Introduction of prototyping technology

- Jun 04, 2018 -

In the product design process, after we completed the design drawings, one of the most wanted things is to know what kind of design things are made of, what the appearance and design ideas are, and whether the design is reasonable or not. ? manufacturing is produced in response to this demand. In general, prototype is one or more of the functional models that can be used to check the appearance or structure rationality based on product appearance drawings or structural drawings without opening the mold.

Hand board classification:

      The early prototype was constrained by various conditions, mainly because most of its work was done by hand, making it difficult to strictly meet the dimensional requirements of the appearance and structural drawings, so its appearance was checked. The function of structural rationality is also greatly reduced.

    With the advancement of science and technology, the rapid development of CAD and CAM technology has provided better technical support for the manufacture of handboards, making the accuracy of handboards possible.

 On the other hand, with the increasingly fierce social competition, the speed of product development has increasingly become a major contradiction in competition, and hand board manufacturing can effectively improve the speed of product development.

 It is in this situation that the prototype manufacturing industry has emerged as a relatively independent industry and has flourished.

 According to the method of production, the hand boards can be divided into manual hand boards, numerical control hand boards and 3D printed hand boards:

 (1) Manual prototype: Its main workload is done by hand.

 (2) CNC prototype: Its main workload is achieved by CNC machine tools. According to the different equipment used, it can be divided into Laser Rapid Prototyping (RP/SLA) prototype and Machining Center (CNC) prototype.

    A: SLA/RP prototype: The SLA/RP prototype is mainly produced with laser rapid prototyping technology.

    B: CNC prototype: It is mainly a hand board produced by a machining center.

(3) 3D Print prototype: It is mainly able to generate objects of any shape directly from computer graphics data, thereby greatly shortening the production cycle of products and increasing productivity. Although still to be improved, the market of 3D printing technology has great potential, and it is bound to become one of the breakthrough technologies in the future manufacturing industry.

   3D printing has brought about a worldwide manufacturing revolution. It used to be that the design of parts depends entirely on whether or not the production process can be realized. The emergence of 3D printers will overturn this production idea, which will allow enterprises to no longer consider production when producing parts. Process problems, any complex shape design can be achieved through a 3D printer.
