Opening Statements

3D printing will change us

Lyndsey Gilpin: 3D printing is going to change the world. 3D printing will change us: the way we prepare food, how we replace broken objects, how we exchange gifts, how we play with our children. It will affect our power consumption, our time management, our imagination. It will also radically change every industry we interact with: uutomotive, food, medical, aerospace, manufacturing, and shipping.

3D printing has been around since the 1980s, but its moment in the sun is just beginning. We haven't even scratched the surface of 3D printers' potential in the industrial and consumer worlds. As innovators push the limits of this technology by using open source design platforms, crowdfunding campaigns, energy efficient models and creative materials, the industry will only grow more rapidly. The real questions are whether society is ready for the change -- and if the laws can keep up with it.

Missing a number of core features

Charlie Osborne: 3D printing is no doubt a technology which can benefit a number of industries, including manufacturing and healthcare. The technology has sparked the imagination of people in the consumer space -- the hefty investment of a tiny $299 home 3D printer on Kickstarter recently supporting this -- but in the end, it is missing a number of core features to truly make it "revolutionary."

Not only is additive manufacturing still expensive and generally complicated, but it is missing user-friendly software that will introduce it properly in to the consumer space. While images of 3D printed guns make us think "Wow! I can do that!," it is not going to decentralize manufacturing, create a second manufacturing revolution or make sure we are all touting our own plastic weaponry any time soon.

3D printing is valuable, but not easy. You need training, technological acumen and money behind you to enjoy it at home. We're not going to wake up one day and be able to print off our own clothes and tools quickly and cheaply, and so 3D printing, to be of any use in business, will stay fixed in the manufacturing space rather than truly ever enter the consumer realm.

  • It needs a "killer app."

    It needs a "killer app."

    What can you really use it for that will really put it over the top as something the average consumer will want?

    Right now, it seems to make sense for certain things, such as prototyping and creating one-off products. But I don't see what the mass appeal is yet.

    • There is already a killer app.

      Unfortunately, it is LITERALLY a killer app: untraceable guns. Sure, it takes gunsmithing skill and engineering savvy (to pick the right material and treat it properly after fabricating), but criminal gangs, terrorist groups, and revolutionary armies can get people with those skills for cash. At least for small arms like AK-47 clones, it may soon no longer be necessary for these non-governmental armies (which is what they are) to be clients of any outside government, or to depend upon the commercial (and presumably regulated by their own governments) arms manufacturers to equip their soldiers/thugs.

      • "killer app"? + id10t = potentail Darwin award.

        Anybody that know 3D printing will know not to make a gun with it. Plastic gets soft with heat and reform. Really bad idea for making guns. Good for Darwin awards. Lost wax casting with a 3D print is a better idea, but aluminum is not strong enough for a barrel. So bad idea. Use mild steel? Great- but now a real furnace are required. But you will still need to have a machine shop to build a good gun- clean of the product and to make everything fit.... There are loads of machine shops around - why are there no rants and raves about machine shops? youtube for Afghan lathe.

        • No "APP" can make sustainable materials

          Some multi Md'$ to invest in controlled environment powdermetal enclosures
          4 to make sustainable products.

          Can be used to speed up molds for die casting, but then one need a plant.

          One benefit though, is that one can make true three dimensional models
          that can be viewed in a way where both of our eyes synchronously focus
          on a true perspective planes, and hence,
          enhances our own supercomputer/brains capabilities in a way that rarely occurs
          while viewing emulated 3D on a flat screen.

    • We all know the killer app. Its not here....yet..


      Its one thing to produce a 3D printed object.

      What the killer app is, or would be, the ability to stick something you or your neighbor own in the printer housing, the object gets a 3D laser scan, you pull out the original and then you start grinding out as many replicates as you need or want.

      That's the killer app.

      And I for one find it very hard to believe it will not arrive one day. You can imagine the issues this will bring up!

      Think sending a copied version of a song online to be downloaded by anyone is trouble?

      Wait until you can make a 3D copy of just about anything that can go into a 3D printer and put that data online for anyone to download.


      Chew on that for awhile.

      • It will likely be a long time before we reach Star Trek quality and speed.

        I wouldn't expect anything like Star Trek replicators any time soon - certainly not within the first few generations of 3D printing.

        In your scenario, you mentioned laser scanning. There are two problems with this:

        1) You can't really tell the material used from the 2D scan. You could scan a painted metal object, and the printer will likely print a plastic object.

        2) It can't reach the insides of the object (unless you plan on destroying the original). You'd scan a watch, but the replica won't function like a watch; it would simply be a shell that looks like a watch.

        • Im totally aware of those restrictions...currently.

          And Im not talking Star Trek replicators either.
          What Im simply saying is that its entirely possible to create a rig that could scan a simple object, then print it off.

          Its not hard to foresee in some not too distant future a system that could actually create a 3D x-ray image of a product with the appropriate apps to code it up into a 3D printable object with some fairly sophisticated inside details.

          And remember, Im not saying "stay tuned for next week" here. Depending on a whole lot of things this could take a while. But there is already plenty of 3D scanning around of some fairly sophisticated parts.


          For example.

          When you have a moderate sized device that can scan an object then print off copies, that's going to be a game changer.

          You hear the complaints in the music industry about copying music takes away the incentive to produce music; which I would say arguably changes things but doesn't necessarily take away incentive to sing and play music, how about copying a 3D product? Typically the entire motive for producing a 3D object one would then sell is entirely profit driven. If you make just one and then half the world can produce cheaper copies at home....

          I can see how that could become an issue.

          • Or scan the blueprints...

            And the printer could potentially read the plans and construct the innards...

          • Blueprints - this is the 21st century

            Many parts never exist as a drawing (blueprint) in modern engineering / manufacturing. It's modelled, rendered and the cad file is used the machine the mould tool or cut sheet-metal. Often if a drawing does exist it's to support archaic systems and probably doesn't include all the detail required to manufacture the part - often they just include a few 'inspection' dimensions for validation.

    • a lot more than software

      it will be popular for make your own toy.
      But when the real product is made of steel, glass, titanium, etc.. it's a non starter.
