Linear-immersed sweeping accumulation for 3D printing

This invention describes a special tool for 3D printing that uses light to harden liquid resin. Light enters one end of the tool and exits through a narrow, linear opening at the other end, which is submerged in the resin to build up an object. The claims specify this opening is formed by two inward-angled surfaces, has a width between 0.05mm and 2.5mm, and can be covered with a non-stick coating.

Why it matters: Since 2016, advancements in precision micro-fabrication and specialized non-stick coatings could enable more robust and effective manufacturing of this specific linear light tool.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPrecision optics, specific coating, laser integration
