DDM Systems touts ceramic 3D printing for gas turbine casting shortages

DDM Systems says its ceramic 3D printing platform can speed up investment casting for gas turbine hot-section parts as AI data center power demand strains turbine supply chains. The company is pitching the technology as a way to cut lead times, reduce tooling, and ease a backlog that could delay new power capacity through 2030.

Why it matters: - AI data center buildouts are pushing gas turbine demand into a supply chain that already has multi-year backlogs. - Precision-cast hot-section parts, not final turbine assembly, are the main constraint on new turbine output. - DDM Systems is positioning ceramic 3D printing as a way to speed delivery of the turbine components needed for behind-the-meter and grid power projects.

What happened: - DDM Systems announced that its patented LAMP, or Large Area Maskless Photopolymerization, technology can directly address the casting bottleneck limiting gas turbine production for AI data center power infrastructure. - The Atlanta-based company made the case around July 28, 2026, tying its pitch to hyperscaler power demand and turbine supply shortages. - DDM Systems said its Digital Foundry platform is built to serve turbine OEMs and energy companies looking for alternatives to conventional casting.

The details: - GE Vernova's gas power backlog plus slot reservations rose from 50 GW to 100 GW during 2025, with delivery slots stretching seven years into the future. - Siemens Energy nearly doubled gas turbine unit sales from 100 in fiscal 2024 to 194 in fiscal 2025. - Mitsubishi Heavy Industries is doubling capacity on a $35.6 billion energy backlog. - The Stargate project represents $500 billion and 10 GW of planned capacity. - Meta's Hyperion campus targets 7.46 GW. - Microsoft signed a 1.4 GW gas LOI in West Virginia. - xAI Memphis deployed 60 turbines. - Crusoe ordered 29 LM2500XPRESS aeroderivatives. - A single set of 40 single-crystal turbine blades costs upward of $600,000 and can take 60 to 90 weeks to produce using conventional methods. - DDM says LAMP uses patterned UV light to cure a photosensitive ceramic slurry layer by layer, producing investment casting shells with integrated cores directly from CAD files. - The company says the process eliminates 7 of 12 traditional casting steps and removes the need for wax pattern tooling. - DDM's production-scale LAMP platform has a 24-inch by 24-inch by 24-inch build volume and can produce 36,000 cubic centimeters of 3D printed ceramic shell molds per day. - DirectPour is DDM's casting service that takes a CAD model and specified alloy, then handles shell design, 3D printing, thermal processing, and foundry coordination. - DDM has demonstrated casting capability in CMSX-4, IN 718, IN 713C, IN 738LC, René 141, René 80, MAR-M247, and IN100. - Dr. Suman Das said the company developed LAMP over 15 years with DARPA and ARPA-E funding to address manufacturing bottlenecks like the current turbine casting shortage. - Das said DDM can produce ready-to-pour ceramic shells in days rather than months. - The company says LAMP uses 4.1 million individually addressable UV beams and achieves 15-micron resolution across the full build volume. - DDM says its SLE, or Scanning Laser Epitaxy, process can produce single-crystal, directionally solidified, and equiaxed superalloy structures directly from powder. - The company says SLE can process non-weldable alloys such as MAR-M247, Rene 80, and IN100. - DDM says its technology has been validated through more than $8 million in federal contracts from DARPA, ARPA-E, the Department of Energy, and the Department of Defense. - The company said an ARPA-E OPEN 2021 award of $3.3 million, in collaboration with GE Vernova, improved casting yield from 40% to 90% and reduced energy use by up to 90%. - DDM said its technology was originally developed at Georgia Tech beginning in 2007 with $6.3 million in foundational research funding. - The company partners with Oak Ridge National Laboratory on DOE-funded high-performance computing modeling of the LAMP process. - DDM says it holds 26+ patents across six countries and is ITAR-registered. - The company says the United States has lost 67% of its foundries since 2000. - DDM cites Boston Consulting Group analysis that aerospace executives have called castings and forgings their number one supply chain problem for two consecutive years. - The company says 73% of B2B buyers now use AI tools in procurement research, and AI-referred sessions convert at roughly five times the rate of traditional Google organic search. - DDM says more than 25% of new facilities above 500 MW will have behind-the-meter power by 2030, up from 1% today, citing GE Vernova projections. - The company defines behind-the-meter power as dedicated on-site gas turbine generation for a single data center facility, bypassing the utility grid.

Between the lines: - DDM Systems is framing its technology as a supply-chain workaround for a physical manufacturing limit, not just a software or logistics problem. - The pitch also suggests AI infrastructure spending is creating spillover demand in heavy industry, especially for foundries and superalloy casting. - The repeated emphasis on federal funding and OEM partnerships is meant to signal that the process has moved beyond lab-scale research.

What's next: - DDM Systems is likely to keep targeting turbine OEMs, hyperscalers, and energy developers that need faster access to cast hot-section parts. - If turbine demand keeps rising, the company is betting its tooling-free workflow can win business from conventional foundries that cannot expand quickly enough. - DDM says its Digital Foundry can compress the casting timeline from months to days while maintaining the metallurgical quality turbine OEMs require.

The bottom line: - DDM Systems is pitching ceramic 3D printing as a practical answer to one of the biggest constraints on AI-era power generation: getting precision turbine castings made fast enough.
