4. For optimal part quality, remove each part with all attached material. Do not allow any excess material to fall back into the build chamber. CAUTION: Do not brush or forcibly scrape loose material attached to the parts back into the build chamber. 5. Continue until all parts are retrieved from the build chamber. Use the buttons to lift the platform to reach all parts. 6. After parts have been removed from the printer, additional cleaning with hands or a brush may be used before bead blasting. This will preserve the color of the final parts as well as the lifespan of the beads and filters. This material may not be returned to the printer as it will compromise the part quality of subsequent builds. 7. Material may remain on the build platform. Additional reclamation may be initiated by pressing the Reclaim and Finish button. NOTE: All doors, and the top cover, must be closed before starting to reclaim material. CAUTION: Do not reclaim material that has been fused. NOTE: Some material may remain at the edges or frame of the platform. Once the front panel tells you that the process has finished, you may want to check whether all material has been reclaimed. To remove any remaining material, use an external explosion-protected vacuum cleaner. 8. With all parts clean and excess material reclaimed, resume normal printing. Keeping the printer clean If a significant amount of material falls from the top cover after a build, the following precautions may be useful: 1. Tap along the front of the top cover before opening it. 2. Slowly open the top cover about 25 cm (10 in), and use an explosion-protected vacuum cleaner with a soft-brush nozzle to remove material from the edge of the cover. 3. Continue opening the cover slowly, without releasing it, until it is fully open. 4. Vacuum the interior surface of the cover to remove any remaining material. 5. Place a vacuum hose near the top of the build chamber to remove dust during parts retrieval. 68 Chapter 12 Cooling and part retrieval
