A drone printer configured to print an image on a destination surface includes a flying management module (FMM) and a printing system (PS). The FMM comprises a positioning system configured to detect position of the drone printer in 3-Dimensional (3D) space, and generate a rendering flight plan (RFP) in the 3D space, said RFP being representative of routing path that the drone printer is to follow during printing of the image on the destination surface; and a stabilizer system configured to stabilize the drone printer in the 3D space during any or a combination of flying, aerial manoeuvring, and homing. The PS can include at least one colorant tank; and at least one printing device configured to draw colorant from the at least one colorant tank, and apply the colorant on the destination surface so as to print the image along at least a part of the RFP.

A computer projector system and method for customization (labelling) of apparel and merchandise. The computer projector system provides virtual customer-assisted layout of apparel and merchandise targeted towards customization of branded sports merchandise which is manually assembled or pressed. The computer projector system consists of a mechanical arm attached to a heat press, a mini projector, a computer and cloud-based software with a database of customization of embellishments. The computer projector system displays an image of the customized set of numbers, letters, or patch design directly on the apparel (or other merchandise), so that the operator can manually place and press the components in a highly efficient and accurate manner. The computer projector system also addresses the problem of automatically correcting for kerning and arcing on customized product in accordance with pre-determined guidelines in the sports and entertainment industries.

To provide an image display device configured to more faithfully display a projection image on a region where a physical quantity change has occurred. An image display device of the present invention includes a flow rate sensor and a screen on which an image from a projector is projected, and a control is performed such that the image is projected on the screen so as to include a position of the flow rate sensor that has detected the physical quantity change, and the image changes corresponding to a measured value change of the flow rate sensor. Preferably, a plurality of the physical quantity detection units are disposed, and the control is performed such that the image changes corresponding to the measured value changes in the respective physical quantity detection units.

A digital light processing (DLP) three-dimensional (3D) printing system includes a container containing a solidifiable material; a platform contacting a portion of the solidifiable material; a projector projecting an electromagnetic radiation on the solidifiable material to form a solidified layer; and an optical component between the projector and the platform; wherein the optical component is rotated to shift the electromagnetic radiation during the formation the solidified layer, thus forming a rounded edge and an enlarged area of the solidified layer. A digital light processing (DLP) three-dimensional (3D) printing method is also disclosed.

The disclosure provides a three-dimensional (3D) printing device including a tank, a forming stage and an irradiation unit. The tank is filled with a liquid forming material. The forming stage is movably disposed at the tank. The irradiation unit is disposed beside the tank and includes an image source and a projecting lens. The image source is used to emit an image beam. The image beam passes through the projecting lens to irradiate and cure the liquid forming material. An entrance pupil position of the projecting lens is ENP and 2000 mmENP15000 mm. An exit pupil position of the projecting lens is EXP and 2000 mm|EXP|15000 mm.
