Abstract:
A component includes a support structure made with an additive manufacturing process with a first end and a second end, and an object made with an additive manufacturing process with a first end and a second end, where the first end of the object is attached to the second end of the support structure. A cross-sectional area of the first end of the object is larger than a cross-sectional area of the second end of the support structure. A method of making an object, the method includes manufacturing a support structure with an additive manufacturing process. An object is manufactured on top of and connected to the support structure with an additive manufacturing process, wherein there is a witness mark created between the support structure and the object. The witness mark is identified. The object is separated from the support structure along the witness mark.
