PLA Filament

The eSUN eSteel is one of many PLA composite products produced by the company eSUN Industrial Co. Ltd. ESUN is a Chinese high-tech company dedicated to being among the best biodegradable, new material companies in the industry. ESUN is committed to research and promoting the in-depth development of 3D printing products.

PLA (polylactic acid) is a plastic composed of organic plant fiber, such as corn, cassava, or sugar beets. The PLA filament, therefore, is fully biodegradable and eco-friendly. The beauty of PLA plastic is that it is compatible as a composite with other materials to produce a wide array of different colors. The eSteel is part of eSUN’s proprietary metal series. The eSteel filament is produced by infusing micronized stainless steel powder into the standard PLA material that eSUN uses for its other 3D printing filament products.

In addition to being an eco-friendly recyclable material, the eSUN eSteel also has good mechanical properties, offering low shrinkage and warping rates. The eSUN eSteel can be used on either a desktop or industrial 3D printer without a heated platform.


Choose the eSUN eSteel for projects needing a realistic metallic finish. The filament comes on a clear 0.05 kg spool in a vacuum-sealed package. It also comes with a resealable bag with desiccant to enhance storage and maintain freshness.
