3D Printing Tips
Standard PLA Temperatures:
We see good results printing Paramount3D PLA at 220
ºC
with a bed temperature of 70ºC. Experiment with your
particular printer and brand of material to ensure proper
layer bonding but you will likely land somewhere between
210 and 240ºC.
Cooling Fan:
Typically, PLA is printed with the fan set to 100%. However,
this can cause layer bonding issues when printing thin walled
aircraft. We have experienced nice , clean outer surfaces
when keeping the fan speed up to 20% without negatively
affecting layer bonding. Experiment with fan speeds set
between 0 - 20%.
ColorFabb LW-PLA
ColorFabb LW-PLA is an interesting material that uses foaming
technology to achieve lightweight, low density PLA parts. This
material is printed at a higher temperature (which causes it
to expand) and a much lower extrusion multiplier than standard
PLA. In order to determine the proper nozzle temperature and
extrusion multipler for your particular printer you can follow
ColorFabb’s instructions:

We had good results printing LW-PLA at 250
ºC at an Extrusion Multiplier of 0.4
and a bed temp of 60ºC. You will also likely combat quite a bit of stringing with
LW-PLA. We increase X/Y Axis Movement Speed to 200mm/s and run the cooling
fan at 25% to help combat stringing. The LW-PLA version of Micro SportCam has
also been designed with few lightening holes to help minimize stringing.
