I downloaded the CAD prints of several guns before they were deleted off the internet, so that when I get my hands on a 3-D printer, I can print out guns

A lot of people downloaded those files, and they are still on torrent websites like The Pirate Bay, so I doubt anyone will be able to stop the spread of these. The only problem would be how strong the plastic is, since they can shatter when fired. I'd recommend using a metal printer for those, like they use at NASA, since all metal is stronger than plastic.

Killing people frankly is not a value of liberty.
To all who think guns should be banned, have you ever thought that guns helped many peope liberate themselves?

Mexicans once demonstrated against the corrupt, undemocratic government...unarmed. This is what happened:

I am a pacifist and against sport hunting. But I think civilians should always be able to take down their governments if they feel the need.

Most 3D printers cost more than actual real guns themselves. It would be cheaper to just go purchase a real firearm, many quality 3D printers cost thousands of dollars multiple times more than many firearms. Also the CAD prints are not deleted from the internet they are seeded across the web.

If you can't buy a firearm it's a solution.

What makes you think he can't buy a firearm? AFAIK he lives in Pakistan. You can always buy a firearm if you really wish to. Besides there will be coming legislation against printed guns as well, so it's not a solution.

I know about the issue. A friend and I have been discussing cutting metal with 3-D printers. I am still researching it.

One could start a business based on 3-D printers. Print whatever people wish for...guns, toys, memorabilia etc.

Ultimaker 2 3D printer pushes the limits of speed and accuracy

[IMG]http://t2.************/images?q=tbn:ANd9GcRRTRLx4v2mfBtGUArrYKOYxfvXywnJARyzjgjZ0Tdm4jDyikya[/IMG]

Ultimaker, which was born in 2011 as an outgrowth of the RepRap project, and which quickly grew to become an important player in the home consumer 3D printing market, has announced its second generation 3D printer. Boasting improved reliability, user-friendliness, and an increased print volume.



"We are an independent company, we don't have outside investors," explained Erik de Bruijn, Ultimaker co-founder, at the Ultimaker 2's public unveiling. "I think if we can all start to see the world not as a fixed thing, but as an environment that we can actually shape together [...], building on top of each other's work, then it would be a very big irony if the devices that we used to do that [...] would be a closed environment. So that's why I'm very pleased to announce that the Ultimaker 2 will be completely open source."

The statement underlines one of the key differences between Ultimaker and Makerbot, which drifted away from the open source model with its Replicator 2 printer, and was acquired by 3D printing giant Stratasys in a $403 million dollar deal earlier this year. It was a move that disappointed some in the maker community, but only time will tell what kind of impact it will have.



"A lot of things have changed. I can count the number of parts that have stayed the same on one hand. Almost everything has been redesigned and improved, and a lot of attention has been paid to the details," Erik says. Besides new parts, the second generation Ultimaker was designed with user-friendliness in mind. The printer's user interface allows you to find and print files directly from the built-in SD card reader (a wireless module is also in the works). And, unlike the Ultimaker Original, the Ultimaker 2 comes fully assembled rather than as a DIY kit.

When it comes to speed and accuracy, the Ultimaker 2 appears to be in a class of its own among the fused-filament fabrication printers. Make magazine called the Ultimaker Original the "most accurate and fastest 3D printer" in November 2012, and the Ultimaker 2 is capable of the same performance with a slightly larger build volume. It can print from 30-300 mm/s at a layer resolution of just 20 microns (0.02 mm) within a 225 x 225 x 205 mm build volume. By comparison, the Makerbot Replicator 2 has a minimum layer resolution of 100 microns (0.1 mm).



Ultimaker's Cura open source software prepares models for printing. It plans, coordinates and auto-slices models, but doesn't appear to generate support structures. It was designed for everyone, allowing novices to print a file with a click of their mouse, but has more in-depth options for more advanced users. And because Cura is open source, it can be modified and enhanced by users as well.

The print head moves using Cartesian coordinates, melting 2.85-mm-diameter PLA or ABS plastic onto a heated build platform. When cool, printed objects easily separate from the printer. "You can almost blow it off gently," de Bruijn explained with a smile. Spools of 0.75 kg PLA cost €31,50 ($42.83), and come in eight colors. You can also purchase spools that are translucent or flexible for €34 ($46). That's about the same as you'd pay for filament on the Makerbot Replicator 2. In the future, Ultimaker plans to release an upgrade that will add a second print head, which will make it a dual material machine.



In line with its open source philosophy, Ultimaker announced a "spin-along" it calls Ultilabs, which is centered around the hacker and maker community. Details were kept under wraps, but complimenting Ultilabs is a site called Youmagine where users will be able to share files and modifications to Ultimaker's software APIs, which could lead to new tools for the community. Youmagine will analyze file uploads so that it can list useful information, such as how much it will cost in grams to print it.

