Intermediate Lesson 9 – Different types of 3D Printers

Intermediate 3D Printing

Recommended age range 14 – 16

In this lesson you classes will learn about the different types of 3D Printers currently being used by schools, designers and engineers. These include FDM, SLA, SLS and DLP technology. Students will learn the technical differences between the printers and the properties that each printer delivers in printed outcomes. They will also learn how the material for 3D Printers is made and what an extruder is.

Lesson resources include;

  • Lesson plan
  • Lesson powerpoint
  • Lesson tasks with answer sheet
  • Homework tasks with answer sheet

This lesson will advance your students understanding of how different 3D Printers work and the technical differences between them. Students will learn the difference between Filament 3D printers and resin and powder 3D printers and the differences in the technology behind them. They will also learn about extrusion and how filament is made through this process and how filament is extruded through a nozzle to form a layer of a 3D Print. Included is a link to 2 youtube videos to support the learning, one on how SLA 3D printing works and then other on how filament is made by extrusion.

This lesson broadens your learners knowledge of 3D printing, beyond filament based machines and covered topics that allow for an understanding of how industry use the technology and comes complete with lesson worksheets and homework sheets.

Lessons include a starter task, main lesson tasks, plenary tasks and associated homework tasks. The lesson tasks and home work tasks can be peer or self assessed by students within the lesson. This will help deepen the understanding of the topic as feedback to their answers is within the lesson.
