Mydesign, 4D printing is defined as 3D printing plus another dimension--time, which is commonly known as the fourth dimension. By "time" this usually means 3D printing an object that, because of characteristics of its material, then changes its shape over time. Personally, I think the designation is silly, which is why I didn't use it when reporting on Skylar Tibbits' work here: http://www.designnews.com/author.asp?section_id=1392&doc_id=260118 At the time of my report, his TED talk wasn't available, but you might want to check it out--we give a link in today's blog. The technology I'm reporting on here is using "4D printing" techniques to create self-assembling objects.
"Researchers at the University of Colorado Boulder have combined 3D printing on the Objet Connex multi-material 3D printer with making shape-memory composites, calling that process 4D printing."
Ann, I won't think that's a 4D printing and it may need some clarity about 4D and 5D printing technology. Printing a 3D image of 3D object won't be defined as 4D printing. I heard that adding another dimension to 3D printing can lead to a 4D printing.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
Independent science safety company Underwriters Laboratories is providing new guidance for manufacturers about how to follow the latest IEC standards for implementing safety features in programmable logic controllers.
Automakers are adding greater digital capabilities to their design and engineering activities to promote collaboration among staff and suppliers, input consumer feedback, shorten product development cycles, and meet evolving end-use needs.
