The invention provides an energy efficient method to manufacture 3D shaped articles， with smooth crease-free surfaces， from cellulose-based material. The method comprises the steps of: - providing a suspension with a dry content of more than 10%， which suspension comprises at least 95w% of cellulose fibers calculated on the total amount of dry material， whereof at least 50w% of said cellulose fibers have a fiber length of less than 1 mm， - spraying said suspension on a 3D-shaped， heated mold having a smooth surface， in at least a first step， whereby a 3D shaped article of cellulose fiber based material is formed， - drying said 3D shaped article.
