There were two links posted - I notice you're completely ignoring the second. There are also other kinds of 3-D printer, and different types will be invented. Can you honestly not see that, or are you just ignoring it, because you know you've lost this particular argument?

I see you are ignoring the close up photo showing that what I said is true. And again, there is only one type of 3D printer; a machine that takes a material that has fluid properties and deposits it in thin layers which are then hardened. It makes no difference if the material is thermoplastic that has been heated and then allowed to cool or micronized metal particles which are then sintered together with a laser or electron beam machine. -- Jim Pennino

Don't be silly. Neither traditional laser sintering, nor the other technology I cited "squirt out something that has liquid properties" unless by "squirt" you mean "pump" into a tank. They are very different to a movable head which deposits material in a 3-D pattern. > >>>> Second, even something as simple as adding more print heads would multiply the >>>> printing speed, as I've explained twice now. >>> >>> What part of we are already at the limit of deposition rate is it you can not >>> grasp? >> >> The part where you saying it makes it true: it's not. >> Unless you can prove me wrong, it's your claim after all, so feel free to >> provide evidence. > > What do YOU think limits deposition rate, the speed of stepper motors? Yes; and we're nowhere near the limits of those, the deposition rate FOR THAT KIND OF 3-D PRINTER, and multiple printer heads would solve that because, hardening time is not at its upper bound yet. >> There were two links posted - I notice you're completely ignoring the second. >> There are also other kinds of 3-D printer, and different types will be invented. >> Can you honestly not see that, or are you just ignoring it, because you know >> you've lost this particular argument? > > I see you are ignoring the close up photo showing that what I said is true.

Just not true. FFS neither of the other two kinds of fabricator I mentioned work in that way. Read the article!

FFS neither of the other two kinds of fabricator I mentioned > work in that way. Read the article! Since you are such a dense littlt twit, I will type slowly so that you may understand. A 3D printer consists of 3 primary system: 1: The postioning system. This is the part of the machine that moves the deposition system, what ever it may be, around. This system is decended from XY protters and NC machinery, technology that is over a half century old and fully matured shortly after the microprocessor became commercially available over 40 years ago. 2: The deposition system. This is the part of the machine that deposits the material being printed, whatever it may be. All deposition depend on the material having liquid properties, at least for some time. For thermoplastic printers the solid plastic is melted in the deposition system and applied through a nozzle. For metal printers, the solid metal is in a micronized form such that it can be forced through a nozzle of some sort. The metal powder may or may not have a carrier material added to make the process easier. There is no way to "print" a material other than to squirt it in very small quantities (assuming one desires some sort of accuracy) out of a small oriface of some sort. The accuracy of the final printed product is directly related to how small an amount of material can be deposited at one time. 3: The hardening system. This is the part of the machine that hardens the the printed material. For a thermoplastic machine this may consist of nothing more than allowing air flow around the printed such that a given print pass can cool before the next print pass is applied. For a metal machine, there are several hardening methods, such as laser and electron beam sintering. -- Jim Pennino

Since you're still ignoring the system I cited, let me explain *it* to you: polymers are pumped into a tank, a laser scans it, hardening it in places. Note there's no moving "deposition system", just a moving "hardening system". Obviously, the speed of operation depends on the rate at which polymer is pumped in, and the rate at which the top layer is scanned and hardened. This depends on the intensity of the laser, and the number of lasers, in theory you could have dozens. This would, obviously, make it faster than a single head; which is already the fastest 3-D printer in the world. > > A 3D printer consists of 3 primary system: > > 1: The postioning system. > > This is the part of the machine that moves the deposition system, what ever > it may be, around. > > This system is decended from XY protters and NC machinery, technology > that is over a half century old and fully matured shortly after the > microprocessor became commercially available over 40 years ago.

Just watch the video: http://www.popsci.com/fastest-3-d-printer-ever The laser scans the surface of the material, from below.

I know you won't have heard of it; but there's this thing called adaptive control; and you can use it to raise and lower the plate below which the material comes so it's at precisely the right height above the surface you're building on. I know, right?! It's also very fast, obviously, even when I first started working in embedded systems 35 years ago, we could drive a hydraulic chisel over a surface at 5cm/second with sufficient accuracy using an 8-bit processor running at 16MHz. Things have rather improved since then. >>> The accuracy of the final printed product is directly related to how >>> small an amount of material can be deposited at one time. >> >> As you can see from the above, this just isn't true. > > Change the above to "deposited or hardened" and the problem is fixed. Nice to see you actually learn something.

You referenced the Wikipedia article. Did you not read it? You really should. We can 3-D print *right now*: Thermoplastics, eutectic metals, edible materials, Rubbers, Modeling clay, Plasticine, Metal clay (including Precious Metal Clay), Ceramic materials, Metal alloy, cermet, metal matrix composite, ceramic matrix composite Nylon or Nylon with short carbon fiber + reinforcement in the form Carbon, Kevlar, Glass and Glass for high temperature fiber Photopolymer,Photopolymer + thermally activated chemistry Almost any metal alloy including Titanium alloys There's duplication; because I can't be bothered to edit it, knowing you'll ignore it anyway. To be fair, most of these are industrial (not all though); but then, as you're aware, many things in the home started out industrially. So, no, it's not beyond the pale. SpaceX has already flight-qualified a rocket engine made using direct metal sintering, so an internal combustion engine is possible, although by the time one can, I suspect one wouldn't - preferring to use electric motors in wheels. Which, yes, could be made using fabricated components.

People literally buy millions of >items made out of aluminum and plastic every day and throw them out, the >material is so cheap. The amount of aluminum in a soda can has decreased dramatically over time. I remember seeing an article on can engineering in SciAm twenty or so years ago. It's probably halfed again since then. Cars once had frames under the body. Now, carefully shaped bodies serve the purpose that once required a frame. New technologies can dramatically reduce the amount of aluminum or plastic that you require to do something. You can overdo it. My mother believed in bulk purchasing and in having suitable treats on hand when the grandkids arrived. When preparing the estate, we discovered a five foot stack of soda in one of the closets. One flat (24 cans) of Costco "Simply" cola had pinhole-ruptured almost all of the cans, but had leaked slowly enough that nothing sprayed and nothing escaped the cardboard flat that the cans were sitting on. The white carpet under the dark brown leaks was untouched. All of the plastic two-litre bottles had lost their pressurization - the CO2 having presumably leaked past the caps in the time since purchase. (She was in various forms of care for about a year before the end, and we held the house off the market for another five months for price-cycle reasons. I don't know how long the soda was there before she went into care.) -- We are geeks. Resistance is voltage over current.
