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.
