Rapid prototyping 3D printing technology

Nov 03,20

3D printer is a new word emerging in the civil market in recent years.Another name in the field of expertise is rapid prototyping.
3D printing is often used in mold manufacturing, industrial design and other fields to make models, and then gradually used in the direct manufacturing of some products.
It has a profound impact on the traditional technological process, production line, factory mode and industrial chain combination, and is a representative disruptive technology in the manufacturing industry.Indeed, 3D printing is better suited to small-scale manufacturing, especially high-end customised products such as car parts.Although the main material is still plastic, metal materials will definitely be used in 3D printing in the future. Common materials of 3D printing include nylon glass fiber, durable nylon material, gypsum material, aluminum material, titanium alloy, stainless steel, silver plating, gold plating and rubber materials.

1, 3 d printers principle is very simple, popular culture, first of all, on the computer design of a complete 3 d model (also become computer auxiliary design), and then "print materials such as gel or powder into the printer, then the printer connected to a computer, you can through the computer control of the" printed materials "superimposed layers and the three dimensional model, the blueprint of computer has finally become real.The 3D printing technology, which creates 3D objects through continuous physical layers, is a form of superposition manufacturing process, which has the advantages of fast speed and low price compared with traditional superposition manufacturing process.
2. Advantages of 3D printing technology
The principle of 3D printing technology determines its advantages: (1) It does not need to cut, cut objects, also do not need mold;@ Processing speed
Very fast, short production cycle;(3) For some complex structure, the volume of the object is the most obvious advantage, the traditional manual is difficult to complete the model for it is very simple, because it is a body, there is no need to go to the second processing;Can be batch, can be online, can also achieve remote control.
3. Defects of 3D printing technology
Of course, 3D printing technology also has some defects: (1) The cost of the printer is very expensive, the cost of operation and maintenance is also very high;(2) the material requirements of forming objects are very high;The amount of software data processed by 3D is very large, plus the software has a strong correlation with the physical printer;) Software operation is difficult, the printer operation is difficult to get started.
4. Major trends in the future development of 3D printing technology
With the further development and maturity of intelligent manufacturing, new information technology, control technology, material technology and other technologies have been widely applied in the field of manufacturing, and 3D printing technology will also be pushed to a higher level.In the future, the development of 3D printing technology will reflect the main trends of precision, intelligence, generalization and convenience.
