(How to Break Through the Bottleneck of 3D Printing with Aluminum Alloy Materials with Excellent Performance?)

As metal 3D printing occupies an increasing proportion in advanced
manufacturing, the importance of metal powder materials in the upper reaches of
the industrial chain is becoming more and more prominent. Among many metal
powder materials, aluminium alloy powder seems to be a special one.

First of all, aluminium alloy powder is dangerous. It is flammable, easy to
oxidize, and absorbs moisture, which brings considerable troubles to the
production, storage and transportation of aluminium alloy powder. 

Secondly, in
the interaction with the laser, aluminium alloy has a high laser reflectivity
(about 91%), which requires high enough energy to melt it. Therefore, metal 3D
printing equipment generally requires relatively high laser reflectivity (about
91%). High power.

Thirdly, the aluminium alloy powder is sticky and has low fluidity, which
brings excellent problems to the metal powder coating. It can't spread powder,
and it isn't easy to print. Besides, aluminium alloy is easily oxidized, and its
oxide film is very dense, which will increase the difficulty of laser melting.
The generated oxide film will also hinder the bonding of the cladding layer and
the substrate. Therefore, for a long time, aluminium alloy 3D printing is almost
a job that metal 3D printing service providers are unwilling to undertake.

However, aluminium alloy is widely used in many fields such as aerospace,
military industry, vehicles, ships, electronics, industrial manufacturing, and
civil applications due to its lightweight, high strength, high thermal
conductivity, corrosion resistance, and electrical conductivity. In daily life,
aluminium is also one of our most common metal materials.

Unfortunately, the progress of aluminium alloy 3D printing in various fields
has been plodding. This can be attributed to the following three reasons:

First, the cost of aluminium alloy is meagre, and metal 3D printing itself is
an expensive technology, so aluminium alloy processed by 3D printing has no
price advantage.

Second, the aluminium alloy materials that can be printed are minimal. The
aluminium alloy 3D printing materials currently on the market are mainly
AlSi10Mg and AlSi7Mg. Although some high-strength aluminium alloy 3D printing
materials have been developed, they are still in the hands of a few companies
and have not yet been obtained and widely used. The aluminium alloy 3D printing
materials designed for specific applications, such as aluminium alloy for heat
conduction and aluminium alloy for electrical conduction, have hardly been
developed.

Third, although metal 3D printing technology has developed rapidly in recent
years, in practical applications, most companies have not explored the
advantages and core competitiveness of metal 3D printing. Metal 3D printing has
not been integrated into the product development process, and most manufacturing
companies have not enjoyed the actual benefits of technology upgrades, product
upgrades and performance improvements brought by metal 3D printing. This, of
course, depends on the joint efforts of upstream and downstream industries.
