A powder for solid freeform fabrication includes a first resin particle and a second resin particle, wherein MFR2 is greater than MFR1 and a ratio of MFR2 to MFR1 is from 2 to 5, where MFR1 represents a melt mass-flow rate (MFR) of the first resin particle and MFR2 represents a melt mass-flow rate of the second resin particle.

Novel plumbing products, including faucets, are fabricated, e.g., using metallic 3-dimensional or other 3-D printing techniques, to have complex geometries, such as multiple channels that may diverge and re-converge near the spout. The geometries of the various channels can resemble interwoven net-like patterns that define various shapes between the channels. The plumbing fixtures may be formed from one or more of stainless steels, INCONEL, brass, bronze, polycarbonate, PVC, acrylics, rigid polyolefins, PET, carbon fiber, AES, or other plumbing fitting suitable corrosion resistant materials. In some embodiments, the handles of an exemplary faucet can include the same or a similar multiple channel configuration as the spout, providing an advantageously, aesthetically pleasing faucet system. In exemplary embodiments, faucet spouts and their handles are formed so as to couple to standard faucet underbodies, standard valve platforms, or standard threaded hose/waterway connections.
