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.

Recommended processing conditions.

The nozzle size should be .4 or .5mm with temps at 225- 235C.

The printer bed should be heated at 90 -100C. 

Cooling Fan on for first few layers than turned off 

Recommended layer height .1 - .2mm

Printer oven is desired - temps 80C.

Printing speeds 45 -50 mm/sec

Density or infill is at 90 - 93% infill

Recommend Adhesive or Ultimaker breakaway / PVA
