BOOM! Delta P Design Announces 3D Printed 50 Caliber Suppressor

In what may be a world’s first, silencer manufacturer Delta P Design has just announced a 50 caliber rated 3D printed suppressor. The 12.7mm (I’ll let you do the math) model is made with a proprietary inconel alloy that can withstand use on a variety of heavy machine guns.

Besides being beltfed rated, the 12.7 can withstand extreme temperature shock. For example, boat mounted 50 caliber heavy machine guns utilizing the new Delta P silencer can be run with a high firing schedule and still take a blast of cold seawater without failure.

Why suppress a beltfed fifty? Silencers can change the way gunfire sounds to the receiving party, providing an added level of confusion for the enemy. Obviously, these new models have some very unique and “special” applications, but if you are interested in one for yourself, drop Delta P a line.

Delta P Design


WALTERVILLE, OR, MAY 12, 2017Delta P Design announced today that it has developed a .50 caliber machine-gun suppressor to add to its BREVIS® II family of suppressors. Using state-of-the-art Direct Metal Laser Melting (DMLM) 3-D printing technology, the BREVIS II is manufactured in a single, solid piece of metal with no welds or threaded seams for failure points. The BREVIS II suppressors are smaller, lighter, and more durable than conventionally made suppressors and are therefore able to withstand the extremes of heat and pressure found in certain applications. Delta P Design specializes in these extreme-duty applications, such as Short Barrel Rifles (SBR) and belt-fed machine guns.

Manufactured entirely in Inconel (for belt-fed machine guns) or titanium (for bolt-action or semi-automatic rifles), the .50 caliber suppressor has demonstrated in testing its unique ability to combine shorter length, lighter weight, and superior durability than possible with conventional design and manufacturing technology.  Like the rest of the BREVIS II line, the new suppressors excel in all categories including both sound and flash suppression.

Leveraging the advantages of additive manufacturing and design expertise allows Delta P Design to overcome the challenges associated with these difficult applications.  The ability to effectively suppress weapons in the heavy machine gun role opens up significant possibilities for the application of these weapon system(s) on multiple platforms for customers.

Delta P Design is currently qualifying suppressors in this class with various customers around the world.  Delta P Design provides a full line of suppression solutions and specializes in quick turn development to meet unique applications.

Delta P Design has also announced a 9.5mm silencer:

In addition to the announcement of the new silencers, Delta P Design is partnering with i3DMFG in an exclusive agreement to build the next generation of 3D printed suppressors.


WALTERVILLE, OR, MAY 12, 2017 – Delta P Design and i3DMFG today announced their exclusive agreement to design and manufacture 3D-printed weapon suppressors using i3D’s Direct Metal Laser Melting (DMLM) technology. Combining Delta P’s extensive design expertise and i3D’s manufacturing technology, the BREVIS II suppressor line is printed in entirely one piece, with no welded or threaded failure points, providing superior performance, reliability, size and weight reduction.

Since the invention of the suppressor more a century ago, designs have been variations on the original theme, locked in and limited by manufacturing processes even older. They all have one thing in common—they are an assembly of many parts welded or threaded together, housed in a cylindrical tube—placing severe limitations on performance.  Since threads and welds mean failure points, virtually all suppressors require a quick-disconnect feature in case of failure, further adding to size, weight and cost.

Suppressors utilizing the combined 3D printing manufacturing and design expertise of i3D and Delta P Design are made from a single piece of metal.  This overcomes many of the restraints imposed by traditional manufacturing methods and removes the negatives imposed by multi-part assemblies.

Features are included that are impossible to make using traditional technology, resulting in smaller, lighter suppressors with improved performance and exceptional durability. For example, all-Inconel suppressors are now possible. Inconel is a high nickel super alloy with significant advantages over stainless steel for suppressor applications. The all-Inconel BREVIS II Magnum suppressors solve the problem of durability in heavy machine-gun applications.

The use of i3D’s manufacturing technology provides a fast turn-around from design to a CAD file, then directly to the 3D printing machine. This eliminates the time consuming steps of parts fabrication and assembly, and greatly simplifies the supply chain. Delta P and i3D specialize in rapid delivery of new designs to meet unique requirements.

“3D printed suppressor design requires multiple disciplines coming together,” explained Dave Strong, head of sales and marketing for Delta P Design. “In many cases, it is as much about development of the manufacturing know-how as it is suppressor design.  Delta P Design looks forward to working closely with i3D to leverage their industry leading capabilities and expertise in this field.”

“Designing suppressors for 3-D printing requires a sophisticated mastery of both engineering and physics,” added Chad Cooper, chief strategic officer of i3D.  “Both the innovation and the speed that is possible with this state-of-the-art technology would have been unimaginable to the prior generation of engineers. We literally can go from performance requirements and a CAD file to finished parts in a matter of days.”

The Brevis II family is available in a variety of calibers ranging from 5.56mm to .50BMG.

    Ooooh, the internet is gonna be sooooo salty about this.

    3D printed and it’s a 50 bmg suppressor. It’s like the two things people harp against the most. This is gonna be beautiful.

