Industrial Gas Turbine Parts | Component Repair & Precision Casting
Advanced manufacturing solutions for critical gas turbine components — 90% energy reduction, 50% cost savings, zero tooling required.
We manufacture industrial gas turbine parts using breakthrough ceramic 3D printing technology that eliminates traditional tooling, compresses lead times from months to days, and unlocks superalloy casting capabilities that conventional foundries cannot match.
Benefits of Industrial Gas Turbine Parts Manufacturing in the United States
Zero Tooling Investment Required
Our LAMP™ technology prints ceramic shell molds directly from CAD files, eliminating $50,000–$200,000+ in conventional tooling costs and delivering three immediate advantages:
90% Energy Reduction with Sustainable Casting
Our DirectPour™ process — validated through the U.S. DOE’s ARPA-E program with GE Vernova — delivers three measurable sustainability gains by eliminating seven of twelve conventional process steps:
Advanced Superalloy Capabilities
Our facility processes the most demanding nickel superalloys for industrial gas turbine hot sections, with demonstrated IGT blade production in DS René 141 with cast-in film cooling holes. Three advanced capabilities set our process apart:
Industry Applications
Power Generation Applications
We manufacture hot gas path components for natural gas, hydrogen-ready, and combined-cycle power facilities — parts that must endure extreme thermal cycling at firing temperatures exceeding 1,000°C. Our tooling-free LAMP™ process serves three critical application areas:
- Turbine blades and nozzle guide vanes in single-crystal and directionally-solidified superalloys for first-stage hot gas path service.
- Gas turbine fuel nozzles and combustion hardware with complex internal geometries and tight tolerances.
- Shrouds, casings, and structural components for base-load and peaking power applications requiring long-term reliability.
Every component is cast to production investment casting standards with full traceability documentation.
High-Value Component Repair
Our SLE™ (Scanning Laser Epitaxy) technology delivers additive repair for damaged superalloy turbine components — restoring original metallurgical specifications without the cracking risks of conventional welding, including on non-weldable alloys like MAR-M247, René 80, and IN100. SLE™ restores mission-critical components across three categories:
- Blade tip restoration and airfoil leading edge rebuilding with deposits exceeding 2mm per pass and matched crystal structure.
- Dimensional restoration of hot gas path components for aerospace and IGT applications with 10% higher microhardness than cast substrate.
- Substrate preparation for thermal barrier coating reapplication, extending service intervals, and reducing replacement part costs.
Fully dense, crack-free deposits with epitaxial continuity make SLE™ the only repair solution for the industry’s most demanding superalloys.
Our Revolutionary Manufacturing Process
Digital Design and Engineering Optimization
Our engineers optimize your CAD models for ceramic shell production — eliminating separate core tooling by integrating all internal features into a single monolithic structure. Three foundational outcomes drive this phase:
Every design review is completed before a single gram of ceramic is printed.
LAMP™ Ceramic 3D Printing Production
Our proprietary LAMP™ process prints fully integrated ceramic shells — with internal cores, cooling passages, and film cooling holes — in a single operation at 15-micron resolution, with no assembly, no tooling, and no wax patterns required. Three performance capabilities set LAMP™ apart:
No other ceramic printing process matches this combination of resolution, surface quality, and production throughput.
Thermal Processing and Metal Casting
Sintered ceramic shells are cast via DirectPour™ — at our Atlanta, GA facility or delivered ready-to-pour to customer foundries — with strict thermal gradient control for single-crystal and DS microstructures. Three quality assurance commitments back every casting:
All castings meet production investment casting standards before leaving our facility.

Frequently Asked Questions
The main parts of a gas turbine include the compressor section (blades and vanes), the combustion chamber (liners and transition pieces), and the turbine section (blades, vanes, shrouds, and nozzle guide vanes). Hot-section components are the most demanding from a materials and manufacturing perspective.
The four main types of gas turbines are aeroderivative gas turbines (adapted from aircraft engines), industrial heavy-duty gas turbines (designed specifically for power generation), micro gas turbines (small-scale distributed power), and gas turbines for mechanical drive applications (powering compressors and pumps in oil and gas).
Rapid Precision Castings manufactures industrial gas turbine components from Atlanta, GA, serving power generation facilities, MRO operations, and turbine service companies nationwide. RPC offers both new component casting through DirectPour™ and SLE™ additive repair for existing components.
RPC's SLE™ (Selective Laser Enhancement) technology uses precision additive restoration to repair turbine blades made from non-weldable nickel superalloys like CMSX-4 and René N5. Traditional welding disrupts the crystal structure of these alloys, making conventional repair impossible. SLE™ deposits compatible material without causing the recrystallization and cracking that traditional welding produces.
A single turbine blade failure can cause millions of dollars in unplanned downtime at a power generation facility. OEM replacement parts often have 6–12 month lead times. RPC's DirectPour™ process delivers replacement castings in as little as 10 days, and SLE™ repair can restore damaged components even faster — dramatically reducing outage duration.
Yes. LAMP™ technology produces ceramic shells with fully integrated cores for complex internal cooling passages, including serpentine channels, film cooling holes, and trailing edge slots. RPC has demonstrated production of industrial gas turbine blades in DS René 141 with single-crystal capability and cast-in cooling features.
DDM Systems (the parent company behind Rapid Precision Castings) has maintained a decade-long collaboration with GE, including a $3.3 million ARPA-E OPEN 2021 award with GE Vernova for "Manufacturing High-Yield Investment Castings with Minimal Energy." This project validated energy savings of up to 90% compared to conventional processes.
Yes. RPC's tooling-free DirectPour™ process is ideal for manufacturing replacement components for legacy and discontinued turbine models where original tooling no longer exists. Parts can be reproduced from existing drawings, 3D scans, or reverse-engineered digital models, eliminating the need to maintain expensive tooling inventories.
RPC uses both air-melt and vacuum-melt investment casting processes for turbine components. For hot-section parts requiring nickel superalloys, vacuum-melt casting is standard to prevent oxidation of reactive alloy elements. RPC supports equiaxed, directionally solidified (DS), and single-crystal (SX) casting processes — covering the full spectrum of turbine component requirements.
Ceramic 3D printing produces molds with geometric precision that eliminates the dimensional variability inherent in traditional shell building. Each printed shell is an exact replica of the digital design — there are no variations from hand-dipped coatings or wax injection tolerances. This consistency translates to tighter dimensional control on finished castings and reduced scrap rates.
