how can you improve this print?

Recommended Posts

Any chance of inverting the object? That would avoid those particular overhangs, although you would get problems with that horizontal slot.

Otherwise try printing the shells much slower. A lower temperature may help a bit.

 

Hi JohnFox, the printing temperature is 205°C material is PLA speed 45mm/s height 0.1

is not more speed, I think that is correct

Also, turn off the heated bed (bed temp set to 0) and use blue painters tape for adhesion. Radiated heat from the bed makes overhangs like that rougher/saggier.

Also, consider that since that specific part will be inserted into the outer case, that the looks of the underside are not that important. Especially compared to getting a nice clean square for the socket to attach to. :)

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.
