Alex printed the final prototype. It held. He aced his thesis defense. When the professor asked how he identified such a subtle defect, Alex smiled.
Here is a detailed comparison of the free deform 3D software: deform 3d software free download
In the university lab, every time he 3D printed a prototype and tested it, it fractured near the neck. He knew he needed simulation software—not just the basic stress analysis tools that came with his CAD package, but the heavy artillery. He needed to simulate how the metal would deform , how the grains of the titanium would shift under pressure. He needed . Alex printed the final prototype
