ROSTOCK MINI - DELTA PRINTER
The Rostock mini is a delta 3D printer based on the modified design of the original Rostock created by Johann. The printer is designed to have a smaller build volume allowing for a smaller, more compact, portable, and desktop friendly version of the delta RepRap design. Using OpenSCAD, the parametric nature of the design files allows for print surfaces to be configured that range from as small as the default 152x152 mm (6x6 inches) all the way to 300x300 mm (12x12 inches) or more. Further, construction parameters such as the length of the drive belts, diagonal rods, and a laser cuttable frame as well as the firmware parameters such as diagonal rod length and delta radius are all automatically calculated based on the size of the specified print surface.
PRUSA MENDEL I2 - CARTESIAN PRINTER
This is the first 3D printer I've ever made. But, what is a 3D printer? On a 3D printer the object is printed by three dimension. A 3D model is built up layer by layer. Therefore the whole process is called rapid prototyping, or 3D printing. A common process of rapid prototyping is to apply a fine powder in such a 3D inkjet printers. Printer print out the layer of powder on a bed and form a fixed object. The design is defined by a CAD file.
