PATO: Producibility-Aware Topology Optimization using Deep Learning for Metal Additive Manufacturing

no code implementations8 Dec 2021 Naresh S. Iyer, Amir M. Mirzendehdel, Sathyanarayanan Raghavan, Yang Jiao, Erva Ulu, Morad Behandish, Saigopal Nelaturi, Dean M. Robinson

In this paper, we propose PATO-a producibility-aware topology optimization (TO) framework to help efficiently explore the design space of components fabricated using metal additive manufacturing (AM), while ensuring manufacturability with respect to cracking.

Curvy: An Interactive Design Tool for Varying Density Support Structures

no code implementations19 Feb 2021 Erva Ulu, Nurcan Gecer Ulu, Jiahao Li, Walter Hsiao

Combined with the build orientation optimization, Curvy provides a practical solution to the design of support structures with minimal perceptual or functional impact on the target part to be printed.

Structural Design Using Laplacian Shells

no code implementations25 Jun 2019 Erva Ulu, James McCann, Levent Burak Kara

We introduce a method to design lightweight shell objects that are structurally robust under the external forces they may experience during use.

Enhancing the Structural Performance of Additively Manufactured Objects

no code implementations1 Nov 2018 Erva Ulu

The ability to accurately quantify the performance an additively manufactured (AM) product is important for a widespread industry adoption of AM as the design is required to: (1) satisfy geometrical constraints, (2) satisfy structural constraints dictated by its intended function, and (3) be cost effective compared to traditional manufacturing methods.

Efficient Load Sampling for Worst-Case Structural Analysis Under Force Location Uncertainty

no code implementations25 Oct 2018 Yining Wang, Erva Ulu, Aarti Singh, Levent Burak Kara

Our approach uses a computationally tractable experimental design method to select number of sample force locations based on geometry only, without inspecting the stress response that requires computationally expensive finite-element analysis.
