Polyamide Polyolefin and Cellulose (PAPC) filaments produce 3D printed bone replacement, meshes, lumbar spacers, hearing aides, & foot orthotics.
FibreTuff PAPC filament is comprised of FDA compliant advanced biomaterial compounds including cellulose fiber for producing 3D Printed parts in the medical industry. PAPC has already passed NAMSA Class I testing governing cytotoxicity and skin irritation, as well as USP Class VI testing for Class II, and eventually Class III 3D Printed medical devices and implants. PAPC’s strength is ideal for medical, dental, and veterinary applications, as well as industrial, commercial, and aerospace.
Biocompatible: PAPC is bioabsorbable, meaning living tissue and bone will absorb and adhere to it.
Non Toxic: PAPC is non bioresorbable and does not dissolve inside the body or leech harmful compounds into the bloodstream.
Desktop FDM Compatible: PAPC II rivals PEEK in strength to weight ratio but prints at 230℃ making it compatible with most desktop FDM printers.
Using PAPC 3D Models for Orthotics:
FibreTuff PAPC provides superior anatomical bone models with Radiopacity for femurs, calcaneus, talus, metatarsal, skull cap, mandible, sacrum, etc.
Pre-surgical simulation, assessment, training & planning.
Practice drilling through bones using models 3d printed to match patient specific anatomy.
Practice putting implants in place, including exactly where and how deep to drill or cut bone with the proper insertion angle.
Improved surgical outcomes for patients.
Reduced operation times.
Increased effectiveness of medical/surgical education and training.
Ability to drill, saw, screw, machine, and laser cut.
Anatomical accuracy of model in respect to patient.
Realistic mechanical properties for cortical and inner bone.
A virtual reality simulator for orthopedic basic skills:
FibreTuff PAPC II testing for medical use:
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.
FibreTuff PAPC II biomaterials for anatomical models and medical devices:
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.
High Strength or Pliability: Our PAPC filaments are produced in multiple formulations for applications requiring high impact or compression strength, or a high degree of flexibility.
Strong & Affordable: PAPC is a cost-effective alternative to high-performance materials such as PEEK and is recommended for high strength applications where FDA compliant ingredients are required. PAPC has high heat resistance and excellent strength to weight ratio. 3D printed parts have withstood 6,000psi. compressive strength.
Desktop FDM Compatible: While PEEK requires printing temperatures above 350℃, PAPC formulations will print at temps ranging from 210℃ to 260℃
Versatile: Temporary uses include mesh or sutures for surgical use, 3d printed casings for spinal stimulation devices, or even as a scaffold to help grow bones.
Sterilization: PAPC parts utilize standard sterilization methods Autoclave and Gamma irradiation.
Radiopaque: PAPC is visible to X-Ray and MRI imaging which provides key advantages over both PEEK and metal implants. PEEK is invisible to radiology and the only way to examine an implant if a patient is experiencing discomfort due to potential fit issues is through surgery. Patients with metallic implants cannot undergo MRI scanning and metals leech toxic compounds into the body over time as well.

Coating PAPC: A range of options yield improved adhesion for better part strength as well as adhesion of specialized coatings.
Circuitry: PAPC’s adhesive properties support advanced printing technology for printing electronic circuits allow 3D printed circuits to be placed on or embedded into 3D printed PAPC parts. These circuits may contain sensors for monitoring environmental or mechanical conditions experienced by an implant or other device, which can help to monitor the health of both the patient and the device and to warn of possible problems. These sensors could measure temperature, pressure, motion and other factors that would send the information to a doctor. A sensor could also measure balance and equilibrium on a person that has orthopedic surgery or monitor a wound for infection by measuring temperature changes.
Post Processing: PAPC parts can be laser cut or machined; e.g. drilling, sawing, turning milling, etc., without the need for annealing. Hydrophobic ingredients also lower moisture uptake and reduce drying time.
PAPC compounds have a low specific gravity .99 - 1.04 based on ASTM D792-13 testing and water absorption < .24% based on ASTM D570-10.
The melt flow rate is approx. 15-20 grams per 10 min. per ASTM D1238-13.
