Abstract
The invention discloses a generating method for multiple contour scanning paths for additive manufacturing. The generating method comprises the following steps: S1: slicing a to-be-printed component 3D model to obtain model planar data; S2: according to the planar data, obtaining current contour data and current non-contour data of a current layer; S3: according to the current contour data, generating one or more contour scanning paths, which are biased in a filling direction, in a contour direction; S4: according to the current non-contour data, generating a non-contour scanning path in a random angle of inclination or a fixed angle of inclination; S5: according to planar data of the next layer of the current layer in S2, obtaining contour data of the next layer, and generating one or more contour scanning paths, which are biased in the filling direction, in the contour direction; S6: according to the planar data of the next layer of the current layer in S2, obtaining non-contour data of the next layer, and generating a non-contour scanning path along a random angle of inclination or a fixed angle of inclination; S7: repeating S5 and S6 until obtaining scanning paths of whole model planar data. The generating method overcomes the defect that component surfaces are rough.

Increase many profile scans path generating method that material manufactures, it comprises the steps:
S1: to needing the 3D model printing part to cut into slices, obtain the panel data of model;
S2: according to panel data, obtains the current outline data of current layer and current non-outline data;
S3: according to current outline data, generates one or more to filling biased profile scan path, direction along contour direction;
S4: according to current non-outline data, generates a non-profile scan path along arbitrary angle or fixed angle;
S5: according to next layer plane data of S2 current layer, obtains the outline data of lower one deck, and along contour direction one or more to filling the biased scanning pattern in direction;
S6: according to next layer plane data of S2 current layer, obtains the non-outline data of lower one deck, generates a non-profile scan path along arbitrary angle or fixed angle;
