Abstract: A materials kit for 3D printing can include a powder bed material including from about 60 wt % to 100 wt % composite fibers having an average aspect ratio from about 3:1 to about 30:1 and a fusing agent including an energy absorber to absorb electromagnetic radiation to produce heat. The composite fibers can include glass fibers coated with an encapsulating polymer, wherein the glass fibers can be included at from about 5 wt % to about 40 wt % based on the total weight of the powder bed material.

The build material composition includes a polyamide having a melt enthalpy ranging from greater than 5 J/g to less than 150 J/g. The fusing agent includes an energy absorber to absorb electromagnetic radiation to coalesce the polyamide in the at least the portion. The fusing agent is a core fusing agent and the energy absorber has absorption at least at wavelengths ranging from 400 nm to 780 nm; or the fusing agent is a primer fusing agent and the energy absorber is a plasmonic resonance absorber having absorption at wavelengths ranging from 800 nm to 4000 nm and having transparency at wavelengths ranging from 400 nm to 780 nm.

Abstract: In some examples, a method measures values of a property of a build material aged in a heated environment, and computes, using a predictive model for each of a plurality of recyclability ratios, output values of the property over a plurality of generations of the build material, each recyclability ratio of the plurality of recyclability ratios representing relative amounts of fresh build material and used build material. The method further includes presenting the output values of the property over the plurality of generations to enable selection of a recyclability ratio to use in building a part using the build material.
