Abstract
In one embodiment, an additive manufacturing method including the steps of positioning a removable surface on a worktable; applying an adhesive material to the removable surface; depositing a plurality of pellets into the adhesive material, wherein at least a portion of each pellet of the plurality of pellets remains exposed; depositing a first plurality of layers of a flowable material on at least some of the plurality of pellets; and depositing a second plurality of layers of the flowable material on the first plurality of layers.
Claims22
An additive manufacturing method, the method comprising:
- positioning a removable surface on a worktable;
- applying an adhesive material to the removable surface;
- depositing a plurality of pellets into the adhesive material, wherein at least a portion of each pellet of the plurality of pellets remains exposed;
- depositing a first plurality of layers of a flowable material on at least some of the plurality of pellets;
- and
- depositing a second plurality of layers of the flowable material on the first plurality of layers.
16-20. (canceled)
An additive manufacturing system, comprising:
- a programmable computer numeric control (CNC) machine configured to extrude a flowable material, wherein the programmable CNC machine includes a worktable;
- and a removable surface positioned on the worktable, wherein the removable surface includes an adhesive material thereon, a plurality of pellets, wherein at least a portion of each pellet is embedded in the adhesive material and at least a portion of each pellet remains exposed, and a first plurality of layers of the flowable material deposited on at least some of the plurality of pellets.
