Rocket Engine Parts & High-Performance Alloys
We produce precision spacecraft components and satellite castings through our patented LAMP™ ceramic 3D printing and additive manufacturing technology, serving aerospace manufacturers, defense primes, and launch vehicle programs across the United States — from rocket engine parts and rocket propellant tanks to thermal control hardware and structural components, with zero tooling investment required.
Benefits of Spacecraft Component Manufacturing in the United States
Zero Tooling Investment Required
Traditional foundries require $50,000–$200,000 or more in hard tooling before a single part can be cast. Our ceramic 3D printing produces shell molds directly from CAD files — eliminating tooling costs. Key advantages include:
Accelerated Development Cycles
Traditional investment casting takes 52–80 weeks. Our DirectPour™ process delivers first parts in as little as 10 days — a 10x lead time improvement that accelerates engine design validation for combustion chambers, rocket engines, and space shuttle components. Cycle-time benefits include:
Space-Qualified Materials & Precision
We cast vacuum-melt nickel superalloys — single-crystal, directionally-solidified, and equiaxed — for rocket engines and spacecraft propulsion systems, processed to AMS 2175 Class 1 Grade A. Every casting is dimensionally verified for weight, surface, and tolerance specifications. Precision capabilities include:
Industry Applications
Rocket Component Manufacturing
We produce precision component castings for advanced rocket engine and turbine engine programs. These propulsion systems burn cryogenic propellants and operate under extreme thrust conditions — placing exceptional demands on every cast component across the engine cycle. Our LAMP™ technology enables the complex internal geometries, high-pressure combustion chamber features, and integrated cooling channels these castings require. Rocket component capabilities include:
- Combustion chamber and turbopump housing castings in nickel superalloys.
- Complex internal cooling channel geometry integrated directly into the ceramic shell.
- Both air-melt and vacuum-melt alloy processing for solid rocket motor components and propellant system parts.
High-Performance Alloys
Spacecraft, rocket engines, and jet engines operate at temperature extremes that only high-performance vacuum-melt superalloys can survive. We cast in CMSX-4, René N5, René 141, René 142, MAR-M247, IN718, IN713LC, and Inconel 625 — spanning equiaxed, directionally-solidified, and single-crystal microstructures for the most demanding turbine engine and space environments. Alloy capabilities include:
- Single-crystal CMSX-4 and René N5 for maximum thermal fatigue resistance.
- Directionally-solidified René 141 and René 142 for turbine blade and vane applications.
- MAR-M247 and IN100 for equiaxed high-temperature structural castings.

Our Spacecraft Component Process
Digital Design & Engineering
Every engagement begins with your CAD model and a detailed engineering review. Our team uses casting simulation software to analyze fill patterns, solidification behavior, and thermal gradients — optimizing shell geometry for your specific alloy and application. Engineering steps include:
LAMP™ Ceramic 3D Printing
Our Large Area Maskless Photopolymerization (LAMP™) process builds fully integrated ceramic shell molds directly from CAD — eliminating wax patterns, multi-piece tooling, and manual shell-building steps. The result is faster iteration with no tooling investment. Print process highlights include:
Precision Casting & Quality Assurance
Following binder burnout and sintering, the ceramic shell is poured — on our casting floor or at a qualified partner foundry — in vacuum or air-melt alloy systems. Every casting then undergoes a fully documented inspection sequence before shipment. Quality assurance steps include:
Every flight-critical part ships with complete traceability documentation and AMS-compliant material certifications.

Frequently Asked Questions
Spacecraft components include propulsion system hardware (engine nozzles, injectors, turbopumps), structural elements (frames, brackets, mounting hardware), thermal management systems, and guidance and control mechanisms. Many of these require precision-cast superalloy or high-performance metal parts.
Spacecraft materials include nickel superalloys (Inconel 625, 718, MAR-M247) for propulsion and high-temperature applications, aluminum alloys for structural and lightweight components, stainless steels for hardware and fittings, and specialty alloys selected for specific thermal, mechanical, or corrosion requirements.
Spacecraft are manufactured through a combination of precision machining, investment casting, additive manufacturing, and composite fabrication. Critical metal components like turbopump housings and engine injectors are typically investment cast to achieve complex internal geometries and stringent material properties.
Rapid Precision Castings produces spacecraft components from its facility in Atlanta, GA, serving space industry customers at major launch hubs including Cape Canaveral, Houston, Southern California/Mojave, and Colorado Springs. RPC's DirectPour™ process delivers space-grade castings in days rather than months.
New Space companies like SpaceX, Blue Origin, and emerging launch providers operate on aggressive development schedules that demand rapid design iteration. RPC's DirectPour™ process enables engineers to receive functional castings in the production alloy within 10 days — allowing multiple design iterations in the time traditional foundries need for a single first article.
Yes. LAMP™ technology excels at producing cast-in cooling features for propulsion components, including film cooling holes, serpentine internal passages, and branching channel networks. These features are critical for rocket engine thermal management and are produced without the multiple sets of core tooling traditionally required.
RPC casts the advanced nickel superalloys required for space propulsion, including Inconel 625 and 718 for general high-temperature applications, IN100 and MAR-M247 for extreme conditions, and CMSX-4 and René N5 for single-crystal turbopump components. Vacuum-melt processing is standard for these alloys.
Space industry programs frequently require small quantities of highly complex parts — sometimes just one or two units for a unique mission. Traditional casting tooling costs of $50,000–$500,000 per design make small-batch production economically impractical. DirectPour™ eliminates tooling entirely, making single-unit and small-batch space-grade castings cost-effective.
RPC operates a fully domestic manufacturing facility in Atlanta, GA, providing U.S.-based supply chain security for sensitive space and defense applications. This eliminates ITAR compliance risks associated with international manufacturing and ensures direct oversight of quality processes for mission-critical castings.
RPC's capabilities align with the needs of major space contractors and New Space companies requiring rapid-turnaround precision castings in space-grade superalloys. The company's patented technology addresses the specific pain points of aggressive launch schedules, iterative design cycles, and the need for complex geometries that traditional foundries cannot efficiently produce.
