Abstract
Official abstract text for this publication.
The present invention relates to the technical field of 3D printing, especially in the form of the binder jetting method, in which particles in a powder bed are bonded by means of a printed adhesive to form a three-dimensional object. The particles may be inorganic particles, for example sand or a metal powder, or polymeric particulate, for example polymethacrylates or polyamides. For this purpose, polymethacrylates may take the form, for example, of suspension polymers, called bead polymers.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing three-dimensional objects from a powder bed by means of a binder jetting method by multiple repetition of the method steps of: a) applying a powder layer on a surface, wherein the powder bed includes at least two different kinds of particulate material, the first particulate material having a median diameter between 10 and 500 μm, and the second particulate material comprising coagulated emulsion polymers having a median secondary…
