There are those processes for rapid prototyping

rapid prototyping technology is integrated and developed on the basis of modern CAD/CAM technology, laser technology, computer numerical control technology, precision servo drive technology and new material technology up. Different types of rapid prototyping systems have different forming principles and system features due to different forming materials used. But the basic principles are the same, that is'Layered manufacturing, layer by layer', Similar to the integral process in mathematics. In an image, the rapid prototyping system is like a'Stereo printer'.

Rapid prototyping method:

SLA: the selective curing of light-sensitive resin with relatively slow molding speed is made of stereo engraving ( Stereolitography) The short name of a process of principle is a rapid prototyping technology that appeared earlier. Filled with liquid photosensitive resin in the resin tank, it will quickly cure under the irradiation of ultraviolet laser beam. At the beginning of the molding process, the lifting table is at the height of the layer thickness of the next section of the liquid level. The focused laser beam, under the control of the computer, scans along the liquid level according to the requirements of the section profile, the resin in the scanned area is cured, so that the resin sheet of the profile of this section is obtained.

SLA-related samples

SLS :( Sleeping laser sintering) Selective sintering of powder materials is a rapid prototype process, which is referred to as selective sintering of powder materials. Carbon dioxide laser is used for powder materials (Mixed powder with adhesive such as plastic powder) Selective sintering is a rapid prototyping method that integrates three-dimensional entities layer by layer from discrete points. Selective sintering of powder materials using carbon dioxide lasers for powder materials ( Plastic powder, mixed powder of ceramic and binder, mixed powder of metal and binder, etc) Selective sintering is a process method that integrates three-dimensional entities layer by layer from discrete points. Before starting processing, heat up the studio filled with nitrogen and keep it below the melting point of the powder.

CNC machining: the CNC prototype model mainly uses CNC machine tools. CNC machine tool as a modern industry is inseparable from the mechanical and electrical automation production equipment, is the general trend of the industry, the next decade, the traditional machine tool will be gradually eliminated. Therefore, the CNC prototype model industry driven by numerical control technology will not have poor natural prospects. Although the traditional prototyping is still very popular, with the strength of industrial parts production in the future, the design of parts is more exquisite and complicated, and it is difficult for artificial prototypes to adapt to this situation, there is no doubt about the demand for CNC prototypes.

vacuum compound mold: using the product (Such as: fast prototype, prototype, prototype)The prototype is made into a silicone mold in a vacuum state. At present, silicone molds are widely used in model making. And use the mold in a vacuum state (PU, transparent PU, Sai steel, ABS) Other materials can be poured into the same copy as the product prototype and can reach the hardness and strength of ABS and other materials, which can be copied together according to the customer's needs. Due to the fast speed and low cost, greatly reduce the cost, time and risk of product development. It can meet the requirements of performance testing, market, inspection and approval in the process of product development. Greatly improve the market competition of customers.
