Abstract: A materials kit for three-dimensional (3D) printing can include a powder bed material including from about 60 wt % to 100 wt % composite fibers including glass fibers coated with an encapsulating polymer, wherein the composite fibers have an average length of from about 100 μm to about 700 μm and an average diameter of from about 20 μm to about 70 μm. The materials kit for 3D printing can also include a fusing agent including an energy absorber to absorb electromagnetic radiation to produce heat.

Abstract: The present disclosure describes three-dimensional printing kits, methods of making three-dimensional printed objects, and three-dimensional printing systems. In one example, a three-dimensional printing kit can include a power bed material including thermoplastic polymer particles, a fusing agent to selectively apply to the powder bed material, and a post-processing agent to apply to a three-dimensional printed object. The fusing agent can include water and a radiation absorber that absorbs radiation and converts the radiation energy to heat. The post-processing agent can include a curable epoxy resin, where the epoxy resin, when cured, has a higher elastic modulus than the thermoplastic polymer particles.

Abstract: This disclosure describes three-dimensional printing kits, methods, and systems for three-dimensional printing with directionally-dependent reflective particles. In one example, a three-dimensional printing kit can include a powder bed material and a fusing agent to selectively apply to the powder bed material. The powder bed material can include polymer particles and directionally-dependent reflective particles. The directionally-dependent reflective particles can be chemically and thermally stable at a melting point temperature of the polymer particles. The fusing agent can include water and a radiation absorber to absorb radiation energy and convert the radiation energy to heat.

Abstract: Examples of the present disclosure are directed toward methods and system for reducing surface roughness of a cured three-dimensional (3D) printed object using a localized heat source. An example method includes applying a liquid solvent to the cured 3D printed object and heating the cured 3D printed object with the liquid solvent applied thereto to a temperature below a melting point of the cured 3D printed object using a localized heat source to reduce a surface roughness of the cured 3D printed object as compared to the cured 3D printed object prior to the application of heat.

Abstract: A three-dimensional printing formulation can include polymeric powder. The polymeric powder can include high aspect ratio composite particles including glass fibers coated with an encapsulating polymer in an amount from about 5 wt % to about 80 wt % based on a total weight of the polymeric powder, and low aspect ratio filler particles in an amount from about 20 wt % to about 95 wt % based on a total weight of the polymeric powder. The high aspect ratio composite particles can have an aspect ratio from about 7:1 to about 30:1 and the low aspect ratio filler particles can have an aspect ratio from 1:1 to less than 7:1.
