PolyLite™ LW-PLA is a low-density PLA that uses Polymaker’s Stabilized Foaming™ technology. This technology allows the PLA to re-foam after extrusion introducing a lattice foam structure that decreases the density by 30%. It prints using regular PLA settings and also produces a naturally matte surface finish which can hide the layer lines. LW-PLA is the perfect candidate where weight is critical and is popular among aerodynamicists.
What is the difference between active foaming and passive foaming?
PolyLite™ LW-PLA is not an active foaming filament, which means it will not foam when extruded from the nozzle depending on the temperature. PolyLite™ LW-PLA is already pre-foamed.
What are the pros and cons between active and passive foaming?
You need to heavily modify your printing settings depending on the temperature and setup to compensate the foaming expansion of the material when printing.
You need to print at very high temperature to achieve light weight results (~250_), these high temperatures will create a lot of defects on the print such as stringing and blobs.
At very high temperature, active foaming can achieve lighter print than passive foaming however the print may suffer of serious stringing defects.
You do not need to change any settings from your regular PLA settings (slight increase retraction) as PolyLite™ LW-PLA will offer light weight results even when printing at very low temperature (~190_C).
The lower the temperature the higher quality the print.
Is PolyLite™ LW-PLA good for RC Plane?
Yes, PolyLite™ LW-PLA is designed for ease of print and strong rigidity. For more information check out the review below about PolyLite™ LW-PLA for RC Plane application.
Jam-Free™ technology improves the heat stability of Polymaker’s PLA filaments with softening temperatures over 140 °C. As a result, Polymaker’s PLA filaments show minimal softening in the “cold end” and can melt rapidly once entering the heating zone, leading to excellent printing quality with zero risk of nozzle jams
