Solved Bad Prints (Got Worse) can I fix this?

Hi, I just tested my first print at 1 micron to see if it would improve the print and although some areas are a lot better there are still holes in the print where its not fully covering the infill and an theres a part of the print thats warped a lot (always seems to be same spot) print quality has previously been better than this :S

 

Not sure what you mean with 1 micron - I'm assuming you mean .1mm layer height. (which is actually 100 microns). Definitely need more top and bottom layers like Mark says and your z-offset needs to be tweaked. Not sure which program you are using but in Mattercontrol under settings > printer in Start g-code (probably M565 Z-1.0) probably could be better at M565 Z-0.90. that should eliminate the stringing in the bottom layer

 

tyvm for quick responses! im currently using 0.6mm bottom/top (using cura but its same for gcode so tyvm) and yes 100microns my bad

 

any advice for the extremely disfigued part? the raft is fine but somehow that is still morphed :S

 

I would try .8 for bottom/Top thickness. For that model you shouldn't need a raft, something else is going on. Using PLA? What temp? Also what is the Print Speed? If using .1mm, your print speed shouldn't exceed 60mm/s (probably 30mm/s should be better) Also how much infill % are you using? Maybe a higher percentage might help.

Focus on the 1st layer. If that isn't printing right nothing else will work. That way you don't waste a lot of filament. In Cura I had to set my z-offset to M565 Z-0.75 for the first layer - so play around with that. I'm sure that is your biggest problem from what I can tell.

 

20% infill 60mm/s 200degrees ty ill try 0.75 atm my print wont stick to bed without a raft :S

 

blue tape and it even raft wont stick to that alone had to try stuff on top only thing i got to work was hair gel :S

 

dunno if this helps but I have upgraded to a e3d v6 hot end

 

thanks you guys!! its now printing without a raft and base looks perfect so far!! ill add pictures of finished print

all appears well printed at 0.2mm this time

 

I typically use at least 1mm of top fill layers. Smaller layer height = more top fill layers so something like this

0.3mm layer = 0.9mm top layers (3)
0.2mm layer = 1.0mm top layers (5)
0.1mm layer = 1.2-1.5mm top layers (12-15)

otherwise you tend to get pillowing. You can reduce those a bit but it sucks having a bad print because of not enough.

 

Thanks I had increased it to 1.2 (not sure if thats even possible) but im getting nice prints now
