Introduction

The Rostock mini made by Geeetech 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 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.

Features: 1. Mini- size & light weight, more compact & portable compared with other Delta RepRap design.

2. Fixed printing platform, parallel kinematic XYZ axes with low accumulated error, ensuring high precision & speed of printing.

3. Bakelite print platform with treatment of sand blast and anodization; polished oxidized high borosilicate tempered glass. Compared with aluminum sheet and acrylic sheet, the has advantages of high mechanical strength, good insulation, good heat resistance and good corrosion resistance
