The following is the outlook for the future of 3D printing technology:1Fast Printing:

In the future, the speed of 3D printers will be further increased, resulting in faster printing. At present, the speed of 3D printing still limits its application in industrial and mass production. 2.

Wider application: In the future, 3D printing technology will be applied in a wider range of fields. For example, the medical industry will use 3D printing to print human organs, and the industrial sector will use 3D printing to manufacture complex machine parts.

3.The use of more materials: At present, the application materials of 3D printing are still relatively limited, and in the future, 3D printing materials will be more diversified and specialized, including metals, ceramics and composite materials.

4.Revolutionary manufacturing change: 3D printing technology will quietly change the production mode of traditional manufacturing, and people can print at will according to their personal needs, without the need for large-scale production.

5.Networked printing: In the future, 3D printers will be able to achieve networked printing, and intelligent control systems will be able to monitor and manage the printing process, resulting in more efficient production model macros.

At present, the main 3D printing technology of Shengzhen.

There are several ways to do this.

Light-curing stereolithography refers to the use of laser beams.

Irradiation of photosensitive resin in a resin tank.

It can be quickly cured from point to line and from line to surface, and then the lifting table lowers the height of one layer and then cures the second layer, so that the layer of superposition is repeated until the whole model is formed. The schematic diagram of its working process is shown in Figure 1.

Layered solid manufacturing uses the sheet as the raw material, and the surface of the sheet is pre-covered with a layer of hot melt adhesive.

During processing, the hot pressing roller hot-pressed the sheet to make it bond with the workpiece that has been formed below, and then use the laser to cut out the cross-sectional profile of the part and the outer frame of the workpiece on the new layer that has just been bonded, and cut out the grid aligned up and down in the redundant area between the cross-sectional profile and the outer frame, after the laser cutting is completed, the workbench drives the formed workpiece to descend and separate from the strip sheet, and the feeding mechanism makes the new layer move to the processing area again, the worktable rises to the processing plane, the hot pressing roller heats, and the number of layers of the workpiece is increased by one layer. The height is increased by one thickness, and the cross-section profile is cut on the new layer. This is repeated until all sections of the part are bonded and cut, and the solid part is manufactured in layers. A schematic diagram of its working process is shown in Figure 2.

Selective laser sintering uses a powder material as a modeling material, which is heated to a temperature close to its melting point during processing, and then the powder is flattened with rollers, and the computer controls the two-dimensional scanning trajectory of the laser beam according to the slicing model of the prototype to selectively sinter the solid powder material to form a layer of the part. After one layer of powder is completed, the working piston is lowered by one layer and the powder spreading system is covered with new powder. Control the laser beam to re-scan the sintered new layer.

Melt molding is the use of electricity to heat the filamentous hot melt material to slightly higher than the melting point temperature, under the control of the computer, the nozzle according to the cross-section profile information, the material is selectively coated on the workbench, after cooling, a layer of stuffy balance section of the workpiece is formed, after the completion of a layer of forming, the nozzle moves the height of a layer of cross-section, and coats the next layer again, so that it is stacked layer by layer until a complete three-dimensional workpiece is formed. A schematic diagram of its working process is shown in Figure 4.

What are you referring to?

3D printing is a form of additive manufacturing technology in which three-dimensional objects are created by successive physical layers. Compared with other additive manufacturing technologies, 3D printers have the advantages of fast speed, low cost, and high ease of use.

A 3D printer is a device that can "print" a real 3D object, which is functionally the same as laser forming technology, using layered processing and superimposed forming, that is, by adding materials layer by layer to generate 3D solids, which is completely different from the traditional material removal processing technology. The term "printer" is based on its technical principle, because the process of layering is very similar to inkjet printing. As this technology continues to advance, we have been able to produce 3D models that closely resemble the look, feel, and function of the prototype.

To put it simply, 3D printing is the reverse process of tomography, which is to "cut" something into countless superimposed pieces, and 3D printing is to print one piece at a time, and then superimpose them together to become a three-dimensional object.

