Abstract
A microfluidic print head of a printer has a distal face, an injection channel, a suction channel, a groove, and a light source or an optical waveguide. The injection channel is configured to inject an ink onto a substrate and leads onto the distal face by an injection opening The suction channel is configured to suck up the ink and leads onto the distal face by a suction opening. The groove is defined on the distal face and into which the suction opening leads.
Claims20
A microfluidic print head of a printer, the microfluidic print head comprising:
- a distal face;
- at least one injection channel configured to inject an ink onto a substrate, the injection channel leading onto the distal face through an injection opening;
- at least one suction channel configured to suction up the ink, the suction channel leading onto the distal face through a suction opening;
- a groove defined on the distal face where the suction opening leads;
- and
- at least one light source or optical waveguide,
- wherein the at least one light source or optical waveguide is configured to project a beam of light onto a lighting zone located on the distal face, the lighting zone being configured to project the beam of light from the distal face.
