3D-PRINTED SHEET MATERIAL Russian patent published in 2023 - IPC B29C51/02 B29C51/08 B29C51/10 C08L1/02 D21H11/14 

FIELD: 3D-printing.

SUBSTANCE: invention relates to a 3D-printed sheet material, a method for manufacturing a 3D-printed product, as well as a 3D-printed product, including a corresponding 3D-printed sheet material. The 3D-printed sheet material contains a cellulosic material in the amount of 5 to 55 wt.%, and a particulate inorganic filler material in the amount of ≥45 wt.%, based on the total dry weight of the 3D-printed sheet material. Moreover, the cellulose material is a mixture based on cellulose material containing nanofibrillated and/or microfibrillated cellulose in the amount of ≥55 wt.% and cellulose fibres in the amount of ≤45 wt.%, based on the total dry weight of the mixture based on the cellulosic material.

EFFECT: 3D-printed sheet material with sufficient strength, improved extensibility, uniformly distributed mass and less prone to delamination.
