Element comprising a non-stick surface and method for three-dimensional printing such an element

A method for producing an element comprising a non-stick surface for substantially cleanly removing a product which is arranged against said non-stick surface using a three-dimensional printer, wherein the method comprises the steps of:

• providing a layer of granular material,
• performing a printing process to form a printed layer by directing a laser beam at printing positions on or in said layer of granular material using a first set of printer settings or a second set of printer settings of said three-dimensional printer,
• changing a set of printer settings of the printing process from the first set of printer settings to the second set of printer settings, or vice versa, during the forming of said printed layer,
• wherein the first set of printer settings are configured such that during said printing process, particles of said granular material are partially fused together to form a material wherein a space between the particles is at least partially maintained to form the pervious part, such that a space between the particles in the pervious part is at least partially interconnected to allow a fluid to flow through the pervious part,
• wherein the second set of printer settings are configured such that during said printing process, particles of said granular material are fused together to form a material wherein a space between the particles of the granular material is substantially removed to form the impervious part, and
• wherein an outer surface of the pervious part provides the non-stick surface.
