1. Powder Bed Fusion (PBF) Processes

Try these first

1. 1.

   What is the main purpose of Powder Bed Fusion (PBF)?

   Hint

   Think about how layers of material create a finished product.

2. 2.

   Name one material commonly used in PBF.

   Hint

   Consider the types of materials in 3D printing.

3. 3.

   What process is primarily used for melting metal powders in a vacuum?

   • Selective Laser Sintering
   • Electron Beam Melting
   • Direct Metal Laser Sintering

   Hint

   Think about what happens in a vacuum environment.

4. 4.

   True or False: Unfused powder can act as support during PBF processes.

   • True
   • False

   Hint

   Consider the role of powder that isn't fused.

5. 5.

   Design a PBF process for producing a custom dental implant, considering the types of materials and processes you would use.

   Hint

   Think about biocompatible materials and the types of processes that ensure accuracy.

6. 6.

   Evaluate the impact of high residual stresses on the components produced via PBF and how they can be mitigated.

   Hint

   Consider how adjusting parameters during the process can directly affect the end product's integrity.
