Introduction to 3D Printing
Module 1: Basics of 3D Printing
In the first module, the basics of 3D printing are introduced, explaining how the additive manufacturing process works by creating objects layer by layer from digital 3D models. The history of 3D printing, its applications in various industries such as prototyping, consumer products, medicine, and aerospace, as well as its environmental impacts are discussed. Students are given reflective questions and activities to deepen their understanding of the concepts.

Module 2: CAD for 3D Printing
The second module focuses on Computer-Aided Design (CAD) software for 3D printing, highlighting tools like Autodesk Fusion 360 and Solid Works. Key concepts such as parametric design and Design for Manufacturability (DFM) are explained to optimize designs for 3D printing constraints. The process of preparing files for 3D printing, including using the STL file format and slicing software, is covered in detail with practical exercises for students to apply their knowledge.

Module 3: 3D Printing Technologies and Methods
Module three delves into the types of 3D printing technologies such as FDM, SLA, SLS, and DLP, each with its unique applications and materials. The importance of choosing the right technology for a project based on factors like material choice, accuracy, speed, and cost is emphasized. Students are encouraged to research and compare different technologies and design and 3D print a functional object using their chosen technology.

Module 4: Post-Processing and Finishing
The final module covers post-processing techniques for 3D printed objects, including support removal, sanding, smoothing, painting, and resin cleaning. Common 3D printing problems like print failures and poor print quality are discussed along with solutions to troubleshoot them. Practical exercises are provided for students to post-process their printed objects and troubleshoot common issues, enhancing their hands-on experience with 3D printing.
