"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
The Re:Create coalition has just published Unlocking the Gates: America's New Creative Economy, a quantitative report that uses rigorous statistical methods to derive the total income, by state, earned by creators who use the internet to reach their audiences.
Science fiction author Hugh Spencer (previously) has published an essay on how Rod Serling's activist views on human rights were embodied in The Twilight Zone, drawing on the practice of using fantastic fiction to evade social constraints, in the tradition of Gulliver's Travels (to say nothing of books like Pinocchio and Inferno).
Computers that are isolated from the internet and local networks are said to be "airgapped," and it's considered a best practice for securing extremely sensitive systems.
More often than not, you won’t see an accident coming, which means it pays to be proactive and ensure you have the right tools on-hand before you need them. Whether you find yourself in the middle of a power outage or having car trouble at night, you can make sure you’re still capable of navigating […]
Trains may not be the most popular means of conveyance nowadays, but chances are you grew up playing with toy trains or building a model set to wrap around the Christmas tree. In either case, it’s safe to say that locomotives have long carried a unique sense of awe and scale, especially when they’re hundreds […]
When it comes to redesigning or renovating a living space, envisioning changes before they occur can be tricky for most. Thankfully, the web is home to tools that can remove some of the guesswork, like Live Home 3D Pro for Mac. This app lets you create detailed and furnished floor plans for everything from sheds and […]
