Re: Practical 3D printed parts
Just in this one picture there are many 3D printed parts: - wheels on end of arm that set floor height. - bearing blocks on active leading edge (inside wheels) - finger grippers on 3/8" round, keyed shaft - crowned flat belt pulley on keyed 3/8" shaft (under flat belt) - finger grippers on 1/2" hex shaft - bearing blocks on main arm pivot - drivetrain gearbox dust covers (near side yellow, far side purple) - camera/light ring mount (purple, on underside of shooter) We're to the point now where we'll make just about any nonstructural part with the 3D printer rather than spending fab time to make it. Thus far, we haven't broken any plastic parts. The bearing blocks were an experiment to see if semi structural parts could hold up if made beefy. These have lasted through two off-season competitions and at least half a dozen demos. |
