These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to show how the cost and performance of additive manufacturing/3D printing is experiencing rapid improvements and thus it is becoming economically feasible for many new applications. All 3D printers have benefited from improvement sin microprocessors and sensors, which have enabled better process control. One new and one existing technique and the impact of improvements in electronic components on the performance and cost of additive manufacturing are discussed. First, continuous liquid interface production is a new technique that utilizes a unique design of digital light processing, a deadzone, and an oxygen permeable window. Improvements in the resolution of DLP, a form of MEMS, are occurring as smaller feature sizes are achieved, in the same way that increases in the number of transistors are achieved as transistor gate lengths are reduced. Second, an existing approach, Selective laser sintering, experiences improvements as higher powered lasers emerge. This technique melts metal powder and wires with an Ytterbium fiber laser whose power capabilities continue to be improved. This technique has already enabled GE to reduce the number of parts for an engine nozzle from 18 to 1, the weight by 25%, and the costs by a similar amount. The number of applications for SLA is expected to grow as the technique is improved through the use of higher powered lasers.
