摘要： The present application discloses a 3D printing device and a release method and a liquid containing mechanism therefor, and relates to the field of 3D printing. The liquid containing mechanism comprises a material box foundation, a material box and a plurality of motion guide components. The material box foundation is a rigid annular plate with a mounting groove and is detachably mounted on a base of the 3D printing device, the mounting groove of the material box foundation is covered by a light-transmitting glass plate, and the glass plate is fixed on an upper surface of the material box foundation. The plurality of motion guide components are fixed to a peripheral edge of the material box and then detachably fixed on the material box foundation. Each of the motion guide components is a following component with an upper limit structure and a lower limit structure, and the following component is fixed to the peripheral edge of the material box. The plurality of motion guide components are configured for enabling the material box to follow a printing mechanism for a certain distance between the upper limit structures and the lower limit structures so as to release a film. By a design of fixed glass plate and a separated and multi-section release, the liquid containing mechanism of the present application features improved printing quality, reduced cost and less likelihood of film deformation.

摘要： A 3D printer includes a resin reservoir arranged for being filled with a predetermined amount of liquid resin, a light exposure module, and a control processor. The light exposure module includes a plurality of light sources supported above the resin reservoir, wherein each of the light sources is arranged for flashing a discrete image to solidify the liquid resin in the resin reservoir. The control processor controls the light sources to flash the discrete images at the same time and to combine the discrete images into a combined image for forming a layer of a 3D object when the liquid resin is solidified.

摘要： A production method of a digitized artificial nail for a nail of a user includes the steps of: (a) scanning the nail of the user to construct an irregular digitized user nail model; (b) data sampling to convert the irregular digitized user nail model into a regular digitized artificial nail model which is a regular three dimensional grid surface, and topology deformation of the regular three dimensional grid surface to form a digitized artificial nail model; (c) matching an artificial nail shape selected by the user with the digitized artificial nail model to obtain a desired artificial nail model; (d) customizing the digitized artificial nail model; and (e) three dimensional printing a digitized artificial nail in response to the digitized artificial nail model.

摘要： A fine-displacement adjusting device is constructed to have a first base portion and a second base portion spacedly encircled therewithin. The fine-displacement adjusting device further includes a first retractable element biased between the first and second base portions, and a first resilient element biased between the first and second base portions. The first retractable element is configured to extend and retract its length along a first axis to move the second base portion in a reciprocating manner. When the second base portion is moved by the first retractable element, the first resilient element moves the second base portion along the first axis to restore the second base portion. Therefore, the second base portion is fine-moved along the first axis in a reciprocating manner for adjusting the fine-displacement of an optical lens relative to an optical light source of a light engine in the first axis.
