Gallery: Stratasys' new full-color, multi-material 3D printer announced at SolidWorks World 2
Last night, 3D-printer maker Stratasys Ltd., Eden Prairie, Minn., released the Objet500 Connex3 3D printer — the first and only printer available that can print in color and make composite parts out of multiple materials. Here we show you some of what the Connex3 can do.
Technology forecast 2014: Robots priced for the masses 2
Non-industrial robots are getting better at executing modest to moderately complicated tasks and their numbers are on the rise thanks to new design approaches, open-source controls and hardware, forgiving actuators, and 3D-printed linkages.
Scenes from Autodesk University 2013
Autodesk University 2013 shapes up to be an educational and inspirational event.
Just in: Autodesk computer-aided manufacturing (CAM) on the cloud 2
Today at Autodesk University in Las Vegas, Autodesk Inc. announced that they're now offering a product called CAM 360, cloud-based computer-aided manufacturing (CAM) software.
Quick primer on pulse-ranging technology (PRT) sensors 2
During operation, a PRT sensor emits bursts of light that reach the object, bounce off, and come back to the sensor’s receiver. Here we outline common applications.
Tags from 3D-printed molds swim with sharks
New animal-tracking tags are cast from 3D-printed molds to better conform to animals’ bodies. 3D printing makes the complex organic shapes no costlier to build than plain geometric parts.
HMIs make packagers more flexible
One food-industry manufacturer and contract packager — Crest Foods — is integrating human-machine interfaces (HMIs) and unifying HMI software into their packaging machines to make them more modern and flexible.
The rise of soft robots and the actuators that drive them
Now, yielding robots — those that shift from their equilibrium position when a disturbance force is applied — are promising to bring robotics costs down.
Electric bike balances pedal and motor torque 4

A pedal-electric (pedelec) bike uses a special sensor to synchronize power from an electric motor with that of human pedaling for a smooth, power-assisted ride.

Open hostility to green technologies: A social-science solution 43
Most engineers would probably say that cold hard facts are enough to settle even the thorniest debates about a technology’s merits. Well, they’re wrong. Amateur skeptics hold a vast array of innovations in contempt. Here we take a look at why.
Case study: Dampers protect dams from vibrations

Special shock absorbers on hydroelectric turbine shafts are helping to prevent the catastrophic failure of a dam in southeast Asia.

Three new pieces of design software for 2014: Product spotlight (in pictures)
New software releases in 2014 include comprehensive reverse engineering, inspection, design, and 3D modeling software to reinvents the engineer’s desktop.
Software lets spacecraft carry heavier loads

Researchers at NASA's Ames Research Center are developing a Common Bus spacecraft made of stackable octagonal rings and off-the-shelf parts to form small landers, orbiters, or rovers. CAD software optimizes each section before it's built.
