NEW Volumetric Lattice in Fusion 360 - Suggested Workflow

In this video we will dive a bit deeper than just a first preview of the tool and look at how to edit a created lattice, convert it to a mesh and understand where the current limitations are with the tool.
Remember that this is brand new and in preview right now so this is the best time to play around with it and provide valuable feedback to autodesk!

This is massive for 3D printed parts' optimisation. Thx ! I've tried playing with various slicers on this, but it doesn't reach this level of detail.

Glad it helped!

I notice that it seems possible to make a lattice which doesn't fit into the boundary geometry evenly, meaning that you can have broken trusses between the centers of cells dangling at the edge of the boundary. Is there any way to force the cell size to be adaptive so that your parts walls don't have any of these features? I see that for relatively simple geometric objects it should be possible since you can scale the cell size in any axis, and it would seem that you can change the orientation. But lets say I had a lofted circle along a spline that lofted across a variety of different sized circles, giving me a circular cross section with a smoothly variable radius throughout. How would I be able to ensure I have no areas where the walls have open dangling cell edges?

Hey Alex, unfortunately I do not believe it takes into account the boundary in terms of orientation or constraints of the lattice that is being created. It is coordinate system based. You can notice this if you generate a lattice then use Move to move the body in a single direction. the lattice stays. The actual lattice, at this time, isn't created until you convert it to a mesh. So this means centering your volume around the origin seems like the best way to ensure a consistent fill, assuming your part had some sort of symmetry. With your example of a lofted circle, the cells are still based on the XYZ of the design and not twisted or conformed to the loft/sweep. While not exactly the same something like this tool apps.autodesk.com/FUSION/en/Detail/Index?id=1872190273770570241&appLang=en&os=Win64 could be an answer. I am sure Autodesk will continue to develop the Lattice tool and its functionality. I have given my suggestions and will wait for an update. I have 3d printed a hand full of designs using this lattice tool and do have plans to cover a workflow with it soon but I am working out a "real world" workflow and not just a "look at this" sort of thing.

If you look at properties once you have defined the volumetric latticing, do you get mass properties for the latticed body or the original solid body?

[@LearnEverythingAboutDesign]

Currently the lattice you see on screen is only a visual reference until you right click on the body and convert it to a mesh. Once you have a mesh you could "technically" convert it to a solid using the mesh conversion tool to a faceted solid body. That would let you get the mass. But at this time you would get the properties of the original solid body.

I can generate lattice structure using volmetric lattice in Fusion 360; however, I couldn't render any lattice in Fusion 360. Do you know how to do it? Thanks

[@LearnEverythingAboutDesign]

The lattice in Fusion is a graphic until you convert it to a mesh. When its a mesh it maintains the external main body as part of the feature. If you just show the mesh result you can render it BUT you are dealing with a mesh body now. While rendering typically uses a mesh to calculate the light/reflections, rendering a mesh might be less than ideal unfortunately. BUT you should be able to convert the graphical vol lattice into the mesh body by right clicking on it, then render that.

​@@LearnEverythingAboutDesign Many thanks for your response. I did try to convert lattice structures into mesh. However, after meshing (using the most refined mesh setting in Fusion 360 on my supercomputer), even a simple 50x50x50 mm simple cube filled with 3 mm- GYROID cells was transformed into a smooth-surface- cube (i.e., lost its lattice structure due to meshing)

[@LearnEverythingAboutDesign]

hmm that is strange. I tested it out on my end and was able to render the lattice. If you can share the file you can email me [e-mail] and i can take a look.

[@lyhuyanh]

@@LearnEverythingAboutDesign Thanks very much. I have emailed you the file.

Home version ??

[@LearnEverythingAboutDesign]

Unfortunately not Fabrice. The Extensions are only available for EDU or commercial licenses. There is a fusion 360 app you can get from the app store to let you do some lattice creation. apps.autodesk.com/FUSION/en/Detail/Index?id=1872190273770570241&appLang=en&os=Win64 There is also a sketch generator apps.autodesk.com/FUSION/en/Detail/Index?id=1006119760063675415&appLang=en&os=Win64&autostart=true These should work fine for the home/hobby license version.

[@foxtrottone]

@@LearnEverythingAboutDesign Dommage ! Et merci pour les liens, je vais essayer

[@LearnEverythingAboutDesign]

I plan to cover that free one in an upcoming video, maybe tomorrow.

[@eedesign878]

I am not sure you understand properly this.

What do you mean EED?
