haha Very true. Back in the day you had to be cool enough or lucky enough to be around such people but now KZbin lets everyone in!!

[@sasjadevries]

Yeah, well, kinda. Most shows on youtube that are supposedly scientific basically don't tell you shit. Steph at least shows you the whole process of the build, which is great, but he doesn't show you the designs process, calculations, tuning, etc. The good thing is that this kind of content is understandable for everyone (even outsiders to tuning) and it's still nice to watch even if you're into tuning yourself. This is valuable content, I like it. But still I think he isn't sharing a lot of knowledge with us in terms of specific details. Why? Because I have seen how generously Russian youtubers share their knowledge. _"So I have ported the intake to 26mm diameter, at the valve guides it's 27mm, where the ports come together it's ported to 37mm, I only polished the top side because the bottom side has will have slow separation and therefore a rough surface is preferred"_

[@kiyoponnn]

@@sasjadevries Why would he share detailed knowledge? It's an important part of his business and he would lose money by doing so

[@sasjadevries]

​@@kiyoponnn It depends on your business model. And sharing info actually makes a ton of sense in quite some cases. If you are open and honest about your setup, then most people will think: _"hey, looks like you know what ya doing, can you tune my car"._ Such a honest approach and open attitude can bring in a lot of customers. In practise it's the charlatans and noobs who don't want anyone to see how they get their job done, because they're bad at it. And then there is the difference between knowing what should be done and actually having talent doing it. Telling someone how it should be done doesn't mean he will succeed. One great example of this in autosports is "Gocha", from the beginning of his career he has been sharing info about his setup _(including precise camber angles)_ with anyone that's interested, dozens of engineers from Europe and Japan have examined and photographed his car; and guess what: he became drifting world champion *again* in 2019.

That’s an “older” printer too they are getting really good really fast

[@alexcecil89]

@Kevin Schmidt can be done with any metal. titanium especially, because its so hard to machine or form, and an expensive materia to waste so much during subtractive manufacturing. its getting to the point where its gonna be cheaper to 3d print titanium and other exotic metals, rather than create a part out of billet via subtractive manufacturing

[@treverfogarty8514]

Kevin Schmidt It’s basically just Percision welding so if the medium (powder) is available they can print it.

[@Motor-City-Mike]

G.M. has been 3D printing of prototype intake manifolds since the 1980s. At that time I was an instructor at a local college and G.M. donated what was then called a stereo - lithography machine to the college. The media was a resin compound but worked well for prototyping low stress components.

[@meantforu222]

[@W-H1U]

i read that in dr evil voice hahahahahah

[@68pishta68]

Stereolithography. Been doing plastics like that since 1986. That was even more complex: The laser focus was fixed right above the pool of resin and a bed would break the surface and get lased wherever it needed a build up. then it would lower 2-3mm and rise up again (minus the height of 1 layer) with a fresh layer of resin on top of the last layer...lase that layer...on and on and the machine would have to wait for any waves to stop in the tank so it was an overnight process for a few inches but you could build a furnished doll house a layer at a time. Now they are doing it with aluminum powder. That is some one off stuff right there as the cost to 3D print a form for a custom AL casting would be cheaper and maybe just as fast if you had the production nearby waiting for the part.

[@fendergtr]

[@afrozen10-02]

Fun fact: I’m currently working on a project at my university that’s looking at speeding up the build time of those 3D printers by increasing the thickness of each layer. The only issue is that increasing the layer thickness could introduce porosity which would lead to mechanical deficiencies. It’s really cool and I’m really happy with the exposure this kind of printing has been getting recently.

[@soaringvulture]

The other issue is that increasing the layer thickness reduces your Z-axis resolution. It also slows down the process because you need to scan the laser more slowly to melt the increased volume.

[@paulbains9152]

In ceramic shell , some times we got porosity . You have so much time in the part , you try and save it . You can paint the runners inside with Devcon Liquid Aluminum Epoxy , never had a problem with it coming off , if applied to a new part .

It was by 1980 - I remember because I was working in the business hub of Toronto for a mining company that makes fine metal powders like nickel and cobalt for tech leaders like GE's jet engine division. In our office tower there was an architectural firm that was modeling proposed projects, i.e. those miniatures of office towers you'd see in lobbies. They had something that would lay a non-metallic powder and follow that with an adhesive to bond it where desired, then go up a level and repeat, etc. I thought it was a nutty way to make a model but who's to judge. That would be the grand daddy inception of powder deposition. Early 90's I paid $625 for a Creative Labs 3X speed CD writer to be able to tell customers we could burn CDs for them. Slow as molasses but the first on the block. I paid over $300 for my first DVD burner a few years later (~1995) and it wasn't even 5X write speed.

[@Hydrazine1000]

No, it's not sintering anymore. More than a decade ago or so, 3D powder metal printers would rely on SLS, Selective Laser Sintering. With the advance of optics and increase in laser power machines moved to SLM, selective Laser Melting. As mentioned elsewhere, modern machines can still do sintering when porous parts are required (say, filters). The difference between sintering and melting is that with the former you don't exceed the melting temperature of the powder, the particles just get hot enough to soften and stick/fuse together. You can get up to about 95% density this way. With SLM it is possible to truly melt the powder and get to 99.95% density.
