The invention relates to a method for producing an at least partially coated object, comprising the step of producing the object from a construction material by means of an additive manufacturing method, the construction material comprising a thermoplastic polyurethane material. Following the production of the object, the method comprises the step of at least partially bringing a preparation into contact with the object, the preparation being selected from: an aqueous polyurethane dispersion; an aqueous dispersion of a polymer comprising OH groups, this dispersion also containing a compound comprising NCO groups; an aqueous preparation of a compound containing NCO groups, but not containing any polymers comprising OH groups; or a combination of at least two thereof. The invention also relates to an at least partially coated object that was obtained by a method according to the invention.

Method for producing an at least partially coated object

It is a feature of a porous body () comprising a three-dimensional network of node points () joined to one another by struts (), and a void volume () present between the struts (), that the struts () have an average length of ≥200 to ≤50 mm, the struts () have an average thickness of ≥100 μm to ≤5 mm, and that the porous body has a compression hardness (40% compression, DIN EN ISO 3386-1: 2010-09) in at least one spatial direction of ≥10 to ≤100 kPa. The porous body according to the invention combines the advantages of a conventional mattress or cushion with ventilatability which results from its porous structure and is not achievable in conventional foams. The invention further relates to a method of producing such a porous body () and to an apparatus comprising said body () for supporting and/or bearing a person.
