Question

2. Identify one comparative advantage and one limitation of additive manufacturing.

3. Explain how selective laser sintering and 3D printing processes are different?

4. Describe fused deposition modeling briefly.

6. What it is important to develop prototypes.

Answer 1

Difference ce between selecting Laser sidering and 30 printing CA 30 printing powder Located in a build Chamber. deposits A printing head a liquid binder on to the powder, thus it is binded together and a Layor of past is formened. Then the built pratfoom is lowered to the disteencé equal Size layer formed Tais process is repeated to Empleta While in selective Carex sintering the powder material is binded by a berger y laser Due to the heat heat a Caser theo material & heated and bonded together by forms layer Fence this process binding achieved through Sistering to to the 32 post. fusion and cs
