One thing about the new technology though; yes, it has big capital costs, and is not necessarily faster; but it reduces labor. 2 maintainers, 2 programmers, and a couple of extractors/material handlers can produce a lot of parts. CNC equipment isn't cheap either, when you look at it. So advances in manufacturing can help make better weapons, or at least free up labor for other uses.

The same number of people can service and entire factory hall full of CNC automats and pump out thousands of parts per day.
Additive manufacturing doesn't need much manpower but is much much slower than other methods. This is the problem. For the same cost in machinery and labor you get thousands of parts against a couple of dozzent in one day. Additive mfg only makes sense if there are benefits that can only be realised by these techniques.
Its also simply not true that something build with new techniques is automatically better than something build with traditional ones. It might be. But the quality of a product depends conciderable more on design and development, how production is organised and quality controll than the mfg methods used to build it.

For example a very good method to manufacture large quantities of high quality sectional steel is extrusion pressing. It would make lots of sense to design a GPMG with a receiver made this way. It would be comparable light but tough. Better than steel stampings. The method is cheap and fast. Way more efficient than any form of chipping production method.
The resulting weapon would have the potential to be tough yet lightweight, easy to mass produce and thus cheap.
No new technology needed. Just apply widely available industrial standard. It just has to be done.

But IMHO the question is if a LMG is really needed in mech inf squads if a SAW is available.

What is the distinction?

LMG is a machine gun primarily intended to be fired from a bipod and carried by infantry. This is a mechanical distinction of design.

A SAW is basically whatever a military chooses to issue to infantry squads as their primary source of automatic fire. This could be a LMG (M249 US army) a GPMG (MG3 Austria) or an automatic rifle (BAR/M27 Marines.) So it’s a matter of usage rather then design.

At least that’s my take. 

I asked that, too.  His distinction is @ https://forums.delphiforums.com/autogun/messages?msg=7720.280

Sorry, i am lazy.
If i am refering to a SAW i mean a SCHV, belt fed on bipod.
While an LMG is a full caliber machine gun on bipod.
Using two three letter abbreviations is very convenient.

yeah, just trying to figure out terminology. SCHV?

small caliber high velocity.
I though this one is common knowledge. Sorry.

Extruded MG receiver? I like it! 

One thing about AM, though. People are, for whatever reason, willing to accept products made from it than other methods. "This has MIM parts". And do I really need to bring up some reactions to castings? 

Hopefully we'll see improvements in "acceptable" technology for weapons production.

Extrusions are great.... Almost sounds like you guys are inadvertantly describing the ots-128 in 7.62 NATO here.

According to the website "soldat-und-technik.de":

Today, the judgment of Düsseldorf High Court (Oberlandesgericht) had been scheduled to be handed down.

Instead, the court decided that it needs to re-enter into questioning witnesses. If I understood the legal language of the courts public statement correctly:

The court was informed that Heckler & Koch, before the German Patent Court, changed its way of arguing to defend the validity of its scupper (thats how I call it) patent. This is the patent allegedly infringed by the Haenel rifle candidate. 

The court sees the change of HKs position regarding the patent as substantial enough to re-discuss the matter in court, among other things re-assessing the chances that the scupper patent can be upheld at all.   

P.S.: For those who wonder: a scupper (German: Speigatt) has been for centuries the way Navies got rid of unwanted water on the deck: let it flow back into the sea through appropriate holes.
