ELEGOO TPU Filament 1.75mm 1kg spool 🖨

This black TPU filament is a flexible 3D printing filament that brings elasticity and impact resistance to functional prints, suitable for wearables, gaskets and flexible prototypes. It offers high stretch and return properties, making it easier to print parts that need to bend or absorb shocks according to the manufacturer.

Key Points

This spool stands out for its stretchability and resilience, with a Shore hardness that balances firmness and flexibility. It feeds smoothly in most common 1.75 mm FDM printers and is vacuum sealed to protect against moisture during storage. 🧵

Printing with flexible materials can require slower print speeds and careful retraction tuning to avoid oozing and stringing. For many users, reducing print speed and using a direct-drive extruder helps achieve cleaner results. 🛠️

The filament is marketed as having consistent diameter and minimal bubbles, which reduces the likelihood of under-extrusion and sudden clogging. Consider drying the filament before long print jobs, as the manufacturer recommends.

Usage Recommendations

Start with conservative settings and adapt from there. A lower print speed and higher extruder temperature within the filament’s recommended range usually improves layer adhesion for flexible prints. Use a brim or skirt for small contact areas to improve bed adhesion, and avoid excessive retraction distance which can cause jams in Bowden setups. For parts that will face repeated bending or impact, test small samples to fine tune infill and wall thickness.

When handling and storing, keep the spool in a dry place and use desiccant packs if you open the vacuum seal for extended periods. While the filament is described as resistant to impact and stretching, consider that very high-load applications may still require tougher engineering elastomers.
