I have been using an UP Plus 2 printer extensively, to print ABS parts since 2013. It has always produced great quality prints from day one, and they still come out the same every time. I recently purchased a brand new UP Box+ after trying a couple other printers and slicers. I realized that Tiertime’s slicer is about as good as it gets for ABS. I fully expected at least equal quality prints, if not several years of evolution towards even better quality.
To my surprise, the Up Box+ does not even come close to the quality I get from my old UP Plus 2. I am currently trying to chase down possible causes for the differences and will post some pictures after I get some examples to show. I was able to print the same part on both printers with the latest UP Studio software. I had been using a very old legacy UP software for my UP Plus 2, which was always just fine. Hopefully, the new parts I am printing on both printers will eliminate the newest sofware from one of the possible differences.
The next thing I will be looking at is the Hepa filter fan. The part artifacts I am getting on the UP Box+ is very much like “fuzzy skin”, which could very easily be related to the significant vibration induced by the Hepa filter fan. I will be disconnecting the fan and printing another part to see if this could be a factor. Has anyone else with both printers noticed this difference in print quality, and been able to figure out why?
