medical grade filament for 3D printed parts

3D printed skulls made with FibreTuff

3D printed cranio maxillofacial bone models made with FibreTuff medical grade filament

The 3D printing FibreTuff biocompatible materials as filament have a bone like surface texture, as well as appearance and radio density - vertebrae's, skulls, femurs, calcaneus, talus, metatarsal, skull cap, mandible, sacrum. Plus, FibreTuff can be sterilized with standard methods such as Autoclave. 

3D printed microporous FibreTuff PAPC

Annealing FibreTuff for increased strength, performance

The 3D printing FibreTuff medical grade filaments have biocompatible qualities and can be annealed to increase physical performance in some cases beyond 10%. The oven temperatures of 225F / 127C up to 45min will help increase flexibility and strength. 

ISO FibreTuff compounds

FibreTuff Biocompatible compounds for 3D printing made with ISO 13485 Certification

 

FibreTuff has now produced it’s biocompatible compound with ISO 13485 certification. The company will be able to produce filaments for 3D Printing to use in surgical guides and implants. FibreTuff has global recognition to produce the most advanced 3D Printed anatomical bone like models for clinical and pre surgical assessment.

FibreTuff mechanicals

Mechanicals of FibreTuff

The specific gravity of FibreTuff I filament is 1.05 - 1.08 g/cc. This filament for 3D Printing is user friendly and doesn't require extensive drying like other highly engineered Nylon resins. FibreTuff I has proven to be biocompatible with similar properties to Nylon 11 or 12.  Further, printed FibreTuff has twice the strength as bio resorbables like PCL. The FibreTuff is anisotropic, prints are stronger in the Z direction versus X and Y.  

FibreTuff tensile bars

Filament printing with FibreTuff

3D printing in the Z direction is an absolute for bone like construction including radio density. The cortical bone will have 100% infill and cancellous bone being less with different infill patterns available through printer manufacturer. 

3D printed FibreTuff with PVA

FibreTuff Medical Grade filament processing for 3D Printing on Ultimaker 3 and S5

FibreTuff PAPC is biocompatible and needs to be desiccant dried for 8-10 hrs. for optimum 3D printing performance. It can be 3D Printed with various break away materials or support structure polymers to help with the vertical printing in Z direction. Standard  breakaway or water soluble PVA for the Ultimaker 3D Printers can be used.

Recommended processing conditions.

The nozzle size should be .4 or .5mm with temps at 235 - 240C.

The printer bed should be heated at 80 -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  


Please note: A new spool of FibreTuff Medical Grade filament is packaged in a vacuum sealed package with desiccant and  will require some desiccant drying. If you leave spool exposed to elements over a period of time estimated at 3-4 days, moisture pickup is possible and may effect adhesion for layering. An indication of too much moisture is over extrusion or nodules present. It is recommended to desiccant dry spool for 10 hrs before printing.
 

3D printing Hands by VosFox Medical

FibreTuff medical grade filament produced anatomical bone like models that perform like real bone

The 3D printed hand models produced at VosFox medical with FibreTuff showed details having 27 segmented bones attached with wires and pins. The process controls to make the hand included proper drying of FibreTuff before 3D printing. VosFox Medical in the Netherlands is now printing feet with each bone segmented to show realistic construction. see website www.vosfoxmedical.com

Printing FibreTuff

FibreTuff  II medical grade filament requires a heated bed 80 -110 c . You can purchase the biocompatible FibreTuff  II in a 1.75 or 2.85mm size filament. For the FibreTuff II to adhere to the heated bed a glue or adhesive sheet is required. The glue stick recommended is Cube Glue. GeckoTek is a supplier of adhesive sheet for 3D Printing. The nozzle size recommended for FibreTuff  II are .5  with a processing temperature from 220 to 225C. If you use a .4 nozzle, higher heats may be necessary at 230C.  A 3D Printer oven is preferred at temperatures of 80C for maximum efficiency.
