Four Main Steps to Prepare Your Blender file For 3D Printing

The main topics Chris covers in this tutorial are the following common file preparation problems:

1. Define the right model dimensions: You will learn how to specify the right dimensions for your 3D model by adjusting scale and units of measurement.

Choosing the right dimensions is key.

2. Join meshes together: Chris will show you how to create one solid object by combing several separate parts together. He will demonstrate two ways of doing that: manually or with the help of Booleans.

3. Make it watertight: Making sure that there are no holes in your mesh is important. You will learn how to check if your model is really “manifold” and does not have any gaps in its surface.

4. Make it smooth: At the end of the video, Chris will show you how to use Subdivision Surfaces (Subsurf in short). It’s a method of subdividing the faces of a mesh to give your object a smoother appearance.
