2023-12-22 14:30

3D metal printing materials can be classified based on their composition and characteristics. The following are several common classifications of 3D metal printing materials and their advantages and disadvantages:


1. Titanium alloy:
Advantages: Titanium alloy has good strength and corrosion resistance, suitable for aerospace, medical, and automotive fields. They have low density, light weight, and good biocompatibility.
Disadvantages: Titanium alloy materials are relatively expensive, and high temperatures need to be controlled during the printing process, resulting in slower printing speed.


2. Aluminum alloy:
Advantages: Aluminum alloy has good strength and thermal conductivity, making it suitable for fields such as aerospace, automotive, and consumer goods. They have lower density, light weight, and relatively low cost.
Disadvantages: Aluminum alloys have a lower melting point and are prone to thermal deformation, requiring precise temperature control.


3. Stainless steel:
Advantages: Stainless steel has good strength, corrosion resistance, and high temperature resistance, making it suitable for manufacturing tools, aerospace, and medical devices. Their costs are relatively low.
Disadvantages: Stainless steel has a high melting point and requires high-temperature printing, resulting in slower printing speed.


4. Nickel based alloys:
Advantages: Nickel based alloys have excellent high-temperature and corrosion resistance, making them suitable for fields such as aerospace, energy, and chemical engineering. They have good mechanical properties and wear resistance.
Disadvantages: Nickel based alloys have a higher cost and require high temperature control during the printing process.


5. Titanium aluminum alloy:
Advantages: Titanium aluminum alloy combines the advantages of titanium alloy and aluminum alloy, with good strength, lightweight, and corrosion resistance, suitable for aerospace, automotive, and sports equipment fields.
Disadvantage: Titanium aluminum alloy has a high melting point and requires high-temperature printing.
When selecting materials, it is necessary to consider the application requirements, cost, and compatibility of printing equipment.
