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.

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. With OpenFab's streaming architecture, data about the design of the 3D object is computed on demand and sent to the printer as it becomes available, with little start-up delay.

(Click to enlarge.) “It’s difficult to create structures out of liquids, because liquids want to bead up. The researchers developed multiple techniques for creating these structures, which can be used to connect electronic components in three dimensions. One technique involves stacking droplets of liquid metal on top of each other, much like a stack of oranges at the supermarket. Another technique injects liquid metal into a polymer template, so that the metal takes on a specific shape.

Dickey’s team is currently exploring how to further develop these techniques, as well as how to use them in various electronics applications and in conjunction with established 3-D printing technologies. 10 Reasons Why Multi-Material 3D Printing is Better for your Product Design & Development. 10 Reasons Why Multi-Material 3D Printing is Better for your Product Design and Development The newest generation of 3D Printers is expediting product development and design.

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. Researchers are interesting in this field primarily because building robots is a time consuming and expensive enterprise.

Graphene: 3D Printing Using This Amazing Material | 3D Print HQ. 3D printing has had enormous benefits both in Prototyping and Object Fabrication. 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. However, the quick transformation of 3D printing from a mere prototyping technology to a method that can be used in the creation of final objects surfaced a number of issues. The biggest issue with 3D printing is the need to have a more reliable printing material. One that could be used to print high quality final objects and products that one could sell to the public. So is Graphene the solution that we have been waiting for? What’s So Unique about Graphene? Advanced Possible Applications. 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”. A quick look around the section gave me the impression that Amazon is still catering to the Maker segment of the 3D Printing community. Among the products available are the MakerBot Replicator2, the LulzBot AO-101, the Airwolf3D and a number of other models. In addition to printers Amazon is offering a vast selection of both ABS and PLA filament, inspection and repair tools as well as enough parts to design and build your own 3D printer.

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.

One other notable benefit of Dalian’ new printer is its use of industrial grade sand as its print material. Amazon opens doors on 3D printer storefront: Is this a sign of things to come? If a structural change to Amazon.com is any indication, the company is looking to take on the 3D printer scene. According to reporting from 3D printing enthusiast blog Personalize, the online retail giant has recently opened a 3D printer storefront for U.S. consumers. It’s a bit hard to find ordinarily–you have to look for the “Additive Manufacturing Products” subcategory inside the Industrial and Scientific department. Once there, you’ll be presented with a one-stop-shop for all your 3D printing needs, whether you want to plunk down a couple grand on a new printer, or just pick up a book or two on the subject to see if it’s something you want to invest in.

All of this comes at an interesting time in the 3D printing industry. Makerbot Industries, maker of a number of consumer-grade 3D printers, is said to be in acquisition talks. Amazon CEO Jeff Bezos has invested in Makerbot in the past, so some have speculated that this could be a prelude to an Amazon acquisition. What do you think? 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. As inspired by the replicators on Star Trek?? I do hear tell that 3D printers are among the things available on modern air craft carriers to fabricate parts needed for aircraft repairs. There's more than one variety of 3D printer. Print Real Objects With The MakerBot Thing-O-Matic 3D Printer (3 minute video) MakerBot Replicator 2X Now Shipping!