    • As I mentioned in the other article commercial 3D printing is a whole different level than consumer 3D printing.

      Besides if a 3D printed fuel nozzle can survive in an airplane flying an 8,000nm flight (and engine failures are a big deal for ETOPS certified aircraft), I think it can survive somewhat well on a M2.

      • iksnilol

        I don’t mind 3d printing. We have 3d printed titanium cans in Norway as well.

        It’s just that the folks on the internet love complaining about 3d printing due to being misinformed.

        • Giolli Joker

          I see the opposite: additive manufacturing is frequently hyped on the internet by uninformed people as the do-it-all manufacturing method, better than anything else.
          It is extremely interesting for limited series, complicated geometries and prototypes, it surely opens the boundaries of what can be done, but it is not magic and usually is the slowest process with the least performing structural strength.
          I guess that Delta-P could do the same with investment casting, but likely their production numbers are fairly limited to make DMLS more convenient, and the manufacturing process is a cool, modern marketing tool as well.
          I’m pretty sure it makes no difference for this product (meaning that I agree that the suppressor will do its job with no issues), but I wonder if they do HIPping.

          P.S.: article says “proprietary inconel alloy” press release uses a more believable “Inconel”.

          • That is very true, only a small percentage of items are worth doing in 3D printing. More often than not they can be made cheaper and faster using more traditional manufacturing methods.

            But to add one more item to your list, small batch (almost custom) items are another area that 3D printing can be beneficial.

          • Renato H M de Oliveira

            True today. Tomorrow, who knows?

          • Tomorrow: Flying Cars and Orion Slave Girls.

            Heck a decade ago I don’t think anyone would’ve imagined a 3D printed part being used in such a high volume and high heat location.

          • Giolli Joker

            Well, I said “limited series”. 😛
            “Small batch” is maybe more accurate, though. 😉

        • neckbone

          Ohhhh, what other cool stuff y’all have in that place you called Norway?

          • iksnilol


            Crapton of Mausers.

            I dunno, probably plenty of cool stuff that I never think about. Just like how people don’t think nothin’ of buying liquor after midnight.

          • B-Sabre

            Can we say “Moose test”?
            I saw them do a simulated car/moose collision at a test site, and that was, quite frankly, terrifying.

          • iksnilol

            Oh yeah, moose are scary. It’s basically an armored deer the size of a horse.

            + Those long spindly legs make sure that the body hits the windshield.

  • Younggun21

    I didn’t see an associated MSRP for any of these, but with just a very cursory knowledge of 3D printing and its benefits this should bring the price fairly substantially. At least for 5.56 versions or 7.62 versions I really have no comparison for .50BMG full auto rated suppressors.

    • When it comes to 50BMG, if you have to ask you can’t afford it.

    • neckbone

      They aren’t worried about price. They go after the .gov market.

    • B. Young

      $1400-$2200 for the under 50bmg sizes

  • Mr Mxyzptlk

    Does anybody know what suppressors the USMC use on their .50s? I remember in the press releases about 1st Battalion, 2nd Marines being equipped with suppressors it mentioned they would be fitted to everything including their HMGs but I have not heard any more about this since.

    • Friend

      I would bet money on Barrett, just b/c I wasn’t aware of any other .50BMG suppressors until now. If anyone has actual information that would be nice though.

  • Richie

    A 9.5mm you say, please tell me thats for .375 CheyTac

    • iksnilol

      Probably for H&H and Brenneke.

    • Pete – TFB Writer

      Sure is

      • Adam D.

        First I thought it was for 9mm, then I realised something was off.
        9.5 is .375 bullet diameter, that’s CheyTac territory.
        Once I’ve asked Delta P if they had plans for a 9mm can similar to the 5.56 Brevis II. The answer was a fairly certain no, but it wasn’t a definite no.
        Reading this article at first I thought they’d changed their minds… damn it. 🙂

    • SGT Fish

      375 socom too

  • Get over it Fanbois

    This would be more useful for a remote weapons station. Unless you want to be the sucker sitting out in the desert heat. But hey at least you got a suppressor for your M2.

  • What’s the dimensions on the .50 and 9.5 suppressor?

    • Pete – TFB Writer

      Both are 3″ OD and 9.3″ long.

      • And weight?

        • Pete – TFB Writer

          7 pounds, 8 ounces.

          (Forgot to ask)

        • Pete – TFB Writer

          I was completely joking. 57oz for the inconel version.

  • phuzz

    Surely the headline should read (slightly quieter boom) not BOOM?

  • Gus Butts

    Do they also sell threaded M2 barrels? 😉

    • jestertoo

      M2A1 comes threaded for flashider.

  • commonman

    Are not silencers and suppressors two different things? I was told this by a machinist who also said the crazy current prices will be dropping exponentially once the garbage laws go away. I don’t know enough about them so I thought I’d ask.

    • xlucine

      Same thing. Some people get upset when you call one a silencer because no firearm is totally silent, but Hiram Maxim (son of the guy who made the machine gun) called his a silencer and he invented the damn thing.
