“…This allows for the manufacturing of extraordinary 3D heat sinks for cooling electronics with enhanced conjugate heat transfer and fluid dynamics that are otherwise impossible to manufacture with conventional manufacturing methods. Most research in this area has dealt with air-cooled heat sinks, typically natural convection or forced convection, taking advantage of creating novel intricate fin shapes with rougher surfaces [97]. While current heat sink designs rely on human perception, simulation, testing and rethinking with the constraints of conventional subtractive manufacturing, computational optimization for tomorrows designs are gaining increased attention with the advances in AM processes.…”

View full text Add to dashboard Cite

This roadmap aims to define the guidelines to maximise the impact of the 3D printing revolution on the next generation of devices for the energy transition. It also outlines the current status, challenges and required advances in Science and Technology for a series of power generation technologies (fuel cells, solar cells, thermoelectric generators and turbomachinery) and energy storage technologies (electrolysers, batteries and supercapacitors). Finally, the roadmap discusses the role of 3D printing in improving the mass and heat transfer to improve the energy efficiency of chemical reactors (CO2 conversion) and novel cooling systems. With this document, the authors intend to provide a valuable tool for researchers, technology developers, and policymakers when defining their strategies for the energy sector's future.

“…This has been further confirmed in the study of Mertova et al, 2020 [ 3 ] where surface area was identified as a decisive factor contributing to mechanical performance degradation. Lattice structures are characterized by a large surface-to-volume ratio that improves their thermal dissipation efficiency [ 32 ] but could result in material defects due to the surface’s lack of fusion [ 6 ]. There are also possible internal defects such as the lack of fusion, keyhole collapse, or gas porosity due to limited track of the laser beam during the melting process on small cross-sections.…”

Additive Manufacturing of Honeycomb Lattice Structure—From Theoretical Models to Polymer and Metal Products

et al. 2022

View full text Add to dashboard Cite

The study aims to compare mechanical properties of polymer and metal honeycomb lattice structures between a computational model and an experiment. Specimens with regular honeycomb lattice structures made of Stratasys Vero PureWhite polymer were produced using PolyJet technology while identical specimens from stainless steel 316L and titanium alloy Ti6Al4V were produced by laser powder bed fusion. These structures were tested in tension at quasi-static rates of strain, and their effective Young’s modulus was determined. Analytical models and finite element models were used to predict effective Young’s modulus of the honeycomb structure from the properties of bulk materials. It was shown, that the stiffness of metal honeycomb lattice structure produced by laser powder bed fusion could be predicted with high accuracy by the finite element model. Analytical models slightly overestimate global stiffness but may be used as the first approximation. However, in the case of polymer material, both analytical and FEM modeling significantly overestimate material stiffness. The results indicate that computer modeling could be used with high accuracy to predict the mechanical properties of lattice structures produced from metal powder by laser melting.

“…As previously mentioned, corrosion resistance and low electrical conductivity is also highly relevant. Additive manufacturing methods have recently been able to produce a variety of complex structures suitable for cooling [3,4]. Simulation-based design optimisation, such as the topology optimisation method [6], often generates complex organic shapes that are highly performant.…”

“…Additive manufacturing as a manufacturing method has many additional design freedoms compared to traditional methods, allowing for more complex structures of heat sinks. For this reason, additive manufacturing is often used to produce complex structures that are optimised for efficient cooling [3,4]. However, there are also challenges in using additive manufacturing methods.…”
