How to print LW-PLA?
The basic print setup is almost the same as we use for standard
PLA. The only difference is in extrusion multiplier set to 0.5 and
turning off the retractions completely.
This results in parts with half the weight and still suitable
mechanical properties, but expect some heavy stringing inside
and outside. Of course you can try to tweak the retractions for
less stringing inside the parts, but there‘s a high risk of clogging
the nozzle or throat. Increasing the retraction distance above
1 mm is not recommended at all and leads to nozzle clogs
caused by foaming. Cleaning the hairy, but functional parts
after printing with retractions completely disabled seems to be
more efficient method. The nozzle is permanently pressurized
and you don‘t need to worry about print failures. This method
works fine even for bowden printers.
Extrusion multiplier 0,5 has been tested for easy print with
massive weight saving around 50%. Feel free to experiment
with extrusion multiplier and temperatures at will for the best
results on your printer.
Cosmetic issues of the prints are easily fixed with snap knife or
sand paper, as the LW is easily sanded and cut.
