"Generally, no this type of printing does not allow for a material that disolves. There have been a few experiments with it, but nothing in the commercial market yet."
There are some printers capable of processing PVA (polyvinyl alcohol) filaments. PVA is water-soluble and can thus be removed from the printed object. (A raised temperature, bath agitation and - maybe - a little addon-chemistry will help.)
Not only the guys from makerbot are offering a PVA filament to print removable support structures.
My first experience with 3D printing was at In Focus, the projector company many, many years ago. We sent out a projector case design to a stereo lithography (UV curing resin and a UV laser) shop. Someone, somewhere slipped a decimal point and the 20" part came back to us as a two inch part. It still makes me chuckle to think about it.
I think there's a hackerspace of some sort here in the Portland area that I need to check out.
@Caleb: I happen to know for a fact you have an awesome hackerspace right ther in huntsville! I've been there! It is the "Makers Local 256" and I do believe you may pass out from joy upon entering the building.
How come I'm always the last to hear about these things? LOL

The top 10 3d printers has been done over and over and over. Not to mention it changes every single day.
I think maybe the a more useful article would be "a crash course on what is important in a 3d printer's features" or something like that. Educate the buyer so they can decide for themselves. There's so much variety and marketing speak it is hard to find what you really need.
Generally, no this type of printing does not allow for a material that disolves. There have been a few experiments with it, but nothing in the commercial market yet. There are a couple printers out there that can print in 2 materials/colors right now though.
aside from colored plastic there is a wood material as well as some glow in the dark material!
If you want to print fully moving parts, you'll need to bump up to the 10k plus range and get a much fancier printer that doesn't lay down layers of hot plastic.
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.
