AmPd Labs and Continuum test binder-jetted MAR-M 247LC against investment casting

AmPd Labs is stress-testing binder jetting on MAR-M 247LC, a nickel-based superalloy long associated with investment-cast aerospace propulsion and energy hardware. Working with Continuum Powders, the company will present mechanical testing that compares binder-jetted MAR-M 247LC with conventionally cast material, plus the materials science and qualification steps behind those results. AmPd Labs CEO Tim Neal and co-founder and COO Sean Harkins will speak for the process side, while Continuum vice president of research and development Dr. Sunil Badwe covers powder and metallurgy. The companies will detail the work in The Future of High-Temperature Superalloys, a free webinar on August 6, 2026 at 2:00 p.m. ET.

Binder jetting already competes for serial metal production where throughput and tool-free geometry matter; high-temperature nickel superalloys remain a steeper materials bar. MAR-M 247LC parts still default to investment casting, with tooling, long lead times, and supply-chain friction that aerospace, defense, and energy programs absorb as program risk. Matching cast baselines is the correct commercial threshold for AmPd Labs: hot-section buyers will not swap process routes on machine claims alone. Continuum's powder and process-window role is equally central, because densification, chemistry control, and property scatter in sinter-based routes often dominate outcomes more than the print step itself.

For buyers and program engineers, the open question is whether binder-jetted MAR-M 247LC can clear the mechanical and repeatability thresholds already owned by qualified cast routes. Treat this as a materials-and-qualification campaign, not a printer story: sintering control, residual porosity, and property parity will decide if AmPd Labs can open low-volume or serial production slots. Until property data and qualification artifacts land in customer specifications, cast routes remain the default for flight-critical and hot-gas-path components.
