HEAT-AWARE TOOLPATH REORDERING FOR 3D PRINTING OF PHYSICAL PARTS

摘要

A computing system (100) may include an access engine (108) and a toolpath reordering engine (110). The access engine (108) may be configured to access an original layer toolpath for slice of a 3D CAD object as well as a heat criticality measure (240, 340, 540) for the original layer toolpath. The heat criticality measure may specify a heat impact for different points on the multiple toolpath segments of the original layer toolpath for the 3D printing of the physical part using the original layer toolpath. The toolpath reordering engine (110) may be configured to reorder the multiple toolpath segments into a modified layer toolpath (250, 350, 550), and the modified layer toolpath (250, 350, 550) may have a heat criticality measure with a lesser heat impact on the physical part than the heat criticality measure (240, 340, 540) for the original layer toolpath.
