Novel 3D printer and printing process control method thereof

Abstract

The invention discloses a novel 3D printer and a printing process control method thereof. The novel 3D printer comprises a printer body which comprises a cabinet, a first support and a second support, wherein the first support and the second support are arranged on the two sides of the cabinet; a laser scanning device is arranged on the bottom face of the cabinet, a reflector is arranged in the center of the bottom face of the cabinet, and a resin groove is formed over the reflector; high-transmitting quartz glass is fixedly arranged on the bottom face of the resin groove and fixedly arranged on an iron plate, a lifting table is arranged over the resin groove, and the iron plate is connected with a first lifting device; and the lifting table is connected with a second lifting device which is arranged on the first support, and a resin extrusion mechanism is arranged on the second support. As the first lifting device, the second lifting device and the resin extrusion mechanism are in linkage, the control process is simplified according to the 3D printer and the printing process control method of the 3D printer; and in addition, accurate control over the resin flake thickness of the section profile of a product is facilitated.

Description

Technical field: [0001] The present invention relates to the technical field of 3D printers, in particular, to a novel 3D printer and a printing process control method thereof. Background technique: [0002] Using a printer is like printing a letter: Tap the "Print" button on a computer screen, and a digital document is sent to an inkjet printer, which sprays a layer of ink onto the surface of the paper to create a second copy. dimensional image. With 3D printing, software completes a series of digital slices through computer-aided design (CAD) and sends information about those slices to a 3D printer, which stacks successive thin layers until a solid object is formed. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. [0003] There are various forms of stacking thin layers. Some 3D printers use an "inkjet" method. For example, an Israeli 3D printer company called Objet uses a printer nozzle to spray an...

Problems solved by technology

However, photocuring rapid prototyping technology also has two shortcomings. First, the raw material of photosensitive resin has certain toxicity, and the operator needs to pay attention to protection when using it. Secondly, the prototype of photocuring molding is very good in appearance, but its strength cannot be compared with real finished products. In comparison, it is generally used for prototype design verification, and then transforms the rapid prototype into an industrial-grade product through a series of subsequent processing procedures

In addition, the equipment cost, maintenance cost and material cost of SLA technology are relatively high. Therefore, 3D printers based on light curing technology are mainly used in the professional field, and there is no application in the domestic desktop field.
