Encyclopedia
TPE (thermoplastic elastomer) is a soft, rubber-like material. Compared to TPU it's even softer and more stretchy, closer to real rubber. It's used for parts that need to stretch, bend and spring back: seals, straps, feet, dampers.
Printing Notes
- Nozzle temperature: 220–250 °C
- Bed temperature: 40–60 °C
- Low print speed (20–30 mm/s) — soft filament buckles at high speed
- Prints best on a direct-drive extruder
The softer the TPE, the harder it is to run on a Bowden setup: the filament compresses inside the tube. Very soft grades (83A and below) really want a direct drive and a slow speed.
TPE is hygroscopic — dry it before printing. Great for functional flexible parts that need high stretch and good shape recovery.
FAQ
TPE is usually softer and more elastic than TPU, closer to rubber. TPU is a bit tougher against abrasion and easier to print. Pick TPE for very flexible parts, TPU for wear-resistant ones.
