PLA-LW: The Future of Ultra-Lightweight 3D Prints

In recent years, the demand for materials that combine low weight, easy printability, and solid mechanical performance has been steadily growing. This is why PLA-LW – Light Weight PLA, also known as foaming PLA – is becoming increasingly popular.

How foaming PLA by Filament PM works and Why It’s Ideal for RC Models, Drones, and Prototyping?

PLA-LW is a modified PLA filament containing special additives that trigger active expansion (foaming) when heated. With the right printer settings, the material:

expands during extrusion reduces density significantly decreases the weight of printed parts and develops a smooth matte surface.

Recommended Printing Settings:

Parameter	Recommendation
Nozzle size	0.4 mm or larger
Print temperature	240 - 260 °C adjust for desired foaming. The higher the temperature, the higher the foaming
First-layer temp	200 - 210 °C (no foaming)
Flow rate	30 - 70% depending on foaming
Speed	mean values

ADVANTAGES	DISADVANTAGES
✅ Easy to print	❌ strong adhesion to the bed
✅ suitable for achieving low model weight	❌ Low-temperature resistance
✅ Can print huge parts	❌ Difficult post-processing
✅ Hard and tough
✅ No warping
