Hybrid 3D printing has had a heavy focus in the research of electronic and electromagnetic devices. The new degrees of freedom offered by hybrid 3D printing are enabling new device concepts that were not feasible previously. These include 3D volumetric circuits, conformal frequency selective surfaces (FSSs), volumetric and conformal antennas, 3D printed transmission lines, and more. Flexible hybrid electronics (FHEs) are of a particular interest due to their wide range of applications, including flexible displays for augmented reality and virtual reality, flexible electronic textiles, soft robotics, biomedical sensors, communication arrays, antennas, and FSSs. Hybrid 3D printing enables devices to have complicated inhomogeneous structures that FHEs benefit from. However, while the hardware capabilities of hybrid 3D printers are mature enough to manufacture such devices, the software capabilities remain primitive and are currently the limiting factor. In the area of conformal printing, three-axis systems are limited to printing on shallow slopes. Printing onto steeply sloped surfaces is not possible with three-axis machines because the tools will crash into the part. This issue is normally addressed by using a five- or six- axis printing system, which are typically more expensive, slower, have poorer accuracy and are more difficult to maintain. Another area of concern is printing embedded conductors within a dielectric package. This is prevalent in FHEs today, where embedded circuitry is important to avoid unwanted exposure of the conductive traces. Current techniques to achieve this include backfilling cavities with conductive material or printing multiple parts at once and assembling them together post-process. This talk will cover our research of a software solution to print 3D volumetric structures and print conformally onto steep surfaces using an ordinary three-axis machine. This will give people the ability to manufacture complex FHEs with electromechanical functionality faster and at a fraction of the cost. Multiple printed functional devices are demonstrated, including a hybrid printed flexible substrate with conductive connections, a conformal FSS, iterations of a 3D volumetric circuit, and volumetrically complex antennas that operate close to fundamental limits. The presentation will also feature how the software can be applied to FHEs in real world settings.
