The invention discloses a method for producing a three dimensional molded product from cellulose fibers, comprising the steps of: providing a cellulose fiber composition comprising 1-30 wt % lignin, said cellulose fiber composition further having a solid content between 0.1-95%; providing a forming tool having a three dimensional shape including a forming surface, and bringing said forming surface into contact with the cellulose fiber composition; and press drying the cellulose fiber composition contacted by the forming tool at temperatures>200° C. to a dry content of at least 70%. The invention also relates to a three dimensional fiber based product obtainable by means of said method.
