Thermoplastic TPU-95A 3D Printer Filament Polmask PD03001 Black 1.75 mm 1 kg

Thermoplastic TPU-95A Polmask PD03001 is a flexible filament formulated for FDM/FFF 3D printing. This black 1.75 mm filament on a 1 kg spool offers elasticity and abrasion resistance suitable for parts like gaskets, seals, wearable prototypes and flexible housings. The TPU95-HF variant is a high-flow material derived from Covestro’s Addigy family, designed for reliable feeding and consistent extrusion and enabling higher printing speeds when used with the appropriate printer setup.

Advantages

PolyFlex™ TPU95-HF provides high flow characteristics that allow faster printing compared with standard TPU grades when processed correctly. It delivers good elasticity and wear resistance in final parts, and the 1.75 mm diameter on a 1 kg spool is compatible with common desktop FDM printers. The filament is formulated for steady extrusion and reliable feeding to reduce print failures related to inconsistent flow.

Suitable for

• Flexible seals and gaskets
• Wearable prototypes and soft components
• Flexible housings and protective covers
• Small flexible mechanical parts requiring abrasion resistance

When it may not be suitable

This TPU filament is not appropriate for applications requiring rigid or load-bearing structural parts because of its elastic nature. Very large prints or parts that need extreme dimensional stability under load may perform better with a more rigid engineering thermoplastic.

Key specifications

• Material: Thermoplastic polyurethane (TPU), high-flow variant
• Shore hardness: ~95A (TPU-95A)
• Filament diameter: 1.75 mm
• Spool weight: 1 kg
• Color: Black
• Recommended printing temperature: 200–220 °C
• Recommended build plate temperature: 25–50 °C
• Printing speed range: 40–100 mm/s (100+ mm/s possible on direct drive with tuned setup)

How to use

Load the 1.75 mm filament into your printer following the manufacturer’s loading procedure. For best results use a direct drive extruder mounted close to the hot end; indirect drive printers can work but require adjusted retraction settings. Set nozzle temperature between 200 and 220 °C and bed temperature between 25 and 50 °C. Enable part cooling fan as indicated. Adjust print speed within 40–100 mm/s; higher speeds are achievable on a well-tuned direct drive system. Use retraction settings appropriate to your extruder type: around 3 mm retraction at 40 mm/s for direct drive, and around 6 mm at 60 mm/s for indirect drive. Dry filament at 70 °C for 8 hours only if moisture absorption is suspected.

What to consider before purchase

• Printer type: direct drive recommended for high-speed printing
• Intended part function: elasticity and abrasion resistance, not for rigid structural loads
• Compatibility with your printer’s hot end temperature range
• Storage and drying needs if filament has absorbed moisture

Usage recommendations

For high-speed prints with PolyFlex™ TPU95-HF use a direct drive extruder, tune retraction and print speed, and ensure filament is dry. Test small samples when changing speeds or retraction settings to optimise print quality and reduce stringing.
