eSun TPE-83A - 1.75MM Filament 1KG - Black

eSUN TPE-83A (eLastic) Flexible Filament - 1.75 mm, 1 kg - Black

Overview

eSUN TPE-83A is a very soft, rubber-like flexible filament with a Shore hardness of 83A. Printed parts are noticeably softer and more elastic than TPU-95A and eSUN eFlex, with a smooth, skin-friendly matte finish and low surface friction. It is tough and impact resistant, making it a good choice when you need parts that bend, squeeze and spring back.

Key Features

• Shore 83A: softer and stretchier than standard TPU-95A

• High elasticity and toughness; returns to shape after bending or compression

• High impact resistance and durability

• Soft, skin-friendly feel with a matte surface and low friction

Ideal For

• Gaskets, seals and soft feet or bumpers

• Grips, handles and protective covers

• Phone cases, wearables and straps

• Vibration dampers and other flexible functional parts

Printing Tips

• Use a direct-drive extruder with a short, constrained filament path (dual-gear extruders work best). TPE-83A is too soft for Bowden or remote extruders.

• Dry the filament at 55 °C for at least 4 hours before printing, and store it dry (a filament dryer such as the eSUN eBOX helps).

• Print slowly, keep retraction low and disable or minimise retraction if you see jams.

• After long prints, clean the nozzle with cleaning filament; replace the nozzle or throat if feeding becomes unreliable.

• Not suited to the AMS or other automatic material systems; feed it directly to the extruder.
