assignee:

Formlabs, Inc. - Somerville MA

International Classification:

B33Y 30/00
B29C 64/20
B29C 64/135
B33Y 10/00
B29C 64/10

Abstract:

According to some aspects, a method of additive fabrication wherein a plurality of layers of material are formed is provided. The method may comprise forming a layer of material in contact with a container, and subsequent to the forming of the layer of material, actively bending the container around at least one fixed point such that the layer of material separates from the container. According to some aspects, an additive fabrication apparatus configured to form a plurality of layers of material is provided. The apparatus may comprise a container, a build platform, one or more force generators, and at least one controller configured to, subsequent to formation of a layer of material in contact with the container, actively bend the container around at least one fixed point via the one or more force generators, such that the layer of material separates from the container.

International Classification:

G03F 7/20

US Classification:

355 72

Abstract:

3D printing systems and methods avoid build-compromising misalignments through the use of a self-leveling assembly that maintains a constant and typically fully parallel orientation between a build platform and the bottom surface of a resin tank. As a result, contact between the floor of the resin tank and the build platform surface may be uniformly flat and even, and perpendicular to the z-axis motion of the deposition source.
