List at least three advantages and disadvantages of a powder-bed laser sintering process.

Solutions

Expert Solution

The following are the adcantages and disadvantages of  a powder-bed laser sintering process.

ADVANTAGES

1) Highly complex part can be fabricated with dimensional accuracy.

2) The made by this proces do not require post curing

3) There is no need to create a structure to support the parts

4) Whenever needed the modification in design can be easily done

5) Different kind of material can be selected

DISADVANTAGES

1) Due to thermal distortion defects like shrinking and warping in fabricated part can develop.

2) Surface is comparatively rougher than those of machined surface.

3) The devive and machine parts used are quite expensive.

4) powder may be hardened at the border line due to additional powder.

5) The strength is weaker in Z direction need spcecial care to handle the product.
