Abstract
A build plate is configured for use in a 3D printer. The build plate comprises a base comprising a base material and one or more vacuum channels. A removable plate is disposed proximate the base so as to be in fluid communication with the vacuum channels.
Claims22
A build plate configured for use in a 3D printer, the build plate comprising:
- a base;
- a porous layer positioned on the base;
- and a removable plate, wherein the removable plate comprises a sacrificial layer, wherein the sacrificial layer comprises one or more protuberances that are integral with the sacrificial layer, wherein the protuberances extend through an entire dimension of the base, and etch stop layer positioned on the sacrificial layer, wherein the etch stop layer is thinner than the sacrificial layer, wherein the etch stop layer has a thickness from about 0.1% to about 10% of a total thickness of the removable plate, wherein the sacrificial layer has a thickness from about 90% to about 99.9% of the removable plate.
A three-dimensional (3D) printer, comprising:
- a printhead;
- a stage disposed proximal the printhead, the stage comprising a build plate, the build plate comprising:
- a base comprising a base material and defining one or more vacuum channels therethrough;
- a porous layer positioned on the base;
- and a removable plate positioned on the porous layer, wherein the removable plate comprises a sacrificial layer positioned on the porous layer, and an etch stop layer positioned on the sacrificial layer, wherein the etch stop layer is thinner than the sacrificial layer, wherein the sacrificial layer comprises one or more protuberances that are integral with the sacrificial layer, wherein the protuberances extend through an entire dimension of the base, and wherein the removable plate is configured to be detachably coupled to the base using vacuum pressure supplied through the one or more vacuum channels and the porous layer;
- and a computer controlled motion system that allows the printhead and the stage to move in three dimensions relative to each other during operation of the 3D printer.
