I guess, technically PVA is available commercially. From what Iv'e seen of it in use though, it isn't very practical. The material itself is quite finnicky and extremely expensive compared to PLA and ABS. At the price of that stuff with the issues I've heard of, you might as well just have it printed in higher quality through a service.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
