Existing in the more popular metals on the market today3D printingThe three main technologies are DMLS (Direct Metal Laser Sintering), LMS (Laser Metal Sintering), and EBM (Electron Beam Melting). 3D printing is the ideal choice when other technologies fail to produce complex and delicate parts efficiently and easily.

Basic concepts of metal 3D printing:

The core idea of metal 3D printing technology originated in the United States in the late 19th century, however, it did not take shape until the mid-1980s, when Hull, an American, invented the 3D printer in 1986. China began researching 3D printing technology in 1991, and around 2000 these processes began to evolve from laboratory research towards engineering and productisation. At that time it was called Rapid Prototyping (RP), which means physical models before developing samples. Today it is also called rapid prototyping, additive manufacturing. However, for the sake of public acceptance, this new technology is collectively referred to as 3D printing, which is a type of rapid prototyping technology that uses digital model design as the basis for a technology that uses materials that can be bonded together, such as powdered metals or resins, to construct a three-dimensional object with the help of layer-by-layer “additive” printing. Metal 3D printing has been called “the idea and technology of the last century, the market of this century”.

Metal 3D printing features:

1. High precision.

At present, the accuracy of metal 3D printing equipment can basically be controlled below 0.05mm.

2. Short cycle.

With metal 3D printing, the production process is mould-free, which allows the production time of the model to be significantly reduced, usually by a few hours, or even within a few minutes, to complete the printing of a model.

3. Personalisation is possible.

With metal 3D printing, there is basically no limit to the number of models that can be printed, whether it's one model or multiple models, all of which can be produced at the same cost.

4. Diversity of materials.

A metal 3D printing system is often able to print in a variety of materials, and this material diversity meets the needs of a wide range of fields.

5. Relatively low cost.

Nowadays, metal 3D printing systems are expensive, and so are the metal materials used for 3D printing, however, if they are used to create personalised products, the cost of making them is relatively low.

3D printing service is a technology, it is digital, intelligent, low-cost, short-cycle manufacturing technology, through a simple two-dimensional layer-by-layer increase in the material directly to achieve three-dimensional complex structure manufacturing. It breaks through the principle limitations of traditional parts forming and processing manufacturing technology, theoretically, it does not rely on the traditional industrial infrastructure, only through a simple “two-dimensional digital printing”, can directly manufacture any internal structure, shape and geometry of high-performance three-dimensional complex structures.

In view of the transformative advantages compared with the traditional forming manufacturing technology, 3D printing technology has become a hot direction in the field of equipment manufacturing technology, as well as a hot direction in the field of structural design technology, or a hot direction in the field of new material technology. As an important branch of 3D printing technology, metal 3D printing technology plays an important role in the manufacture of high-performance metal components.

In the development process of metal 3D printing technology, metal 3D printing materials are extremely important material basis, to a certain extent, the development of materials determines whether 3D printing can have a wider range of applications. Nowadays, metal 3D printing materials mainly cover engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials, etc. In addition, coloured gypsum materials, artificial bone powder, cellular biological raw materials and sugar and other food materials have also been applied in the field of metal 3D printing.

Metal 3D printing will use some raw materials, these raw materials were developed specifically for metal 3D printing equipment and process, they are different from ordinary plastic, plaster, resin, etc., and their forms are usually in powder, filament, lamellar, liquid and so on. Generally speaking, due to the type of printing equipment and operating conditions are not the same, the particle size of the powdered metal 3D printing materials used is 1 to 100 μm, is not the same, and in order to maintain good fluidity of the powder, the powder is often required to have a high degree of sphericity.
