  •  Not within our lifetime. (5+ / 0-)

    3d printing is EXPENSIVE not cheap. For whatever level of quality mass production via factory is always going to be cheaper within our lifetime.

    Eventually we may have some paradigm shift in manufacturing but that will not happen within a reasonable time frame.

    Once 3d printing becomes competitive with any form of manufacturing that will be a COMPLETE change in our economy.

    You think outsourcing to China and Bangladesh is bad? Try having no need for humans doing any manufacturing ANYWHERE in the world.

      the printers and plastic.  So there's that. /wishing that thought didn't occur to me.

      for a living that can be done this way, that is complicated or rare enough that the cost of 3-d was relatively less important.

      I'm going to be losing a lot of sleep for a while.

      keeps getting cheaper all the time.

      Already you can buy basic-level 3d printers for less than $400--and if you're willing to assemble it yourself you can download plans for free and print out all the parts for just the cost of metal and plastic printing materials.

      Once 3d printing becomes competitive with any form of manufacturing that will be a COMPLETE change in our economy.
      Absolutely. It will be a game-changers just like the Computer Revolution. It's just a matter of time until 3d printers are as cheap and ubiquitous as inkjet printers are now. Each of us will own our own means of production.

      raw materials, move the finished products, install stuff in peoples homes, convince people to buy it, design it, ect.

      There will still be plenty of work to be done, and the fight will remain what it has always been.

      For customization or low volumes, can be relatively cheap.

      Otherwise, I agree with your general observation except in mass-production applications where small amounts of materials or large areas in a single pass are concerned.

      Some mass-produced "large electronics" are already manufactured with printable processes integrated with conventional processes.

      For example, some large panel displays now use lighting circuitry printed on the display substrate replacing large circuit boards which would be thicker, more expensive and more complex to assemble. What you do is print a silver ink circuit pattern, a dielectric coating and then silver paste dots and mount the components, then solder using a low temperature sintering process. Total cycle time is shorter and less materials are used. The precision (one set-up, two or three workstations) enables building small structures on a large area and the capital investment is also lower.

      Also some very small structures are built quickly.

      But, folks, this does not mean you are going to build your own TV with a maker bot unless you can afford about $5Bn for your own large panel LCD plant.
