Answer to Question 1

The weight of the resin determines the wall thickness. The wall thickness has a major effect on the length of the heating cycle. Because plastic is not a good thermal conductor, even small increases in thickness required disproportionate times for heating. If the heating is too long, degradation can occur. If the thickness increases without the knowledge of the machine operator, the last material to adhere to the surface may not get hot enough to fully fuse. Therefore, small changes in weight can affect the heat cycle and part physical properties.

Answer to Question 2

A poorly fused part may have any of the following: bubbles on the inner surface, bubbles inside the walls, pin holes on the outer surface, non-shiny inner surface, and poor color development.
