How long in minutes would it take to fabricate a 4 colored ball 6 cm in diameter using FDM? Assume a layer thickness of 0.3 mm, a width of 0.7 mm, and the extrudate being deposited at a rate of 3.5 cm/sec. The stage movement time is 0.6 sec per layer, and it takes 5 sec to switch between any two materials.
Oct 10, 2016· Use of a VFD can protect machinery from damage and protect the process or product (because the amount of torque being applied can be controlled accurately). An example would be a conveyor jam. If just an AC motor connected, the motor will continue to try to rotate until the motor's overload device opens ( due to the excessive current being ...
