As Christmas approaches now is the time to start thinking about the festive season. Why not develop and test out your 3D design skills to create some festive 3D printed decorations, such as this cute snowman decoration.

This tutorial developed and kindly shared by Alastair Jennings will guide you step-by-step through the process of drawing the snowman using Autodesk 123Design 3D modelling software.

Objectives

 

  1. How to use 123D Design
  2. How to work with Primitives
  3. Using Combine to Merge and Subtract shapes
  4. Exporting a 3D model ready for print
  5. Configure Cura to print a Christmas decoration

The tutorial provides a good introduction to using the 123Design interface and some of the software features as well as guiding students through the process of creating a finished design that they can import into Cura, slice and then 3D print.

An .STL file of the finished design is also available to download to allow you to print an example to show the students, or students can open this into 123Design and edit the design to personalise it.

In The Classroom

This tutorial provides a good introduction to using the 123Design interface and some of the software features as well as guiding students through the process of creating a finished design that they can import into Cura, slice and then 3D print. It is perfect for beginners as it takes them step by step through the process, but is also sufficiently challenging for intermediate users of this software.

When students have finished the tutorial, they can be challenged to personalise their designs, for example by adding a hat or other accessories. Students can also develop and print new designs for Christmas ornaments to complement the snowman.

This project could be adapted into a business enterprise activity as multiple decorations could be 3D printed. Students could market and sell these at the school Christmas fair or to other pupils in school.
