Hell3D Filament is one of the best grades filaments available. Please note that it is branded as Mambawire for the South African market.
Thermoplastic polyurethane (TPU material) is a flexible, abrasion resistant thermoplastic. TPU filament has a number of features, making it a great choice for a wide range of uses. 3D printed parts with TPU are durable and have the ability to withstand ambient temperatures of up to 80 degrees Celsius. It is resistant to abrasion, oil, chemical and wearing, which makes it perfect for use in industries such as the automotive industry. Printed parts of TPU are also resistant to low temperatures, which means that it does not become brittle and difficult to work with.

Printing tips for TPU:
- Optimize the feed rate by printing at lower layer heights in the 0.1mm – 0.2mm range. The lower layer height requires less plastic, so it allows your extruder to use a lower feed-rate, relieving the burden on the filament.
- Try to avoid using rafts with flexible materials, as the base layers of the raft have higher extrusion rates which may create issues.
- If you are designing a flexible part that needs to fit on top of another object, try using a negative tolerance between the parts so that the flexible part will need to stretch to fit over the other object snugly.
