The present invention relates to a method for producing a coated object by additive manufacturing in vacuum and to a device for producing a coated object. The method comprises forming a first polymer layer on a workpiece and/or on a printing bed. A first coating layer is formed on at least a part of the first polymer layer by vacuum-based vapor deposition. A second polymer layer is formed on at least a part of the first polymer layer and/or of the first coating layer, wherein the second polymer layer is formed before, during or after forming the first coating layer. The first polymer layer, the first coating layer and the second polymer layer are formed in vacuum at a gas pressure of less than 10.sup.2 mbar.

In one aspect, a method is described. The method may include ionizing a plasma gas to generate a plasma in a plasma source and accelerating the plasma toward a work surface. The method may further include adding a material to the plasma, thereby melting the material and accelerating the melted material toward the work surface. The method may further include depositing successive layers of the melted material on the work surface to form a three-dimensional object. Each of the successive layers may correspond to one of a number of planar slices of the three-dimensional object.

A solution-based system for printing a 3D structure is provided and includes a substrate; a first solution including an organic molecule including a functional group at each end for creation of self-assembled monolayers (SAMs) including a first self-assembled monolayer (SAM) as a building block for printing the 3D structure, wherein the first solution is applied to a surface of the substrate to form the first SAM including a first SAM surface as a basis for the 3D structure; a second solution including metal ions, wherein the substrate with the first SAM is immersed into the second solution, and wherein the first solution is applied to the substrate which is immersed in the second solution thereby obtaining molecular-metal SAMs to provide a multiple layered SAM material; and means for applying a force and forming the 3D structure from the multiple layered SAM material, wherein the 3D structure is provided on the substrate.

Presented are systems and methods that provide conformal design and motion planning that wraps a two-dimensional pattern onto a three-dimensional surface. Such systems and methods utilize a parameterization of the 3D surface in two dimensions, preferably using non-uniform rational B-splines (NURBS). Such systems and methods then provide an optimization of the parameterized surface to minimize distortion, preferably by maintaining point-to-point distances along the parametric coordinates, but with a generalizable approach to support custom constraints. Interpolation of 2D toolpath coordinates or other 2D patterns on this distorted mesh is then performed. Once complete, the parametric pattern values are remapped to 3D space using the parametric surface definition.
