Abstract (en)

[origin: WO2023086250A1] A method for 3D printing a part with an additive manufacturing system includes printing a first portion (302)(308) of a part (342) in a layerwise manner and analyzing a topology (344) of the first portion (302)(308) of the part. The method includes determining a tool path for printing a second portion (306) of the part on a surface of the first portion (302) of the part (346), and pre-heating the first portion (302)(308) of the part along the tool path as a function of the topological analysis of the first portion of the part (348). The method includes printing the second portion (306) of the part along the tool path (350).
