A method for preventing detachment of a three-dimensional object from a printing tray of a printing apparatus is disclosed. The method includes printing a carpet of building material below and around the base of a three-dimensional object to be printed; and printing said three-dimensional object. The portions of the carpet that protrude out of the boundaries of the base of the three-dimensional object are coated with one or more layers of support material to help keep the carpet flexible and adhesive in texture.

The present disclosure relates to a build material for 3D printing. The build material comprises polymeric particles comprising polypropylene and at least one elastomer. The polymeric particles comprise a surface-active coating.

A method for producing a support structure of a 3D model for 3D printing is provided. A method for producing a support according to an embodiment of the present invention comprises the steps of: dividing a surface constituting a 3D model into multiple surface patches; classifying respective divided surface patches according to geometric characteristics; and producing supports corresponding to the classified characteristics with regard to respective surface patches. Accordingly, during metal laminate manufacturing, the output stability may be improved while reducing the support producing process time. In addition, the surfaces may be expressed by different colors according to the result of geometric characteristic classification, and the supports may also be expressed by different colors according to the type, thereby playing the role of guide lines such that the user can recognize the shape of the surfaces and the type of supports to be installed on the corresponding surfaces. Moreover, the size of a support tip is determined in view of the thickness of the area in which a support is to be produced, thereby preventing the problem of output quality degradation which would otherwise occur because the support cannot move upwards through an output part.
