    Finally 3D printing under way on the third print in the Arts of Japan series. The first impression is nothing to write home about – but it of course provides an important base on which the subsequent work will build,

    “2012 may be the year of 3D printing, … “. Really? :))
    If these machines become more affordable, I want one at home. Seeing my models become the real objects is just amazing! :)

    This is an amazing and cutting-edge technology. This kind of 3D printing is something which innovate out-of-the-box from what normally printing is capable of doing! I would definitely share this in my website which focus mostly on creative thinking and works.

    In this video, Lisa gives the audience a useful introduction into the world of additive manufacturing, what we like to more commonly call 3D Printing. She does a great job showing the audience what a fascinating way it is to make things — and she includes examples of intricate objects once impossible to create.

      This isn’t the first 3D printing talk at given at TED, but it’s a good one and the latest one published on their site. It was given at what they call TEDSalon in London in the spring of last year by Lisa Harouni, co-founder of Digital Forming. This is a company that works on the software side of 3D printing — the design tools needed to run the new generaion of 3D printing processes. She has a background in economics, and worked in the G7 Economics team at Deutsche Bank AG before moving over to the consumer products business.

    The ironic thing is that we could have been at this stage 20 years ago were it not for the thicket of patents surrounding the technology, which have now expired. Not that I have a problem with patents, but in this case, they effectively prevented 3D printing from becoming commonplace.

    3D printing may be all the rage these days but the technology is so general that it can be hard to find

  • Biltmore Wedding commented on Jan 30 2012

    Wo! This looks incredibly cool. This will surely change the way we interact with print media.

    This is really amazing technology. From someone like me that was born before the Atomic Bomb, TV, and even ball point pens, to hear something like this is just fantastic. Of course I remember the adults in the family gatherings laughing at the thought of haveing people on the moon. Well that is a fact now isn’t it? So yes this technology is here to stay and it will paly an important part in the future of the world.

    3D printing is a phrase used to describe the process of creating three dimensional objects from digital file using a materials printer, in a manner similar to printing .
