The Explosive Growth of 3D Printing

MojoKid writes "If you've ever attended a World Maker Faire, the first thing that strikes you is how organic the whole scene is. Inventors, creators, and engineers from all walks of life have their gadgets, science projects, and creations on display for all to see. Some of the creations you see on display range from downright amazing to completely bizarre. One of the big attractions, a technology area that has experienced explosive growth, is the land of 3D Printing. MakerBot took the open source RepRap 3D replicator project mainstream back in 2009 with the release of the Cup Cake CNC machine, then came the Thing-o-Matic and then a little bot called Replicator. With each iteration, improvements in process and technology are bringing better, more capable 3D printers to market, from MakerBot's new Replicator 2, to new players in the field like Solidoodle, Up!3D, Ultimaker, and Tinkerines. To watch a 3D printer in action is like witnessing art, science and engineering all working together in glorious unison."

Eventually we'll probably have Star Trek-like molecular replicators. It means someone is going to "own" the shapes you might print on your 3D printer.

      Eventually there will be a huge cost drop as we transition from manufacturing a part via a custom manufacturing process to just creating it with generic 3D printing equipment. Much like switching from movable type and typewriters to dot-matrix, ink, and laser printers reduced cost, while dramatically increasing flexibility in what you could print (different fonts and even graphics). If we're not careful, or approach copyright as if it's only about intangibles like music or software, we're going to be setting ourselves up for a century where this huge drop in the cost to manufacture could have been used to greatly improve mankind (e.g. people in 3rd world countries printing their own hammers, saws, and nails; replacement gears for motors, etc). But instead most of the benefit of that cost drop is going to end up lining the pockets of copyright holders because of our ridiculous life + 70 years copyright terms.

Go ahead and print a barrel and chamber, see how it does. Just be warned: It has to withstand about 63,000 PSI so good luck there. You try it, I'd make sure ti fire it remotely if you value your hands.

      Keys? So what? That is easy to do. We can make keys out of plastic, but we don't because they wear out too fast. That you can make a handcuff master key is not surprising: They ALL open on one key. This is by design. They are not meant to be perminant restraints, just temporary. The ability to open them is more important than maximum security.

      You have to understand I work in a building with labratory crade 3D printers. They are really cool. The objet spit out a little plastic wrech as a test, you can even adjust it and everything. However it is not going to replace our actual adjustable wrench on account of it not being nearly as strong as the steel one.

      Also, as I said, they can't do anything that is electronic, at all. Have a look at your devices, I bet most of them have an electronic component to them.

    My company makes figurines and toys (primarily) for gaming companies.

    With the advent of 3D printing, we can get the 3D resources from the client, print out the model in 3D within a day, with accurate dimensions, colours and precision, make changes, before we send it off to our factories to produce the molds for production.

    Previously, each mold would cost around $5k to make, with each change costing hundreds of dollars - significant changes resulting in another $5k to restart the mold.

    Cost savings aside, we also save about 6 months development time. The clients love it, because they can see a physical version of their model / figurine instantly; we love it because we can work easily with the client to make changes, and the factories love it because they have a final product and order without months of delays.

    It might not help you, but it sure helps us.

    Same poster, second point.

    There is at least one 3D printing company that I know of that offers 'printing' in brass, bronze and titanium.

    They're using a very old and well known technique, the lost wax - but the wax is printed with the 3D printer, and then the metal poured into the mold.

    This is not only an amazing evolution on an existing technology, but because the final products aren't built up layer by layer, they're structually equivalent to anything coming out of a foundry.

    The ability to print custom tools, gears and moving parts in titanium is incredible.

    Remember the Altair 8800. http://en.wikipedia.org/wiki/Altair_8800

    The Altair was a pretty primitive and useless computer by today's standards but it was really the first personal computer. Looking at it, you wouldn't have predicted all the ways personal computers have changed our lives.

    The 3d printers we have now are primitive and fairly useless. Almost nobody 'needs' one. What about thirty years from now? I'm guessing than many people's lives will be transformed. Many tradespeople will see their industries upended. Old style sign painters had to face competition from unskilled bozos with personal computers and a vinyl cutters. Skills that took a lifetime to learn no longer provided a competitive advantage. The 3d printing revolution promises to be similarly wrenching.

  18. The low-end machines still suck by Animats · · Score: 3, Informative

    I have yet to see a low-end 3D printer that works consistently. TechShop has an "Up" and several RepRaps, but it seems to take several tries to make anything, and nobody gets consistently good parts. The machines that work by laying down a strand of ABS from a heated nozzle (which is all the low-end machines) have trouble getting a consistent bond to the previous layer. The temperature at the bonding point is too critical and not well enough controlled.

    Somebody should try using some high power laser diodes to heat up the point where the ABS strands are fused. Those aren't expensive up to 2 watts or so. You only need a few watts, focused very tightly on the weld area. Welding is about applying heat to both sides of the joint in the weld area. The heated nozzle approach applies the heat on only one side, the new string approaching the weld. The material being joined to is cold. Of course the bond quality is poor.

    The UV-bonded powder machines work fine, but cost about $50K. Laser sintering machines seem to produce good results. The E-beam deposition approach reportedly works very well, but is even more expensive. But ABS through a heated nozzle, not so much.

  19. I am getting so tired of this... by Anonymous Coward · · Score: 2, Interesting

    I know of a machine shop at a university which has several 3D printers -- why would you ever need a mill?

    These are commercial Stratasys units, over $60k each -- and yet their output is inaccurate (-maybe- good to 20 thou) and incredibly brittle and weak.

    People have ALWAYS been able to make things. This lowers the barrier of knowing how -- but the only people that have interesting things to make are those that know how to make them anyways.

    I have found the self-congratulatory nature of the whole Maker movement, because it is entirely hype-driven, around a bunch of inane projects that yes -- while they increase interest in electronics -- take a computer-science perspective on something far, far older. There are so many things done with an Arduino that only would need a dollar of parts, and it just makes me sad -- but sadder still that OH MY GOD THIS IS THE GREATEST THING EVER!

    Maybe I'm just an ornery EE...

    There are many reasons why I print my own pictures, cost being one factor, but artistic control of the process (especially in the use of "special" paper which a commercial printer could not use cost effectively) is more important. I use a Brother DCP 6690 CW printer fitted with a continuous ink supply system (think long range tanks) and I buy ink by the litre. The main cost for me is paper, and hand made 200gsm A3 paper is very expensive. For most work I use water colour paper and that runs to about £5 for 12 sheets of 10" by 14" depending on finish.
    Now translating this to 3D printing, I can see the use for "craftsman standard" devices in the production of intaglio or relief decoration and items such as masks, plaques etc., especially if I can apply true colour (24 bit) to the surface. I don't believe that current devices are capable of producing such items to the required standard of finish, but hope that they soon will.
    I think that we need to stop thinking about duplicating existing objects and see the technology as a means of producing novel products or novel forms designed to take advantage of the characteristics of the device, and especially to the production of "one off" or very limited "editions". How about a specially designed dinner service for that crucial business lunch?
