TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Parabilis Space Technologies is pleased to propose development of a novel additive manufacturing method which enables the use of multiple dissimilar materials in an additively manufactured parent part. This revolutionary process dramatically extends the economic and design advantages of additive manufacturing into areas where either tolerances or available homogeneous materials would otherwise be insufficient.
The use of additive manufacturing has the ability to both reduce part count by enabling innovative designs and reduce design cycle time because of the direct connection between the computer generated geometry and the final part. In addition to expanding the range of possibility for part geometries, additive manufacturing is also unique in the property that the cost of manufacturing increases with the addition, not the removal, of material. Conventional machining is driven by the cost of the time required to remove material. This discrepancy often makes lightweight, minimalistic additive manufacturing designs cheaper than traditionally machined parts. This conveys a significant advantage for aerospace parts where mass is at a premium.
Unfortunately, these revolutionary manufacturing processes are still limited to homogenous powders. This limits their application to parts made from single materials, which, in turn, limits the components on which they can be used or else requires multi-piece assemblies. Aerospace components often have very different temperature, stress, or material compatibility constraints on different regions of the same part or assembly.
The proposed innovation offers a solution to these problems through an innovated method for joining parts into an additively manufactured parent part, creating a functional seal between the materials. This innovation will significantly advance the state of the art of additive manufacturing technology, not only for thrusters and in-space components, but for aerospace and general mechanical parts as well.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed additive manufacturing technology provides significant benefit to a wide range of NASA programs including propulsion, satellite structures, and fluid systems.
The proposed technology promises to benefit a number of NASA missions that require high performance, low cost, innovative propulsion systems. This includes Mars sample return missions, asteroid redirect, and propulsion for any of a number of earth science mission satellites. The ability to include a conventionally machined part in additively manufactured products, include high temperature nozzle inserts, or include insulation into thruster walls, can both increase capabilities and lower cost for all of these programs.
Any NASA satellite program is a strong market for the proposed technology. The proposed innovation allows the use of low weight materials, such as aluminum, for an additively manufactured bulk part with high strength materials included into the printed structure at the sites of applied loads. The high strength material then distributes the load into the low weight part. This technology, when incorporated into satellite bus structures can lower weight, reduce cost, and enhance capability. Satellite buses for deep space missions where propulsion requirements mean that mass and efficiency is highly important can especially benefit.
Fluid components, such as valves and cavitating flow elements which are widely used across NASA programs can also leverage this promising technology.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Commercial satellite propulsion and and launch vehicles can benefit directly from the proposed innovation in much the same way as NASA programs. Innovative nozzle, injector, and thrust chamber designs can lower the cost of launch vehicles, decreasing the cost of access to space.
Beyond the space-related applications, these technical innovations will find a wide variety of applications in terrestrial niches. Specific examples include (but are certainly not limited to):
-An inconel inert in a titanium vessel (under NDA) will improve performance in a series of commercialized items in production for the firearms industry
-Medical devices that could benefit from the combination of weight bearing titanium wear surfaces with a porous ceramic for easier skeletal integration
-Jet engine fuel nozzles manufactured similar to the rocket engine injectors of this SBIR. GE recently introduced additively manufactured nozzles which spurred a $3 billion investment for commercialization of this part
