"Digital" materials is the new "i" anything, strictly a marketing term. These materials are manipulated by an electro-mechanical device controlled digitally and the shape that it making arose from a digital file.
Semantic argument aside the technology is fascinating and the proliferation of materials that are compatible with these 3-D printing processes can only serve to make the life of the design engineer simpler. Printing a 3-D part is a first step in the evaluation of a design, does it look, fit, etc. as I expected. If so, good, I can make a more functional prototype with more appropriate materials, if not, good, I didn't spend too much money or waste too much time.
I look forward to the growth of this technology, but I won't be calling these 3-D inks "digital materials".
That's my impression, too, Rob. Objet has been quite consistent in its drive to make more materials available for its 3D process, to serve the need for function as well as for form and fit, in prototypes and models.
Hi - some clarity on our Digital Materials: Digital materials are composite materials made of 2 physical cartridge base materials. The two Objet model materials are integrated in specific concentrations and structures to provide the desired mechanical and thermal properties; enables close simulation of the target product materials. Digital Materials are generated on the fly during the printing process using a software algorithm which defines the jetting pattern which results in the composed materials structure. Digital materials do not exist as cartridge-based materials but only in the resulting model or part.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
