Abstract
The present disclosure provides a micro-composite material used in the fabrication of three-dimensional objects, and associated methods and systems. In one example, a micro-composite material used in the fabrication of a three-dimensional object can comprise micronized polymeric particles; a photocurable curing agent; and a dye present in the micro-composite material in an amount at from 0.0001 wt % to 0.1 wt %, the dye having a λmax between 350 nm and 800 nm.
Claims15
A micro-composite material for three-dimensional printing, comprising:
- micronized polymeric particles;
- a photocurable curing agent;
- and
- a dye present in the micro-composite material in an amount from 0.0001 wt % to 0.1 wt %, the dye having a λmax from 350 nm to 800 nm.
A method of manufacturing a micro-composite material used for three-dimensional printing, comprising:
- identifying a light source for curing the micro-composite material;
- and
- preparing micro-composite material by admixing micronized polymeric particles, a photocurable curing agent that is photocurable using the light source, and from 0.0001 wt % to 0.1 wt % of a dye having a λmax within 50 nm of light emittable from the light source.
A device for fabricating a three-dimensional object from a micro-composite material, comprising:
- an ejector for ejecting the micro-composite material, the micro-composite material including micronized polymeric particles, a photocurable cross-linker, and a dye, wherein the dye has a λmax;
- a light source for curing the micro-composite material;
- and
- a light source controller to cause the light source to emit light within 50 nm of the λmax.
