TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Cornerstone Research Group Inc. (CRG) proposes to continue efforts from the 2015 NASA SBIR Phase I topic H14.03 ?Reversible Copolymer Materials for FDM 3D Printing of Non-Standard Plastics.? CRGs offers NASA the ability to reprocess space mission waste packaging plastics as an In-Situ resource for in space manufacturing via Fused Deposition Modeling (FDM) type 3-D printing of replacement tools, parts, and devices. This innovation is enabling for space exploration, the application of CRG?s reversible thermoset (RVT) polymers combined with a plastic recycling, blending, and extrusion process will allow current and future packaging materials to be processed into a copolymer blend filament suited to FDM 3-D printing system. This approach offers two implementation routes including; (1) An RVT additive that can be combined with existing waste packaging during a reclamation process to produce 3-D printer filament and (2) A RVT based replacement packaging material that can be directly reclaimed into 3-D printer filament. The material properties of 3-D printer filament from the RVT-based reclamation process can be tuned for mechanical performance (stiffness, flexibility) by adjusting the blend ratios of reclaimed waste packaging:RVT. This will provide NASA with a means to generate 3-D printer feedstocks with varying mechanical performance from on-hand packaging plastics without the need for separate 3-D printer material payloads. CRG has already demonstrated the efficacy of RVT additive in reclamation of NASA?s packaging materials in Phase I by producing a co-polymer blend of RVT with NASA packaging, producing a FDM printer filament with the reclaimed packaging, and successfully 3-D printing the resulting reclaimed packaging material. CRG?s proposed approach to further develop thermally-reversible polymer materials to reclaim NASA?s packaging will provide a material and processing technology readiness level (TRL) of 5 at the conclusion of the Phase II effort.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Supporting NASA's Human Exploration and Operations Mission Directorate (HEOMD) and the MSFC, this project's technologies directly address requirements for solutions to recycling on-board plastics materials into 3-D printable formats for low-earth orbit and space flight additive manufacturing systems. This project's technologies offer a means to take on-board non-critical plastics, such as packaging materials, and reclaim these objects for 3-D printing of needed custom parts without requiring an additional mission payload of 3-D printing feedstock.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Department of Defense systems would derive benefits from this technology, including rapid prototyping and additive manufacturing of complex, low-run number, and advanced design parts. Prime defense contractors could find use of an enabling technology allowing 3-D printing of new and exotic polymeric materials or polymeric composites previously thought incompatible to FDM-type processing. Human systems focused solutions would have the ability to additively manufacture custom components for personnel equipment, such as softer elastomeric materials for integral user-custom equipment.
This technology's attributes for improving the compatibility of polymers to 3-D printing systems would yield a high potential for private sector commercialization for 3-D printer manufactures, significantly increasing the materials properties available in the feedstock. Such companies could dramatically expand the thermoplastic raw materials available to consumers, and potentially be able to produce materials with custom mechanical performance on-demand.
