3D Design and 3D Printing (Ages 10-14)

From modelling in Tinkercad to printer settings: key rings, robot parts and a prototype of their own invention.

In this programme students learn to turn an idea in their head into a three-dimensional model on screen and then into an object they can hold. We start with basic shapes in the browser-based Tinkercad and move on to dimensioned technical drawing and, at the advanced stage, parametric design.

How the sessions work

  • One 90-minute session a week, with no more than 8 students
  • Measuring, using callipers, tolerances and interlocking parts
  • Slicing software: layer height, infill and support structures
  • The academy has four FDM 3D printers using PLA filament

Projects

In the first month students design a name key ring and a pencil holder, in the second month spare parts for robots, and in the last month a prototype that solves a problem they have chosen themselves. Each student has two prints a month and takes them home. The printers are enclosed, and an instructor supervises printing so that students do not touch the hot nozzle.

Learning outcomes

  • Dimensioned 3D modelling
  • Slicing and print settings
  • A prototype of their own invention
