8.1 Clean the Waste Tray
Located at the bottom of build chamber, a waste tray is introduced in UP300D. 3D
printing with plastic extrusion technology is a messy business. Normally lots of
unwanted plastic scraps are generated here and there during printing and the post
processing stage. It is a nightmare to clean it up especially for the machine with full
enclosure.
The waste tray makes the cleaning work fast and easy. You can take the whole tray
out and dump the scraps inside the tray to a dumpster, and put it back to the bottom
of the machine.
8.2 Dual Filtration System
UP300D has the upgraded air filtration system inherited from UP BOX+ with bigger
and better Dual Filtration System - the HEPA Filter and the Activated Carbon Filter.
Both of the filters are located inside the build chamber, circulating the air internally to
reduce the toxic particles generated during the 3D printing process.
