The fundamental problem with multi-color 3D printing using a single hotend is that they poop an awful lot ... that there’s a path to reducing the waste stream from any printer, especially ...

After all that hard work, the printable area is a mere 37mm x 37mm x 18mm, but that’s not the point of this project ... If you’re digging this e-waste 3D Printer but want a larger print ...

There is a lot of waste that comes because of this process - Purged Filament or "Printer Poop". The A1 is a "Bed Slinger" and is an Entry Level 3D Printer. The X1-Carbon is an improved 3D printer.
