From CAD to Cast Metal in Days, Not Months — Zero Tooling Investment | ITAR Registered | Made in USA | Capability Statement

Turbine Blade Manufacturing, Repair, and Refurbishment

We build new turbine blades and restore damaged ones, including blades in superalloys conventional welding cannot repair. MAR-M247, René 80, and IN100 crack under standard weld methods. Our Scanning Laser Epitaxy (SLE™) process rebuilds them crack-free while preserving single-crystal and directionally solidified grain structure.

Our Turbine Blade Services

Our industrial gas turbine casting service produces new blades in CMSX-4, René N5, René 141, and IN718, with cooling passages cast in rather than machined. First castings ship in 10 to 39 days instead of 12-plus months through traditional tooling. On the repair side, SLE™ restores blades in the alloys most MRO shops decline.

Turbine Blade Manufacturing

We cast new single-crystal, directionally solidified, and equiaxed superalloy blades without tooling. Send a CAD model and specify the alloy. No wax patterns, no core injection dies, and no tooling investment, which matters most on legacy blades where the original tooling is gone. Removing the tooling and wax pattern steps cuts manufacturing cost by up to 50%.

Turbine Blade Repair

SLE™ repairs superalloy blades conventional welding cannot touch. MAR-M247, René 80, and IN100 crack under standard weld methods because of their high gamma-prime content. SLE avoids that mechanism and delivers fully dense, crack-free deposits.

Turbine Blade Refurbishment

We restore worn hot-section blades and airfoils to serviceable condition, rebuilding eroded tips, squealer tips, and damaged geometry while preserving the original microstructure and creep strength.

Single Crystal Blade Repair

Single-crystal blades in CMSX-4, René N5, PWA 1480, and PWA 1484 carry no grain boundaries by design, and that absence is the source of their creep strength at hot-section temperatures. SLE rebuilds damaged sections while continuing the parent crystal orientation, so the repaired region matches the base metal structure.

Superalloy Weld Repair Alternative

If a repair vendor has told you an alloy is not weldable, this is the process built for that answer. SLE laser deposition bonds epitaxially to the substrate and produces crack-free builds with 10% higher microhardness than the cast base metal. We apply it to vanes, nozzles, and shrouds as well as blades.

Blade Damage We Restore

Send us the blade if you are seeing any of the following.

We assess each blade before quoting. Repair timelines are quoted per job, set once we receive the damaged part and finish the assessment. If a part is beyond restoration, we will tell you, and we can quote a new casting instead.

Blade Alloys We Work In

All castings meet applicable ASTM standards and fall within Investment Casting Institute stated ranges. See the full casting grade alloy catalog.

How Blade Repair Works

  1. Assessment. You send the blade drawing, CAD model, or the part itself. We confirm alloy and assess repair feasibility.
  2. Deposition strategy. Our engineers define the thermal parameters and scan pattern for your alloy and geometry.
  3. Laser deposition. Pre-alloyed superalloy powder is deposited by laser onto the prepared blade surface under closed-loop process control.
  4. Epitaxial solidification. The deposit grows from the substrate, continuing its crystal structure rather than forming a separate weld structure.
  5. Finishing and inspection. Post-processing and quality verification to your specification.

Turbine Blade Repair FAQs

Yes. MAR-M247 is one of the alloys our SLE process was developed to handle. It cracks under conventional welding due to high gamma-prime content. SLE produces fully dense, crack-free deposits in it.

Yes. SLE deposits material epitaxially, meaning the new material continues the crystal orientation of the parent blade rather than forming new grains. The repaired section matches the base metal structure.

Conventional welding melts filler into a weld pool that solidifies as a separate structure, often cracking in high gamma-prime superalloys. SLE controls thermal conditions so the deposit grows from and continues the substrate crystal structure, avoiding the cracking mechanism.

Repair timelines are quoted per job. We set the schedule after we receive the damaged part and complete the assessment, because turnaround depends on the alloy, the extent of the damage, and the finishing your specification calls for.

First castings typically ship in 10 to 39 days depending on part complexity and alloy, compared with 3 to 12 months through traditional tooling-based investment casting.

No. Our DirectPour™ process prints the ceramic shell with integrated cores directly from your CAD model. There is no core die, no wax die, and no tooling investment.

Yes. Cores are printed as part of the monolithic shell, so internal cooling passages and film cooling holes are cast in rather than machined afterward.

CMSX-4, René N5, René 142, René 80, René 141, MAR-M247, IN100, IN718, IN625, IN713LC, and Ti-6Al-4V, among others.

Send Us the Blade You Were Told Could Not Be Repaired

We assess repair feasibility on non-weldable superalloys other vendors decline, and we quote new blade castings with no tooling investment. Send a drawing, a CAD file, or the part itself.
