Systems And Methods For Temperature Control In An Additive Manufacturing Process

摘要

Systems and methods for forming a three-dimensional build object on a substrate include controlling an energy beam source in a first mode during a first processing step during which additive material is deposited. Additionally, the method includes controlling the energy beam source in a second mode during a second processing step during which additive material is not deposited. During the first processing step, a feature may be formed by melting additive material as it is deposited into a target area. During the second processing step, the target area may be preheated or reheated to control temperature gradient
