mark has a project to 3D print a 3D printer using a 3D printer so that it could 3D print items while being portable, the 3D printer is weighted around 3KG, so it won't be easy to carry it around like a casual laptop, but beneficially, the 3D printer is foldable, so by creating a bag with slots put the printer, it would be portable easier to be taken around the school or workplaces to 3D print items or maybe even 3D print another 3D printer using the portable 3D printer.
