Adhesive required for printing
Bone gets brittle after being removed from body. Body fluids do promote better elasticity as well as impact. FibreTuff PAPC reacts to moisture very similar. Other 3D printed materials like PLA will absorb and store moisture until the composition breaks down. FibreTuff PAPC is hydrophilic, will absorb moisture to a point and promote less brittleness and improve impact. Picture is a calcaneus bone FDM print made with FibreTuff PAPC I and a photo of 1st day soaking PAPC I in water .
The FibreTuff PAPC I has similar properties to Nylon 11 or 12. The specific gravity of FibreTuff PAPC I is 1.08 g/cc. The FibreTuff PAPC has special qualities like radiopacity, screw retention cutting and sawing capability. The applications include anatomical models - foot and ankle, hand and wrist, ear nose and throat. The comparison chart shows significant opportunities to pursue FDM applications in medical market.
Ultimaker s5 Printer had utilized their nylon parameters with FibreTuff filament to print the part shown in the video at RAPID 2019 . The FibreTuff filament showed remarkable adhesion that utilized cellulose fiber in the biomaterial composition. Soon to be released is the FibreTuff filament for the Ultimaker Material Alliance Program.
The Air Wolf printer processing speed 45mm/sec. with FibreTuff filament. The nozzle dia. .5mm at 235c temperature. The heated bed set at 100c. No oven chamber required.
These anatomical models 3D Printed with FibreTuff PAPC II show superior bone like qualities compared to the competition.
These filters have improved structural integrity with absorbent qualities for drug delivery
This 3D Print was generated from a CT Scan and transferred to 3D Printer. The 3D Print was made with FibreTuff filament had "bone like" qualities .
The 3D Printed medical devices with FibreTuff PAPC show significant improvement in both chemical and thermal properties . The FibreTuff PAPC can be 3D Printed into 70um to 100um porous filters with a wide processing window and no visible degradation of cellulose fibers when printed at recommended temperatures.
FibreTuff PAPC II has passed Cytotoxicity and Skin irritation tests and USP Class VI testing for temporary implants performed by NAMSA a regulatory approved testing
company for medical devices and implants. PAPC II has certification papers available.
FibreTuff PAPC II used in X ray and CT Scan at Toledo Clinic.
FibreTuff PAPC II filament requires a heated bed for 3D Printing on a FDM Printer. You can purchase FibreTuff PAPC II in two sizes, a 1.75 of 3.0mm. For the FibreTuff PAPC II to adhere to the heated bed on the 3D Printer, a glue or adhesive sheet is required. The glue stick recommended is Cube Glue. GeckoTek is a supplier of adhesive sheet for heated beds to 3D Print the PAPC II. The type of heated bed recommended for PAPC is EZ - Stik Hot Build Plate. The nozzle size recommended for FibreTuff PAPC II are .5 with a processing temperature from 220 to 225C. If you use a .4 nozzle, higher heats may be necessary at 230C. The heated bed temperature recommended is 95C. A 3D Printer oven is preferred at temperatures of 80C for maximum efficiency. FibreTuff PAPC II filaments will have an inherent moisture due to the hydrophilic nature of the composition. It is recommended that the FibreTuff PAPC be kept in a sealed bag after use.
