This tutorial was created for MeshMixer users who are interested in 3D printing. It provides an overview of the essential information required to create a printable model using this indispensable 3D printing modeling software. It is particularly useful to correct files designed for 3D printing.

In this tutorial, you will learn the best practices for modeling and correct and export an object for 3D printing using MeshMixer. At the end of this tutorial, you will learn how to:

Then, you will be able to upload your 3D file on our website and 3D print it!

MeshMixer is a free 3D modeling software that allows you to easily create and correct 3D models. It is ideal for creating 3D models on the basis of existing volumes, which are combined using easy-to-use tools.

You don’t have to be an expert or know how to use the software in great detail to understand this tutorial. However, it is important to master the software’s basic functionalities beforehand, as we will focus only on the tools and modeling best practices to ensure successful 3D printing. For this reason, we will not have the opportunity to explain MeshMixer’s modeling basics exhaustively.
