13 Post-processing Once parts have been retrieved from the printer, they should be cleaned of excess material. HP recommends removing loose excess material and large clumps of material from each part before bead blasting. This will preserve the color of the final parts as well as the lifespan of bead-blaster filters and glass beads. After this loose material is removed, the remaining material will have to be removed in a bead- and air-blast machine. All parts should be bead blasted (first) and air blasted (second). ● Bead blasting consists of applying compressed air mixed with an abrasive material to the part in order to remove the attached material. HP recommends blasting parts with glass beads of diameter 210-297 µm (50-70 mesh). ● Air blasting consists of applying compressed air to the part in order to remove any material remaining after bead blasting. The following options are available to improve surface finishing: ● Tumbling: The part is immersed in a vibro-tumbler full of abrasives, to smooth any surface roughness. ● Hand sanding: The surfaces of the part are smoothed by abrasion with sandpaper. Other industry-standard postprocessing methods may be used: ● Coatings for wear resistance, conductivity, temperature resistance, strength, watertightness, resistance to chemicals, gloss properties, and so on ● Gluing, bonding, sealing ● Drilling, tapping ● Plating Contact your service representative to discuss solutions for your specific needs. Consult your usual EHS specialist for advice on the appropriate measures for your location depending on the post-processing method you use. Consult your local authorities to determine the correct manner in which to dispose of wastes. Post-processing 69
