FibreTuff can be 3D Printed in FDM or SLS. The cellulose fibre thermoplastic composition is user friendly, non temper mental and doesn't require extensive drying like other highly engineered resins. Picture of 3D printed vertebrae made with FibreTuff provided by 3D LifePrint www.3dlifeprints.com
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 breakaway - PVA
3D Printing of FibreTuff filaments can be used on the following 3D Printers
FibreTuff has biomaterial compounds to producing powders for SLS. The FibreTuff replaces highly engineered Nylon and Nylon compounds that are considerable more expensive, are difficult to recycle and lack the necessary "bone like" performance qualities for replacing cadaver work.
The FibreTuff filament will produce prints that are anisotropic, stronger in the Z direction versus X and Y. FibreTuff can be 3D Printed at a very high resolution with extreme accuracy for natural " bone like" qualitie
Depending on your 3D Print infill patterns have been successful for structural yet lightweight parts with 90-92% infill.
These calcaneus bones were 3D Printed using FibreTuff. FibreTuff service centers are able to 3D Print sample bones for you and customers.
3D Printing of FibreTuff compounds for FDM require a heated bed. The heated bed temperatures recommended for the FibreTuff can range from 80 C to 110 C. To adhere the FibreTuff to the heated bed - PVA water soluble breakaway, a glue stick or adhesive sheet is required.
Magigoo is a preferred adhesive https://magigoo.com
