3D printer, also known as three-dimensional printer, three-dimensional rapid prototyping. 3D printers are different from traditional printers. Their raw materials are not ink, but various materials, such as building materials, food materials, DLP materials, etc.; their products are not paper objects, but various parts, models, food or machines. 3D printing technology has been used in many fields such as jewelry, footwear, construction, medical treatment, aerospace, etc. 3D printing is gradually changing our lives.
3D printing is an additive 3D manufacturing technology. A 3D printer is a rapid prototyping machine that constructs objects by printing them layer by layer. Its basic principle is based on digital model files, using adhesive substances as materials, and constructing objects by printing layers of adhesives. However, the stacking methods of 3D printers are various, which makes the principles different. The following are several commonly used stacking technologies for China SLA 3D printers:
1. "Inkjet": The nozzle of the 3D printer sprays a layer of liquid plastic material on the mold tray, and puts it under ultraviolet light for corresponding treatment, so that the mold tray drops a small distance to provide space for the next layer of stacking.
2. "Fusion deposition molding": melt plastic in the nozzle of the 3D printer, and deposit plastic fibers to form a thin layer for stacking.
3. "Laser sintering": 3D printers including mid size resin printer use powdery particles as printing raw materials. First, a thin layer of powder is sprayed on the mold tray, and after being melted into a specified shape, it is solidified by a liquid binder.
4. "Laser sintering enhanced version": When a 3D printer prints structures containing holes or cantilevers, in addition to "laser sintering", substances such as gelling agents need to be added to the material to provide support. This part of the powder will not be cast. Finally, it can be washed away with water or air flow to form gaps, which play the role of occupying space.
The technical characteristics of 3D printing are consistent with the next step of human development
▶ High flexibility in production:
It can manufacture 3D entities of arbitrary complex shapes. To produce part models of different shapes, it is only necessary to change the CAD model, readjust and set the parameters.
▶ Directly driven by CAD model, highly integrated design and manufacturing:
3D printing technology realizes the seamless connection of CAD/CAM and truly realizes the integration of design and manufacturing. It is a typical embodiment of digital design and manufacturing technology.
▶ Production cost has obvious constant characteristics:
The cost of the product has almost nothing to do with the batch size and complexity of the product.
▶ Highly automated:
The process is fully automatic, without manual intervention, and can basically realize unattended production.
