  • Patent number: 10793731
    Abstract: The present invention relates to the technical field of 3D printing, in particular in the form of the binder jetting process in which particles in a powder bed are adhesive-bonded by means of a printed adhesive to give a three-dimensional object. The particles here can be inorganic materials, e.g. sand or a metal powder, or polymeric particles, such as polymethacrylates or polyamides. To this end, polymethacrylates can by way of example take the form of suspension polymers known as bead polymers. In this context the present invention in particular relates to, as powders for 3D printing, suspension polymers which differ from the prior art in that they comprise a hard phase and an uncrosslinked soft phase.

  • Patent number: 10688718
    Abstract: The present invention relates to the technical field of 3D printing, especially in the form of the binder jetting method, in which particulate material in a powder bed is bonded by means of a printed adhesive to form a three-dimensional object. The particulate materials may be inorganic materials, for example sand or a metal powder, or particulate polymeric materials, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers. The present invention relates to the use of porous particles in the binder jetting process, in particular of porous suspension polymers. These powders for 3-D printing differ from the prior art in that the porosity results in a faster and better absorption of the printed binder by the powder particles. A great advantage of this procedure is additionally that a product with less warpage is formed and that the end product has a better surface appearance.

  • Publication number: 20200017622
    Abstract: A polymeric particle has an average diameter from 300 nm to 1000 nm and includes an outer layer, containing a cross-linked polymer A, and a first inner layer, containing a cross-linked polymer B, distinct from the cross-linked polymer A. The cross-linked polymer A is obtainable by emulsion polymerisation of a reaction mixture including at least one (meth)acrylic monomer, a cross-linking monomer A, a polymerisation initiator and a chain transfer agent.

  • Publication number: 20170361531
    Abstract: A three-dimensional object is formed by 3D printing, especially by a binder jetting method, in which particulate material in a powder bed is bonded by a printed adhesive. The particulate materials may be inorganic materials, for example sand or a metal powder, or particulate polymeric materials, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers. Powder bed compositions comprising core-(shell)-shell particles can be used for 3D printing, wherein the core-(shell)-shell particles can swell in contact with the binder during the printing operation.

  • Patent number: 7374743
    Abstract: Mixed oxide powder containing indium and tin, with a proportion of indium oxide of between 90 and 98 wt. % and a BET surface area of 40 to 120 m2/g, which is in the form of aggregates having an average circumference of less than 500 nm, consists of at least 95% of an indium oxide phase and displays an oxygen content that is lower than the content that theoretically results from In2O3 and SnO2. It is produced by mixing a solution of an indium compound with a solution of a tin compound, atomising this mixture of solutions, pyrolysing the atomised mixture of solutions in a first zone of a reactor and in a second zone of the reactor, following pyrolysis, adding reducing gases to the pyrolysed mixture at one or more points in a quantity such that overall a reducing atmosphere is established in this second zone, and separating the resulting solid from the waste gases in a further, third zone, in which a reducing atmosphere likewise still prevails.
