ALKALINE-RESISTANT NEGATIVE PHOTORESIST FOR SILICON WET-ETCH WITHOUT SILICON NITRIDE |
摘要 |
A removable build box for a three dimensional printer comprises a build box tray defining a build chamber for part assembly and a material feed chamber for supplying powder material to the build chamber. The build and feed chambers have lower piston stops. A build chamber piston engages with the build chamber and with the build chamber piston stops at a lowermost position. A feed chamber piston engages with the feed chamber and with the feed chamber piston stops at a lowermost position. A quick connection coupling is between the build chamber piston and a build chamber z-axis actuator configured to move the build chamber piston when connected thereto. A quick connection coupling is between the feed chamber piston and a feed chamber z-axis actuator configured to move the feed chamber piston when connected thereto. The build box tray may be easily removed from the three dimensional printer. |
