I am consistently getting melted layers when I try to print this chess figure at the following settings:
Temp: 190
Bed: 45
Layer: 0.2mm
Infill: 75%
Played with speeds, same results. Looks like as it progresses to the higher layers, they start melting and sinking.
Any advice?
this happens when the previous layer hasnt had enough time to cool before the next layer is printed. You can try putting a fan over the print area, or try printing multiple parts at one time to give time for cooling.
You can try printing multiple parts like Kronik said to allow the previous layer to cool more... if your set on printing this one piece I would suggest using less infill as giving it some breathing area within the print would probably help it solidify. I usually print everything at 15% infill but you can try it at 20-30% and it should be solid enough... I would also leave the front and top door open to allow more cool air to enter the print area.
As suggested here before, a sacrificial column can do wonders. I used Openscad to make a tall, skinny column and I place it distant to the printed object, just to give the layers some time to cool.
A layer fan can help a lot as well. Of course, not my idea... another pearl from the community.
With PLA, a fan is not optional, as you can see. If you don't want to wire one up to your machine, a desk fan blowing in the print area will work as a temporary solution, but you will likely have to re-run PID autotune with the fan blowing on everything.
^That
If you don't have the option of mounting a fan..
1) Remove any and all enclosures
2) Said desk fan and PID can help, but it is only a hail mary
3) Print a tall skirt as far away from the outer perimeter of the print as possible
4) With suggested 1-3 performed, slow your speed down slightly.
PLA needs longer times to cool, so keep this in mind first and foremost!
Do what Kronikabuse said,,I to had the same problem with small objects,so just added more of them to print at the same time and works great.
