  • Cool technology

    Just another cool technology you guys and gals might be interested in. Although there would be issues with the current form, I thought it was just cool as hell. That this gizmo can "grow" a WORKING model is very impressive.

          I dunno. I just clicked on it and it worked fine. Sorry guys. I can't repair it if it ain't broke on this end.

            It is a link to a flash/shockwave video application. If you don't have the appropriate software/players installed it wont work.

              Stereolithography, aka 3D Printing. Been around for a while in various forms (the earliest used rolls of paper IIRC). The cost will come down to the hobbiest level eventually (and most likely be made in China). There are plans out on the internet for a do it yourself version http://fabathome.org/wiki/index.php?title=Main_Page cost estimate is arund $2000

                $2000? I bet I can build one for much less. I'll make it from beetle killed pine. I wonder if you can make one to work with concrete?

                  I worked with selective laser sintering, that was really cool. I understand the range of materials it can work has really expanded in the last few years and cycle-times/accuracy are improving.

                    Im taking a SolidWorks class at a local college right now and in the second half we get to model something within reason and use the 3-d printer to make it. They have a display of other stuff students have made and it is pretty impressive.

                    I was thinking of doing something like a mobius strip or a klein bottle, but the klein bottle wouldnt be see thru so I dont know. That and I dont think my math skills or drawing skills in solidworks is good enough yet


                    Someone posted a page a long time ago that had all kinds of cool models of mathmatical shapes, anyone got a link for that?

                      Can you put a cross-cap on a Klein-bottle or does that break the universe?

                      Wiki has some intresting stuff about Klein bottles, cross-caps and other interesting mathematical stuff.

                        reminds me of that time I tried to divide by zero...

                          Just being a smart-arse one day I casually mentioned the "square root of negative zero" in the presence of a mathematically inclined programmer, you could actually hear his brain go "pop."

                          We both had a good laugh about that.

                            It's the Jay Leno rapid prototype video - it's been presented before. Fun stuff out of my price range.

                              There's absolutely no problem with the concept of the square root of negative zero. IIRC, it should be negative zero according to IEEE-754. Yes, Dorothy, negative zero is something you have to deal with on computers.
