eSUN grey PLA filament is a 3D printing material produced by eSUN. Made from corn starch or sugar cane, this filament is completely biodegradable and non-toxic. As part of the eSUN PLA material series, it is among the cheapest yet effective 3D printing filaments currently available on the market.

It offers good toughness and strength. It is characterized by a good round shape and an accurate yet uniform diameter of 3mm (2.85mm). Its low melting temperature makes it printable on almost any FDM 3D printer with or without a heated bed. It runs out smoothly streamlining the 3D printing process while reducing the risk of printing failures caused by filament jams or clogging. 

Easy to print, this grey PLA filament is a general-purpose material. It allows producing quite complex solid grey objects with crisp edges and a great number of details. Printed parts show slightly glossy surfaces. Ideal for children, students, makers and 3d printing experts, eSUN grey PLA can be safely used in small, poorly ventilated rooms with no health risk. It is available in 1kg filament spools.
