Filament BambuLab TPU 85A 1.75 mm 1 kg with reusable spool — Neon Orange

BambuLab TPU 85A 1.75 mm is a flexible thermoplastic polyurethane filament supplied on a reusable spool in Neon Orange. With a Shore hardness of approximately 85A and a 1.75 mm diameter, this filament is designed for FDM/FFF 3D printers that support flexible materials. The 1 kg spool provides material for printing elastic, wear-resistant parts and comes on a reusable spool to simplify storage and reduce waste.

Advantages

This TPU offers a balance of elasticity and abrasion resistance suitable for functional prototypes and end-use parts. The 85A hardness ensures good flexibility while maintaining dimensional stability for features such as thin walls and living hinges. The reusable spool enables easier handling, organized storage and lowers environmental impact compared with single-use spools. Neon Orange color provides high visibility for parts where contrast or identification is important.

Suitable for

• Flexible functional parts such as gaskets, seals and bushings
• Wear-resistant components and shock-absorbing mounts
• Wearables and ergonomic grips requiring soft-touch surfaces
• Prototypes and small-batch production where elasticity is needed
• FDM/FFF printers configured for TPU filament printing

Key specifications

• Material: thermoplastic polyurethane (TPU)
• Shore hardness: ~85A
• Diameter: 1.75 mm nominal
• Net weight: 1 kg filament per spool
• Color: Neon Orange
• Packaging: reusable spool for storage and transport

How to use

Load the filament into an FDM/FFF printer that supports flexible materials and set print parameters appropriate for TPU 85A. Typical settings include a relatively low print speed, modest retraction or disabled retraction depending on the extruder type, and a print temperature suitable for TPU (refer to your printer and filament guidelines). Use a heated bed or recommended bed surface for improved adhesion when required by the specific print. Ensure the reusable spool is mounted to feed smoothly and avoid tight bends or excessive tension during printing.

Usage recommendations

For best results, use a direct-drive or well-tuned Bowden system with a short gap to minimize filament buckling. Start with conservative speeds and adjust temperature and cooling to optimize surface finish and layer adhesion. Store the filament on the reusable spool in a dry environment to maintain material properties.
