3d printing feels like dumbed-down CAD/CAM.

QuoteOriginally posted by: Cuchulainn3d printing feels like dumbed-down CAD/CAM.How do we know we not live inside a massive 3D printer? we just wait and see what happen when it run out of ink? and what about seeds or plant clones, they are good 3D printers, precise instructions are used to "print" new 3D structures, but yes they must be supplied with ink to print, earth, water, air and fire. Clones ( I made thousands of plant clones before) is more like 3D copy machines, seeds are more like 3D creativity...but yes I guess we want to extend this to cars, flat screen TVs etc....think when we can buy car seeds, car seeds must be planted on earth high in iron, and they would also use CO2 to grow...was this the garden of Eden, where people could plant seeds for anything they wanted? 3D printers are everywhere, just need to understand how they work, and push the right bottom to make they print what you want! Good to have land!!

QuoteOriginally posted by: Cuchulainn3d printing feels like dumbed-down CAD/CAM.The CAD part doesn't change, but many of the constraints on the CAM side disappear.Would a computer language with fewer syntax constraints be a dumbed-down language?And, in actuality, the advanced 3-D printers call for much more sophisticated CAD/CAM on the design simulation/analysis side because the printer can simultaneously combine multiple materials in one print job. Analyzing deflections and stresses in heterogeneous materials requires an order of magnitude more smarts than that required for homogeneous materials.

For constructing it in time? (it's 3D in Minkowski space-time)If construction time is proportional to the amount of material, then this object can be constructed in O(N^2) time where N is the length of one side.And if we can make a Sierpinksy tetrahedron by explosive erosion of the empty parts, then we might be able to do it in O(Log(N)) time!

Does that mean that we get an infinite amount of Sierpinksy tetrahedron from a solid one?Indeed we do! All those holes in the Sierpinksy tetrahedron are filled with more Sierpinksy tetrahedra.****And now we've swung over to pendulum time
