Introducing Lattice in NX

With the rise of additive manufacturing (3D printing) in product development today, many designers will be excited to hear there is a new Lattice command in NX.

  

Lattices are complex geometrical structures used to lightweight and strengthen components. They give structural integrity to designs while reducing the amount of materials used in the finished product. All great things to have when we’re talking about product development.

Lattices are produced by additive manufacturing. Due to their complex geometrical nature, it’s virtually impossible to create lattices using traditional techniques – be it design or manufacturing. That’s why the Lattice command is so important for designers: It gives you a way to automatically generate these structures within the parameters you set so you can reap the benefits of a lighter, stronger design. The Lattice command even works on topology optimization results.

 

Let’s look now at how you would use the Lattice command in a design workflow in NX. The example shown here was first presented at our PLM Connection Americas event this year in Indianapolis by my colleague Paul Bevan.

We start with our model—in this case, it is an elevator bell crank—and from the Additive tab of the NX Modeling application, select Create Lattice. Use the selection tools to specify the area within which you wish to generate the lattice.lattice nx 11.0.2 2.jpg

 

Next, you are given options to specify the lattice’s appearance and density. You can select from many different cell types and specify the cell edge length and rod diameter. You can also specify the placement and orientation of the lattice.

Once all of the parameters have been set, you are ready to generate your lattice.lattice nx 11.0.2 3.jpg

The resulting lattice the command generates is a faceted body. To combine the lattice structure with the surrounding geometry of the part, simply use the Unite command. This will create a single convergent body that you can then change with Convergent Modeling.

This command demonstrates just one of many ways NX helps you stay ahead of the competition by leveraging new design techniques that make for lighter, stronger and more affordable products.

The lattice command was introduced in NX 11.0.2

Can you tell me what license is required for using the lattice command in modeling?  I've updated to 11.0.2.7 and I see the command in the modeling tab (although I can't find the Additive tab as shown in the video above).  I have the Mach 2, Advanced Designer and P1 bundles available to me.

 

Thanks!

Hi Matt,

That was a prototpye version of the software. If you want the lattice design function you need to add either

 

NX Lattice Structures Design FL [NX30220] (Floating license)

 

NX Lattice Structures Design NL [NX30220NL] Node Locked)

 

You may also want to take a look at

 

NX Additive Design with Convergent Sticky Add-on [NXS30110]

 

This gives you more enhanced capability to work with facet/convergent bodies.

Hi Paul,

I am trying to simulate an imported lattice structure (as 1D elements) and already applied forces and constrains. Can you tell me how I can assign a material to the 1D structure?

Would be glad to receive a response soon,

Hi Alex,

I have passed your question on to someone in our Simcenter group who can provide an appropriate answer.

Come on! Even CAD is going forward with micro-transactions? Smiley Happy

...many designers will be excited to hear there is a new Lattice command in NX... yes I was. And now I am annoyd its actually a paid add-on. And this information is not even in an article, but in the comments below. Thats just sad.

hi dziubelis,

The technology currently employed in creating the lattices is from a partner of ours so I assume we have to pay a royalty to them. This is probably one reason why a charge is made for the license. In general we provide numerous enhancements, improvements and new capabilities which are included in our software releases which are covered by the maintenance you pay.

Alex / Paul,

 

Adding material assignment to beam elements is very simple. Follow the process shown in these 3 images. Alternatively you could assign a material to the geometry (if there is any) and make sure the property is set to "inherited".
