2.5. Disadvantages

Try these first

1. 1.

   What is a key limitation of FDM in terms of part quality?

   Hint

   Consider the visual quality of the parts.

2. 2.

   What materials does LOM mainly use?

   Hint

   Think about the type of layering technique.

3. 3.

   What disadvantage is associated with FDM?

   • High resolution
   • Low material cost
   • Poor surface finish

   Hint

   Think about the aesthetic aspect of printed parts.

4. 4.

   True or False: LOM is suitable for creating complex internal geometries.

   • True
   • False

   Hint

   Consider what types of shapes can be practically made using sheets.

5. 5.

   Consider a project where dimensional accuracy is vital, like creating a functional prototype. Discuss the implications of selecting FDM over more precise technologies.

   Hint

   Focus on the project outcomes and industry standards for prototypes.

6. 6.

   Evaluate a manufacturing scenario where mixed materials are needed. Would you advise Ultrasonic Consolidation or Gluing techniques, and why?

   Hint

   Think about the material properties and application requirements.
