Course Name:- 3D Modelling and Printing.

Subject Code:-CUTM3043

Course Description:

In the 3D Modelling and Printing we are providing in this series of courses, students will learn about the evolution of digital fabrication with a full overview of the manufacturing industry and related technologies. Each hands-on, project-based learning (PBL) course will let students design and fabricate 3D objects using computer-aided design (CAD) software and 3D printers. They will experience the design process and become familiar with the advantages and limitations of each 3D printing technology in terms of precision, resolution, and material capabilities. Students will analyze real industry cases, and apply 3D printing technology appropriately while gaining hands-on experience with two leading 3D printing technologies employed in manufacturing today: FDM and PolyJet.


3-D modeling is the use of software to create a virtual three-dimensional model of physical object. 3-D modeling is used in many different industries, virtual reality, video games, 3D printing, marketing, TV and motion pictures, scientific and medical imaging and computer-aided design and manufacture CAD/CAM.

Upon completion of this course, students will be able to:

  • Demonstrate knowledge of key historical factors that have shaped manufacturing over the centuries.
  • Explain current and emerging 3D printing applications in a variety of industries.
  • Evaluate real-life scenarios and recommend the appropriate use of 3D printing technology.
  • Identify opportunities to apply 3D printing technology for time and cost savings.
  • Discuss the economic implications of 3D printing including its impact on startup businesses and supply chains.

Learning Outcomes:

1. Creation of a flexible modelling environment
2. Ability to easily modify models and implement design changes
3. Support for data sharing, and data reuse Knowledge enabled
4. Capture of design constraints and design intent as well as the final model geometry
5. Management of non-geometric as well as geometric design information
6. The 3D Part is the Master Modeler for Drawings, Assemblies and Analyses which are associative to the 3D parts.
7. Apply the unique advantages of 3D printing to their designs.
8. Compare additive manufacturing to traditional technologies and choose the best technology for a given application.
9. Distinguish between various 3D printing technologies and materials and select appropriately for a given application.
