We often hear about 3D printing (a kind of rapid prototyping technology) in our daily life, but for those who have not been exposed to 3D printers, it is just a concept, and they do not have a deep understanding of its structure and printing principle? Now let's introduce the difference between 3D printing and ordinary printing in Shanghai from several aspects?

1/Different printing consumables: The consumables of ordinary printers are mainly composed of ink or toner and paper. The main printing materials of 3D printer are engineering plastics, resins and chemical formula: CaSO4· 2H2O powder, thermoplastic, titanium alloy, photopolymer, liquid resin. The common feature of these materials is that they are easy to form, and these printing materials are specially treated.

2/The printing structure is different: ordinary printing can only be plane printing, while 3D printing (a kind of rapid prototyping technology) is three-dimensional printing. 3D printing is usually realized by digital technology material printer. It is often used in mold manufacturing, industrial design and other fields to manufacture models, and then gradually used in the direct manufacturing of some products. There are already parts printed with this technology.

3/Different printing carriers: ordinary printers need templates that can construct various plane graphics, such as word, powerpoint, PDF, photoshop, etc., while 3D printing (a kind of rapid prototyping technology) is based on 3D graphics.

4/Different printing time: It may only take a few minutes to print dozens of pages and hundreds of documents, while 3D printing may take several days or more than a month. To put it more generally, a prototype is one or several functional templates made according to the product appearance drawing or structure drawing to check the appearance or structure rationality without opening a mold. At present, the prototype is also called the first board in different places.
