This is very interesting to me. Does that mean you can make bumpers and stuff? Or just like little accessories? I would be very interested if that is possible.
But what company do you work for? How much is a 3D printer regularly cost? |

When we upgraded printers in the middle of last year, we had an option to get a machine capable of printing up to 24x36x24 if we were willing to drop something like $250k on a machine. The handful of those that I know of (last I checked there was only one in the NJ/E. PA/NYC area, but a bunch in the midwest) are most often used for production tooling, or making low-medium volume production parts. (Specifically Half Fenders for Trucks) TLDR, it'd be tricky to make a bumper, but if the operator knows what they're doing and has the appropriate CAD software, it's difficultly will more often than not be determined by the consistency of the machine, rather than the size of the part(s). In the specific case of a bumper, where the part thickness is rarely going to exceed 1/4", I'd probably project the geometry into some rectangular volume of known size (est 24"D X 24"T X 66"-72"W) to get a good negative (or positive) of the finished part I'm shooting for, and then break that rectangular volume into a series of 'puzzle pieces' that can be printed with whatever machine I'm working with. That sort of method might use a bit more material, but the odds of the final assembly being right the first time is probably 10-15X what it would be with another method. (It also gives you the ability to make a series of modular molds that utilize constant geometry for certain parts (lights, license plates, etc) and then change out the 'aesthetic' bits. |
