Most FFF (Fused-Filament Fabrication) 3D printers can be categorized as one of two types: Cartesian or delta.

 .

Cartesian 3D printers are, by far, the most common, and represent a typical design with three axes that move independently off each other.

 .

Delta 3D printers have the hot end mounted on three arms that move vertically, and all three have to work together to move in any single axis.

 .

Cartesian 3D printers are the easiest to control, have a rectangular build area, and tend to be very rigid. But they’re also bulky, which is why Malte Schrader developed this innovative 3D printer that folds for portability.

 .

Unlike other 3D printers that can be broken down into smaller pieces for transportation, this “X Printer” uses the folding mechanism during the actual printing process. In place of a conventional Z axis, which rides on linear rails and lead screws, this design has […]
