Curling and problem with inside edges ;/ Slic3r PLA Prusa i3

As on images you can find that project start curling on legs side (bed with glass 60 degrees + hair spray, it start curling after around 1hour).

Second problem is lack of connection between rounded edges and infill... It doesn't fill to the edge but leaving around 1-2mm...

Third problem is awful rounded edges... Not sure why it can't print nice edges...

I printed on 15mm/s on edges...

Prusa i3, Slic3r 0.9.9

Hey Mick,
I found that hairspray is not that good for PLA, I started using PVA mixed with water (1:10 ratio) applied to a heated bed a few times works alot better for the PLA prints I have done. May not fix all your problems but should help with curling and maybe curves.

Tim

I will try it then.


So hair spray only for ABS ?

not all hair spray is the same, if one brand doesn't work try another brand

A surefire way I have found to work well with RepRapWorld PLA is glue stick applied to the heated bed.
Different brands will yield different bonding strength:
UHU: had to chisel the parts off, ultimate bond. Probably, soaking the glass plate in water for a long enough time might help with part removal.
Tombow: Bonds really well, after the bed has cooled to nearly ambient, the parts just snap off.
Coccoina liquid glue stick: similar to Tombow, just that it is in liquid form.

PVA Glue mixed with a little water. bed at 65 - 70 C cannot go wrong with PLA will stick like crazy and crack off nice at 30C.

it sticks so good i am able to run a 120mm fan blowing over the whole bed while printing lol

if you find you still get lift add more glue less water etc.

iv tried hairspray it does stick but i get lift but it was a cheapo brand haitspray. i know richrap uses hairspray and has no problems i would say it depends on brand were as PLA glue is PLA glue.

on that note dont use Wood Glue ! its not the same stuff has added extras to work better with wood(unless its super cheapo wood glue lol)

I can confirm that PVA worked...

So far so good,


Thanks guys !

The edges not touching and the not onus round edges is because there is some backlash in at least one of your X/Y axis.
I would check your belt tension, and that the sett screws on the pulleys are tight.
