TEMISTh, a leader in heat exchanger manufacturing, partners with Eplus3D to advance metal AM for thermal solutions. With Eplus3D Metal AM Solutions, TEMISTh produces complex nickel-alloy heat exchangers with 99.9% density for extreme conditions. A key application is the DESOLINATION project, where 3D-printed heat exchangers enable efficient solar-powered desalination. The technology halves production time, enables modular large-scale assembly, and overcomes traditional manufacturing limits. This collaboration demonstrates AM's transformative potential in aerospace, energy, and sustainable technologies, showcasing Eplus3D's industrial AM leadership and TEMISTh's innovation in high-performance thermal management.
Ludwigsburg, Germany - March 2025 - TEMISTh, a pioneer in customized heat exchanger design and manufacturing, is leveraging Eplus3D’s advanced metal additive manufacturing (AM) technology to redefine thermal solutions for aerospace, defense, and energy industries. Since 2012, the Southern France-based company has specialized in extreme-condition applications - from cryogenic systems (cryogenic to 1000K) to high-pressure environments (up to 1000 bars) - and now integrates Eplus3D’s Metal Powder Bed Fusion (MPBF™) technology to overcome the limitations of traditional manufacturing.
Breaking Barriers in Heat Exchanger Production with EP-M300
TEMISTh’s adoption of the EP-M300, equipped with a 300x300x450 mm build volume and dual 500W lasers, enables the precise fabrication of complex, lightweight heat exchangers with optimized internal flow channels. By combining CFD-driven fluid dynamics and FEA-validated mechanical designs, TEMISTh can now produce high-performance nickel-based alloy components, such as cold plates, that withstand extreme conditions while reducing material waste by up to 40% and cutting production time in half compared to conventional methods.

Real-World Impact: The DESOLINATION Project
A key application of this collaboration is TEMISTh’s role in the groundbreaking DESOLINATION initiative, which integrates Concentrated Solar Power (CSP) with advanced thermal exchange technology to revolutionize water desalination. The core challenge lies in optimizing heat transfer between supercritical CO2 and a highly concentrated desalination solution - a task requiring intricate geometries that only AM can achieve.
Using the EP-M300, TEMISTh successfully 3D printed IN718 nickel-alloy heat exchanger cores with a 50μm layer thickness, completing the build in 130 hours of continuous printing. Post-process heat treatment achieved material density exceeding 99.9%, while the modular design allowed welding assembly into large-scale heat exchangers (0.4 x 1.2 x 1.6m³) - surpassing traditional manufacturing size constraints.

Rigorous testing under DESOLINATION conditions - high temperature, extreme pressure, and corrosive exposure - confirmed structural integrity and performance alignment with operational demands. These results not only validated CFD/FEA simulations but also established critical mass production parameters, proving the feasibility of AM for industrial-scale thermal solutions.
Why EP-M300 Stands Out in Industrial AM
The EP-M300’s dual-laser system accelerates production speeds without compromising precision, making it ideal for high-throughput industrial applications. Its large 300 x 300 x 450 mm build volume breaks traditional size barriers, enabling modular assembly of oversized components like multi-part heat exchangers. With material density exceeding 99.9% post-treatment, the printer delivers exceptional part integrity for extreme environments, from aerospace to energy systems. Furthermore, the system’s seamless compatibility with post-processing - including heat treatment and welding - ensures smooth integration into existing manufacturing workflows.
Leadership Perspectives
Jean-Michel HUGO - CEO TEMISTh, commented:
