    You're going to have to take it apart anyway to replace the bearings, so wait until you do that before ordering the new ones. A different length won't matter much, as Traykan says, but a different OD...

    Does this large CNC router really run entirely on unsupported shafts? That's not recommended over long spans. Do you have a way to press out the old bushings and press in new ones? If it were me...

    I've made holograms; they were always going to be the next big thing... Now people use the term for any 3D illusion, so nobody understands what they're really about. I didn't understand why they...
  4. Holographic 3D printing demonstrated - near instant results

    I always wondered if this would work, but researchers at Lawrence Livermore National Labs have demonstrated that it can. They illuminated a tank full of photo-catalyzed resin with 3 matching...

    For organic kinds of models - figures, animals, etc. - there's nothing better than the Geomagic line of haptic-enabled sculpting tools: Sculpt, Freeform, and Freeform Modeling Plus. It's a...

    The soluble filament is something that Stratasys developed and other companies are only starting to match. Airwolf is one company that's supposed to have a comparable solution (I haven't tried it...

    Is this something you're placing directly on someone's head and attaching hair to, or is it a mold or positive form for something you're casting in another material?

    As you mention, machines like this are commercially available, but costly. If I wanted to build one, I'd be tempted to start with an old Z-corp machine, which already has the mechanism for laying...

    Don't bother learning how to use the 123D apps; Autodesk discontinued them some time back, and since they were cloud-based, they no longer will work. I guess TinkerCAD is still functioning, though.

    Starting with a good scan would help a lot - you know the saying: "garbage in, garbage out". There are things you can do to improve results, like spraying models with flat white paint, if some areas...

    Did you get their help with writing this post? Did they come up with that "not more than a nightmare" phrase for you?

    A 3D printer would be a useful tool to have in your model shop, but probably not the only one you'll want. Knowing about modeling software will definitely help. Most downloadable models are in STL...

    Sorry, I haven't used those products. If you have, give Wrap a try and let us know how it compares.

    Take a look at Geomagic Wrap; it has a lot of tools for topology optimization. What exactly do you need to improve in your models?

    I don't think the support material those machines use is really PLA; it's a proprietary material that Stratasys developed which will dissolve in hot water that's got some chemicals added. They...

    You're not giving us much to go on here. There could be a problem with your model, but there also could be something wrong with your printer. If it printed out much smaller than you were expecting,...

    You're talking about building some kind of enclosure box? Sure, that's a pretty common use of 3D printing, although there certainly are other ways of doing that which might be quicker, stronger, or...

    If you already asked Crunchbase https://www.crunchbase.com/organization/botobjects you might try 3D Systems, which bought out the company (although I don't think it worked out for them).

    So once you build a new frame and install a new controller board, your old printer will be good as new? What's left of it, the hot end and belts? Both of those frames seem like something you could...

    There aren't too many printers that do a good job with multi-colors in the same part. It's usually better to make the main part with voids into which you can glue differently-colored parts that are...

    Maybe, but "derivative" works are still covered by the copyright. When you say "I want it to mimic it exactly" it sounds, at the very least, derivative.
