Model and Assemble a 3D Printer Z-Axis

The Z-axis of a desktop 3D printer is the main support gantry of the unit. The Z-axis facilitates the vertical movement of the X-axis and the Y-axis assembly is mounted to the Z-axis. Therefore, the design and engineering of the Z-axis are key to the overall stability and performance of a desktop 3D printer. As such, there are many different designs for a 3D printer Z-axis and multiple ways of building them. In this course, we'll model a Z-axis design based on the original open source RepRap and Prusa models, which will give you an advanced understanding of Z-axis components, mechanics, and construction.

Using 2D sketching, 3D parametric modeling, and assembly modeling, we'll model and assemble the 3D printer Z-axis using Autodesk® Fusion 360™. In doing this, we'll also learn how to model and manage complex assemblies, linking assemblies and components to the 3D printer Z-axis assembly, as well as inserting off-the-shelf components from McMaster-Carr. We'll also use CAD techniques to project existing geometry onto planes and surfaces to create new geometry and we'll use assembly modeling techniques to position components and create motion.

After completing this course, you'll be able to:

  • Manage complex assemblies.
  • Insert and link assemblies and components into the current design.
  • Create, copy, and move components.
  • Insert Components from existing datasets and McMaster-Carr into the current design.
  • Use 2D sketching techniques to project existing geometry onto planes and surfaces.
  • Use 2D sketching and 3D parametric modeling techniques to edit sketch geometry and create 3D component parts in Fusion 360.
  • Use assembly modeling techniques to position components using rigid joints as well as create as-built joints with motion
