1. A materials kit for 3D printing comprising:
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, the composite fibers including glass fibers at from about 5 wt % to about 40 wt % based on the total weight of the powder bed material, wherein the glass fibers include at least one of glass fibers coated with an encapsulating polymer, uncoated glass fibers, or a combination thereof; and
a fusing agent comprising an energy absorber to absorb electromagnetic radiation to produce heat.
