As a forward-looking product in the 3D field, 3D printers are becoming a trend that is growing rapidly. 3D printers are called to change the new creative technology of the future world. They not only change the production methods of many factories, but also bring a revolution to the manufacturing industry. They will also enter our families and bring huge amounts to industrial production and our lives. Revolutionary change.
3D printer features advantages
3D Printers (3D Printers), also known as 3D printers, are devices that can "print" out real 3D objects. Functionally, like laser forming technology, layered processing and superposition forming, that is, adding materials by layer by layer to generate 3D Entity, completely different from traditional material removal technology, is called "printer" with reference to its technical principle, because the process of layered processing is very similar to inkjet printing.
The 3D printer is a powerful tool for rapid prototyping and mold making. Compared to other additive manufacturing techniques, it can produce any shape part directly from computer graphics data without machining or any mold. Find the best balance between the structural complexity of the part and the light weight. 3D printer has the characteristics of high printing precision, fast speed, low price, high ease of use, etc., which greatly shortens the product development cycle, reduces production cost and improves production efficiency.
How 3D printer works
3D printing is a form of additive manufacturing technology in which three-dimensional objects are created by successive physical layers. 3D printing is the reverse process of tomography. Tomography is the process of “cutting†something into a myriad of superimposed slices. 3D printing is printed one by one and then superimposed together to form a solid object. The printing process of each layer is divided into two steps. First, a special glue is sprayed on the area to be formed. The glue droplet itself is small and difficult to spread; then a uniform layer of powder is sprayed, and the powder will cure quickly when it encounters the glue. Bonding, while the area without glue remains loose. In this way, under the alternation of a layer of glue, the solid model will be “printedâ€. After printing, the loose powder can be removed to “plan†the model, and the remaining powder can be recycled.
The 3D bioprinter has two printheads. One printhead can hold up to 80,000 human somatic cells, called "bio-ink", and the other can print "bio-paper". The main component of bio-paper is water gel. A scaffold for cell growth. The "bio-ink" cells and the "bio-paper" gel are printed alternately until the new organ is printed. 3D printers can print 3D models from a variety of materials while using 3D assisted design software. According to the principle of 3D printer, as long as the computer can design the product or scan the original object 360°, whether it is a house or a prosthetic heart valve, the printer can make it according to the drawings. If used to print mechanical assembly drawings, gears, bearings, tie rods, etc. can be normally moved, and the shape and position of the cavity, groove and the like are accurate. Different printer manufacturers provide different printing materials, and the printed materials can be organic or inorganic materials such as rubber, plastic, and human organs.
3D printer application and technology development
Wide range of applications for 3D printers
As a high-tech technology, 3D printing technology integrates CAD/CAM technology, laser technology, photochemistry and materials science into the design of various fields such as product design, architectural design, industrial design and medical product design. It is quick and convenient to obtain a full-color physical model, which is convenient for re-improving the CAD design model, saving the cost and development time of designing the manufacturing process equipment for the wrong design. The application fields of 3D printing are more and more extensive. At present, it is mainly used in the production of models in industries such as industry, medical, construction, aerospace and machinery manufacturing, including sophisticated medical equipment and handicrafts.
In industrial production, 3D printers can directly print models, model inserts and patterns for metal castings. In the medical field, 3D bio-printers can use cells from the patient's own body, using layers of bio-structural blocks to create real living tissue that prints out skin, bone and cartilage tissue. In the field of architecture, 3D printers can quickly produce accurate models for important precision components of curved profiled buildings, achieve the level of craftsmanship that cannot be achieved with traditional architectural models, and even “print†a complete building. In the geospatial world, 3D printers can easily convert GIS data into 3D terrain and urban landscape models or sand tables. In the field of education, 3D printers can bring abstract concepts into the real world, transforming students' ideas into real three-dimensional color models that they can hold in their hands, making teaching more vivid. In the field of entertainment art, 3D printers make it easy to create custom avatars and statues based on 3D data generated by video games, 3D animation and other creations.
