Of all the variations of locomotives I’ve had rendered for me lately, this one looks the most feasible.
Prompt:in a convention center, parked in a display booth is a half-scale locomotive made of brightly colored, mismatched parts 3d printed and fit together like a puzzle. it has the headlight lit up, and smoke billowing from the smokestack. people are gathered around admiring the awesomeness of the locomotive
Other iterations
Yeah, especially this one
That huge plume of smoke is apparently a single 3d print, and the whole thing looks to be made of big prints done fast and sloppy on an enormous printer. Anyone who built a machine capable of that would surely use the train as an advertisement for their product!
And yes, I do imagine that it would take weeks and weeks and hundreds of pounds of filaments to get such a thing printed, even with thin walls and minimal infill.
I’d think many of the apparently single pieces would be glued together from several prints in the same color.
