3D Print Metals For Under $2,000
Engineering Materials 1/21/2014 31 comments You can build a low-cost open-source 3D printer that makes metal parts for less than $2,000, designed by Joshua M. Pearce and his team at Michigan Technological University (MTU). MTU and Sigma Labs have signed a memorandum of understanding to support commercial development.
Altair Speeds Smartphone Drop Testing
Blog 1/20/2014 23 comments Altair has reduced drop-testing time in smartphones significantly with the use of computer-aided engineering (CAE). The company worked with LG Engineering to create a simulation model that puts a smartphone through its toughest test -- dropping it on a hard surface.
Slideshow: NASA's Ball Bots Explore Titan
Blog 1/10/2014 23 comments The latest NASA exploration robots are the Super Ball Bots, and they sort-of look like spheres, but are constructed quite differently from rigid models. These tensegrity-based bots are being designed to go to Titan.
Slideshow: 3D Systems Changes What Engineers Can Do With 3D Printing
Engineering Materials 1/9/2014 15 comments 3D Systems has introduced printers, services, and software that will change what engineers can do with 3D printing. These include a bigger and faster SLA build volume, another printer that does multiple colors in plastic, one that prints plastic multi-material objects bigger and faster, ceramic 3D printing via the cloud, and a universal print driver.
Slideshow: 3D Printing Metals in Space
Engineering Materials 1/7/2014 24 comments The European Space Agency (ESA) has begun a program for designing a large-scale 3D printer that will work in space to make high-performance metal components and even entire satellites.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
