Roger Garrett August 9, 2017 11:42 PM Pretty cool, but I'd want an additional criteria: Manufacturability. I'd want to tell it that it has to be, say, injection mold-able or cast-able or mill-able. As it is it appears that most of the designs it will come up with can only be made with some form of 3D printing, so not easily mass producible. KaiserPingo August 10, 2017 06:40 AM Great !Looks better and looks more "right". Get startet !!! UncleToad August 10, 2017 06:42 AM They look like something straight out of the Alien films! Let's hope there isn't a facehugger hiding inside!!Paul Bob Stuart August 10, 2017 09:44 AM Those hubs and struts need a lot more optimization, both for efficient placement and economy of material. Force wants to move in short, straight lines. Bones are beams with complex loading and hinge shapes, while struts are simply loaded. The program needs some initial direction in how to create an efficient pattern. GDubAZ August 10, 2017 01:27 PM If it's inspired by "evolution", shouldn't it just happen spontaneously on its own, with no input from a designer . . . ? f8lee August 10, 2017 01:38 PM @Roger Garrett - I think the point of the piece is that AM (additive manufacturing) IS becoming mass-production ready, though mass-custom-production ready may be the better term. ljaques August 10, 2017 03:52 PM I love the look of the engine block, lever, shoes, and lots of the architecture. Can't wait to see this happen on a local scale. To those wanting it to be injection-moldable, fergitit. Ain't happenin' due to the interference of removing the item from the mold. Perhaps some could be done by the lost-wax method, but that would require building the piece in the first place. As to optimization, I like it the way it is. Why ruin a good thing? Daishi August 11, 2017 01:20 AM So you place expected stress locations and figures and allow the algorithm to calculate the most efficient design. All good. My feedback is what about when the material is stressed from unanticipated angles? This part of the design still appears to rely on human input. To provide an example look at the chair. If you make the assumption you are simply placing raw weight on the seat of the chair the new design is much more efficient but with a seated human they shift their weight and lean back in the chair which the revised chairs would likely not be well positioned to support. Interesting stuff through. Robt August 11, 2017 09:23 AM @Daishi I don't think that would represent a problem, because the parameters that are used (even now) include a margin for the unexpected. It's really a question of what is 'dialled in' and as long as engineers are responsible for the initial input, that is likely to be on the conservative side - at least initially Dave222 August 12, 2017 12:30 AM Hmmm. Any thoughts on the seemingly increased exposed surface area subject to oxidisation, UV, dirt etc, which may increase deterioration, need for painting/coating, both of which might ADD to long term costs and weight? What about if floatation of component is needed, perhaps a simple sheet fabrication remains way more practical......to make, to float, to coat, to clean etc. Cool tech for the osteopathic surgeon, ie the broken jaw guy, not so smart for a pontoon boat float...roll a flat PE sheet into a cylinder, heat weld seam, jigsaw two discs for each end and also weld. Pphwwallla! Even though an organic shape like a dolphin seems like a cool idea how to optimise a boat, last I checked, Flipper doesnt come with cup holders, bimini, couches, cooler etc. Some things.............. Or......despite protein powders, nutri bars, pills and tubes of NASA like food, people are still falling over themselves to get a table at a rudely inefficient establishment called a restaurant! I suspect that some designers will be seduced by the cool factor of an engine block that looks like a Geiger creation, but in the long term I wish them luck earning the respect of mechanics that have to service them.
