Introduction to 3D Printing
6 Hours (6 Sessions)
Beginner / Introductory
Live Demo & Hands-on
This course provides a comprehensive, hands-on introduction to 3D printing and additive manufacturing. Learners progress from understanding digital 3D models and slicing parameters to operating printers responsibly, troubleshooting common failures, designing functional household items, and evaluating real-world applications. Emphasis is placed on responsible 3D printing, material behavior, print reliability, and informed decision-making.
Learning Outcomes
By the end of this course, participants will be able to:
- Prepare, slice, and print 3D models using an FDM 3D printer.
- Operate a 3D printer safely and responsibly.
- Identify and resolve common 3D printing issues.
- Design simple functional objects with correct measurements and tolerances.
- Select appropriate materials, settings, and printers for intended use.
- Explain the role of additive manufacturing in modern production.
Mode of Instruction
