  • part of the problem with that is that most of your ghost guns are “just” the AR 15 lower receiver- the part classified as the “firearm” because of some technicality only a lawyer can understand.

    It’s not a load bearing, nor is it exposed to any particularly high levels of heat, nor any sort of particularly nasty gasses. So that can be printed in just about anything if the printer’s resolution is good enough. (IIRC, they typically call for resin printers.)

    Then, the ghost gun peeps just buy the rest of the components retail and pay cash.

    for fully-printed firearms, you’re looking at things like DMLS or other kinds of precision metalwork. It’s the kind of work that would be more expensive than roadtripping to arizona and getting loophole-gun.



  • What exactly are you asking?

    It’s pretty easy, for example, to turn an image into a grayscale .bmp and convert that to an elevation map that roughly creates an embossed/engraved surface.

    It’s not easy to take photos of objects and turn them into 3d models of that object. It’s pretty much impossible from a single photo, as well. It’s possible, but usually fairly complicated- it’s called photogrammetry and there’s tools and plugins for blender that can do it; but it’s very hit or miss.


  • I 3d printed most of the bits for a Kosh Naranec costume. he could be a court magician… and it would still fit with the lore in bab 5, too. (oh. you said you don’t want something over the top…sorry. the best part is you can set up some motion activated light shows and play his various enigmatic one liners, stand the thing up in a corner and go get a pint someplace else; without ever leaving character. The avalanche has fallen. it’s too late for the pebbles to vote.)

    alternatively you could do an “actual” court magician. or something to that effect. 3d print baubles and a top to some kind of staff. generic robes in black with a big baggy hat to round it out. learning some slight of hand might help sell it.













  • No.

    • energy requirements will always be higher vs surface transit

    • mechanical complexity will increase mechanical failures. these mechanical failures are much more likely to lead to death or severe injury or extensive damage.

    • you think self driving is bad now? It’s not. Planes can largely fly themselves, but that’s not the hard part. It’s the everything else, including maintaining safe patterns and separation. If everyone jumped to air travel in a city congestion just moves into the air, and you’ll have shit loads of accidents. Throw in improperly maintained air craft because that shit is expensive and you have a recipe for 9/11-level accidents on a daily basis.

    Mass transit is the way to go.
