Software improves structural strength of 3D printed objects. #3DPrinting

The platform relies on a lightweight structure analysis solver and 3D medial axis approximations to automatically detect structural problems. After areas with high structural stress are found, models are corrected by combining three approaches: hollowing, thickening, and strut insertion. This detection and correction repeats until all problematic cases are corrected. The process is designed to create a model that is visually similar to the original model, while possessing greater structural integrity. "We not only make the objects structurally better, but we also make them much more inexpensive," said Radomir Mech, a senior research manager from Adobe's Advanced Technology Labs. "We have demonstrated weight and cost savings of 80%." The new tool is designed to automatically identify 'grip positions' where a person is likely to grasp the object. The lightweight structural a...
