3D printed FibreTuff has "bone like" feel and appearance with radiopacity. See picture. The FibreTuff compound used to achieve the radiopacity seen in the CT Scan of the vertebrae. 3D LifePrint evaluated materials they have used for anatomical bone models and found FibreTuff to be more bone like ( HU 400 ) than any other materials presently used today in the medical market. See website www.3dlifeprints.com for more information
FibreTuff has been evaluated by leading service centers for anatomical bone models to replace cadaver work. These 3D printed bone like models have radiopacity, good screw retention with flexibility.
Moreover, these functional anatomical bone models are used at Universities, Medical Centers for clinical evaluations and physicians in preparations for surgery.
Bone gets brittle after being removed from body. Body fluids promote better elasticity as well as impact, FibreTuff is hydrophilic and reacts to moisture very similar. Other 3D printed medical biomaterials like PLA will absorb and store moisture until the composition breaks down. FibreTuff will absorb moisture to a point and promote less brittleness and improve impact. Picture is a calcaneus bone FDM print made with FibreTuff I and a photo of 1st day soaking in water .
These spinal spacers made with FibreTuff medical grade filament are seen under CT Scan with vitamin E capsule. These 3D printed parts were positioned on top of a jug of water to help resemble body fluids. The images have radiopacity where to bone bringing can be identified. Bone will be brighter than the objects made by FibreTuff.
