Mendel Specifications
The table below outlines the specifications of the machine.
| Metric | |
|---|---|
| Model | Reprap II: Mendel "Mendel" |
| Technology | FFF (Fused Filament Fabrication)/Thermoplastic extrusion |
| Price of all materials | €350 |
| Annual Service Cost | Occasional oiling = €5. It can print its own replacement printed parts at material cost. |
| Size | 500 mm (W) x 400 mm (D) x 360 mm (H) |
| Weight | 7.0 kg. |
| Build Envelope | 200 mm (W) x 200 mm (D) x 140 mm (H). |
| Materials | PLA, HDPE, ABS & more. Uses ø 3 mm filament. |
| Material Cost | PLA: €22/kg, HDPE: €11/kg, ABS: €17/kg. |
| Speed | 15.0 cm3 per hour solid (test done for PLA, similar for others). |
| Accuracy | Diameter of nozzle 0.5 mm, 2 mm min. feature size, 0.1 mm positioning accuracy, layer thickness 0.3 mm |
| Finish | Fair |
| Volume of printed parts to replicate | 1110 cm3 |
(With the standard infill settings the 15.0 cm3 per hour solid extrusion rate is equivalent to a built volume rate of 19.0 cm3 per hour.)
Electronics
The current thinking is that User:samthetechie will prototype an experimental board design http://reprap.org/wiki/Teensylu with Chris and Glen.
