Who it fits

Key specs explained

1.75mm Diameter, ±0.03mm Accuracy

This dimensional tolerance ensures the filament fits standard FDM printers. You get consistent extrusion without clogs or under-extrusion. The tight variance helps maintain print quality across long jobs. Compare this to cheaper filaments with wider tolerances that may jam your hotend. This precision is vital for detailed flexible parts that require reliable layer bonding.

Shore 90A Hardness

This rating defines the material's flexibility and firmness. A 90A TPU offers a balance between softness and structural resilience. You can bend printed parts without breaking them, making it ideal for phone cases or gaskets. It is softer than rigid PLA but holds its shape better than very soft TPU variants. This hardness suits everyday wear and tear applications.

0.75kg Spool Weight

This weight determines the total volume of material available. A 0.75kg spool is suitable for small to medium-sized flexible prints. You get enough filament for prototypes or single functional parts without committing to a larger bulk spool. Consider this against 1kg or 2kg options if you plan extensive printing. The size fits standard spool holders on most desktop 3D printers.

High-Speed Printing Capability

The product claims to print up to three times faster than ordinary TPU. This efficiency reduces job times for flexible materials, which are typically slow. You benefit from quicker turnaround for prototypes or functional items. This feature is useful if you frequently print flexible parts and want to save time. Compare this to standard TPU filaments that require slow, cautious printing speeds.

Design and Build Overview

The Polymaker PD02001 is a flexible thermoplastic polyurethane spool. According to the listing, it offers strong wear, oil, and aging resistance. The 90A Shore hardness provides high elasticity. You can expect parts that withstand severe collisions and daily wear. This material choice suits robotics and fashion projects where durability matters.

The spool holds 0.75kg of filament. The physical dimensions are 7.87 inches wide, 1.77 inches high, and 7.87 inches long. The total weight is 1.65 pounds. This compact layout fits standard FDM printers. The 1.75mm width with ±0.03mm accuracy ensures broad compatibility. You get consistent extrusion without clogs or under-extrusion. The tight variance helps maintain print quality across long jobs.

Polymaker highlights a smooth finish and strong layer adhesion. The listing states the filament prints up to three times faster than ordinary TPU. This speed balance supports efficient production. The black color is listed as Hex Code #16161a. You can choose from other colors in the broader lineup. The design prioritizes reliability and ease of use for flexible applications.

Setup and Everyday Use

Loading this Polymaker TPU into your printer is straightforward. The 1.75mm diameter and ±0.03mm dimensional accuracy ensure it fits nearly all standard FDM 3D printers. You do not need specialized hardware to run it. The tight tolerance helps prevent clogs and under-extrusion, which are common issues with flexible materials. This precision allows for consistent extrusion throughout your print job.

The listing states this filament prints up to three times faster than ordinary TPU. This high-speed capability means you can complete flexible parts more efficiently. You get enhanced efficiency without sacrificing the balance of softness and resilience. The 90A Shore hardness provides strong layer adhesion. This results in smooth finishes and high-quality interlayer bonding. You do not need to adjust your settings drastically if you already print standard PLA or ABS.

Daily use involves handling parts that withstand severe collisions and daily wear. The material offers strong wear, oil, and aging resistance. You can trust these prints for robotics, fashion projects, or functional flexible applications. The 0.75kg spool size is manageable for most desktop printers. You can choose from various colors, including black, white, and bright options. This variety lets you match aesthetic preferences while maintaining durable performance. The filament is designed to handle the rigors of everyday use. You get reliable results with minimal troubleshooting. The combination of speed and durability makes this a practical choice for regular printing tasks.

Before You Buy This TPU

You need an extruder with good grip to handle this flexible filament. Direct drive systems work best. Bowden setups may struggle with feeding. Check your printer’s maximum speed settings. Polymaker claims up to three times faster printing than standard TPU. You should still start slow. Verify your hotend can reach the required temperature for TPU90. The 0.75kg spool fits standard holders. Ensure your printer’s build volume suits your project size. Keep the spool sealed when not in use. TPU absorbs moisture, which affects print quality. Store it in a dry box. This option sits alongside rigid plastics in your toolkit. It adds flexibility to your capabilities. Choose it for parts that bend or absorb impact. Compare it with the TPU95 variant if you need more rigidity. The 90A hardness offers a middle ground. It balances softness with durability. This makes it suitable for robotics and fashion projects.

Check before you buy

• Verify your printer has a direct drive extruder for reliable feeding.
• Check that your hotend reaches the specific temperature for TPU90.
• Ensure you have a dry storage box to prevent moisture absorption.
• Confirm your build volume fits the flexible parts you plan to print.
