Our RepStrap nearly finished printing all neccessary parts for its first child, a Prusa Mendel v2. Only the Extruder is missing.
Yesterday Jonas made a short video of the RepStrap printing.
The Printer should primarily serve the purpose to make a ‘real’ RepRap-Prusa from printed parts. Since I managed to get reasonably useful (and mechanically robust) print results, step by step set of parts for a RepRap-Prusa was completed. Further calibration and optimization of print quality took place throughout the process.
Initially we started printing with a spool of PLA-90 from Orbi-Tech – a german supplier for 3D-Printer Filament. They sell this special type of PLA as beeing more heat resistant than standard PLA (getting weak at 90°C). Unfortunately this PLA blend is much harder to print, especially without a heated printbed. Although Orbi-Tech claims this “premium PLA” warps less than standard-PLA, we could not confirm that. So after a lot of fine Tuning and experimenting we switched to white Standard-PLA (from Orbi-Tech as well) for the remaining prints.
In the picture above all parts that are a little darker (light grey) were made of PLA-90. The bright white plastic is the standard-PLA.
Btw – Jonas started the RepStrap Build Log with part 1, describing our frame design.
