Yea they should work fine, all the the jointed stuff on thingiverse prints out great for me. You should make sure your rafts and stuff come off very easily because if they don’t you need to tweet your filament or printer settings. Mine comes off with just a little tug. One thing that I noticed made knight and day difference is the quality of filament it truly makes the experience 100x better. I print with 60 dollar a roll abs and things are pretty great. Good luck
PLA is the easiest material to print if you are starting to 3D Printing, about printer settings, you should try to print a piece with different settings using your 0.4 mm and 0.2 mm nozzles (for example: layer height 0.25 mm, 0.1 mm and 0.06 mm), about infill 20% to 30% is always pretty good unless you are printing a piece with mechanical movements. Speed: try using 40 to 60 mm/s, Cooling: depends on material, PLA uses 100% cooling, CPE and ABS try avoid any cooling and print in a room with temperature about 23 to 25 degrees Celcius. Hope you do great. Regards.
The UM2+ has very high acceleration compared to most printers so 40mm/sec on the UM2 for a part less than 2 inches across is probably about the same as 100mm/sec on a typical printer. For printing long straight lines like printing a large cube the speeds are almost identical. But anyway you will get amazingly better quality if you slow it down to 35mm/sec on the UM2 series printers. It all depends on if you want beauty or functionl
Also, to get tolerances exactly right without changing the original design file, you can expand or contract the toolpaths in the latest Cura releases (2.x). See also the screenshot image I added. Also, real time adjustment to the printer’s flow rate could be helpful in getting things to have gaps of < 0.05 microns and still be separate parts.
If you have a dual extruder, print the part in ABS and the 0.5mm gap in HIPS. Let the finished part sit in Limonene (i order mine from Amazon) for a bit. It will dissolve the HIPS and doesn’t affect the ABS.
