What Sintavia does
Sintavia, LLC is a privately held, vertically integrated designer and additive manufacturer of Power & Thermal Management System (PTMS) components for the Aerospace, Defense, and Space industry, headquartered in Hollywood, Florida. The company operates an 87,000 square foot production facility housing 23 large and extra-large industrial metal printers (EOS M400-4, AMCM M4K-4, SLM NXG XII 600 twelve-laser machines, GE Additive Arcam electron-beam units), co-located with hot isostatic pressing, vacuum heat treatment, wire EDM, machining, surface finishing, an ISO 17025/ANAB-accredited metallurgical and powder laboratory, industrial CT scanning, and full mechanical testing. Sintavia has developed over 50 proprietary metal parameter sets across nickel, copper, titanium, aluminum, and refractory alloys — including proprietary niobium and GRCop-42 copper printing recipes — that underpin its ability to qualify components against Nadcap, AS9100, and ITAR-controlled aerospace requirements.
The company's product portfolio is organized into three families: Thermodynamic Systems (tube-fin and shell-tube heat exchangers, thermal transfer chassis), Propulsion Systems (thrust chamber assemblies, attitude thrusters, hypersonic propulsion components), and Power Systems (shrouded impellers, turbomachinery, battery housings). It also sells Design (DFAM), Lab Services, and Quality Conformance as integrated service offerings, with NDT capabilities operated through the wholly-owned subsidiary QC Laboratories, Inc. Revenue is generated through direct enterprise contracts with Aerospace & Defense OEMs and defense primes — including Lockheed Martin, Boeing, Northrop Grumman, GE Aviation, Rolls-Royce, Blue Origin, Curtiss-Wright, and Embraer — for the development, qualification, and serial production of PTMS components and subsystems. Reported outcomes include up to 40% weight reduction, 10x faster product delivery, and 90% lower development cost versus conventional manufacturing for power-system components.
Sintavia was founded in 2015 by Brian Neff and is funded through strategic investments from Sumitomo Corporation of Americas (2018, 2020), Lockheed Martin (2023, as part of the White House AM Forward initiative), and a $10 million subordinated debt facility from the Stifel North Atlantic AM-Forward Fund in February 2025. The company is positioned as the leading independent metal additive manufacturer in U.S. aerospace and defense, with a stated focus on NVIDIA GPU-accelerated design workflows, hypersonic and naval propulsion programs, and ongoing $25 million facility expansion in Hollywood, Florida.

Product offeringCore offering
Sintavia designs and additively manufactures complex Power & Thermal Management System (PTMS) components and subsystems for the Aerospace, Defense, and Space industry. It produces three core product families—Thermodynamic Systems (heat exchangers, thermal transfer chassis), Propulsion Systems (thrust chamber assemblies, attitude thrusters, hypersonic propulsion), and Power Systems (shrouded impellers, battery housings, turbomachinery)—using proprietary metal parameter sets for aerospace-grade alloys on a fleet of 23 large-format industrial printers, supported by in-house design, post-processing, metallurgical laboratory, and non-destructive testing capabilities.
Product overview
Sintavia is an aerospace component manufacturer offering a vertically integrated platform for the design and additive manufacturing of Power & Thermal Management Systems (PTMS). The company operates a unified portfolio organized around three core product families—Thermodynamic Systems (tube-fin and shell-tube heat exchangers), Propulsion Systems (thrust chambers, attitude thrusters, hypersonic propulsion), and Power Systems (shrouded impellers, turbomachinery, battery housings)—supported by in-house Design, Manufacturing, Lab Services, and Quality Conformance capabilities. All offerings leverage proprietary metal parameters for Nickel, Copper, Titanium, Aluminum, and refractory metals, with full in-house capability from powder analysis through post-processing and non-destructive testing. The portfolio is delivered as a single integrated service rather than modular components.
