"Stress Relief: Improving Structural Strength of 3-D Printable Objects," a paper presented at SIGGRAPH 2012 from Purdue University's Bedrich Benes demonstrated an automated system for predicting when 3D models would produce structural weaknesses if they were fed to 3D printers, and to automatically modify the models to make them more hardy.
Findings were detailed in a paper presented during the SIGGRAPH 2012 conference in August. Former Purdue doctoral student Ondrej Stava created the software application, which automatically strengthens objects either by increasing the thickness of key structural elements or by adding struts. The tool also uses a third option, reducing the stress on structural elements by hollowing out overweight elements.
"We not only make the objects structurally better, but we also make them much more inexpensive," Mech said. "We have demonstrated a weight and cost savings of 80 percent."
The new tool automatically identifies "grip positions" where a person is likely to grasp the object. A "lightweight structural analysis solver" analyzes the object using a mesh-based simulation. It requires less computing power than traditional finite-element modeling tools, which are used in high-precision work such as designing jet engine turbine blades.
New Tool Gives Structural Strength to 3-D Printed Works
NYU PhD candidate Kevin Munger made a set of four male-seeming twitterbots that attempted to “socially sanction” white Twitter users who habitually used racial epithets (he reasons that these two characteristics are a good proxy for harassment): the bots could be white or black (that is, have names that have been experimentally shown to be […]
Michèle B. Nuijten and co’s statcheck program re-examines the datasets in peer-reviewed science and flags anomalies that are associated with fakery, from duplication of data to internal inconsistencies.
In 2002, a peer-reviewed article in the Journal of Personality and Social Psychology claimed that men named “Dennis” were more likely to become dentists; people named “George” or “Georgina” were apt to become geologists; and people with surnames like “Diamond” and “Ricci” were more likely to become bankers.
Loot Crate is a totally different kind of subscription service that mails subscribers monthly boxes filled with curated geek, pop culture, and gamer paraphernalia. Its cult following awaits a box every month filled with everything from bobble heads to T-shirts to special edition collectibles. But nothing gets Loot Crate fans as excited as the limited […]
The ARMOR-X Mini Flexible Phone Tripod is a smartphone tripod that is designed with flexible legs to rest on virtually any type of surface. Other tripods have proved useless unless I conveniently have a flat surface in front of me, which is why this particular tripod was appealing enough to try out. The ARMOR-X is compact and easy […]
You don’t need to get an advanced degree and take out massive loans to become a coder. This bundle of 10 courses was designed to teach anyone to code at home for less than it costs to go out for dinner. I was particularly impressed with this new 2017 bundle because it includes courses on […]
