Spes3D at Symkom 2023 conference

The ANSYS Software Users’ Meeting is an annual event for technology and computer simulation enthusiasts.

Krzysztof Kus (CFD Engineer at Spes3D) presented the conference participants with a case study of a new generation lattice heat exchanger, made by us using 3D printing in LPBF technology.

New generation heat exchangers


Our engineering team took on the challenge of creating a next-generation heat exchanger that is both more compact and more efficient than a standard plate heat exchanger.

This is in response to the needs of the automotive and aerospace industries, where these very parameters are crucial.


Instead of traditional exchanger plates, we used a Triply Periodic Minimal Surface (TPMS) structure.

This unique structure further turbulises the flow, resulting in intensified heat transfer.


  • Reduction in volume by 27% while increasing efficiency relative to a standard heat exchanger.
  • Material: 316L stainless steel
  • Technology: 3D printing using LPBF technology

Let’s create something new!

3D printing is our passion, and with the capabilities of one of the most modern machine parks in this part of Europe, we are able to create unique things just for you.

We are a team of experts in design, 3D printing and CNC machining. We will advise improvements. We will select the technology. We will prepare prototypes.
