Patent Images
1. A device for producing three-dimensional models by a layering technique comprising:
- at least one print head being provided for selective dispensing of at least one material onto a target surface in the form of droplets,wherein the print head is in engagement with a receptacle at two points spaced a distance apart, wherein the receptacle includes one or more adjustment elements at each of the two points, wherein the adjustment elements are sufficiently adjustable so that the position and alignment of the print head in relation to the target surface is steplessly adjustable in all spatial directions via the adjustment elements at these two points,wherein the print head includes one or more rows of nozzles, wherein the one or more rows are aligned perpendicular to an x-direction of printing, andwherein the receptacle and the target surface are movable in relation to each other.

25. A method for producing three-dimensional models by a layering technique comprising the steps of:
-
depositing a particulate material onto a target surface; and selectively dispensing at least one material in the form of droplets from at least one print head onto the target surface; wherein the print head is in engagement with a receptacle at two points spaced a distance apart, wherein the receptacle includes one or more adjustment elements at each of the two points, wherein the adjustment elements are sufficiently adjustable so that the position and alignment of the print head in relation to the target surface is steplessly adjustable in all spatial directions via the adjustment elements at these two points, wherein the print head includes one or more rows of nozzles, wherein the one or more rows are aligned perpendicular to an x-direction of printing, and wherein the step of selectively dispensing includes a step of moving the receptacle over the target surface in the x-direction of printing. - View Dependent Claims (26)
