If this guy were to make crossbow shells they wouldn't be that sturdy due to layering
We might as well factory mold them for stability, (cough orangemodworks ,cough).
That's not entirely accurate for the process this printer uses. Some 3d printer technology makes parts only suited for non-functional models , but FDM (aka FFF) is not one of those.
The parts aren't quite as strong as injection molded parts, and it's true that the parts are weaker in the Z axis. However, they are still very
sturdy. The parts can also be made to whatever thickness you want, so could easily be designed to be have more strength than a 1:1 crossbow copy. Also,for what it's worth, all the major loads in a crossbow would be distributed along the strong directions of the print (not that I want to print crossbows)
Really, the thing preventing me from running out and designing a pile of stuff to sell, is the time it takes to print things. To make a reasonable rate given the cost of the printers, it's still $10/hr to make parts. That is still a bit out of reach for many hobbyists.
If you have got/bought one to play with and don't have to support yourself making money off it, that is an entirely different story.
But as I said before, once these become more popular all the costs will decrease further and within 5 years they will probably be as common as band saws and drill presses
