The ability to transmit heat over long distances with a small temperature gradient is a highly coveted feature in thermal management and cooling applications for electronics. Heat pipes play an important role in these applications since they consist of wick structures, which provide the necessary capillary action to transport the working fluid from the heat source to the heat sink. Heat pipes also do not require external systems such as pumps, fans, external power, or other moving parts since they rely on capillary action, and are hence considered reliable. Wick structures typically consist of grooves, screen/mesh, or sintered metal powder. Each type of wick structure has a distinct advantage that makes it suitable for certain applications. For the purposes of this work, sintered metallic wick structures are considered for their high capillary action. Existing manufacturing capabilities pose significant barriers to the creation of wick structures for efficient heat transfer – they are time consuming and do not offer the ability to control porosity. This work examines the feasibility of a novel manufacturing technique for developing microscale metallic porous structures using a pulsed microsecond carbon dioxide (CO₂) laser. The preliminary results show the successful fabrication of a sintered copper powder structure at a pulse period of 1000 µs, a pulse width of 180 µs, over 30,000 intermittent pulses. To obtain validation of the sintering quality, laser sintered samples are compared with conventionally sintered samples based on similar parameters. Computational models of the laser sintering process to manufacture metallic wick structures are developed using FLOW 3D™ to obtain an understanding of the underlying phenomena.  The main benefit of this new manufacturing process is that it provides a significant reduction in manufacturing time. The obtained results provide a crucial step toward developing a new class of manufacturing process for metallic porous structures.
