Three-dimensional printing apparatus

Abstract

A three-dimensional (3-D) printing apparatus includes a base, a printing head module and a control unit. The base includes a carrying surface and a guiding mechanism. The guiding mechanism extends along a long-axis direction of the base. The printing head module movably disposed on the guiding mechanism. The length of the base is greater than the length of the printing head module, such that the printing head module is suitable for moving relatively to the guiding mechanism. The control unit coupled to the base and the printing head module controls the printing head module to move relatively to the base according to extensional information of the digital 3-D model along the long-axis direction, such that the printing head module dispenses a material on the carrying surface to form a 3-D object when moving relatively to the base.

Description

technical field [0001] The present invention relates to a printing device, and in particular to a three-dimensional printing device. Background technique [0002] With the advancement of Computer-Aided Manufacturing (CAM), the manufacturing industry has developed three-dimensional printing technology, which can quickly produce the original design concept. Three-dimensional printing technology is actually a general term for a series of rapid prototyping (RP) technologies. The Z coordinate discontinuously displaces the thickness of the layer, and finally forms a three-dimensional object. Three-dimensional printing technology can have unlimited geometric shapes, and the more complex parts are, the more superior the RP technology is, which can greatly save manpower and processing time. Under the shortest time requirement, 3D computer-aided design (Computer-Aided Design, The digital three-dimensional model designed by CAD) software is truly presented, not only can be touched, b...

Problems solved by technology

[0003] However, the current three-dimensional printing device that uses the above-mentioned rapid prototyping method to form three-dimensional objects is to extrude the substrate through the printing head and form it layer by layer on the base, and then, for example, to obtain the three-dimensional object through steps such as drying and hardening, so , the size of the three-dimensional object printed by the three-dimensional printing device will be limited by the size of the base and cannot print a larger object

Therefore, the current three-dimensional printing device is still very inconvenient to use, and the change and flexibility of the three-dimensional objects printed by it are also limited.
