This is a followup to my previous post on home additive manufacturing is changing the world: https://poal.co/s/3dprinting/84501

I want to further explain and maybe clarify my ideas.

  1. 3D printing is accessible. One can get into it for under $300. 3D printing does what is very difficult for the home machinist, it makes straight lines and concentric circles.
  2. These straight lines and concentric circles can be used in printed jigs for ECM. Now, for <$300 the home machinist can make complex forms, straight lines, and concentric circles out of very hard, high quality steel. This can also be done on aluminum, titanium, and superalloys. ECM functions independent of material hardness.
  3. Using their ability to machine HQ steels to thousandths of an inch, the home machinist can combine these into higher level tech like ElectroDischarge Machining(EDM). This would be simple to do on a small scale. Imagine a desktop EDM wire, able to machine 1' cubed in 2 planes, Y and Z. That's the beginnings of ultra high quality mass manufacture for what is probably under $1000 in materials.
  4. Combine these techs. Imagine the other ones that I haven't thought of yet. Would it unreasonable to imagine that in 5 years you have people building transmissions, simple turbines, and other extremely precise and heavy duty machines as hobbyists do with simpler things today? I don't think so. In fact, I'm going to work to facilitate it.

The question still remains, do most people know what to do with this stuff? Do they understand how the disparate pieces fit together? No, not really. People are printing Deadpool busts out of carbon-filled nylon. They're wasting it.

But those few who do understand? Well, with the fantastically lower barrier to entry that I predict, you might see a "Glock" or "Benz" in every town. I expect the cottage industry to rocket into the high-technical and for mountains of open info on manufacture processes to be shared freely by Makers. I expect rapid and gleeful innovation on existing, open designs. What the internet has facilitated so far, it will continue to in the future. I expect .

Besides the small glimpse I have of the future, I cannot guess what else we'll see. However, my team and I are now working on a project to bring attention to this series of manufacturing steps. The great leap that can be made by the home machinist.

The problem with 3D printing, is that all the hobbyist gurus online are completely clueless. My buddy is a manufacturing engineer, specializing in plastics, and he bought a cheapo 3D printer for maybe $200, and had that thing printing better than many of the gurus with their $10,000 printers. He looked at their advice, and their advice was generally "Replace parts until it starts working!" and by then end, you just have the same $10,000 printer the gurus had.

I asked my friend why he wasn't trying to help people, and his response was basically "I'm one of maybe a dozen experts in the world in this topic, and paid damn good money to become said expert. I'm not giving away my secrets for free" So, until an expert who's more charitable than my friend comes along, the 3D printing culture will continue to have a huge barrier of entry ($10,000 printers, struggling to print crappy Deadpool busts)

The future will be just submitting a request and the AI takes it from there. Fully automated 100% of the processes. Your product will be ready in X minutes.

My vision of distributed industrialization will be realized before AI has the ability to do that. In fact, it may be a prerequisite.

People who say that 3D guns is why they like it never made a gun ever even when 3D printers were not needed.

I don't think you understand what exactly I'm talking about.

Home manufacturing, working with our hands to make a living, is predicted. We should all get back to our talents per Q and team. Garage mechanics, artists, etc. 3-d printed is a skill you can sell the product.

I just thought of something, we will have no more corporations, because they are evil and will be eliminated to some degree, for poisoning environment, citizens, taking their homelife away by slave like loyalty to put corporation above family in time and energy. Demanding they move around the world, separating them from supporting families.

I could go on. I like your vision of using modern tech to support ones self. We will need experts to teach other how to use these modern marvels. Do you teach?

Fucking gay. I embrace my own abilities without needing to be told to do so by some retarded hope-porn cult.

we will have no more corporations, because they are evil

They are evil because of the centralized power needed to produce hundreds of thousands of something and ship it all over the planet. This sort of centralized power will attract blood thirsty semites and other roaches to megacorps and make them fully evil instead of simply kind of evil.

Don't get me wrong, I'm still into the idea of specialization. People are best at certain things, however these idea, by lowering the barrier to entry of high-level production, can decentralize power. I still think people will trade with one another and do what they are best at, but there will be more localized supply chains for goods and more of a variety of them available.

I remember this happening back in 2013.

Solid Concepts states that the gun was printed with an industrial printer, the price of which is out of the range of your standard crazy person that would print a gun to mug you or rob a convenience store.

What I'm talking about is going to be far more concerning to normies. Paired with printed AR lowers, I think it would be possible to use only 3D printed jigs to Electrochemically Machine steel into a working, roller delayed upper. This would make it the first repeating rifle that could entirely downloaded. A true blow to bread and circuses.

Great. Now how do we 3D print bullets?

[–] [deleted] • 0 pt

Bullets are simple. Cast pot metal will do. The brass/steel cases are the hard part. However, with further exploration into this topic and some expertise in metalwork, I don't think it unfeasible to say we could start making casings on this small a scale in a few years.

I've looked into it.

The hard part (or what I think is the hard part), is making the gunpowder and primer. Black powder can be made from obtainable ingredients in a ball-mill. But the primer seems a bit harder to make. If you're in a country where bullets are fairly easy to obtain, it's probably easier to buy from a store. But in other countries, not really.

I'm not sure if the materials can extracted from ramjet tools. That may be another possibility.

Disclaimer to all the glow in the darks: I'm only curious into how it would be done for educational purposes and mental masturbation. I don't intend to ever make these if it's against the law, as I'm sure everyone else in this thread is also never going to make these.
