Rotary-type 3D (three-dimensional) printer

Abstract

The invention discloses a rotary-type 3D (three-dimensional) printer, and belongs to the fused deposition quick molding equipment. The rotary-type 3D printer comprises a base, a printing head platform drive mechanism and a printing head, wherein an objective table is arranged on the base, the printing head platform drive mechanism is arranged on the base, and the printing head is arranged on the printing head platform drive mechanism. The printing head platform drive mechanism comprises a linear motor base, a linear motor, a rotary motor base, a rotary motor, a rotary arm and a printing head platform horizontal moving motor, wherein the linear motor is fixed on the base and arranged at one side, towards the rotary arm, of the linear motor base, the rotary motor base is fixed on the linear motor, the rotary motor is fixed on the rotary motor base, a rotary motor shaft is fixed with one end, towards the linear motor, of the rotary arm, the other end of the rotary arm is corresponding to a position above the objective table, the printing head platform horizontal moving motor is arranged at one side, towards the objective table, of the rotary arm, and the printing head is fixed on the printing head platform horizontal moving motor. The rotary type 3D printer disclosed by the invention can be used for improving the printing speed, printing high-precision components and precisely controlling the radius, the angle and the height, and is high in space utilization rate.

Description

[0001] This application is a divisional application of an invention patent application named: rotary 3D printer, application date: November 21, 2014, and application number: 201410674487.1. technical field [0002] The invention belongs to the technical field of fusion deposition rapid prototyping equipment, and in particular relates to a rotary 3D printer. Background technique [0003] Because 3D printing integrates cutting-edge technical knowledge in digital modeling technology, electromechanical control technology, information technology, material science and chemistry, etc., it makes large-scale personalized production possible and leads a major change in the global manufacturing economy. widely received people's attention. 3D printer is the core equipment of 3D printing. It uses consumables (consumables such as: powdered metal materials, plastics, ceramics, sand and other bondable materials) based on digital model files to build objects by layer-by-layer printing.

Problems solved by technology

Another example is that the authorized announcement number CN203485190U provides "a 3D printer based on a parallel mechanism". Because the patented solution uses a servo motor (paragraph 0016 of the specification), it is not only large in size, but also reliable in controlling the spatial position of the printing nozzle. Low

Furthermore, as the invention patent application publication number CN103862679A introduces a "3D printer", the patent application evaluates the aforementioned CN103317726A in paragraph 0004 of its description, and the technical solution it provides (paragraphs 0006 to 0012 of the description) overcomes the disadvantages of CN103317726A. However, because the patent application scheme uses a stepping motor to drive the print head to move, the control accuracy of the print head and the speed at which the print head is driven are difficult to achieve the desired effect in the industry
