3D Printer Data/Information for FibreTuff
Injection Molding FibreTuff
Without a reinforcement and/or filler FibreTuff has a Tensile Strength at yield ASTM D638 of +5,000 psi. With a glass fiber reinforcement, the Tensile Strength can be + 7,000 psi. This Tensile Strength value is present at 42%, 34% and 28% wood flour. These properties show a linear plot versus existing technology which declines in Tensile Strength with increase in wood flour loading levels.
- Flexural Modulus ASTM D790 is above 600,000 psi for 42% wood flour
- Flexural Strength ASTM D790 +8,000 psi
- Heat deflection temperature +280 F at 64 psi
- Minimal moisture uptake SAE J315 is .04%
3D Printing FibreTuff
FibreTuff can be 3D Printed with various break away materials or support structure polymers to help with the vertical printing in Z direction. Standard breakaway for the Ultimaker 3D Printers can be used.
