Rapid Prototyping – Meccanismo Complesso. Introduction The prototypes (from the greek πρωτότυπος ‘Prototipos’ ie ‘first model’) are often intended as partial or approximate models of a system that we want to develop (design phase) and their realization is often a very critical stage in the production process.
But we can consider even physical models made in a single copy (or at least in a small number) as prototypes for purposes other than production, often for purposes of study or analysis. For the realization of a prototype, the classical methodology is in keeping with the classical conception of industrial mechanical production: the processing of the starting material by chip removal (subtractive method). Also the production by forming (applying thermal or mechanical forces to starting material to produce the object by deformation) makes use of molds which in turn are generated for subtractive methodologies.

MIT Develops New Ways to Streamline, Simplify 3D Printing. Jul.24, 2013 State-of-the-art 3D printing hardware is capable of mixing many materials, it is now possible to produce a wide variety of 3D objects.
But while the hardware exists to reproduce complex, multi-material objects, the software behind the printing process is slow and difficult to use. In order to fabricate complex surfaces containing bumps, color gradations and other intricacies, printing software must produce an extremely high-resolution model of the object. Such models often amount to petabytes of data, which current programs have difficulty processing and storing. A team of researchers from the MIT Computer Science and Artificial Intelligence Lab (CSAIL) developed OpenFab, a programmable "pipeline" architecture that allows for the production of complex structures with varying material properties. 3Doodler First 3D Printing Pen. 3Doodler is the world’s first and only 3D printing pen that can draw in the air.
It’s the 3D printing pen you can hold in your hand. 3Doodler is using ABS plastic (the material used by many 3D printers), 3Doodler draws in the air or on surfaces. It’s compact and easy to use, and requires no software or computers. You just plug it into a power socket and can start drawing anything within minutes. Researchers Build 3-D Structures Out of Liquid Metal. Researchers from North Carolina State University have developed three-dimensional (3-D) printing technology and techniques to create free-standing structures made of liquid metal at room temperature.

This innovative technology is revolutionizing the industry by combining various materials within a single printed model. Designers are discovering the advantages of these new systems to, produce concept models that more accurately represent final prototypes. This helps designers streamline their decision-making regarding product materials. In this white paper, you will learn about the different capabilities of multi-material 3D Printers from Objet and how companies are using rapid prototyping during the design and development of manufactured end products. Harvard Robots are 3D Printed, Self-Assembling. Recently at the IEEE International Conference on Robotics and Automation in Germany, Harvard and MIT robotics students unveiled their newest creation, a self-assembling 3D printed “inch worm” robot.
Designed to demonstrate a concept called sequential folding, a self-assembly process, the robots are printed in a completely flat configuration. From this flattened state, the robots are animated with a jolt of electricity thatcauses their flattened bodies to fold into the desired configuration. According to IEET Spectrum, “Self-folding happens thanks to shape memory polymers that contract when heated. By printing these polymers on one side of a hinged substrate and then heating them, the hinge can be made to bend. The amount of bend is controlled by etching flexible connectors that connect both sides of the hinge, and with enough hinges heated in the right order, it's possible to create fairly complex folded shapes, including things like interlocking structural elements.”

With the rapid implementation of the technology, the need for mass production of objects will be sooner or later completely rooted out. People will be obtaining blueprints of objects online, from the comfort of their homes, and printing products instantly whenever one feels like. Not to mention that this will substantially lower the prices of acquiring objects for there will be no shipping or delivery costs involved. Amazon Expands Into Additive Manufacturing. Kyle Maxey posted on June 10, 2013 | Comment | 3371 views While Amazon CEO Jeff Bezos may believe that 3D printing is still a long way from changing the way industry makes and distributes products, his online marketplace isn’t shying away from the opportunity to sell the revolutionary technology.
In a recent addition to its website, Amazon has decided to add a new section to it’s “Industrial & Scientific” market category – “3D Printers & Supplies”. World’s Largest 3D printer built in China. Kyle Maxey posted on June 11, 2013 | Comment | 8171 views Dalian University of Technology has announced the development of the world’s largest 3D printer.
The massive laser sintering 3D printer has a build volume of 1.8m3 and can reduce print processing time by some 35%. In addition, the printer’s “contour scanning” printing technique can also reduce manufacturing costs by 40% when compared to other laser sintering machines. According to Yao Shan, Professor at Dalian University, the key to the time and cost reductions is the fact that the printer only makes an outline of each layer rather than building out an entire solid surface. Amazon opens doors on 3D printer storefront: Is this a sign of things to come? 3D printers and gun control. Time to sprinkle a little variety into this blog.
So today's article looks at the emerging supply of 3D printers and contemplates what they mean in the silly discussions of gun control going on. Not sure if you've been paying attention to the topic of 3D printers. The idea is to have a device that can take a computerized design for an object and actually fabricate that object.
