<p>The invention relates to methods and devices for producing miniature bodies or microstructured bodies on a support in a processing chamber in a vacuum or protective gas atmosphere, using laser beams of at least one laser that is placed inside or outside said chamber, whereby the laser beams are guided over the surface of the support that is provided with particles. The miniature bodies and the microstructured bodies are formed from particles that are applied in layers. Spacer bodies, which are likewise configured from particles that are applied in layers, are situated between the support and the miniature bodies. Said spacer bodies are produced by irradiation by the laser beams in such a way that particles are sintered in a partially planar, planar or linear manner on the corresponding plane to form small spacer bodies that have contact area structures and voids and can thus be destroyed and subsequently removed from the support and the miniature bodies or microstructured bodies. Spacer bodies are simultaneously formed with a static stability, allowing a secure positioning of the miniature bodies or microstructured bodies in relation to one another on the support and/or in the powder bed.</p> |