3D printing (English: 3D printing) belongs to fast.

Rapid prototyping is a technique in which an object is constructed by stacking and accumulating layers of adhesive materials such as powdered metal or plastic based on a digital model file (i.e., "additive shaping"). In the past, it was often used to make models in mold making, industrial design and other fields, and now it is gradually being used in the direct manufacturing of some products. In particular, some high-value applications (such as hip joints or teeth, or some aircraft parts) have been printed with this technology, which means that "3D printing" is popular.

3D printing technology is usually implemented by digital technology material printers. The production and sales of this kind of printer have increased greatly since the beginning of the 21st century, and its production and sales are declining year by year.

The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields.

3D printing technology appeared in the mid-90s of the last century and is actually a rapid prototyping device that utilizes technologies such as light curing and paper lamination. It is basically the same as the working principle of ordinary printers, the printer is filled with "printing materials" such as liquids or powders, and after being connected to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer becomes a physical object. This technology is now used in many fields, and people use it to make clothing, architectural models, cars, chocolate sweets, and more.

General principle. The design process of partition D printing of 3D model is to first model by computer-aided design (CAD) or computer animation modeling software, and then "partition" the completed 3D model into layer-by-layer cross-sections, so as to guide the printer to print layer by layer.

The standard file format for collaboration between design software and printers is the STL file format. An STL file uses triangular planes to roughly simulate the surface of an object. The smaller the triangle, the higher the resolution of the resulting surface.

PLY is a scanner that scans to produce 3D files, and the resulting VRML or WRL files are often used as input files for full-color printing.

Summary. Hello dear has been queried for you Please write your outlook for 3D printing technology: 3D printing (3Dprinting) is a kind of rapid prototyping technology, a technology that uses adhesive materials such as powdered metal or plastic to construct objects by accumulating layers based on mathematical model files ("base molding method").

In the past, it was often used in mold manufacturing, industrial design and other fields to make models, and is now gradually used in the direct manufacturing of some products, especially some high-value applications (about aerospace components and human body replaceable joints) have been printed using this technology for parts, which means the popularity of "3D" printing technology. 3D printing has covered various fields such as automobiles, aerospace, consumer goods, medical care, education, architectural design, machinery manufacturing, toys and so on.

Hello has been inquired for you: 3D printing technology outlook and future development trend 3D printing technology has entered the era of rapid development, 3D printing has been given the background of the "third industrial revolution", and the rapid prototyping technology represented by 3D printing technology is regarded as the key element to trigger a new round of industrial revolution. At present, in the field of 3D printing technology, although there is a large gap between domestic and foreign countries, however, the country has led the world in some aspects, and from the "national leaders" to the "ordinary people" have given a high degree of attention and great enthusiasm to 3D printing technology, which provides an excellent opportunity to enhance the overall strength of "Made in China", and provides a good platform for the popularization and application of 3D printing and the deepening of development] I wish you a happy life <>

Hello dear. 3D printing technology has developed rapidly, but there is one aspect that needs to be improved: inefficiency.

1. Compared with traditional machining, machining is formed by subtractive materials on the basis of blanks, and usually the difference between the blank and the parts is less material, that is, there are fewer materials to be removed, and the processing is faster; 3D printing technology, on the other hand, must stack all the materials required for the physical part by additive means, and the material volume is large. Therefore, in terms of the volume of material removed or stacked, the volume of additive materials is usually larger than that of subtractive materials. Second, from the aspect of forming motion, the traditional main movement of machining is mostly rotary motion, while 3D printing technology is linear motion, the rotary stool family leakage motion is easier to achieve greater speed, and maintain the stability of a panicle, 3D printing technology scanning motion is linear motion, it is difficult to achieve a larger speed.

Therefore, 3D printing technology not only requires a large volume of processing, but also has limited movement speed, so the comprehensive processing efficiency is low.
