Abstract

The invention discloses a sheet-based adhesive manufacturing method and a system. A method of fabricating a part includes stacking sheets of fusible material to form a stack. The method also includesdirecting a laser beam through at least one sheet of the stack. The method also includes transferring energy from the laser beam to multiple locations on at least one interface between adjacent sheetsof the stack, according to a predetermined pattern corresponding with a design of the part, to form corresponding multiple molten regions. The molten regions are conjoined together to form a fused portion of the adjacent sheets. The fused portion of the adjacent sheets defines the part.

Description

technical field [0001] The present disclosure relates generally to additive manufacturing, and more particularly to additive manufacturing using sheet material as an additive material. Background technique [0002] Conventional additive manufacturing techniques use powder or wire-fed materials to produce parts. However, producing parts in a time-, cost- and energy-efficient manner using conventional additive manufacturing techniques can be difficult. Furthermore, parts produced by conventional additive manufacturing techniques have poor surface finish and often require the use of support structures, especially for parts with complex geometries. Contents of the invention [0003] The subject matter of the present application has been developed in response to the current state of the art, and in particular, in response to the shortcomings of additive manufacturing that have not yet been fully addressed by currently available technologies. Accordingly, the subject matter of...
