Abstract
A method for obtaining an object, such as an interior design object or a piece of furniture, includes the steps of producing a base structure of the object, and applying a coating to at least part of the base structure. The step of applying the coating includes distributing, onto the base structure, a material castable in a mold or producing one or more preformed blocks of this castable material in a mold to be joined to the base structure, and subsequently machining the coating using machine tools to generate a final shape.
Claims10
A method for obtaining an object comprising the steps of:
- producing a base structure of the object;
- distributing a first polyurethane material onto at least a part of said base structure so as to create a rigid shell, which confers predetermined structural features to said base structure, said first polyurethane material being a compact rigid polyurethane material;
- providing a coating, which coats at least part of said rigid shell, said step of providing the coating comprising producing one or more preformed blocks made of said second type of polyurethane material and joining said one or more preformed blocks to said base structure, said second type of polyurethane material being an expanded polyurethane material which forms an external layer overlapping said rigid shell, said external layer being produced with an increased thickness;
- and
- subsequently machining, said external layer of expanded polyurethane material using a machine tool so as to bring the object to a final size.
