What Are The Application Of Laser 3D Printing?

3D Printing (3DP) is a rapid prototyping technology. Based on digital model files, it uses powdered metal or plastic and other bonding materials to construct objects by printing layer by layer.

3D printing services are commonly used for model making in the following fields: rapid prototyping, mold making and industrial design, and then gradually used for direct manufacturing of certain products. 3D printing technology can be used in rapid prototyping services, jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other applications field.

The 3D printing industry is developing rapidly. Compared with traditional manufacturing, 3D printing can overcome some shortcomings of traditional manufacturing. At present, some application scopes and fields of 3D printing have been recognized by the manufacturing industry. After hundreds of years of accumulation and development, the traditional manufacturing industry has been very mature in terms of production technology, production technology, materials, etc., and has formed an industrial foundation with complete facilities, complete functions, and widely recognized by all walks of life. At this stage, 3D printing and traditional Manufacturing is not a relationship of substitution and substitution, but a relationship of complementarity.

At present, the demand for laser 3D printing is mainly in the aerospace, medical, manufacturing, and many other industries, we explain:

1: Aerospace

A key part developed by traditional casting technology is always unqualified when the Chinese J-15 is installed and tested. At that time, in the case of very tight time and lack of the same metal materials, the use of laser 3D printing technology directly printed a metal part with relatively close performance and finally passed the detection.

2: Medical

Human beings are very fragile creatures, and if you are not careful, your body will be damaged beyond repair. Human cells and tissues can now be grown using 3D printing technology to create medical implants that will improve the quality of life of disabled people.

3D-printed human organs have many advantages, it can be accurately matched according to human characteristics so that the printed organs and tissues work better in the human body.

For example, the 3D-printed blood vessel tissue in the above figure and the 3D-printed heart in the following figure can be accurately matched according to human characteristics

At present, 3D printing has successfully printed various organs of the human body, and these organs and tissues have been applied in surgery.

The research of laser 3D printing technology in medical applications has involved nanomedicine, pharmaceuticals, and even organ manufacturing. We believe that 3D printing technology will certainly make customized medicines a reality in the future to alleviate the current shortage of organ donors.

3: Industrial design

3D printing can offer advantages for industrial design. In the early stages of design, solid mock-ups can provide you with valuable information, both functionally and creatively. For example, these lifelike solid models are 3D printed.

Physical models are the most effective tool for communicating with your customers, and they are also the best tool for evaluating digital models before moving data from the computer to the production line, which can greatly reduce the development cycle.

4: Building property

3D printing is already common in the construction industry. We can use 3D printing to directly print out architectural models, such as these two buildings so that users can be clear about the style, style, and even color of the building, and its authenticity can reach 100%. If the user wants to know more about it, we can even print out personalized home improvement designs and three-dimensional physical models of building units. For example, these two three-dimensional house types and home decoration design models.

5: Manufacturing

3D printing is still far from large-scale applications, but it has taken a step forward in the manufacturing field, such as direct printing solar cells.

Complex parts that are internally porous and difficult to make using traditional techniques. It can even print out parts of a racing car

6: Personalized Accessories

With the continuous development of society, people's personalized needs are also more and more 3D printing can meet this demand. For example, we can directly print out personalized jewelry such as fashion jewelry with personal wishes.

3D printing technology cannot ignore its own advantages. Industry experts believe that:

(1) The distributed manufacturing model based on 3D printing and big data will completely connect the Internet and manufacturing.
(2) To build a distributed manufacturing point, one of the core problems to be solved is to have a designer platform based on huge design works.
(3) Internet + 3D printing platform + distributed manufacturing mode will be the future development trend of the 3D printing industry.
And the limitations of 3D printing technology are mainly reflected in the following aspects:

(1) The precision is low, and the temperature has a great influence on the FDM molding effect, while desktop FDM3D printers usually lack constant temperature equipment and additive manufacturing. In addition, the discharge part lacks control components, making it difficult to accurately control the discharge shape and molding effect. For these reasons, the finished product accuracy of the desktop fdm3d printer is usually 0.1~0.3mm.
(2) Low intensity. Due to the limitations of technology and materials, the performance strength of printed matter is low, especially the material strength in the Z-axis direction is weak, which cannot reach the industrial standard.
(3) It takes a long time to print, and it needs to be printed step by step according to the cross-sectional shape. Due to certain restrictions on the molding process, it takes a long time to make large objects, so it is not suitable for manufacturing large objects. Support material needs to be added during the molding process. After printing, it needs to be peeled off. With the advancement of technology, water-soluble support materials have been available on the market, and this shortcoming is gradually being overcome.

Metal 3D printing already provides a variety of applications in many industries, and more importantly, the number of such applications is still growing. Additionally, a host of competing companies offering 3D printing products and services are increasing their catalogs of printable materials to find new customers and expand into new areas.

Over the next few years, we can expect the 3D printing industry to continue on the same growth path. Metal 3D printing will eventually become the disruptive technology we expect.
