how can you improve this print? in Help, Tips & Tricks Posted July 21, 2016 · Edited July 21, 2016 by Guest Added a clarification. Ooh - I wouldn't turn off the bed for this one. As long as fan is 100% you shouldn't need to lower the bed temp. This part has a small surface contact and you don't want brim so it's hard to get it to stick well without glass-and-glue-and-heat. But, yeah, you could use blue tape but then you have to re-level and make damn sure the bottom layer is squished and make sure you clean the wax off the blue tape with alcohol. Really I would avoid blue tape unless you are ready to waste a few prints learning a new technology. All good points. I have previously learned how to blue tape and re-level and alcohol, etc., as you say, so I did not think about the learning curve. I was trying to get this to print a while ago: http://www.thingiverse.com/thing:986729. But the undersides were always rough. When I went cold bed and 0.15 layer height (vs 0.1), I was able to get nice clean curved undersides. Virtually flawless, actually. I was just thinking that same technique could apply here, though I did not bother when I printed the OPs piece. But as you say, that is a whole bit of new learning and retooling too. Anyway, YMMV. If there is a different/better way, I would sure be interested in hearing about it. Oh, and I was assuming PLA. I would not suggest cold bed for ABS.
