摘要： According to various aspects and embodiments described herein, a method for optimizing a three-dimensional (3D) printing process comprises receiving 3D data characterizing a target 3D part, generating a 3D part mesh based on the received 3D data, generating a Signed Distance Field (SDF) based on the 3D part mesh, performing a predictive analysis using the SDF to generate a predicted error field, calculating a correction field based on the predicted error field, applying the correction field to the 3D part mesh to produce a corrected 3D part mesh, creating a corrected 3D print profile using the corrected 3D part mesh, outputting the corrected 3D print profile to a 3D printing device, and printing a corrected 3D part using the 3D printing device and the corrected 3D print profile.

摘要： According to aspects, provided is a method for displaying a three-dimensional geometry of a part to be 3D printed, comprising receiving the geometry of a part sliced into shells or layers, displaying the shells or layers, displaying, for a shell or layer, a representation of a distribution of a isotropic fill material, displaying, for an anisotropic fill subset of the set of shells or layers, a representation of a distribution of an anisotropic fill material having an anisotropic characteristic oriented relative to a trajectory of an anisotropic fill tool path, receiving a selection, from among the displayed shells or layers, of an editing subset, the editing subset including part of the anisotropic fill subset, and regenerating, for a shell or layer of the editing subset, one of a second representation of a distribution of isotropic fill material and a second representation of a distribution of anisotropic fill material.

摘要： In a 3D composite printer, toolpaths defining fill material shells are received, as are toolpaths defining support material shells. A 3D toolpath defining a long fiber composite material curved shell is also received. A fill material deposition head traces the toolpaths to deposit some of the fill material shells or support material shells at least in part non-parallel to a printing substrate. A long fiber deposition head traces the 3D toolpath at least in part non-parallel to the printing substrate to deposit the long fiber composite material curved, concave, ring, tube, or winding shells to enclose, surround, or envelop at least a portion of the fill or support material shells.

摘要： In a method for additive manufacturing, a multi-strand core reinforced filament including a flowable matrix material and substantially continuous reinforcing strands extending in a direction parallel to a length of the filament is supplied. A first consolidated composite swath of a height less than ½ the width of the filament is deposited in a first reinforcement formation including at least one straight path and at least one curved path against a deposition surface, and a second consolidated composite swath of a height less than ½ the width of the filament is deposited in a second reinforcement formation against the first consolidated composite swath. Each deposition flows the matrix material and applies an ironing force to spread the reinforcing strands within the filament against the underlying surface and/or previously deposited swath.
