3D printing & self assembly natural partners

Thanks for sharing this.  I watched the underwater cube, then I watched Skylar's TED talk as well.  When you think about a system like this, it makes sense that 3D printing (or some form of 3D manufacturing) and self-assembly go together--things we want in the world are mainly 3D, so they are assembled out of 3D parts (the printer that prints out of stacked sheets notwithstanding--they are still 3D--they have thickness!).

It is interesting to think about gravity as the main source of energy (potential energy) and building structures.  In a sense, this is already done on a large scale or certain types of retaining walls.  You have 3D blocks that fit together, and gravity provides the force to keep them together.  I have seen some blocks for walls that are very large--think a concrete lego brick the size of a bale of hay.  Some I have seen have bumps on one side and dents on the other, so they stack and won't move horizontally, and gravity does the rest.

On a smaller scale, I wonder what could be done with structures that respond to other sources, such as thermal, and pH, or even blood chemistry, and how those could be used in the body.

eafpres, thanks for the feedback. My April feature on self-assembly and self-reconfiguring robots will touch on several of these subjects. If you're interested in nanoscale self-assembly, I suggest you check out DNA origami and the Wyss Institute work on DNA 2D tiles and 3D bricks.

@Ann: Do you intend to have anything to do with AI in the future ? I would love to join  if so since I think AI can add some value towards this.

a.saji, AI is a fun topic for discussion in the comments, but it's not a regular topic for coverage in Design News, at least for now.

@Ann: Yes Ann I do get your poiunt. What I really wanted was to involve AI into the project so it will have loads of benifits.

a.saji, sorry but I don't understand what you're getting at. Involve AI in what project? One you are working on? Please tell us more.

@Ann: Yes Ann I'm working on a AI project which involves some other electronic methodologies too. It can be used to detect the facial expressions which might or I'm trying to make it suited for ATM or even Healthcare and IT systems. I feel by doing this, the risk will get mitigated to a certain level.

@Ann: Have you tried 3D Printing by any chance ? What is your idea on it ? Do you think it can have bad impacts to the world we live ?

a.saji, I have not personally used 3D printing. I've talked to people who have used it, mostly the high-end machines producing engineering prototypes and small-batch end-products for aerospace. Like any technology, it could have negative impacts on our world, which we've discussed in the comments sections to many stories in Design News.

@Ann: Yes there are always 2 sides of everything and same theory applies for this as well. I feel 3D printing is superb and will be the next big thing in IT but the fear is what if it goes in the wrong direction. What kind of negative impacts will it have ?

a.saji, can you say a bit more about what you think is "the wrong direction"?

@Ann: If people try to misuse the beauty of technology creations, then the outcome will be utterly dangerous. That is where you take the wrong turn on things.

HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
