What this filament is and who it suits

eSUN PLA+ is a 1.75 mm PLA filament on a 1 kg spool with a grey finish. The material is an upgraded PLA that offers higher strength and toughness than standard PLA while keeping low shrinkage and minimal warping. It is aimed at hobbyists and professionals who need reliable, dimensionally accurate prints on any FDM printer. The spool provides roughly 340 to 350 metres of filament.

What to verify on your printer before ordering

Your printer must accept 1.75 mm filament and have a heated bed capable of 45 to 60 °C. The hot end should reach 210 to 230 °C, with 215 °C recommended for best results. A cooling fan running at 100 % speed is advised, and print speeds of 40 to 100 mm/s are supported. Suitable build surfaces include textured paper, PVP glue or PEI sheets. The vacuum-sealed pack with desiccant keeps the filament dry until use.

What this upgrades from and when the jump matters

This PLA+ replaces standard PLA when you need stronger functional parts, better layer adhesion or consistent feeding at higher speeds. The tight ±0.03 mm diameter tolerance reduces clogging and stringing on machines such as Bambu Lab X1, P1P, A1 series, K1 series, Prusa, Ender 3 and many others. It is not suited for applications that demand high-temperature resistance or engineering-grade mechanical properties beyond improved PLA performance.

Questions about this item

What comes in the box and do I need to buy anything else to start printing?

The spool arrives vacuum-sealed with a desiccant bag inside the bag. You only need a compatible FDM printer and a heated build surface such as textured paper, PVP solid glue or PEI.

Which diameter and weight should I choose for my printer?

This listing is the 1.75 mm diameter on a 1 kg spool (2.2 lbs), the standard size for most FDM printers including Bambu Lab, Prusa, Ender 3 and UltiMaker models.

What does the ±0.03 mm tolerance mean for my actual prints?

The tight diameter tolerance keeps filament feeding consistently through the extruder, reducing clogs and stringing so you get stable layers and a high success rate at 40–100 mm/s print speeds.
