  • Publication number: 20220161496
    Abstract: The invention relates a material extrusion additive manufacturing method for producing a clear, internally transparent part composed of amorphous thermoplastic polymer layers at least 0.1 mm thick. The invention also relates to internally clear parts made by the method, having an internal haze of less than 25%, less than 15%, less than 10% and even less than 5%. The method creates a printed dot or line of amorphous thermoplastic polymer that remains at a high internal temperature for a long enough period of time to allow the polymer chains in each layer to be mobile and fluid, permitting sufficient inter-layer chain entanglements to reduce and eliminate layer lines. With a nearly 100% dense final part, voids are eliminated. The resultant printed article has a very high internal clarity, and can have a haze of less than 5%.
