Abstract
A method for forming a skeleton (e.g., space frame, trussed structure, regular foam, open-cell foam, closed cell foam, etc.) can include providing instructions for spatial locations of optical hot spots, generating the optical hot spots, and growing material at the optical hot spots to form the skeleton. The method can optionally include shaping the grown material and/or infilling the skeleton.
Claims20
A method of forming an interconnected foam comprising:
- generating a plurality of individual laser beams using a light modulator;
- focusing the plurality of individual laser beams onto a focal plane initially substantially coincident with a broad face of a substrate to produce a plurality of individual focused laser spots, wherein a focal spot size of each individual focused laser spot at the focal plane is between 1 um and 100 um;
- introducing a gaseous deposition precursor into a deposition chamber, wherein the substrate is arranged within the deposition chamber, wherein laser light enters the deposition chamber through an optical window, wherein material derived from the gaseous deposition precursor deposits within a locally heated region proximal the plurality of individual focused laser spots to form deposited material;
- and
- relatively moving the substrate and the individual focused laser spots;
- wherein the deposited material forms the interconnected foam.

A method for forming an interconnected foam comprising, within a deposition chamber:
- flowing a gaseous deposition precursor into the deposition chamber;
- focusing a plurality of individual laser spots on a focal plane initially substantially coincident with a broad face of a substrate;
- wherein within the individual laser spots a temperature of the substrate is greater than 300° C.;
- depositing material derived from the gaseous deposition precursor substantially only within a locally heated region within the individual laser spots to form deposited material;
- and
- moving the substrate relative to the individual laser spots;
- wherein the deposited material forms the interconnected foam.
