2015 continues to promise new 3D printing innovations. Stereolithography, using a UV laser to harden materials layer by layer, originated in the early 80's, and at that time 3D printers sold for around $100,000. As the technology evolves, prices have come down, and now consumer versions of these printers can be purchased for under $500.00. These 3 dimensional robots can even build themselves. 

   Printing technology has grown from a small faction into a large community over the last 20 years and now includes an open-source community named RepRap. Modern printers utilize fusion deposition, which uses melted extruded plastics such as PLA, Nylon, and the more common ABS, to form 3D objects layer by layer. These layers are typically about 4 mils, which is as thin as a sheet of paper. 

   At CES this year, Makerbot announced their plans to release new filament (the printable material) at the end of 2015 which mimics the look and feel of limestone, maple wood, iron, or bronze. Michael Toutonghi, formerly of Microsoft and Parallels, announced his plans to release a new filament that allows anyone to print circuits, wires, sensors, power connectors and other electrical components inside 3D-printed products.  Marketing Technologies has published a professional low cost 3D printer comparison.

The days of fusing electrical and mechanical design are just around the corner!  - NS
