3D Printing Nitinol Rod is one of the products of nitinol memory alloy. Nickel-titanium memory alloy makes 3D printing metal materials more resistant to high temperatures through new heat treatment technology.

 

Although 3D printing technology can efficiently manufacture complex metal parts, the printed metal parts are often deformed by force and heat and have the problem of not being durable. For this reason, the heat treatment technology developed by the Massachusetts Institute of Technology may make This situation no longer occurs.

 

The challenge to the durability of existing 3D printed metal parts is a phenomenon called "creep", in which solid materials deform slowly and permanently under stress and high temperature, especially in 3D printing, where metal materials are made of The composition of fine grains is more prone to creep phenomenon.

 

Therefore, the MIT team developed a directional recrystallization heat treatment process to make the grains larger and less prone to creep.

 

In the laboratory test, the 3D-printed nickel alloy rod will be placed in a room temperature water bath directly under the induction coil, and then slowly pass through the coil vertically at different speeds, slowly heating each part of the nickel alloy rod to 1,200 C~ 1,245 C, creating a steep thermal gradient between the metal interior, the coil, and the water.

 

This gradient turns the metal's microscopic grains into larger "columnar" grains. In terms of material properties, the optimal temperature falls at 1,235 C and a drawing speed of 2.5 centimeters per hour, while depending on the purpose of the 3D printed part, the grain structure of individual items can be changed by changing the temperature and speed during processing.

 

At present, the team also plans to test new technologies similar to gas turbine or jet engine blades. These parts must withstand continuous mechanical stress and high temperature. , More efficient 3D printing design, 3D printing nitinol rods can be used.

1) Customization: 3D printing allows for the creation of unique nitinol rods with custom shapes and sizes, which can be tailored to the specific application requirements.

2) Reduced waste: 3D printing can use the exact amount of material necessary for the production of the nitinol rod, allowing for a reduction in waste and ultimately leading to cost savings.

3) Precision: 3D printing technology allows for a high level of precision in the production process, leading to more consistent and uniform nitinol rods.

4) Complexity: 3D printing can create complex designs and structures that would be difficult or impossible to produce with conventional manufacturing techniques.

5) Time savings: 3D printing can produce nitinol rods more quickly than traditional manufacturing methods, allowing for faster production and turnaround times.
