3D printer is a machine that creates objects by stacking materials layer by layer. It can create actual objects from digital models or CAD files, so it is widely used in many different fields, such as casting, prototype making, automobile manufacturing, electronic appliances, toy applications, education, cultural creation, architecture, etc. The principle of a 3D printer is to use a computer to control a nozzle or a laser beam to heat or spray materials in a specific direction, and then stack these materials layer by layer according to a predetermined design, and finally form a three-dimensional entity.
With the continuous development of 3D printing technology, it has become one of the important tools of modern manufacturing. Compared with traditional manufacturing methods, 3D printing has higher flexibility and customization, can produce more precise and complex parts, and can also greatly shorten production time and reduce production costs. The application of 3D printing technology continues to expand, including casting, prototype production, automobile manufacturing, electronic appliances, toy applications, education, cultural creation, architecture, jewelry and other fields. So, what are the classifications of 3d printers? According to different working principles and application fields, industrial 3D printers
can be divided into the following categories.
SLA (Stereolithography) is a common 3D printing technology, and SLA 3D printer is a 3D printer using this technology. SLA 3D printers build objects layer by layer by using a liquid photosensitive resin and curing the resin with laser light or ultraviolet light. The technology can create high-precision, high-quality models and parts for a variety of industries, including manufacturing, medical, arts, crafts, automotive, and more.
DLP (Digital Light Processing) 3D printer is a 3D printing technology that uses digital light processing technology for light curing. It works by irradiating a beam of light on the surface of liquid photosensitive resin, making it partially cured and stacked layer by layer to form the desired three-dimensional shape. DLP 3D printers generally have high printing speed and resolution, and are suitable for producing complex parts with high precision and high resolution. It is also commonly used to make jewelry, dental aligners, and other small parts.
LCD 3D printer
An LCD 3D printer is a 3D printer that uses a liquid crystal screen as a light source. They differ from other 3D printer types such as SLA and DLP in that LCD 3D printers use a liquid crystal screen with UV light for image exposure and light curing to cure the material. LCD 3D printers are generally less expensive than SLA and DLP printers and have a larger build area. Since LCD screens are used as light sources, LCD 3D printers also need to replace the LCD screen more frequently to maintain printing quality.
ACME is one of the leading manufacturers of 3D printers and smart manufacturing equipment in China, providing a full range of 3D printing solutions and services, including industrial-grade 3D printers, consumables, software, after-sales services, etc. Its industrial-grade 3D printers
are widely used in casting, prototype making, automobile manufacturing, electronic appliances, toy applications, education, cultural creation, construction and other industries, which can meet the individual needs of different industries, improve production efficiency and reduce manufacturing costs . At the same time, ACME is also actively carrying out research and development and innovation of 3D printing technology, continuously promoting the digital transformation and intelligent development of China's manufacturing industry.
In general, different 3D printing technologies and printer types have their own characteristics and can meet the needs of different fields. Choosing the right 3D printer can help companies improve efficiency, reduce costs, and achieve higher-quality production.
