SYSTEM FOR DIGITAL FABRICATION OF GRADED, HIERARCHICAL MATERIAL STRUCTURES

摘要

A system to fabricate hierarchical graded materials includes a reservoir to contain a material to be deposited, a print head connected to the reservoir to allow the print head to receive the material to be deposited, the print head having a mixing section, and an actuator connected to the print head, the actuator configured to actuate the print head in six axes of motion.

1. A system to fabricate hierarchical graded materials, comprising:
a reservoir to contain a material to be deposited; and a print head connected to the reservoir by a conduit to allow the print head to receive the material to be deposited, the print head having a mixer to mix the material to be deposited with mixed fluid volume control no larger than a characteristic voxel size, wherein a voxel is a three-dimensional droplet of the material, and a fluid particle alignment section to receive the material from the mixer, the fluid particle alignment section to align fibers within the material to have arbitrary alignment relative to at least one nozzle, wherein the nozzle is connected to the fluid particle alignment section.
