Abstract

A quick release print head includes a heating block, a nozzle tube and a connecting tube. The nozzle tube is inserted in the heating block. One end of the nozzle tube has a nozzle and the other end is extended with an extension tube exposed to the heating block. The connecting tube is connected with the extension tube. Whereby, the extension tube extended from the nozzle tune is exposed to the heating block so that the nozzle tube disposed near the heating block cannot be disassembled. Thus a process of replacing components by heating a nozzle can be bypassed, and advantages of quick disassembly and easy maintenance of the print head can be achieved.

Abstract

A method for searching plane area on a 3D model comprises following steps of: obtaining an outline of the 3D model; setting a lowest point of the outline based on a datum axis to be a locate point; extending from the locate point along another two axes to search all coordinate points within the outline at a substantially height on the datum axis with the locate point; reserving of the information of the continual coordinate points which can constitute a plane area; recording the plane area; amending value on the datum axis to add fixed variable of the locate point; executing above steps repeatedly until the locate point is amended to be the highest point of the outline based on datum axis.

Abstract

A method for controlling a three-dimensional printing apparatus and a three-dimensional printing system are provided. The method is applicable to controlling a tank of the three-dimensional printing apparatus and includes the following steps. A plurality of layer objects of a three-dimensional object are obtained according to a three-dimensional model, and the layer objects include a first layer object. A structural friability level of the first layer object is obtained according to cross-section information and a printing sequence of the first layer object. A swing velocity of the tank is determined according to the structural friability level. The tank is controlled to swing according to the swing velocity corresponding to the first layer object, such that the cured first layer object is separated from a bottom of the tank.
