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.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
