Additive manufacturing processes are capable of printing parts with any shape and complexity. The parts fabricated with additive manufacturing processes requires minimum human intervention. Process planning decisions play an important role in making sure the fabricated parts meets the desired specification, including the build time and cost. A quick and unified approach to quantify the manufacturing build time, accuracy, and cost in real time is lacking. In the present research, a generic and near real-time framework for unified additive manufacturing process planning is presented. We have developed computational geometric solutions to estimate tight upper bound of manufacturing process planning decisions that can be analyzed in almost real time. Results of developed computational approach are compared against the optimized process plans to ensure its applicability. Case studies comprising of numerous parts with varying shape, and application area is also outlined.

Abstract This work outlines the development and testing of novel in-situ atmospheric sensors. The system is designed for deployment of the sensors en masse to increase the geospatial density of atmospheric measurements. This sensor system is being designed to replace the costly, larger atmospheric sensors currently in use. Improvement in sensor technologies, substrates, and additive manufacturing techniques have allowed for such a device to be realizable. The devices contain a sensor suite that gathers temperature, relative humidity, and pressure from microsensors as well as position, velocity, and heading from a compact GPS receiver. This data is then sent to a base station for analysis by atmospheric scientists, with the potential for real time analysis.
