THREE-DIMENSIONAL ADDITIVE FABRICATION WITH SUPPORT FLUID - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240278494 titled 'THREE-DIMENSIONAL ADDITIVE FABRICATION WITH SUPPORT FLUID

The abstract describes a method for additive manufacturing of three-dimensional workpieces using a support fluid build.

• Dispensing resin in a liquid state into a container
• Polymerizing the resin layer with light to form a current build layer
• Advancing the build platform to submerge the current build layer in the support fluid
• Successively building the workpiece in the support fluid

Original Abstract Submitted

this disclosure provides methods and systems for the additive manufacturing of three-dimensional workpieces using a support fluid build. in one aspect, a method is provided for forming a three-dimensional workpiece, the method comprising dispensing a resin in a liquid state into a container, irradiating at least a portion of the resin layer at the fluid interface with light to polymerize an irradiated portion of the resin layer as a current build layer of the three-dimensional workpiece at the fluid interface, wherein a portion of the three-dimensional workpiece is affixed to a build platform immersed in the support fluid; and advancing the build platform to a next position in the support fluid to submerge the current build layer within the support fluid. the process is repeated to successively build the workpiece in the support fluid.
