The emerged "Bones like" structures are pretty impressive. With certain constraints, a "connected bones" structure emerged, which similar to humans and birds in the examples presented in this video. However, this work seems to focus on the optimation method, and I am pretty interested in the optimized problem. Are there some references?

What if the wing did not have constrained size? Could dramatically better wing be achieved?

This is really impresive, where/when would us be able to use this tool?

Amazing. But are those filaments really useful, for an elastic problem ? I mean it's probably what limits the manufacturing. Is there a way to put a limit for the thickness ?

[@hashkenhabib]

I think they do load distribution, which is intuitively what comes out when you simulate such structures with/without fine structures - the local stresses are much lower with the fine structures present. But good question, I am also puzzled how much is the structure a true optimum vs how much does it arise as an 'artefact' of the algorithm

Hello! This looks amazing, how could one implement this code in practice? and would it be possible to export the end product to a popular CAD modelling software in formats such as STL or OBJ? Thanks.

This research could change the way we design everything - Bridges, wheels, tall buildings, space stations and 3D printed components.

Sorry you are are 30 years to late. The basic algoithm was discovered in the 90ties and is widely used in industry for decades. What is impressive here is the resolution.

@@jessicaklement656 Making it more efficient and more accessible is also revolutionary in the sense that use may become widespread because of it.

[@Riley_Christian]

when will this finally be useable?? We really need an alternative to the expensive proprietary solutions

Like a crab's exoskeleton

soooo cool. way underated. thanks

[@osc766]

how do you do the cut away animation?

[@yourcommentmightnotworksop9987]

looks SCI FI

[@cheeseboy8241]

kinda spooky

[@nedisawegoyogya]

how soon the code will come? we're already in 2020

You can find some 2D implementations here github.com/zfergus/topopt
