Comgrow TPU Filament 1.75mm 95A Black - Flexible 2kg Total

In this review the Comgrow TPU filament is evaluated as a practical, soft flexible material for users who need rubber-like performance from an FDM printer. It is best for hobbyists and designers making phone cases, wearables, or protective covers where bendability and impact recovery matter most. The single biggest reason to buy is the filament's balance of softness and consistent extrusion: with a 95A Shore rating and precise 1.75mm diameter it prints reliably for short to moderate runs on compatible machines.

Key Features

• Material: Premium TPU delivers flexible prints with a rubber-like feel suitable for parts that must bend and recover.
• Diameter precision: 1.75mm with dimensional accuracy of +/- 0.02 mm helps maintain steady extrusion and reduces under- or over-extrusion during prints.
• Durometer: 95A Shore hardness provides good bendability while keeping structural integrity for functional prototypes and end-use parts.
• Spool size: Each spool is 1kg (2.2 lbs), giving enough material for multiple parts or longer runs without frequent swaps.
• Print settings: Recommended 210-230C printing temperature range helps users dial in layer adhesion and surface finish for consistent results.
• Compatibility: Works with most FDM printers that have direct drive extruders and can handle flexible materials for reliable feeding.

Who It's For

The filament is aimed at makers, small-scale prototypers, and hobbyists who want a soft, impact-resistant material for parts like phone cases, gaskets, and wearable prototypes. Those with printers that support flexible filaments and direct drive extrusion will get the cleanest results and fewer feeding issues.

It is less appropriate for users who need extremely long continuous prints beyond a few hours without reloading, or for setups with Bowden-style extruders that are not tuned for soft filaments; such users should consider filaments specifically formulated for Bowden systems or different hardness ranges.

Pros & Cons

Pros

• Soft 95A durometer produces flexible, durable parts with good compression recovery.
• Precise 1.75mm diameter and +/- 0.02 mm tolerance promote consistent extrusion and layer adhesion.
• Standard 1kg spool size provides a practical amount of filament for most hobby projects.
• Recommended 210-230C range is easy to reach on most consumer FDM printers for predictable prints.

Cons

• Some customers report mixed filament quality, so occasional spool-to-spool variation is possible.
• Not ideal for printers without direct drive setups unless users retrofit or tune their extrusion system for flexible filaments.

Our Verdict

The Comgrow TPU filament is a solid choice for anyone needing soft, impact-resistant prints from a 1.75mm feedstock.

Frequently Asked Questions

Will this work on my FDM printer?
It works on most FDM printers that can print flexible materials, especially those with direct drive extruders; Bowden setups may require tuning.

What temperature should I print at?
Use the recommended 210-230C range and adjust slightly for your hot end and part geometry to improve layer adhesion and surface finish.

Is the filament consistent spool to spool?
Most users report consistent extrusion and good print quality, but customer feedback indicates occasional mixed filament quality, so inspect new spools before long prints.
