If I hear, I forget; if I see, I remember; if I make, I understand. Words by Bruno Munari (1907 – 1998), notable italian designer and artist.

And just think what Munari could have done with 3D printing. In fact, this one is among the most growing trends and sectors in technology. The possible applications are in many fields: science, medicine, architecture, art, defense and aeronautical industries (explaining video above).

The so-called new manufacturing is made of this: a mix by technology, creativity and manufacturing. And this is an opportunity for makers: now, there is the possibility to create real objects by the use of 3D printers, at office or at home.

During this year, there has been euphoria about 3D printing in the business world and at Wall Street.

In this sector, the current major players are 3D Systems and Stratasys. And there is also Autodesk, specialized in the “software side” of the 3D printing. But maybe not everyone knows that also Amazon entered this business, through the stake in Makerbot, a New York-based startup which makes the Makerbot Replicator 2, at home 3D printer.

The industry is on the move: a few days ago, it was announced the exclusive agreement between 3D Systems and Singularity University (Usa), to provide 3D content-to-print solutions and education. The Singularity University is a research center located at the NASA Research Park in Mountain View (California), with a focus on the impact and opportunities presented by advanced technologies.

It is clear that 3D printing will not replace the traditional manufacturing. But, beyond the euphoria, the sector has an interesting perspective.
