3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material.[1] 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.

Since 2003 there has been large growth in the sale of 3D printers. Additionally, the cost of 3D printers has declined.[2] The technology also finds use in the jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, GIS, civil engineers, etc.

A large number of competing technologies are available to do 3D printing. Their main differences are found in the way layers are built to create parts. Some methods use melting or softening material to produce the layers, e.g. selective laser sintering (SLS) and fused deposition modeling (FDM), while others lay liquid materials that are cured with different technologies. In the case of lamination systems, thin layers are cut to shape and joined together.




Streamline Your Designing: Dimension 3D Printers are priced for office use, so you can create onsite perfect working models directly from your CAD, made of tough ABS plastic that can be sanded, milled, even painted. And that’s just the beginning:






Israel getting ready to deploy TERMINATORS- Robot Warriors on the battlefield

When the Israeli Defence forces clash in the not-too-distant future, remotely-operated robotic weapons will fight the enemy on land, in the air and at sea, without a human soldier anywhere on the battlefield.

Robots may one day be more effective than human soldiers on the battlefield and they may have a sense of ethics — even a sense of guilt, says a robotics expert who has done a study with the support of the Army’s research office. Here’s what the future of robots may hold: Human soldiers eventually may not be up to speed compared to “humane-oids” in the battle space. Ethical robots that can use lethal force on the battlefield would adhere to international law and rules of engagement

The first robotic systems are already being used by the Israel Defense Forces and other armies across the world, and only budgetary constraints seem to be keeping science fiction from becoming reality.

In places where there is no choice but to send in troops, constantly improving broadband technologies, developed from the civilian communications industry, will serve as an essential part of the infrastructure for all modern military forces.

A helicopter that spots suspicious movement on the ground will, for instance, be able to relay a command to a drone aircraft to photograph the site and transmit the picture in real time to troops on the ground and to the command posts in the rear.

Soldiers will be able to mark their target by its coordinates and with lasers, allowing missiles launched from dozens of kilometers away to be guided by global positioning systems, ensuring accuracy and destruction of the target.

The systems will be coded to prevent enemy interception of the operation. Spy satellites that today weigh several tons will be shrunk down to anything between one and 100 kilograms or less, with engines the size of postage stamps. Infantry rifles will be computerized and fire “smart” rounds telling them when and where to explode. New rockets will also be able to think by themselves to enhance their accuracy.

Israel’s military industries, already world leaders in arms technology, are hard at work developing weaponry for the 2020s. Development of new weapons for the IDF is generally carried out with assistance and in cooordination with the Defense Ministry?s research and development arm.

“The Protector, which we are already marketing, is a vessel that sails all over in all kinds of places without a living soul on board,” says Roni Postman, vice president for R&D at Rafael Advanced Defense Systems. “It can get close up to a terrorists’ boat, address it through a loudspeaker, and open fire at it. In the past, a thing like this required a boat with seven or eight crewmen who were in constant danger. This type of remote control is one of the clearest characteristics of the future battlefield. It will be a battlefield devoid of troops, with vehicles doing what soldiers have done until now.”

Unmanned boats, land vehicles and aircraft will be either controlled remotely or will function autonomously, pre-programmed to carry out a mission from start to finish, such as reaching an enemy bunker, transmitting a photograph back to a command post, launching a projectile at it, and returning, or blowing itself up to destroy the target and the people inside it.

Israel Aerospace Industries, for example, has developed the Mosquito, a UAV with a 40-centimeter wingspan and a silent engine, that can be launched from the shoulder of a single soldier. Even this device may be shrunken down, if the military so requires.
