Lightweight PLA for FDM printers

eSUN Super Lightweight PLA is a 1.75 mm filament designed for all FDM 3D printers. Its foamed structure reduces density to 0.54 g/cm³ so printed parts are significantly lighter than standard PLA. The material suits model aircraft, drones and cosplay props where weight matters. One 1 kg spool yields roughly 2.2 times the printed volume of ordinary PLA.

Active foaming changes print behaviour

The filament expands up to 220 % during extrusion when temperature is raised between 210 and 270 °C. Higher temperatures increase foaming and lower part density while lower temperatures give denser, stronger layers. This single material replaces multiple spools for different weight targets. The matte surface finish takes paint easily without priming.

Dimensional tolerance sets the practical limit

Diameter accuracy is held to ± 0.05 mm so most direct-drive and Bowden extruders feed it reliably. The low-density melt can string if retraction is not tuned, and very high foaming reduces layer adhesion compared to solid PLA. Printed parts are more brittle than unfoamed filament so they suit non-structural shells rather than load-bearing frames.

Questions about this item

How often will the 1.75 mm nozzle need cleaning when printing with this foaming PLA?

The filament is wound to prevent tangling and feeds smoothly without clogging the nozzle or extruder, so cleaning frequency stays low under normal use.

What temperature ceiling limits the foaming ratio during long prints?

The foaming volume ratio peaks at 220 % when the hot-end runs between 210 and 270 °C; exceeding that range reduces expansion.

How much heat does the spool add to an enclosed printer running all day?

With a density of only 0.54 g/cm³ the material extrudes at lower mass flow, so the hot-end deposits less thermal energy into the chamber during extended sessions.
