3D printing lattices: Find the best lattice generation tools!

Posted By on Apr 18, 2018 | 0 comments

If you are using 3D printing, you may know that to get a resistant part, you have to choose the right material. But do you know that design also plays an important role? Choosing the right design for your 3D printed parts will offer you different advantages, and can improve the quality of your projects. We are going to discover how in this blog post, by focusing on lattice design. We will talk about the benefits of lattice structures, indeed, these structural features can improve the quality, and more specifically, the strength of your parts.

We will share with you the best lattice generation tools, both for companies with and without a 3D printing production center. You will also see that our Fabpilot software could totally help you with that!

 

3D printed parts with lattices: Find out the benefits

What are lattice structures?

You may have heard about lattices. It may look like an ornamental design, but it’s much more than that. Indeed, lattice structures are engineering or architectural structures, that significantly help you to improve your 3D printed projects by making your objects lighter but more stronger. This structure uses a crisscross pattern of strips. The lattice designs feature a network of crosshatch sections. There are different type of lattices and it can look like this:

You can print lattices with any technology, such as Selective Laser Sintering or Direct Metal Laser Sintering. To get the best 3D printed part possible, don’t forget to check the design guidelines of the material that you want to use to manufacture your parts. There are many ways to optimize the design of your project, like with jigsaw-structures or voronoi patterns. Today, we are going to see the amazing benefits of lattices.

 

Why should you use lattices?

The design of a part is really important when it comes to 3D printing. When in need of topology optimization, a new design can have a lot of benefits and could really be good for your business. Here is how lattices can help you in your manufacturing process:

It will strengthen your parts

Structural optimization is clearly one of the most interesting aspects of lattices. 3D printing allows to manufacture complex designs, so it is totally possible to print complex lattices: these kind of designs are not necessarily doable with a traditional manufacture technique. An object built with lattices can be really resistant, more flexible or more stress resistant. You will be able to make the most of the power of a functional structure.

It will reduce the weight of your 3D printed parts

Choosing the right 3D printing material will help you to reduce weight. But choosing to print with lattice structures will reduce it as well. Obviously, your 3D printed object will not be full of material or full of powder. The lattice structure will reduce weight, because the object will use less material. A part with lattices can weight only 20% of the weight of the original solid part.

Keep in mind that it is not because the object is lighter that it will be less resistant. As we just saw, the lattice design can help to create really resistant parts! The goal of a lattice structure is to improve the strength of a part with a minimum of material

You will save money

By reducing the amount of material that you need, you will get cheaper parts. Once again, your 3D printed part will not be full of materials, which means that it will reduce the costs! It is possible to print lattices for many diverses projects, with different materials, from plastic to metal. It is good to know if you need a strong part, but cheaper than usual.

How to get lattices: Here are the best lattice generation tools

In order to get great lattice structures, you may have to use a tool that generates lattice structures for you future 3D printed parts. Here is our selection to generate lattices in your solid CAD file:

Autodesk Within

Autodesk Within is an efficient optimization software, it is actually perfect to work on your 3D models before sending them for the 3D printing process. It will optimize and improve the design and structure of your parts.

This tool makes it possible to generate different types of internal lattices. It is also possible to take a look at the global strength of your part and to thicken it where it is needed. This engineering design software is known to be really functional, and it offers various design features. Autodesk Within allows to work on the flexibility and the robustness of your parts.

Here is a demo of Autodesk Within, showing how to get lattices on your 3D model:

 

nTopology

This program will help you to light weight your models thanks to 3D lattice designs. You will  make the most of new design possibilities to optimize your parts thanks to nTopology. You will be able to generate, edit and implement lattices in your 3D model with this tool, using a parametric workflow and functional modeling.

Here is a video tutorial on how to generate lattices for your 3D printing projects using nTopology:

STL Lattice Generator

STL Lattice Generator is a MatLab program, allowing to generate lattice structures on your 3D model in order to 3D print it. This tool can generate different lattices directly in the STL format. It will certainly help you to save a lot of time.

Meshify

Meshify is quite a convenient tool. It is a browser based program, allowing you to upload directly your geometry, generate a lattice structure, and then get an STL file of the result that you can print though a 3D printing service such as Sculpteo. Try out the automatic lattice generation offered by this program!

Simpleware

Simpleware is a 3D software with many different options and one of them is the generation of internal lattice structures. If you are actually looking for a complete program, offering 2D and 3D view and good simulations for your manufacturing projects. This software has been used by Footprint 3D to create soles with lattices! These footwear parts have their design optimized, an ergonomic support and a natural gain, thanks to the lattice structure.

Are there other solutions to create lattices?

3D modeling software

Some 3D modeling software have features allowing to create internal lattice structures, but it will not necessarily generate 3D lattices automatically. But if you are quite experienced with 3D modeling, and if you don’t want to use different programs to create your project, programs such as the CAD software Creo may totally fit your needs.

Fabpilot by Sculpteo

If you are working in a 3D printing factory, you should check Fabpilot, the software that we developed here, at Sculpteo. Fabpilot is a cloud-based software that will help you to manage your 3D printing production. You will be able to work on your project preparation, your production and your operations management with just one software!

Among the diverse possibilities and features offered by Fabpilot for the project preparation, you can find a great lattice generator.

How to print my 3D model with lattice structures?

To print your 3D project with lattices and get a high quality result, we recommend you to use professional 3D printers through a 3D printing service instead of investing in one of these expensive 3D machines. If you are looking for additive manufacturers, you can choose an online 3D printing service. At Sculpteo, we print your parts with lattices and deliver you high quality products. We are offering a wide range of different 3D printing materials. From plastic and resin to metal 3D printing, make your choice!
