LincSolution 3D Prints Heat Pump Parts to Target AI Data Center Cooling

Korean manufacturer LincSolution is developing metal 3D printed heat exchanger components for heat pumps, with AI data center cooling as a key target market. The company is part of a consortium researching how additive manufacturing can produce the micro-channels and composite structures that next-generation heat pumps require, and it is building a dedicated mass-production facility in Daejeon scheduled to open in 2027.

Why 3D printing fits the problem

Conventional heat pump manufacturing relies on cutting, bending, and joining separate metal parts. That approach works for simple channels but struggles with the complex internal geometries that modern refrigerants demand. LincSolution says metal 3D printing can produce micro-channels and composite structures as single, unified parts: geometries that are difficult or impossible to achieve using conventional methods.

The design freedom matters because the industry is shifting to a specific refrigerant. R290, a propane-based natural refrigerant, has minimal global warming potential, but it is highly flammable. That means heat pump designers need to extract maximum heat-exchange performance while using as little refrigerant as possible. Complex internal channel geometry is one of the best ways to do that, and 3D printing is one of the best ways to produce that geometry.

The Daejeon AM Foundry

LincSolution plans to use the consortium's research to standardize manufacturing processes for its core heat pump components and validate long-term reliability, building toward commercial production. The results are slated to feed into the company's AM Foundry, an additive manufacturing mass-production platform under construction in Daejeon targeting full operation in 2027.

From Daejeon, the company plans to move into higher-value markets: AI data center cooling, electric vehicle thermal management, HVAC systems, and broader energy infrastructure. The AM Foundry is the infrastructure piece that makes that expansion possible.

The AI cooling connection

Data center cooling is becoming one of the most talked-about thermal management challenges in technology. AI workloads generate more heat than conventional computing, and the industry is running into the limits of air cooling in most existing facilities. Heat pumps and liquid cooling loops are the leading alternatives, and both depend on efficient heat exchangers.

LincSolution CEO Choi Geun-sik put it directly: the importance of high-performance thermal management is growing due to the energy transition and the growth of the AI industry. The joint research, he said, would help the company advance mass production for high-efficiency additive manufactured components and accelerate its push into data center cooling and mobility thermal management.

Similar projects elsewhere

LincSolution is not the only group exploring this intersection. Researchers in New Zealand reimagined heat exchanger design using additive manufacturing, building gyroid-structured stainless steel units that could not be produced conventionally. More recently, the Danish Technological Institute and Heatflow's AM2PC project built a 3D printed passive cooling component for data centers designed to reduce material use compared with conventional multi-part assemblies.

The common thread is part consolidation. A single 3D printed component replaces assemblies of multiple machined and welded parts, which reduces material use, simplifies recycling, and can improve thermal performance. For LincSolution's R290 heat pumps, that logic is especially strong: fewer joints mean fewer potential leak points in a system handling flammable refrigerant.

What it means for additive manufacturing

Thermal management is emerging as one of additive manufacturing's clearest paths to industrial relevance, and AI infrastructure is the market pulling hardest in that direction. LincSolution's Daejeon facility, if it delivers on its 2027 timeline, will be a tangible example of how AM is moving from prototyping to serial production for a real industrial application.

The company's approach also illustrates a pattern that runs through much of the AM industry: design freedom, not just production speed, is the real value driver. Heat exchangers are not about making one part faster. They are about making a part that could not be made any other way. That is the argument that wins industrial customers, and LincSolution is building a business around it.
