Abstract
The present invention relates to a method for additive manufacturing of a 3D-structured form and to a device for additive manufacturing of a 3D-structured form.
Claims14
A method for additive manufacturing of a 3D-structured form, the method comprising the steps of:
- i) providing a liquid photoresist comprising at least one monomer and at least one photoinitiator system;
- and
- ii) irradiating the liquid photoresist with a first light source at a first wavelength λ1 and with a second light source at a second wavelength A2 to harden the liquid photoresist and produce the 3D-structured form,
- wherein λ1≠λ2, and
- wherein the hardening of the liquid photoresist to produce the 3D-structured form takes place only at the position which is irradiated by the first light source and the second light source with a time interval of less than 1 ms.

A device for additive manufacturing of a 3D-structured form, starting from a liquid photoresist, the device comprising:
- a first light source with a first wavelength λ1;
- a second light source with a second wavelength λ2;
- and
- a substrate is configured for providing the liquid photoresist,
- wherein λ1≠λ2, and
- wherein the first light source and the second light source are configured to be oriented toward the substrate in order to harden the liquid photoresist at the position which is irradiated by the first light source and the second light source with a time interval of less than 1 ms.
