I suspect that the bulk is plenty strong but the side of the bedding/engagement area would make or break the design.
What type of shotgun?

I would expect the cost of 3-D printing a gun stock would far exceed the cost of a stock made by any other superior method.
What would the total cost be to print something that large???

It would come down to the design and the exact material. There's a dozen or so common 3D printing materials, some of which are brittle, some of which flex or warp too easily, and some which would work fine. You'd have to figure out which would bind with the wood.
Also, a shotgun stock might fit in the usual work envelope, but some styles or a rifle stock would need a big, expensive printer.

Probably the best way to use a 3D printer for stuff like this would be to "print" a mold and use it to cast your resin and wood mixture.

I don't know about wood resins, but I've printed a combined pistol grip and stock from ABS, and it works pretty well - no cracking or warping at all.
The printing costs themselves are almost negligible, it's the printer that costs a lot.

Can't have an adjustable comb and butt pad installed that would work?
Otherwise $2500 buys a lot of stock unless you are looking for top tier grained walnut.
What caliber did your pistol grip stock go on?
I wish it did. It needs to be custom made (Perazzi MX-14...) with a 1.25"(If I remember correctly) stock offset.

Did you contact Perazzi USA? If you bought the gun new, you had a chance to have it made to your specs for no additional cost. Otherwise, contact someone like S&S in MT.
I bought it used. I already have a professional fitter (who has does work for olympic teams).

Hobby grade 3D printers using ABS doesn't yield a particularly strong product. It is nowhere near the strength you get from injection molding, and even then, ABS would be a marginal material for a shotgun stock.
You would be a lot better off hand carving it from a chunk of UHMW polyethylene.

The only way ABS would be used would be to make a mold and pour in a wood&resin mixture. Otherwise I would use a more sturdy filament.

I misunderstood what you were saying. The recycled wood would have to be a rather fine particle size to fit through the 3D printer extruder, but if you have suitable filament and a printer with a large enough build area then it should work if the filament material has adequate strength for the task.

Are you talking cast or drop? If you need 1.25" of cast, it seems like you are cross dominant and shooting off the wrong shoulder.

What are you going to use? Most of the homeowner grade printers aren't able to do Nylons and the like.
I am not cross-eye dominant, or shooting off the wrong shoulder. This cast is to get my eyes level & not at an angle.
They make filaments that require a certain bed temp and extruder temp, both of which my 3D printer will be able to handle. Although, I think I may end up doing a mold and pouring a sawdust and resin mixture because it would be easier.
There's no way to answer that question. It is similar to asking if I make a chair out of 40% recycled wood and binding polymer will it work at the bar? You have to specify the materials AND the design to have any meaningful starting place.
While I can't you a specific design (I have not had the time to model it), here is a basic design that I will be copying and adding 1.25" offset to the right.

There's nothing particularly intricate about that; why not just carve it from a hunk of walnut?
Personally, I think even if a 3D printed polymer were strong enough (doubtful), it look like excrement on that gun. Even a crude wood stock would have more pleasing aesthetics than the visible matrix of melted filament composing a larger piece.
Ok OP is not an engineer. we know this 'cause he's posting here. That's Not. A. Problem. He's a gun guy like the rest of us. Why shoot the idea down?
OneWound: make it and shoot some slugs until it breaks. Then redesign and make another. That's the beauty of 3D printers. Maybe some extra reinforcement in the curves and possibly copy some of what they did with the non inflatable tires for the Humvee for the recoil pad? I dunno. Build a dozen standard 870 stocks based on your design and find a few guys like Dave McCracken (God Rest His Soul) to send them to for torture testing. Ok. Maybe there are no more like him, but still...

Kinda like buying a Ferrari and complain about the cost maintenance don't ya think?
