Abstract

The instant invention relates to a method for changing characteristics of a plastic component, wherein a medium is introduced into the plastic component, which encompasses a porosity and wherein the medium forms a homogenous compound with the plastic component by at least partially dissolving the plastic component.

Claims

1. A device for manufacturing patterns in layers, encompassing a vertically displaceable build platform, a dispensing device for applying binder material onto the build platform, wherein the device additionally encompasses a mounting platform, to which all displacement units for the dispensing device and for the build platform are affixed.

2. The device according to claim 1, wherein a spreader device for applying fluid is provided.

3. The device according to claim 2, wherein all displacement units of the spreader device are further affixed to the mounting platform.

4. The device according to claim 1, wherein the dispensing device the spreader device, or both are further affixed to the mounting plate.
