Tinkercad – Design physical things in your browser – [via]

Have your first 3D project ready for printing in minutes. Tinkercad is a new and faster way of creating designs for your 3D printer. With the help of the latest web technology you can now use a solid modeling CAD directly in your browser.

The user interface is designed to get things done fast and to be quick to learn. With only three basic tools you can create a wide range of useful things. Once your project is ready simply download the STL file and start your 3D print.

Portable, high-res 3D imaging tech

MIT researchers have improved a gel technology that can image microscopic features without expensive equipment, opening up applications in forensics, medicine, and other fields.

Developed by Edward Adelson, Micah Johnson, and colleagues, GelSight acquires surface textures and shapes by pressing a block of clear rubber onto them, revealing striking 3D details. It can even visualize a pulse when pressed on a wrist.

Originally presented in 2009, the technology has been improved to resolve features as small as 2 microns across and is being presented in a paper (PDF) at this week’s Siggraph 2011 computer graphics conference in Vancouver, British Columbia.

When an object is pressed against the clear rubber, its reflective skin on one side distorts to assume the shape of the object. The skin is coated with paint that contains flecks of metal that are smaller than the features they resolve.

Baolab Microsystems has developed innovative, pure CMOS MEMS devices that use Lorentz force sensors to detect the strength and direction of the Earth’s magnetic field. The new 3D Digital NanoCompass™ technology matches existing performance benchmarks for sensitivity, power consumption and package size at dramatically lower cost. An additional unique feature is autocalibration for consistent accuracy.

The new compass chips utilise Baolab’s NanoEMS™ technology, which allows nanoscale MEMS devices to be fabricated using standard high-volume CMOS lines and fully integrated monolithically with analogue and digital electronics. The MEMS elements are defined within the existing metal interconnect layers on the wafer as part of the normal CMOS production process. Conventional 3D compass devices typically use magnetoresistive materials or Hall-effect devices combined with magnetic field concentrators to detect the direction of the Earth’s magnetic field.

RS Components has released PCB Converter for SketchUp, a software tool that converts CAD files in Intermediate Data Format (IDF) to Collada format for use in SketchUp. This enables designers to use SketchUp as a 3D CAD back-end for to PCB design and brings SketchUp into the electronic product design realm. [via]

Earlier today Intel announced that its 22nm process would not use conventional planar transistors but rather be the first time Intel is using 3D Tri-Gate transistors. This is a huge announcement that fuels Intel’s leadership in the mobile/desktop/server CPU space and makes it a lot more attractive in the SoC space, let’s understand why.

Glazed Ceramics is perfect for any application such as a plate, cup or bowl as it is the first 3D printed food safe material available on Shapeways. Shapeways 3D Printed Glazed Ceramics material properties are exactly the same as standard ceramics as it is produced with fine ceramic powder which is bound together with binder, fired, glazed with lead-free, non-toxic gloss finish.

Printers capable of producing three-dimensional objects have been available for years. However, at the Vienna University of Technology, a printing device has now been developed that’s smaller, lighter and cheaper than ordinary 3D printers. With this kind of printer, everyone could produce small, tailor-made 3D objects at home, using building plans from the Internet – and this could save money for expensive custom-built spare parts.
