3D Printing: What it is and why it brings a new industrial revolution

A real revolution in industry and in everyday life promises new technologies of prosthetic construction, better known of which is the three-dimensional printing. It was recently translated into Greek and published the first book detailing the developments in this new technological field, while in the United States another landmark book was published by the American pioneers of the new technology.

The book “Prosthetic Construction Technologies: three-dimensional printing, rapid prototyping and direct digital construction” by Ian Gibson, David Rosen and Brent Stucker, which was published internationally in 2015, was published in our country by the critics editions. The editing and translation of the 456 pages were made by Vasilis Dedousis and Yiannis Giannacsis.

The book is one of the most thorough writings in this field, presenting an overview of the basic principles and concepts, as well as an in-depth analysis of individual technologies as well as developing applications such as Micro-scale production, medical applications, the construction of pieces for aerospace applications and the rapid production of finished products and tools (Rapid Manufacturing/Tooling).

The book also provides an overview of assistive technologies, such as related software systems, as well as secondary reproduction methods (in-play, precision casting) and track processing (plating, grinding).

Ian Gibson is professor of industrial design at Deakin University in Australia, David Rosen is a professor at the School of Mechanical Engineering at the University of Technology of Georgia (Georgia Tech) in Atlanta, USA, while Brent Stucker is Co-founder-CEO of 3DSIM LLC and professor of Industrial design at the University of Lyisville, Kentucky.

Designing reality

The new landmark book that has just been released in the US by the pioneers of the new technology brothers Neil, Alan and Joel Gersenfeld, is titled “Designing Reality” (Neil, Alan & Joel Gershenfeld “Designing Reality”, Basic Books, 297 p .). It provides for the widespread expansion of the new three-dimensional manufacturing technologies, which constitute the “locomotive” for a third digital revolution, even more radical than the previous two in the field of computers and communications.

The physicist and computer expert Neil Gersenfeld, director of the Center for Bits and Atoms of MIT University, is the world pioneer of digital constructions on a small and community scale. Two decades ago, the lesson of “How to make (almost) everything” triggered the international movement of Fab Labs, whose central goal is for each neighbourhood, group and company to be transformed into a manufacturer of every Kind of tools and machines, in improvised “home-made workshops” focusing on 3d printers, computers and lasers.

He, in the new book, envisions a future creators ‘ society, where everyone will design digitally and produce what they want on the spot. At a later stage, Neil Gersenfeld predicts that additive manufacturing and digital fabrication technologies will utilize programmable biological materials, enabling products to evolve on their own, but also They are self-fixed.

The other two siblings are somewhat more cautious, expressing concerns about whether the widespread spread, at a community even level, of such construction capacities can do more damage to the environment or intensify Socio-economic inequalities. As they say, the previous technological revolutions have not wiped out the digital gaps and perhaps the next one will not succeed-if it does not make things worse.

They emphasize that the laboratories Fab Labs have actually spread internationally and their number doubles every 18 months internationally, yet very few people have so far acquired the ability to produce the things they want themselves. Given that the 3d printing depends mainly on petrochemical products, petroleum derivatives, Alan and Joel Gersenfeld (innovative businessman the first and professor of the Brandace University the second) are afraid of setting up of such a laboratory in every home is an environmental nightmare.

While they do not rule out that-as with so many other things in the past-big business interests will finally be able to take on this new digital construction revolution, bringing it to their own measures.

The 3D printing industry is evolving and now 3d printing machines are becoming smaller and smaller. Companies are producing 3D pens suitable for little children. Techodom lists one of them in their list with remarkable things to buy that cost less than 100 USD.
