Abstract Scope A current effort is described that is focused on building small heat exchangers suitable for use with supercritical CO2. Conventional design is based on diffusion bonding whereas 3D printing allows considerably more freedom of design. The constraints and advantages of additive forming in a laser based powder bed machine are described, as they influence the changes in design that have been implemented. Residual stress is significant, for example. The current limits of resolution are described in terms of the smallest feature that can be built such as thin columns or tubes. Microstructures and basic properties resulting from mostly successful efforts to build prototypes in various materials are described. Overall it is already clear that additive printing of small heat exchangers is a viable forming route.
