3D Printed Stock

[CharlieNC]

Saw this today on Rimfire Central, the OP made this 3D printed benchrest stock. I thought this was quite innovative and wondered if anyone here has been experimenting with similar applicatons?

Looks pretty cool to me, I think this will evolve into something even better over the next 1/2 dozen or so he makes.

How much flex would this these stocks have if used with center-fire cartridges?

That's pretty cool.

Additive technology is the future. My son and I have a little 3D printer and I have made a couple target prototypes on it.

It depends on the plastic filament that is used. ABS is pretty stiff but requires some extra care when using it.

Most plastic stocks, like the KRG Bravo, have an internal aluminum structure to add stiffness.

Several years ago I saw YouTube's of buildings and homes built by 3d printing using concrete over rebar, including interior walls. Very little human labor involved. Many plastics, elastomers, and a few metals are available for hobbyist and it is a growing segment for rapid prototyping and manufacturing too.

I'm not sure of who it was as I wasn't at the match, but last year at a match in Seymour, TX. I heard that there was a guy with a 3D printed stock, I don't recall how well it worked out but it would have been a HV match at 100 & 200 yds, probably a 6PPC but again, not 100% sure.

There’s a lot more to a stock than just shape. Flex is important, but so is balance and vibration absorption. I’m sure I sound overly critical but a cheap Chinese toy comes to mind.

I'm not sure how he did at Seymour, but a few weeks later he shot a 250-23X at the 100 VFS match at ASC.

Hi I'm Jim Nicolas the guy at Seymour last year. I have been developing 3D printed rifle stocks for a couple years now. The orange Heavy Varmint (HV) on the left was my first functional prototype, the red one on the right is the a Light Varmint (LV). The HV shoot lights out and I won at VFS at ASC three of four times last year with a 30BR barrel on it.
I didn't have much luck at Seymour match last year, but I did manage a small group in one of the matches. I only practiced once with it and then the match. Unfortunately I have not shot anything since due to medical issues.
The black stock below is an ultra light stock weighing 17.9 oz painted. This allows the shooter to have BAT-DS action (or other), 15-55 variable night force scope, and still make the LV weight limit (10.5lb).

The rifles are made of engineering grade carbon fiber material using a high temperature, enclosed 3D printer. A vibration reduction system is integrated into the stocks to dampen higher order modes which significantly improves tracking for LV rifles.

What would it cost materials wise. Carbon fiber isnt cheap.

I remember that stock well from last year‘s Seymour Match.

Congratulations on your 23x effort at ASC.

I will be at Seymour this year. I will shoot my Rail Gun in 6PPC in Unlimited, and probably my 30BR in HV.

I did pretty decent with it last year.

Hi Jackie - You always shoot good, and I hope to see you there.

I've got a bud in Idaho that is printing inconel for rocket "exhaust" and race car headers.
Look up Brian Haack on facebook. Brian made a few 10-22 receivers in the olden days that allowed you to position the trigger assembly to shoot either 22LR to 22mag or their 17 cal things. He offered the bolt for the 17HMR with a tungsten insert.
Your stock and idea is great Jim.

He's a good friend of mine and is in the testing stages. It looks good from early testing.

From an additive manufacturing perspective, there’s a bunch of appealing features that can be used to develop very complex shapes with reinforcement only where required.

Continuous filament fiberglass or carbon fiber reinforced plastics are available for printing these days, though more in the commercial sector.

Random direction reinforcement like in most carbon fiber filaments these days is also probably suitable with the right fiber size, plastic stiffness, and layer adhesion.

The process I would use is called “remelting”, in which you cast your plastic in plaster and heat it above its melting point to create a solid part. Think of it as cheap injection molding.
