Additive Manufacturing of PEEK and Fiber-Reinforced PEEK for NASA Applications and Custom Medical Devices, Phase I

Metadata Updated: February 28, 2019

There is a significant gap between the properties of materials that are produced using the current 3D printing processes and the properties that are needed to support critical space systems.[HTML_REMOVED] The polyetherimide/polycarbonate (PEI/PC) composite recently demonstrated on the ISS is a significant step forward in development, however, FDM with PEI/PC represents the current practical limits of AM in space due to the temperature requirements to produce other materials

In this Phase I SBIR, AMI, an ISO 13485-Certified (FDA GMP Compliant) Medical Device Developer and Manufacturer, will partner with PSU professors Dr. Michael Hickner of the Center for Innovative Materials Processing through Direct Digital Deposition (CIMP-3D) and Dr. Benjamin Lear, Associate Professor of Chemistry to develop, test, and commercialize a carbon fiber reinforced (CFR) PEEK composite feedstock with improved deposition and strength through focused photothermal polymerization. [HTML_REMOVED]Polymics Inc, a local company with expertise in compounding PEEK, will produce feedstock ready for 3D print.[HTML_REMOVED] The project proposed combines three complimentary approaches to achieve additive manufacturing of precision parts with CFR PEEK:

Formulation addition of carbon microfibers to PEEK filament feedstock to increase overall strength.
Modification of carbon microfibers by impregnating/coating gold nanoparticles to enable photothermally-enhanced bonding to the previous layer.
Incorporation of a focused laser beam adjacent to the print head to initiate localized photothermal heating and localized additional heating directly at the extrusion exit point.
