3DP

Introduction of 3DP

3DP (Three Dimension Printing) is one of the common 3D printing technologies. The principle of 3DP technology is shown in Fig. 1. The powder material is laid flat on the printing platform. Under the control of the computer model, the color adhesive will selectively spray from the inkjet print head, which will cause the powder to cure. After one layer of bonding is complete, the printing platform drops and the above steps are repeated until the entire part is complete. The strength of the parts bonded with the binder is low, so they need post-processing, which is one of the features of 3DP technology.

Services

CD BioSciences is a company specializing in 3D printing services, where you can solve your 3D printing needs in one stop. CD BioSciences offers multiple 3D printing services, including 3DP, and has a wide range of materials available to meet the needs of different applications.

3DP technology is also known as binder jetting and inkjet powder printing. Although parts are made by powder bonding, 3DP differs from SLS technology in that it is not bonded by laser melting, but by the nozzle with a binder (such as silicone) to print the section of the part on the material powder, so the printing process does not need to be carried out under protective gas.

CD BioSciences offers 3DP technology that can print colorful parts by controlling the color of the binder. In addition, materials that have not been sprayed with a bonding agent always remain dry powder, play a supporting role in the molding process, and are easy to remove after molding. 3DP technology does not require high-cost components such as lasers, is easy to operate and maintain, has fast processing speeds, and will develop into one of the most competitive technologies.

Materials for 3DP

Almost any material that can be powdered can use 3DP technology, and the material selection is very wide.

• Ceramic powder
• Metal powder
• Plastic powder
• Sand

3DP technology is very demanding on the powders used for molding, and CD BioSciences offers a wide range of high-quality powder materials and can customize the materials according to the needs of manufacturers.

Applications of 3DP

With the 3DP process, components and mold prototypes of full-color appearance can be produced quickly, which are mainly used in the following industries.

• Artwork
• Architecture
• Pharmaceutical industry
• Education

Advantages of 3DP

• Fast forming speed
• Full color printing can be achieved, which greatly improves the flexibility of creation
• Low cost
• High material selectivity
• No support material is required.
• Achieve large -scale printing
• The printing process is relatively clean

3DP technology has developed rapidly in recent years. With its advantages of printing color prototypes, fast, low cost, wide range of applications, and high degree of fineness, 3DP technology will be widely used. CD BioSciences has an experienced expert team and is committed to providing professional 3DP technology for manufacturers in various industries.
