Abstract
An apparatus for layerwise manufacturing of a three-dimensional object by solidification of a material, which can be solidified via electromagnetic radiation, includes a source for the electromagnetic radiation, a building space for manufacturing the three-dimensional object, a coupling window, for transmitting the electromagnetic radiation into the building space and a heating element for heating the coupling window. By the heating element the temperature of the lens is increased during the building of the three-dimensional object. By the increased temperature the accumulation of contamination on the coupling window is prevented.

Apparatus configured to perform layerwise manufacturing of a three-dimensional object by solidification of a building material capable of being solidified by electromagnetic radiation, said apparatus comprising:
- a source of said electromagnetic radiation,
- a building space for manufacturing said three-dimensional object,
- a coupling window adapted to allow for transmitting said electromagnetic radiation into said building space,
- a heating element that heats said coupling window to a temperature sufficient to reduce accumulation on the coupling window of contamination that is generated by action of said electromagnetic radiation on said building material, and
- wherein said coupling window is heated by said heating element during said transmitting of said electromagnetic radiation through said coupling window.
A method for layerwise manufacturing of a three-dimensional object by solidification of a building material capable of being solidified by electromagnetic radiation, comprising the steps of
- providing a building space serving for the manufacturing of said three-dimensional object,
- providing a source for emitting said electromagnetic radiation,
- providing a coupling window through which said electromagnetic radiation is transmitted into said building space, and
- heating said coupling window using a heating element, while transmitting of said electromagnetic radiation through said coupling window for layerwise manufacturing of said three-dimensional object to a temperature sufficient to reduce accumulation on the coupling window of contamination that is generated by action of said electromagnetic radiation on said building material.
