When engineering components require both long-term impact resistance and maintained flexibility, material selection presents a significant challenge. Traditional rigid materials often lack necessary elasticity, while softer alternatives may fail under demanding conditions. BEDROCK 3D's newly developed TPU 64D filament offers a solution to this engineering dilemma.
The BEDROCK 3D TPU 64D represents a high-durometer thermoplastic polyurethane filament with a Shore hardness of 64D, ranking among the stiffest in flexible material categories. This formulation achieves an optimal balance between rigidity and controlled elasticity, making it particularly suitable for industrial applications requiring both durability and deformation capacity.
The material demonstrates exceptional wear and scratch resistance while maintaining physical properties in harsh environments. Its performance remains stable in low-temperature conditions, offering superior impact resistance, cushioning properties, and resistance to oils, greases, oxygen, and ozone. These characteristics position TPU 64D as a viable alternative for manufacturing industrial components such as tools, jigs, and fixtures, potentially replacing conventional ABS materials.
Despite its enhanced rigidity compared to standard TPU filaments, TPU 64D maintains good printability across both direct-drive and Bowden-style 3D printers. The material supports soluble support structures (such as BVOH Bedrock support) and dual-extrusion techniques for producing complex geometries. Water-soluble support materials enable clean, efficient post-processing without surface residue, streamlining production workflows and reducing costs.
Manufactured under rigorous quality control protocols, BEDROCK 3D TPU 64D ensures consistent reliability and cost-effectiveness for industrial applications. The material meets stringent performance requirements for manufactured components.
Key technical parameters include:
| Category | Parameter | Value |
|---|---|---|
| General Information | Material | TPU/TPE |
| Density | 1.19 g/cm³ | |
| Filament Diameter | 1.75 / 2.85 mm | |
| Print Temperature | 230-255°C | |
| Bed Temperature | 40-60°C | |
| Recommended Speed | 30-60 mm/s | |
| Mechanical Properties | Tensile Strength | 37 MPa |
| Elongation at Break | 399% | |
| Hardness | Shore 64D | |
| Impact Resistance | No break (ISO 180) |
For optimal performance, recommended printing parameters include nozzle temperatures between 230-255°C, print speeds of 30-60 mm/s, and a heated glass bed at 40-60°C. Printing in a passively heated enclosed chamber is advised to ensure material performance and print quality. While compatible with Bowden systems, direct-drive extruders are preferred to minimize potential feeding issues.
Proper storage is essential for maintaining print quality. TPU 64D should be kept in dry conditions before, during, and after printing. Original packaging with desiccant, vacuum-sealed bags, or smart filament containers provide effective moisture protection. For moisture-saturated filament (evidenced by bubbling or surface defects), drying at 70°C for five hours in a convection oven or vacuum dryer is recommended.
This advanced material expands possibilities in industrial 3D printing, offering engineers and designers new options for functional component production.
