Rs 500, 10 minutes, and you have access to billion Aadhaar (Indian social security) details

It took just Rs 500, paid through Paytm, and 10 minutes in which an “agent” of the group running the racket created a “gateway” for this correspondent and gave a login ID and password. Lo and behold, you could enter any Aadhaar number in the portal, and instantly get all particulars that an individual may Read more about Rs 500, 10 minutes, and you have access to billion Aadhaar (Indian social security) details[…]

Laser-assisted direct ink writing of planar and 3D metal architectures

The ability to pattern planar and freestanding 3D metallic architectures at the microscale would enable myriad applications, including flexible electronics, displays, sensors, and electrically small antennas. A 3D printing method is introduced that combines direct ink writing with a focused laser that locally anneals printed metallic features “on-the-fly.” To optimize the nozzle-to-laser separation distance, the Read more about Laser-assisted direct ink writing of planar and 3D metal architectures[…]

3D printed items can be reversed engineered using a smartphone to listen to the sound of the printing proces

The team, led by Mohammad Al Faruque, director of UCI’s Advanced Integrated Cyber-Physical Systems Lab, showed that a device as ordinary and ubiquitous as a smartphone can be placed next to a machine and capture acoustic signals that carry information about the precise movements of the printer’s nozzle. The recording can then be used to Read more about 3D printed items can be reversed engineered using a smartphone to listen to the sound of the printing proces[…]

A new way to print 3-D metals and alloys using rust

A team of Northwestern University engineers has created a new way to print three-dimensional metallic objects using rust and metal powders. While current methods rely on vast metal powder beds and expensive lasers or electron beams, Northwestern’s new technique uses liquid inks and common furnaces, resulting in a cheaper, faster, and more uniform process. The Read more about A new way to print 3-D metals and alloys using rust[…]

3D printing polymer-derived ceramics now possible

Because ceramics cannot be cast or machined easily, three-dimensional (3D) printing enables a big leap in geometrical flexibility. We report preceramic monomers that are cured with ultraviolet light in a stereolithography 3D printer or through a patterned mask, forming 3D polymer structures that can have complex shape and cellular architecture. These polymer structures can be Read more about 3D printing polymer-derived ceramics now possible[…]

Chinese Company Constructs the World’s Tallest 3D Printed Building

Chinese company WinSun Decoration Design Engineering Co has expanded the capabilities of 3D printing. After constructing ten houses in under twenty-four hours last year, now they are back with both the world’s tallest 3D printed building – a five-story apartment block – and a 1,100 square meter mansion with internal and external decoration to boot. Read more about Chinese Company Constructs the World’s Tallest 3D Printed Building[…]

Chinese company assembles 3D-printed villa in less than 3 hours

A pioneering 3D-printed house just popped up in Xian, China – and Chinese company ZhuoDa “built” the two-story villa in less than three hours. Made up of six 3D-printed modules, the house was assembled like LEGO bricks before a live audience who were then invited to explore the interior. The modular fireproof home can withstand Read more about Chinese company assembles 3D-printed villa in less than 3 hours[…]

South Korean 3d printer prints thinner than red blood cell

a team of researchers at UNIST has announced that they have developed a high-resolution 3D printing technology that is capable of printing electronic circuits on plastic, metallic or magnetic nanoparticles that are curved and much flexible. According to the team, led by Prof. Jang-Ung Park (School of Materials Science and Engineering), they have succeeded in Read more about South Korean 3d printer prints thinner than red blood cell[…]

Carbon3D Unveils Breakthrough CLIP 3D Printing Technology, 25-100X Faster

The Continuous Liquid Interface Productiongo technology (CLIP) process relies on a special transparent and permeable window which allows both light and oxygen to get through. Think of it as a large contact lens. The machine then is able to control the exact amount of oxygen and when that oxygen is permitted into the resin pool.

Open-Source Syringe Pump Library

A syringe pump was designed using freely available open-source computer aided design (CAD) software and manufactured using an open-source RepRap 3-D printer and readily available parts. The design, bill of materials and assembly instructions are globally available to anyone wishing to use them. Details are provided covering the use of the CAD software and the Read more about Open-Source Syringe Pump Library[…]

3D print your own Smartphone Microscope for $1,-

Using inexpensive glass beads traditionally used for reflective pavement markings at airports, the PNNL team has demonstrated 1000x magnification, which is necessary to see tiny anthrax spores and plague cells. They have also made a 350x version, which is adequate to identify parasites in blood samples or protozoa in drinking water. A 100x version enables Read more about 3D print your own Smartphone Microscope for $1,-[…]
