"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
Film theorist Laura Mulvey coined the term "male gaze" to describe the "masculine, heterosexual perspective that presents and represents women as sexual objects for the pleasure of the male viewer": in a paper for the Harvard Journal of Law and Gender, Southwestern Law School professor John Tehranian applies Mulvey's idea to the complex and often […]
Science fiction writer/lawyer Casey Fiesler is a maven in the field of tech ethics education (she maintains the amazing spreadsheet of tech-ethics syllabi); she uses science fiction stories as a jumping-off point for her own classroom discussions of ethics in technology.
Illumipaper is a well-developed prototype from Interactive Media Lab Dresden; the researchers behind it used a variety of techniques to create regular-seeming paper with all the traditional characteristics (it can be crumpled, folded, written on with pen and ink, etc); but a wireless controller allows it to be selectively illuminated to provide interactivity (e.g. to […]
The key to learning any new language is feedback. When you’re immersed in conversation, it’s easy to pick up key phrases and pronunciation, but not all of us have the means to jet off to Spain, France or wherever we can learn to speak like a local. The next best thing: The Mondly app. Mondly […]
