the big problem with that is that this is a messy process, any machined surfaces would need to be able to be masked or cleaned up later in order to keep any slag or dross from sticking to it

the only place it would make sense is on mars or x - planet

the only sense it would have on earth is as a corection technique , mistake no problem just add material and mill it again

@@easternperspective0244 Not really, you can use it to create internal, unmillable geometry lol, its not gonna replace milling, but it will replace some advanced and difficult processes for sure.

CAN YOU TELL ME IS IT AS GOOD AS A BILLET PART CNC

@@tonyking9235 it's even better if you can't make that part on a cnc in the first place

Think of all the times people have said "you can cut metal off but you can't cut it back on".

@@domakent I took some classes in CNC and I laugh reading this because I professor swore by that BS. I told him that in the near future there will be machines that add on and take away. I said "if you can only take away and not add on, you're the devil; but if you can do both, you are God."

😂😂😂😂😂 still hearing it I might have to correct the next person that says it though ​@@domakent

Almost zero waste. 75% of machined blank would wind up on the floor and maching would need to be from both sides as the part is hollow. Fusion may be a bonus as the grain direction is not uniform.

@@IanM-rl1pu You can cast a blank to closer accuracy than what they are machining off here and do it faster. Car turbos are cast and get a quick run under a grinding/polishing wheel for surface finish. Precision casting gets 0.2mm accuracy for the first 10cm and +0.1mm per 1cm after that. So most items would need no more than surface finishing. I think AM only makes sense for parts where you don't CNC after and need shapes where you can't fit a cutting head. Injection molding has been 100% automated, and many things don't need much or any surface finish after. These welding methods are way too slow compared to laser sintering, and most additive processes are extremely energy inefficient. If there was more vertical integration so that there was smelting and casting in one factory you could save 2-3 melting processes and go directly from refined steel into a molded product. THAT would be a revolution. Instead we are focusing on Smelt -> Cast -> powdering/roll into wire -> melt with laser/welder. Each time using tons of electricity and fuel because everything is spread across multiple factories.

@@excitedbox5705 you said a whole lot for an idiot. First off the product end quality and properties will be different with every method you just described. And additive manufacturing is inherently stronger than cast or billet or injected it will have more in common with a forged billet method. This is clearly a turbo pump for a rocket& cast automotive pumps would grenade under rocket conditions.

@@excitedbox5705 Every method of manufacturing has its benefits and limitations. Casting is great when you have a foundry and lots of somethings to do or massive somethings to do. For one turbo its not worth making the blank/dummy to cast the sand. When the term Hi Production is used to describe an n.c. it means hi precision fast & efficient not progressive die part number productive. This is a super car. Able to work within .0002"( 1/16 of a human hair) compared with the.008"(two fat human hairs) on your casting plus all the other geometrical constraints that can't be attained in casting. ( two tenths with with temp control coolant and ambient air.) Casting is a western star. great for volume and a process that runs best when never stopped. Too expensive to fire up again. Think prototyping. Foils for jet engine compressors. model-machine- test- modify model-make new-retest by the next morning. That's where this machine will thrive. Problem is, what are the metallurgical speed bumps? No tool steel, the aluminum alloys are likely no go definitely no magnesium. This is where my questions lie. cheers.

I think machining from a solid billet was a better option for this case of an impeller. Additive manufacturing and other traditional processes shall greatly supplement each other to deliver products we could only dream of.

This is no conventional 3D printing. Note that there’s little to no support structures being added during the process. With the fact that this machine is able to work with almost full range of motion and different types of manufacturing tools, I would say it is a work of art.

@@mariotonizza3411 I'm just wondering why they 3d printed this part instead of just machining it from a block of whatever. The only reason to print is to make features that are impossible to machine and all of that part looks easily machined.

@@jerryherrin6470 No, it's to save on material costs as well. The machine is likely _very_ expensive, however if it performs well and doesn't cost a fortune to maintain and run, then it will be paid for in savings from using less material. What you saw here is the equivalent on skipping the roughing process, which would likely have subtracted as much or material as remained in the finished piece.

Machines like this are actually somewhat poor, you end up with a fair bit of porosity due to the powder not melting properly.

@@samengel6866 I knew that!!!… Me, as a CNC machinist, ain’t going to lose my employment anytime soon. I operate metal cutting CNCs, not 3D printers.

Y does Japanese have anything to do with it?

@@the_larsonfamily because it is a japanese company (dmg mori seiki), dmg is just the european subsidiary of the japanese mother company.

@@tengilaurel3777 i think the lasertec stuff is located in Germany...

@@themechanix393 You can't generalise this anymore. It's not a file or a screwdriver that gets sourced and manufactured in one country or location. Specifically the Lasertec Solutions are based on international researches that exceed the capabilities of one nation alone. Even the production of the machine tool itself is outsourced to global subcontractors. Some machines are "made in Germany", some are "made in Japan" or elsewhere. It doesn't matter. What really matters is the outcome of this whole conglomerate of genius. A magnificent machine that strive to revolutionise production as we know it.

this machine was built and engineered in Germany

It is in fact japanese technology, dmg mori is a japanese company with its headquarter in Japan.

Exactly

I think you'd need more than one for one of these bad units

Yes definitely, That is actually one of the most common use cases
