Episode 1 - Infill pattern & density

mceclip0.png

Episode summary

Infill is one of the most important parts of 3D printing. It determines the strength of your part, the print time, and the amount of material you need for your print.

Yet, even the most advanced users often do not fully understand the concept of infill and the many choices available for tuning.

This episode takes a close look at infill: what is it, why do you need it, and what options do you have. We explore three totally different applications, and explain why those infill settings were set the way they are.

After this episode, you'll know how to select the right infill pattern and density for your application, and you can replicate the examples shown in the episode easily by downloading the assets below.

Cheat sheet

This cheat sheet helps you to quickly determine which infill settings are right for your specific needs: depending on the model, purpose, and material used.

Settings Guide on infill patterns

We highly recommend that you install the Settings Guide plug-in. It gives you a hover-over detailed explanation of every setting in Ultimaker Cura. Find the plug-in here.

The content for Infill Patterns can also be found on Github.

Model and Project files

Below you can download model and project files for all sample applications shown in the episode. All files are 3MF files. The 3D model file contains only the part (STL) and can be opened in Cura for any printer type. The project files are also 3MF files, but contain the tunings in infill settings that we showed during the episode, available for all Ultimaker printers.
