Abstract
A device for manufacturing microstructures including a permeable template, wherein the template comprises at least one recess for manufacturing the microstructures. In addition, the device comprises a vacuum-generating device connected to the template such that a vacuum is applied to at least one side of the template. Further, a method for filling a permeable template, wherein the template comprises at least one recess for manufacturing microstructures. The method comprises feeding the at least one substance to be filled in to the template as well as generating a vacuum on at least one side of the template
Claims20
A device for manufacturing microstructures, in particular microneedles, comprising:
- at least one permeable gas-transmissible template,
- wherein the at least one template comprises at least one conical recess for manufacturing the microstructures,
- wherein at least one device is connected to the at least one template for generating a vacuum such that a vacuum is applied to at least one side of the at least one template, in particular at least opposite the at least one recess of the at least one template.
A method for filling a permeable, in particular gas-transmissible template, wherein the template includes at least one recess for manufacturing microstructures, comprising the step of:
- feeding at least one preferably liquid substance to be filled in to the template;
- and
- generating a vacuum on at least one side of the template in particular at least opposite the at least one recess of the template, wherein the step of generating the vacuum is performed before, after and/or during the step of feeding the substance to the template.
