The 3D printing process creates the final material or alters the starting material during the process, heightening the need for manufacturers to ensure that their final implant has properties that meet their specifications. Further, as 3D printing technology advances, so too will the materials used in orthopedic implants. In this rapid-fire session, materials companies will present on their materials physical, mechanical and functional properties, clinical benefits and current and future applications.

3D Printable Materials Enabling Next-Generation Regenerative Orthopedic Products

3D printing has become a promising fabrication method for complex tissue engineering applications. One significant limitation, however, has been the lack of biomaterial inks that can be tuned with regard to mechanical properties and bioactivity without compromising “printability.” We have developed a new biomaterial platform that overcomes this limitation and provides a wide range of tailorable and cell-compatible 3D-printable materials with high functionality. In this talk I will present an overview of these new materials, their unique and advantageous properties, examples of their use in medical applications and efforts to translate these technologies into next generation clinical products.

3D Printed OXPEKK Polymers for Cutting-Edge Implants

OXPEKK (polyetherketoneketone) polymer has been used in medical device implants since 2005. In the same polyketone family as PEEK (polyetheretherketone), PEKK offers similar biocompatibility and mechanical characteristics but has additional clinical benefits for use in medical devices. OXPEKK polymer is capable of being 3D printed, which confers design freedom and an inherent surface structure that has been shown to participate in bone fusion while also exhibiting antibacterial characteristics. 3D printed OXPEKK devices have been developed and cleared for craniomaxillofacial, spine and sports medicine applications, and have been providing development engineers and surgeons with an effective alternative to traditional medical device materials. This presentation will discuss the physical and mechanical properties of 3D printed OXPEKK polymer, the functional properties of the 3D printed OXPEKK surface, and will describe both current and future uses in the medical device field.

Managing Risk, Enhancing Safety and Optimizing Economics with Powder Lifecycle Management

A critical challenge associated with 3D printing production is the monitoring of the powder feedstock quality. Several studies have shown that the powder characteristics can significantly impact the printed part properties, and a robust solution is needed to establish full material traceability, enable efficient re-usability of recycled powder and support efficient powder lifecycle management. This presentation will showcase PowderLife and its benefits to additive production. PowderLife is a combination of products that each play a role in enabling higher productivity and quality in 3D printing by providing traceability from starting feedstock to built-component, easy product recall should a defective powder lot be discovered, simple powder inventory tracking, safer powder handling, and comprehensive data collection of key process variables (oxygen, temperature, humidity and pressure).
