  • Method and apparatus for 3D-printing gels
    Patent number: 11117314
    Abstract: Methods and apparatuses (400) suitable for use in 3D-printing of gels from a solution (470) comprising a polymerizable material dispersed in a solvent are described. Such methods and apparatuses (100) include features (493) to control the relative saturation of the solvent in a gas phase region around the gel during the 3D-printing process.

  • METHOD OF MAKING POLYMER ARTICLES AND POLYMER COMPOSITES BY ADDITIVE PROCESSING AND POLYMER AND COMPOSITE ARTICLES
    Publication number: 20200131385
    Abstract: Provided is a method of producing polymer articles comprising (i) subjecting a composition to additive processing in an additive processing device containing at least one energy source wherein the composition comprises particles of a first polymer, particles of a second polymer and at least one binder material capable of binding the polymer particles to form a layer in a part of the composition that has been exposed to the energy source of the additive processing device; (ii) subjecting at least a part of the composition to exposure of the energy source to form a layer comprising the polymer particles and binder material; (iii) repeat step (ii) to form a plurality of layers to create an article; and wherein the first polymer is selected from polymers having a melting point above of at least 250° C. or a glass transition temperature (Tg) of greater than 70° C. and is not a fluoropolymer and wherein the second polymer is a fluoropolymer.
