Who Wants a 3D Scanner, Anyway? 60

splineboy asks: "In June 2002 a sun-starved computer engineer walked into a small room armed with an old PC, a 20 year-old video camera, some lasers, glass rods and an awful lot of duct tape. His mission was to create a program capable of converting a real world object into a computer model that could be manipulated, stored and eventually reproduced using stereolithography. After several hours of gluing, taping and generally walloping things with a hammer, Project Splinescan was born. Originally running on a batterd old machine (AMD-500), the prototype scanner proved the concept of low cost 3D scanning with a few rough scans. Now that a stable, multi-platform 3D scanning solution is on the horizon (even high school kids are building their own) - a question rings clear through the ether: 'OK, you proved you can make it work, but what's it good for?'"
"What are the potential uses of a portable, low cost 3D scanner? Medical? Animation? Special Effects? Archeology? Ceramics? Lego Modelling? I've got my ideas about why 3D scanning seems to be getting so popular, but how would you like to see these projects developed in the future?"

    Unfortunately, soon after his triumph, his most brilliant computer game designs were stolen by one of his company's executives, who passed them off as his own. After breaking into the corporate building and hacking into the computer network to attempt to locate evidence of the theft, he mysteriously vanished, and was not heard from for some time. Eventually, he resurfaced, spouting wild tales about 'talking to programs' and 'surviving the game grid', but bearing concrete evidence of the executive's misdeeds. The prevailing explanation for his bizzare behavior is chronic drug abuse. Whatever the reason, he persists in such delusional beliefs to this day.

        Well, it's not like you're looking to replace the bone - most prosthetics / joint replacements etc. are artificial. For the doctors, the hard part is sizing, where 3d scanning probably won't be too helpful until we can generate internal scans. For the engineers who develop the actual parts though, 3D scanning is fairly common to use as a modeling tool not just for the development of the prosthetics but also in the development of surgical techniques and tools to repair the bone or actually implant the thin
    • At home?

      If you're in a hospital capable of the implant, you're probably going to have better methods of 3D scanning and reproduction. That said, you'd have to take the original bone out, scan it, and then put in the replacement, assuming the bone isn't broken as to be unscannable. If you're just talking about a "standardized" bone, a more suitable bone could be created by a doctor/engineer in CAD.

      • No need to take the bone out, that's what we have CAT (computerized axial tomography) and MRI (nuclear magnetic resonance imaging) for: to take pictures of our insides without having to cut us open. Seriously, there are places that already do this and a few patents on the topic of automatically or robotically creating or custom milling a prosthesis specifically for one person's hip socket or replacing part of a pelvis or part of the zygoma after tragic accidents.

    As someone who works (more or less) within the hearing aid industry, I can tell you right now that 3D scanners are the Next Big Thing (tm) in custom medical products.

    The ability to take a mold for any sort of custom prostethic - be it an ear mold, arch support, or whatever - and then transmit that mold electronically rather than having to physically mail it is tremendous. I mean, shipping companies won't appreciate losing all that business, but any healthcare professional that has to deal with mailing dozens of custom molds a week will be overjoyed at the ability to send those scans around for free at any time of the day, and be able to trim another 2-3 days off the custom prothesis creation timeline.

    I mean, aside from the obvious speed gains that could be had for 3D modeling for movies and games.

    I worked at a company where 3D imaging of plaster models of teeth was a critical component to the business model. Scan teeth into computer, rearrange teeth, produce output for devices that move teeth into new positions like braces.

    Any game where you need lots of real-world content (eg. The Sims) would benefit from being able to create lots of varied stuff quickly and cheaply.

    3d scanning and printing will make Miniatures Wargaming a much more active hobby. Imagine, instead of waiting for Games Workshop to sell you some incredibly overpriced Space Marine, you can just copy your buddy's. Have a cool "kitbash" (homemade modification)? Publish it and let others download it. This is why I see the current business model for Games Workshop and all the other minitures companies radically changing by 2015. It will become a much more fan-centric hobby.

  • The guitar is popular with mucians even though there are more advanced technologies available.

    A different input helps the creatuve process.

    This isn't to say 3d Raytracing is obselete obviously. But this allows a differtn way of doing things.
    • What guitar replacing advanced technologies do you speak of? The only thing I can think of is the electric guitar (no more expensive resonance construction, let the amp do it!) and that seems to have enjoyed extreme success.
      • I mean, if you compare the potential of the music software and keyboard combo to the guitar (electric or whatever), we wonder why the guitar is more popular.

        Yes, there's the popularity of it but the point I'm making is that sometimes it's not the best technology that inspires most.

        Possibly not the best analogy. Just trying to say that by changing the input technology you change your way of seeing things.

  • Manufacturing is getting pretty automated, however there's still plenty of room for more automation, such as the design.

    Say you want to manufacture a plastic or metal non-mechanical part. If you could scan it very accurately, and then have that object's dimensions and characteristics imported into a CAD program, you can then use the CAM side (Computer Aided Manufacturing) to generate code that can run in a machine.

    The implementation of this is most important, and of course your scanner would have to be e

Keep up the good work! But please don't ask me to help.
