  • POLYMER FABRICATION METHODS
    Publication number: 20230287728
    Abstract: There is provided a polymer fabrication method for forming 3-dimensional shapes from a sheet polymer blank (10) by machining at least one re-entrant, elongate groove forming a reduced thickness portion (25) permitting the blank to be folded and having opposed edges (12) at the surface, folding the blank about the groove to form at least a portion of the 3-dimensional shape, the re-entrant of the groove forming an elongate chamber (21) adjacent the reduced thickness portion and opening through an elongate gap (20) between the opposed edges, hot air welding the opposed edges across the gap with filler rod (22), and heating the reduced thickness portion to a selected thermo-reforming temperature via the chamber.