If Youmagine seems a lot like Ultimaker's version of Thingiverse, Makerbot's repository of 3D files, that's no coincidence. It may be late to the party, but Youmagine provides an alternative to Thingiverse, where people can share their work without it falling under the banner of a big corporation if they prefer. Unfortunately the site isn't set up in such a way that users can monetize their files. Like Thingiverse, Youmagine is not designed just for Ultimaker users but for the wider 3D printing community. With Ultimaker's commitment to remaining open source, it could become the preferred home of the thriving maker community.

Ultimaker 2 retails for €1,895 (about US$2750), which is a few hundred dollars more than the Makerbot Replicator 2.

Amaze project aims to take 3D printing 'into metal age'



The European Space Agency has unveiled plans to "take 3D printing into the metal age" by building parts for jets, spacecraft and fusion projects.The Amaze project brings together 28 institutions to develop new metal components which are lighter, stronger and cheaper than conventional parts.
Additive manufacturing (or "3D printing") has already revolutionised the design of plastic products.



Printing metal parts for rockets and planes would cut waste and save money.
We need to clean up our act - the space industry needs to be more green. And this technique will help us” The layered method of assembly also allows intricate designs - geometries which are impossible to achieve with conventional metal casting.

Parts for cars and satellites can be optimised to be lighter and - simultaneously - incredibly robust. Tungsten alloy components that can withstand temperatures of 3,000C were unveiled at Amaze's launch on Tuesday at London's Science Museum. At such extreme temperatures they can survive inside nuclear fusion reactors and on the nozzles of rockets.

"We want to build the best quality metal products ever made. Objects you can't possibly manufacture any other way," said David Jarvis, Esa's head of new materials and energy research."To build a [fusion reactor], like Iter, you somehow have to take the heat of the Sun and put it in a metal box.

"3,000C is as hot as you can imagine for engineering."If we can get 3D metal printing to work, we are well on the way to commercial nuclear fusion." Additive manufacturing with metal is not new; General Electric, for example, has used the technique to make fuel injectors for one of its aircraft engines. China claims to be using 3D printing to manufacture load-bearing components in aircraft.

And in July, Nasa announced that it had successfully tested a 3D-printed rocket engine part. Amaze is a loose acronym for Additive Manufacturing Aiming Towards Zero Waste and Efficient Production of High-Tech Metal Products. The 20m-euro project brings together 28 partners from European industry and academia - including Airbus, Astrium, Norsk Titanium, Cranfield University, EADS, and the Culham Centre for Fusion Energy.

Factory sites are being set up in France, Germany, Italy, Norway and the UK to develop the industrial supply chain. Amaze researchers have already begun printing metal jet engine parts and aeroplane wing sections up to 2m in size.
These high-strength components are typically built from expensive, exotic metals such as titanium, tantalum and vanadium. Using traditional casting techniques often wastes precious source material.

Additive manufacturing - building parts up layer-on-layer from 3D digital data - produces almost "zero waste"."To produce one kilo of metal, you use one kilo of metal - not 20 kilos," says Esa's Franco Ongaro. "We need to clean up our act - the space industry needs to be more green. And this technique will help us."

Printing objects as a single piece - without welding or bolting - can make them both stronger and lighter. A weight reduction of even 1kg for a long range aircraft will save hundred of thousands of dollars over its lifespan. "Our ultimate aim is to print a satellite in a single piece. One chunk of metal, that doesn't need to be welded or bolted," said Jarvis.

"To do that would save 50% of the costs - millions of euros." But Jarvis is candid about the problems and inefficiencies that still need to be overcome - what he calls the "dirty secrets" of 3D printing. "One common problem is porosity - small air bubbles in the product. Rough surface finishing is an issue too," he said.

"We need to understand these defects and eliminate them - if we want to achieve industrial quality. "And we need to make the process repeatable - scale it up. "We can't do all this unless we collaborate between industries - space, fusion, aeronautics. "We need all these teams working together and sharing."

Robot arm gives 3D printer unprecedented freedom



Researchers at the TU Delft Robotics Institute have built a prototype of a unique 3D printer together with researchers from Océ. The printer works by means of a robot arm with various degrees of freedom and utilises a high-performance printer head from Océ. The robot arm is able to print in all directions, which means that the arm can move the printer head along complex, curved surfaces, giving it a number of advantages compared with current 3D printers (in which the printer head is only able to move along straight lines). This means that the new way of printing will not only have shorter printing times, but the print quality will also be higher. And it will also be possible to print on existing objects, with all kinds of potential applications, such as repairing tears, coating and restoration.
