Overview
eSUN Lightweight PLA — foaming agent causes PLA to expand at high temperatures, creating a foam-like low-density structure. Used for RC aircraft, drones, and weight-sensitive applications. Use 50-75% of normal flow rate.

Pros
  • Low density foam effect, great for RC planes and lightweight structures, huge volume savings
Cons
  • Very niche use, can clog at wrong temps, needs tuning
Best For
  • RC aircraft fuselages
  • drone components
  • any weight-critical application where strength-to-weight ratio matters
Laser Compatibility
LASER INTERACTION Safety: SAFE — PLA base polymer. Standard ventilation sufficient. CO2 engrave: 300-400mm/s @ 15-20% | Diode 20W: 3000mm/min @ 35% Result: Clean dark marks. Good contrast on light colors. Fumes: Lactic acid derivatives — low hazard. Note: Foam structure has lower density and more air pockets — laser absorbs differently. Settings will vary significantly from solid PLA.
