  • Patent number: 12180360
    Abstract: The invention relates to heat treatment of polymorphic semicrystalline or crystallizable polymers to increase the content of the highest melting crystalline form. Such heat treatment results in a polymer powder that has a consistent, uniform melting range, improved flow and improved durability of the powder particle size for applications that require powder flow at elevated temperatures. In addition to improved powder properties, the articles produced from the powders also exhibit better physical properties in both appearance and in mechanical properties. Thus the invention also includes polymer powders and articles produced by the described processes.

  • Patent number: 12151434
    Abstract: The invention relates to thermoplastic filament for use in 3-D printers, in which the core of the filament is non-solid or mono-filament. The filament may contain a multitude of small micro-voids, (a micro foam), be a foam-core structure, be hollow, or have a monofilament core. The filament of the invention is especially useful with crystalline and semi-crystalline polymers, and reduces the negative effect of filament voids, formed by shrinkage during the cooling of the filament.

  • Publication number: 20240262031
    Abstract: The invention relates to the use of a compatible thermoplastic material (film, sheet, or raft) as the base sheet or layer for 3-D printing an article. The use of the base film provides a means of printing a large article, and of reducing warpage by printing directly on the film. The printed article adheres to the film better than to traditional printer surfaces (glass, metal, glue, or reusable films), because the printed article and film weld together by forming chain entanglements, due to being compatible, miscible, or semi-miscible in the melt.

  • Patent number: 11890800
    Abstract: A method of manufacturing a semi-crystalline article from at least one pseudo-amorphous polymer including a poly aryl ether ketone, such as PEKK, including a softening step, wherein the at least one pseudo-amorphous polymer is heated to a temperature above its glass transition temperature to soften the polymer, and a crystallization step, wherein the at least one pseudo-amorphous polymer is heated to a temperature between its glass transition temperature and melting temperature, the pseudo-amorphous polymer being placed on a mold during either the softening step or the crystallization step before at least some crystallization takes place. The method results in articles demonstrating increased opacity, increased crystallinity, increased thermal resistance, improved chemical resistance, and improved mechanical properties over articles formed by traditional thermoforming processes.
