Lightweight PLA for RC and Cosplay

eSUN Super Lightweight PLA is a foaming filament designed for makers who need low-density parts. It targets builders of model aircraft, drones and cosplay props where weight savings matter. The material prints on any FDM printer that accepts 1.75 mm filament. Buyers who need structural rigidity or high-temperature resistance should choose a different polymer.

Foaming Window and Temperature Limits

Active foaming begins between 210 °C and 270 °C, expanding volume by roughly 1.2 times and allowing extrusion rates as low as 45 %. Most PTFE-lined hot-ends cannot run above 250 °C for extended periods without risk of clogging; printing hotter requires an all-metal throat. The supplier notes a usable range of 190–270 °C, but sustained operation above 250 °C is a practical constraint.

Installation Notes and Common Pitfalls

The spool uses full mechanical winding and manual inspection to minimise tangles and ensure smooth feeding. First-layer speed must match the print speed at 100 % with no slowdown, and first-layer flow must mirror the foaming rate — for example 45 % at 270 °C. Yellowing after high-temperature foaming is normal; lowering the temperature reduces it. Build-plate options include textured paper, PVP glue or PEI sheets.

Questions about this item

How does the foaming ratio affect how much model I can print from one spool?

At a 220% foaming volume ratio, one 1 kg spool yields the same printed volume as 2.2 spools of ordinary PLA, so you get more parts per roll.

What does the 1.2× volume increase mean for extrusion settings?

When the filament foams near 210–270°C it expands about 1.2 times, so the extrusion rate can be dropped to 45% to produce lightweight parts.

What temperature ceiling does the 250°C limit impose on my printer setup?

Most PTFE-lined hot-ends cannot run above 250°C for long periods; printing hotter requires an all-metal throat to avoid clogging.
