Nice free tool for creating Lattice Structures

by RobotMama

I tested nTopology for creating lattices as an experiment. Here is the text from my article I created for the topic.
And here is the things I created for testing different types of structures. https://www.thingiverse.com/thing:2788117

Lattice structures normally are intended to optimize functional parts by making them light-weight and strong by filling the inside with a complex structure. This is used in aerospace technology to save on fuel while flying and still maintaining structural integrity and strength of the parts that are optimized.

Nowadays these structures can be achieved with metal 3D printing (laser sintering, laser melting and the like). But these structures are also interesting from a design perspective. The pure beauty of them inspires to use these structures in architecture, fashion or other fields.

Here are my tests with different topologies, printed on a Formlabs Form2 (SLA printing) with clear UV resin. If you want to create your own structures head over to NTopolgy (https://www.ntopology.com) they have a beautiful free tool for that.

You will find more footage next week on my Instagram, Facebook and Youtube accounts.

I hope you got inspired like me and get hands-on designing. Let me know in the comments what projects you came up with.

Cheers RobotMama.

auxetic 3D macrostructure?

by Mixomycetes

Hey, does any of you know of/have a model for a 3D lattice that is auxetic? This means it has a negative poisson ratio, so if you compress it in one direction, it compresses in another too?

I know of this design*, but that is 2D, i am looking for a 3D alternative, with 2+ axes (3 or more)

After a bit of research, i found a few structures. will add an openscad file later this week.

Siggraph 2015

by qnzhou

Dear all,

We are presenting our research work on fabricating microstructures next week in SIGGRAPH 2015. If anyone is in LA region, I would love to meet you and show you our samples. Our research is much more than just fabricating elastic structures, find out more at our project web page:

Elastic Textures for Additive Fabrication:
