BUILDING AND ATTACHING SUPPORT STRUCTURES FOR 3D PRINTING

Method(s) include projecting a support toolpath into a current layer of a model, removing any pieces within an expanded version of a current boundary of the model, generating a support toolpath for the current layer, adding a height increase to portion(s) of model toolpath(s) for the higher layer of...

Beschreibung
Zusammenfassung:	Method(s) include projecting a support toolpath into a current layer of a model, removing any pieces within an expanded version of a current boundary of the model, generating a support toolpath for the current layer, adding a height increase to portion(s) of model toolpath(s) for the higher layer of the model that overlie the support toolpath generated for the current layer, connecting the support toolpath and the projected support toolpath to form a connected support toolpath, overlaying the connected support toolpath with a next boundary of the model in a lower layer of the model, adding a height increase to portion(s) of the connected support toolpath that fall within the next boundary of the model in the lower layer of the model, and repeating the process through layers of the model to form support toolpaths for support walls for the object to be manufactured by the extrusion printer.
