Abstract
The present invention is a method for obtaining a ceramic slurry for the production of filaments for 3D FDM printing, comprising adding a polysaccharide, a glycol or an ethanolamine as a gelling agent to a suspension of ceramic material in order to produce said ceramic slurry. The invention also comprises the green body obtained from said slurry and the ceramic filament extruded from the green body.
Claims9
A method for obtaining a ceramic slurry for producing a green body and/or a filament for 3D FDM printing, wherein the method comprises the steps of:
- a) preparing a suspension of a ceramic material in at least one alcohol and/or one C1-C8 ketone chain;
- b) adding a polysaccharide, a glycol or an ethanolamine as a gelling agent;
- c) adding a vinyl resin or polyalkyl carbonate as a binder;
- d) adding a phthalate, terpineol, poly:olefin, thermoplastic or mixtures thereof as a plasticizing agent;
- and
- e) heating at a temperature between 60-150° C.
- to obtain said ceramic slurry;
- wherein
- the ratio of said gelling agent with respect to the ceramic material is between 1:4 and 1:20 by weight;
- the ratio of said binder with respect to the ceramic material is between 1:3 and 1:20 by weight;
- and
- the ratio of said plasticizing agent with respect to the ceramic material is between 1:5 and 1:10 by weight.
