Lesson notes

Learning Objectives

Indicator: 3.2.2.LI.1 - Explain powder-based prototyping technology in manufacturing.

By the end of the lesson, learners can:

Define powder-based rapid prototyping and state at least two distinct technologies that fall under this category.
Describe the step-by-step working principle of selective laser sintering (SLS) and three-dimensional printing (3DP) using accurate technical vocabulary.
Compare powder-based rapid prototyping with the solid-based and liquid-based technologies studied in previous weeks, identifying at least two key differences.
Discuss at least three advantages and two limitations of powder-based rapid prototyping in manufacturing contexts.
Research, in mixed-ability groups, a real-world application of powder-based rapid prototyping and present findings clearly to the class for feedback.
