What is Directed Energy Deposition 3D Printing Technology?

 The application of 3D printing technology can be traced back to the stereolithography (SLA) technology developed by Charles Hull of the United States in 1986. In the next 20 years, a number of 3D printing technology patents such as layered solid manufacturing (LOM) and fused deposition modeling (FDM) came out one after another. , SLM solution, etc. 

Since 3D printing technology started earlier in European and American countries, after more than 30 years of development, technologies such as SLA (stereolithography) and SLS (selective laser sintering) have been relatively mature. It is relatively perfect in R&D and manufacturing of high-temperature metal materials and equipment.




What is 3D printing technology?


3D printing technology is a kind of rapid prototyping technology. It decomposes the three-dimensional digital model designed by the computer into several layers of plane slices, and then the powdery, liquid or filamentary plastic, metal, ceramics or sand can be glued by the 3D printer. Composite materials are superimposed layer by layer according to sliced graphics, and finally piled up into a complete object.


The development status of 3D printing technology


Since the beginning of the 21st century, various subdivisions of additive manufacturing technology have been further developed, such as digital light processing (DLP), multi-head jet technology (PloyJet), etc. have been developed. Special 3D printing materials for custom 3D printed figurine and 3D printing equipment have also emerged as the times require. At present, the 3D printing industry in the world has generally formed a complete industrial chain covering raw materials, parts, processes, equipment, and services. Some key enterprises have been upgraded from single equipment manufacturers to comprehensive solutions from design to terminal parts manufacturing business.

What is Directed Energy Deposition (DED)


DED technology uses laser or other energy sources to generate a molten pool in the deposition area and move it at high speed. The material is directly sent into the high-temperature melting area in the form of powder or filament, and is deposited layer by layer after melting. It is called laser directed energy deposition 3D printing technology. The laser metal powder deposition technology (laser metal deposition-LMD) in the DED technology classification uses laser as the energy source and metal powder as the processing material.



Magic Box is the first producer to produce real face customized 3D printed figurines, using 3D portrait modeling and AI technology. 3D printed action figure of yourself is a unique and meaningful gift for everyone. Only uploading a 2D front face photo can custom a personal 3D printed figure. And only the head is customized, and the body is made according to the product pictures! The size is 8cm high and it's an environmentally friendly resin material. 3D printing by Selective Laser Melting.

What is 3D Printing？ 3D printing is a method of additive manufacturing, which can process objects layer by layer according to 3D model files. 3D printing can ignore the complex structure of the model, and print out the model, which can be well personalized and customized. Production. The molding method of 3D printing is very suitable for the production of toy models. Magic Box will introduce to you the main advantages of 3D printing toy models  . The general process of 3D printing toy models is conception → manual drawing of floor plans → computer software drawing of 3D modeling → 3D printing → re-verification. After several iterations, the design is finally completed, and 3D printing generally only takes one day to complete, which can greatly reduce production time. The Main Advantages Of 3D Printing Toys: (1) Personalization of toys is easier: because of 3D printing, customization or highly personalization of toys is already very easy to achieve. (2) Development of new toy produ...

What is the Development of 3D Printing

With the development of society, there are always some new technologies appearing in our lives and playing an increasingly important role. The 3D printing we are going to talk about today is such a technology. 3D printing has only appeared for decades, but its development is visible. Many people may mention that the first thing that pops up in the mind of 3D is 3D movies watched in cinemas, which is indeed a kind of 3D technology. application, but today we are talking about 3D printing, a technology that is more widely used in our lives and has changed our lives the most. 3D is now widely used in many fields such as manufacturing, medical treatment, education, aerospace, military and so on. Since the birth of 3D printing technology in the 1980s, it has been considered as a rapid prototyping technology for a long period of development, but in the past five to ten years, the application field of 3D printing technology has gone beyond the prototype Instead, it has gradually evolved toward...
