+ | The VP75 is built from a powder coated sheet-metal frame, covered with acrylic panels on the front. Its main functional sections are the upper [[#Build chamber|build chamber]] and the lower [[#Filament drawer|filament drawer]]. The build chamber is providing insight through its translucent door during production. It contains all mechanical components. At the rear side, the [[#Connections|connections]] for ethernet, compressed air and mains supply can be found.\\ \\ The [[#Touchscreen|touchscreen]] for operation is mounted at the front.\\ | ||

+ | The build chamber is the main production area with the vertically moving [[#print-table-and-print-bed|print table]] and the two-directional horizontally moving extruder head inside.\\ All [[#Drives|electrical motors]] are installed at their working point and equipped with a water cooling system. The [[#Extruder head components|extruder head]] moves on an H-frame, tooth-belt-driven by two separate stepper motors in X- and Y-direction. The [[#Print table and print bed|print table]] is lifted and lowered in Z-direction by a spindle drive.\\ | ||
+ | For regulating the temperature inside the build chamber two heating resistors in separate housings heat the air which then is circulated through the chamber by the fans.\\ | ||
+ | Cables and hoses are installed in and guided by cable carriers.\\ | ||
+ | To minimize air pollution from dissolved substances, an additional fan circulates the air through a filter element filled with granules of activated carbon.\\ | ||
+ | The access to the build chamber is the magnetically closed double door at the front. | ||
