Abstract

The invention relates to a device and to a method for the production of a three-dimensional object by the consecutive layered bonding of a material that can be bonded by means of electromagnetic radiation, wherein in the so-called vat an at least n-phase system, where n>2, is present, of which at least one phase comprises the building material and at least one other a phase that cannot be mixed with the building material.

Claims

1. An apparatus for the production of a three-dimensional object by the consecutive layered solidification of a material that can be solidified by electromagnetic radiation, wherein in a vat holds an at least n-phase system with n≧

2 of which at least one phase comprises the process material and at least one other a phase that cannot be mixed with the process material.

2. The apparatus defined in claim 1, further comprising pump means for varying the layer thickness of at least one of the phases during the consumption of the phase that contains the process material.

3. The apparatus defined in claim 1, further comprising:

pump means for varying the layer thickness of at least one of the phases can be during the consumption of the phase that contains the process material; and

an active or passive system for coating.

4. The apparatus defined in claim 1, further comprising:

pump means for varying the layer thickness of at least one of the phases during the consumption of the phase that contains the process material and further,

an active or passive system for coating, the auxiliary phase being transparent to electromagnetic radiation in the spectral range of the absorption spectrum of the photo initiator, and

a radiation source suitable for the finish curing of the generated object irradiates the auxiliary phase.
