1.3. Laser and Laser Scanning

Try these first

1. 1.

   What is stereolithography (SLA)?

   Hint

   Think about the relationship between 3D models and physical objects.

2. 2.

   Name a key material used in SLA.

   Hint

   What materials cure when exposed to light?

3. 3.

   What technology does SLA primarily utilize to solidify resin?

   • Ultrasound
   • Laser
   • Heat

   Hint

   Think about how the process is described.

4. 4.

   True or False: Photopolymers are solid materials used in SLA.

   • True
   • False

   Hint

   Consider the state of photopolymers before they are cured.

5. 5.

   Describe a scenario where the choice of photopolymer affects the outcome of an SLA printed part. What properties would be paramount to consider?

   Hint

   Think about the application's requirements like mechanical strength or flexibility.

6. 6.

   Analyze the impact of layer thickness on the detail and strength of an SLA printed part. How would you optimize the settings for a specific application?

   Hint

   Consider the trade-offs between time and quality.
