“Portable CoreXY 3D printer(foldable)
The 3D printer has a compact size so that it can fit in a large backpack. It was essential for me that the printer has a reasonable print volume despite the requirement to be portable. The outer dimensions are 300x330x105mm (folded), and the build volume will be 160x220x150mm (XYZ).
As you can see in the renderings, the printer will unfold during printing. The printer will be built out of CNC machined aluminum parts and 3d printed ones.
I chose aluminum in the first place because I wanted to build the printer as rigid as possible (proof of concept).
To obtain rigid joints, the printer uses a combination of axial and radial bearings. Three screws then preload each axial friction bearing.”
