3D printing material Creality 3D 3301040040 TPU Black 1 kg 1.75 mm

Creality 3D 3301040040 TPU Black is a flexible thermoplastic polyurethane filament designed for FDM/FFF 3D printers. The spool contains 1 kg of 1.75 mm diameter filament in black, providing elasticity, impact resistance and good layer adhesion for parts that require flexibility and durability. The material is suitable for a range of functional prototypes, wearable components and items that need rubber-like properties while remaining printable on compatible Creality 3D printers.

Advantages

TPU Black delivers elasticity and resilience, allowing printed parts to stretch and return to shape without permanent deformation. It offers good abrasion and impact resistance compared with rigid filaments, and its layer bonding reduces delamination in flexible prints. The 1.75 mm diameter ensures compatibility with most direct-drive and many Bowden extruders when printing parameters are adjusted for flexible materials.

Suitable for

• Flexible prototypes and functional parts such as gaskets, seals and vibration dampers
• Wearable accessories and soft grips
• Phone cases, cable organizers and shock-absorbing components
• Small mechanical parts that require impact resistance and elasticity

When it may not be suitable

This TPU filament may not be the best choice for parts that require very high stiffness, sharp dimensional stability at elevated temperatures, or for fine, highly detailed decorative prints where rigid polymers give better surface finish and dimensional precision. Printing very large structural parts that must bear heavy static loads may also be better served by more rigid materials.

Key specifications

• Material type: Thermoplastic polyurethane (TPU)
• Color: Black
• Filament diameter: 1.75 mm
• Spool weight: 1 kg
• Mechanical characteristics: Flexible, elastic, abrasion-resistant
• Compatibility: FDM/FFF 3D printers compatible with flexible filaments

How to use

Load the 1.75 mm TPU filament into a printer configured for flexible materials. Use a moderate nozzle temperature typically in the range recommended for TPU (refer to your printer or filament guide), set a slower print speed than for PLA/ABS to reduce filament buckling, and adjust retraction settings to minimal values or disable retraction if stringing occurs. Use a direct-drive extruder if available for easier handling of flexible filament; Bowden setups can work with careful tuning. Print on a clean build surface; adhesion aids such as a PEI sheet, glue stick or blue painter's tape can help depending on the printer and part geometry.

What to consider before purchase

• Confirm your printer supports flexible filaments and can handle 1.75 mm diameter material
• Plan for slower print speeds and possible adjustments to retraction and extrusion settings
• Check required nozzle temperature ranges and compatibility with your hotend and bed surfaces
• Consider whether elasticity and abrasion resistance meet the mechanical needs of your project

Usage recommendations

For best results, print TPU with a direct-drive extruder at reduced speed, minimal retraction and a nozzle temperature suitable for TPU. Test small calibration prints to fine-tune settings for dimensional accuracy and surface quality before producing functional parts.
