Abstract: A 3D printing apparatus includes a substrate stage configured to support a substrate, a droplet ejector including at least one droplet nozzle configured to discharge a photo-curable droplet on the substrate, a first photo curing unit configured to irradiate light to a drop path along which the droplet discharged from the droplet nozzle falls to change a viscosity of the droplet, and a second photo curing unit configured to irradiate light onto the droplet that has landed on the substrate to cure the droplet.

Abstract: A die alignment method includes vertically aligning a first die comprising first magnetic patterns and a second die comprising second magnetic patterns with each other using magnetic force between the first magnetic patterns and the second magnetic patterns. Each of the first magnetic patterns and the second magnetic patterns comprises a horizontally magnetically anisotropic material. The first magnetic patterns and the second magnetic patterns do not vertically overlap each other when the first die and the second die are vertically aligned with each other.

Abstract: An inkjet printing method includes: setting a first region to be printed at a constant print density within a target region to be printed; setting a second region within the target region and closer than the first region to an edge of the target region, wherein the second region is to be printed at a print density that varies according to a position; generating control data for a plurality of nozzles provided on an inkjet head in order to print the first region and the second region; and driving the inkjet head according to the control data.
