Prusament PLA Lightweight: foaming PLA for lightweight parts
1 min read
Prusa says its new foaming PLA can produce prints up to 65% lighter, targeting RC models, drones and other weight-sensitive parts.
Prusa’s new Prusament PLA Lightweight relies on foaming during extrusion. Heat activates additives in the filament, causing the extruded material to expand and form a more porous structure.
Prusa says finished parts can be up to 65% lighter than standard PLA. The material is aimed at RC models, drones, cosplay components and other weight-sensitive applications.
Because foaming depends on temperature, this is not simply a lighter PLA: slicing and thermal settings directly affect the final density.
