As biologists are busy working on cloning living organisms, engineers are working on a mechanical counterpart – creating non-living things that can replicate themselves. Recently, more than 100 researchers from around the world have been working on a project called RepRap (Replicating Rapid-prototyper), which started in 2004. At the Cheltenham Science Festival in the UK, the [...] I love the concept of 3D printing. Of course, I also really enjoy teaching Calc II when we talk about slicing and shell formulas and volumes of revolution, because I remember the AHA! moment when I suddenly put together what the formulas were all describing and it all made perfect sense. (Sadly, this [...] 3D Printing is a type of rapid prototyping. Material is layered and connected to form a 3 dimensional object. By using 3D printing, prototypes can be developed faster, and in full color. This is the only type of rapid prototyping that allows for full color prototypes to be produced. 3D Printing is also a leading [...] 3D Bioprinting new blood vessels or even organs may be possible in the future. A first step has been taken with the first commercial bioprinter, by Organovo. It currently prints cell structures but nobody has dared to put them in their bodies yet. So while this looks like a promising development, I’d take good care [...] 1. Machine Cost — Be sure to find out what you get in the basic price and what 2. Initial Consumables Kit — Some companies rely on consumables as a major 3. On-going Consumables — [...] |
