Lightweighting a bracket for the NASA EXCITE Challenge

The automotive and aerospace industries have used hollow structures for decades to create lightweight but stiff parts. With additive manufacturing, we can take that concept to the next level and create hollow parts with a variable shell thickness and lattice infills that result in even lighter high-performance parts.
Today’s design problem for the A15 benchmark comes from the NASA EXCITE mission. The goal was to minimize the bracket’s weight and make it as stiff as possible while withstanding the forces applied during flight.
In this video, Yuki Okada, Technical Marketing Specialist at nTop, shows you how to set up and run a Field Optimization, a new generative design technology that allows complex geometries, such as lattices, to be optimized at every point. He will run through a topology optimization and Field Optimization setup to get a final optimized part, which will then be exported using Implicit Interop and our nTop Plugin for EOSPRINT.
Watch and learn how to:
• Set up topology optimization and Field Optimization
• Understand the Field Optimization results
• Export the final part using Implicit Interop

Why doesn’t anyone teach how to use the software? They just come to show what we did. Where can I learn?

I love how biological these topology optimized part look.

[@hannesaltenfelder4302]

Thick outer shell, thin inner structure. I like how most optimized parts look similar to bones.
It would be nice if there was a free online-service or an easy-to-use tool available.
Most free programms only scratch the surface and take way too long.
