At the university College of Ghent we have done some printing tests. We have been building several RepRap/Mendels now, and divide them systematically in two categories.
- Alpha ones: These RepRaps are built with pieces of two or more different RepRaps. Important to notice is that these machines do not belong to the same tree. (These RepRaps doesn't have pieces printed by the same parent.)
- Beta ones: These machines consist of pieces by only one parent. Or worse, by pieces from RepRaps with a mutual parent.
Findings:
- The Alpha RepRaps have very good prints. The quality is really awesome! Some pictures:
- Far worse is the quality of the Beta ones:
Further research:
As from today the University College Ghent will have Peter Van Ransbeeck doing his PhD on the subject of "Print quality of RepRap - Purifying the RepRap tree", in dutch: "Raszuiverheid der RepRaps". He will research these findings in greater detail.
If you have some information for us, please leave a note in the comments. Or contact me at: Batist.leman [at] gmail.com. Any of your results or findings could be very useful for us.
This is a very important issue, and we don't now the cause of this... yet.
