The reduction of weight allows the printer head to move much faster and accelerate quicker. If you look at the video above, you can see the printer move rapidly at 200 mm/s.

The extruder is a remote direct drive. You can make prints like these with NinjaFlex and other flexible material that would be nearly impossible with a bowden setup.

Unfortunately, if the project can't get enough support in the next 2 weeks, this project will not be funded. Nobody would be able to buy one, so please help back the project.
