Engineers can now reverse-engineer 3D models

A system that uses a technique called constructive solid geometry (CSG) is allowing MIT researchers to deconstruct objects and turn them into 3D models, thereby allowing them to reverse-engineer complex things. The system appeared in a paper entitled “InverseCSG: Automatic Conversion of 3D Models to CSG Trees” by Tao Du, Jeevana Priya Inala, Yewen Pu, Andrew Spielberg, Adriana Schulz, Daniela Rus, Armando Solar-Lezama, and Wojciech Matusik. “At a high level, the problem is reverse engineering a triangle mesh into a simple tree. Ideally, if you want to […]

3DHubs, once a community 3D printing service, is now sourcing all 3D prints internally

3D Hubs, like MakeXYZ, was a community-based 3D printing service that let anyone with a printer sell their prints online. Founded in the heyday of the 3D printing revolution, the service let thousands of makers gather a little cash for making and mailing prints on their home 3D printers. Now, however, the company has moved to a model in which its high-end partners will be manufacturing plastic, metal, and injection molded parts for customers willing to pay extra for a professional print. “Indeed, more focus on high […]
