3D Printers, also known as three-dimensional printers, are a type of rapid prototyping process equipment that can construct three-dimensional objects by printing layer by layer based on digital model files. This technology is called additive manufacturing. Unlike traditional subtractive manufacturing (such as carving or milling), 3D printing creates objects by stacking materials layer by layer in three-dimensional space.

3D printing technology usually uses powdered metal, plastic, or other bondable materials as printing materials. The materials are heated inside the printer and deposited layer by layer in a predetermined path until a complete three-dimensional object is finally formed. This process can be achieved through a variety of different technologies, including Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), etc.


3D printers are widely used in mold manufacturing, industrial design, architecture, automobiles, aerospace, medical care, education, art, and personal manufacturing. For example, in the medical field, 3D printing can be used to create customized prostheses, teeth, and bone implants; in the aerospace field, it can be used to print aircraft parts; in the construction field, it can even print the structure of entire buildings.

With the development of technology, the price of 3D printers has gradually reduced, making it affordable for individuals and small studios, which provides new possibilities for innovation and personalized production.

3D printing technology is widely used in many fields. The following are some main application fields and their corresponding actual implementation projects:


Aircraft parts: Airbus uses 3D printing technology to manufacture aircraft parts, such as certain parts of its A350 XWB aircraft.

Zero One Space OS-X6B rocket: On February 5, 2021, Zero One Space Technology Group Co., Ltd.'s OS-X6B rocket used 3D-printed attitude control power system products for the first time and completed a flight test.

The world's first fully 3D-printed rocket: On March 23, 2023, the world's first fully 3D-printed rocket completed its first flight on the LC-16 in Cape Canaveral, Florida.


Medical field:

Customized implants: 3D printing technology is used to create personalized hip implants, such as Stryker's 3D-printed hip products.

Surgical models and guides: Doctors use the patient's CT or MRI data to create surgical models through 3D printing technology to help plan the surgical process and improve the success rate of the operation.

Dental applications: 3D printing technology is used in dentistry to manufacture tooth models, crowns, and bridges, among other things.


Automobile industry:

Prototyping: Automakers use 3D printing technology to quickly create prototype vehicle parts and speed up the design and testing process.
