Build a Laser 3D Printer – Stereolithography at Home. RobHopeless writes -  [via]

Here is how to make a Stereolithography 3D Printer. It is still a bit of a work in progress but so far it is working pretty well. This is mainly an experiment which started as a Delta Robot Stereolithography Printer but ended as a more traditional Cartesian Stereolithography Printer.

OpenSCAD – The Programmers Solid 3D CAD Modeller – [via]

OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and Mac OS X.

Unlike most free software for creating 3D models (such as the famous application Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.

OpenSCAD is not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file (see examples below). This gives you (the designer) full control over the modelling process and enables you to easily change any step in the modelling process or make designes that are defined by configurable parameters.

OpenSCAD provides two main modelling techniques: First there is constructive solid geometry (aka CSG) and second there is extrusion of 2D outlines. As data exchange format format for this 2D outlines Autocad DXF files are used. In addition to 2D paths for extrusion it is also possible to read design parametes from DXF files. Besides DXF files OpenSCAD can read and create 3D models in the STL and OFF file formats.

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.
