TEMISTh, a French firm specializing in warmth exchangers, has partnered with Chinese language metallic 3D printer producer Eplus3D to combine the EP-M300 metallic additive manufacturing system into its manufacturing course of. The adoption of the EP-M300 know-how permits TEMISTh to supply complicated parts extra effectively, decreasing materials waste and manufacturing instances in comparison with standard manufacturing strategies. One key software of this know-how is the DESOLINATION challenge, which integrates superior warmth exchangers into solar-powered desalination programs.
“Combining TEMISTh’s experience in warmth exchanger engineering with the precision and stability of our metallic 3D printer opens up new potentialities for superior thermal administration. This synergy will drive high-performance options that help economically viable decarbonization, redefining the way forward for energy-efficient industries,” stated Martin Bizot, Account Supervisor at Eplus3D Tech GmbH.
AM Capabilities of the EP-M300 System
The EP-M300 system, which contains a 300 x 300 x 450 mm construct quantity and twin 500W lasers, allows the manufacturing of light-weight parts with inner geometries optimized for warmth switch. These parts are designed utilizing computational fluid dynamics (CFD) and verified by way of finite component evaluation (FEA). The combination of AM has allowed TEMISTh to cut back materials waste by as much as 40% and reduce manufacturing instances in half in comparison with conventional strategies.
TEMISTh acknowledged that the EP-M300 was chosen for its dual-laser configuration, which improves construct pace whereas sustaining precision. The system’s massive construct quantity helps the manufacturing of modular, high-performance parts. It’s appropriate with commonplace post-processing strategies akin to warmth remedy and welding, permitting integration into present manufacturing workflows. With post-treatment materials density exceeding 99.9%, the EP-M300 additionally meets the half integrity necessities of industries akin to aerospace and vitality.
DESOLINATION Challenge Utility
The EP-M300’s capabilities are being utilized within the DESOLINATION challenge, which mixes Concentrated Photo voltaic Energy (CSP) with superior warmth alternate programs to reinforce desalination processes. The challenge entails managing warmth switch between supercritical CO₂ and a concentrated saline answer, which requires intricate inner geometries achievable solely by way of AM.
For this software, TEMISTh produced IN718 nickel-alloy warmth exchanger cores utilizing the EP-M300, attaining a 50μm layer thickness and finishing the method in 130 hours. After post-processing, the parts reached over 99.9% materials density. The modular elements had been subsequently welded into bigger programs (as much as 0.4 x 1.2 x 1.6 meters), which might be difficult to supply with conventional manufacturing strategies.
Efficiency assessments beneath the challenge’s working situations confirmed the structural integrity and alignment of the printed elements with the simulated design parameters, indicating the potential of AM for full-scale thermal purposes.
Eplus3D’s Latest Milestones
In January, Eplus3D marked a big achievement with the supply of over 100 “super-meter” metallic LPBF (Laser Powder Mattress Fusion) 3D printers globally. Practically 40 of those programs, together with the EP-M2050, EP-M1550, and EP-M1250 fashions, function X, Y, and Z axes all exceeding one meter in size. These numbers spotlight Eplus3D’s sturdy presence within the large-format, multi-laser metallic 3D printing market. The corporate attributes its success to the growing adoption of multi-laser know-how within the metallic additive manufacturing business.
At TCT Asia 2025, Eplus3D showcased the profitable 3D printing of pure copper and copper alloys utilizing red-laser know-how. This growth addresses the long-standing challenges posed by copper’s excessive reflectivity and thermal conductivity, which have historically hindered its processing in laser-based additive manufacturing. The newly developed course of permits for the manufacturing of secure, high-performance, meter-scale copper alloy elements with long-cycle reliability, with out the necessity for vital {hardware} modifications. This innovation is poised to learn industries akin to aerospace, automotive, and electronics, the place copper’s distinctive properties are extremely valued.
