Title: ADDITIVE MANUFACTURING SYSTEM WITH SLIDING THERMAL ISOLATOR
Abstract:
An additive manufacturing system (10) includes a build chamber with at least first and second side walls and top and bottom walls. A central deformable, thermal insulator (30) has a first edge (32) and a second edge (33), where a print head carriage (31) is movably retained within the central deformable thermal insulator (30) and is configured to move print heads (204, 206) within a build plane of the build chamber under control of a gantry. The system (10) includes first and second dynamic thermal barriers (12, 14) each having a length between a proximal edge (16, 116) and a distal edge (18, 118) wherein the proximal edge (16, 116) is configured to be secured to the central deformable insulator (30) and a distal edge (18, 118) is configured to be movably retained to the build chamber such that as the print head carriage (31) moves laterally across the build plane, each dynamic thermal barrier (12, 14) moves with the central deformable insulator (30) and print head carriage (31), and retains its length.
