Estimating the term…
The invention provides a method for producing a 3D item by means of fused deposition modelling, the method comprising a 3D printing stage comprising layer-wise depositing 3D printable material, to provide the 3D item comprising 3D printed material, wherein the 3D item comprises layers of 3D printed material, wherein the 3D printable material comprises thermoplastic material, wherein during at least part of the 3D printing stage the 3D printable material further comprises porous inorganic particles embedded in the thermoplastic material, wherein the porosity of the inorganic particles is in the range 5-60 vol. %, and wherein the inorganic particles (410) have an open porosity. The invention also comprises the product resulting from above method.
A filament for producing a 3D item by means of fused deposition modelling, the filament comprising 3D printable material, wherein the 3D printable material comprises components, wherein the components at least comprise (i) thermoplastic material and (ii) porous inorganic particles;
A 3D item comprising 3D printed material, wherein the 3D item comprises a plurality of layers of 3D printed material, wherein the 3D printed material comprises thermoplastic material, wherein at least part of the 3D printed material further comprises porous inorganic particles embedded in the thermoplastic material, wherein the porosity of the inorganic particles is in the range of 5 to 60 vol. %, and wherein the inorganic particles have an open porosity.
