Methods and apparatus for compressing material during additive manufacturing

This invention describes a 3D printing process where a machine deposits a layer of fiber-reinforced material and then immediately presses it down with a roller. The roller, which has a flat center and angled ends, is attached to the printing head and compresses the material as it's laid down. The claims specifically focus on using fiber-reinforced material.

Why it matters: Since 2020, advancements in fiber-reinforced material science and more precise real-time process control for additive manufacturing have emerged. These changes could make the benefits of compressing fiber-reinforced layers more significant or easier to implement, addressing common challenges like porosity and anisotropic properties.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCNC integration, custom roller, applicator mechanism.
