3D printing is a rapid prototyping technology, it is a digital model based on the file, the use of powdered metal or plastic and other adhesive materials, through the layer by layer to build the way the object technology. Simply put that if an article is divided into a lot of thin layers, 3D printing is a layer of a layer of thin print out, on a layer covered in the next layer, and with the combination until the object print Forming.
3D printing is usually done using a digital technology material printer. In the past, it was often used in the field of mold making, industrial design, etc., and is now being used for the direct manufacture of some products, and there have been parts that have been printed using this technology.
Advantages of military applications:
Military equipment parts are mostly complex shape, the use of traditional processing methods is difficult to manufacture, nothing more than polished cutting and casting, the use of 3D printing can be directly printed out, saving working hours cost.
3D printing technology is simple, easy to operate, to avoid the outsourcing of data leakage and huge time-consuming, especially for the military industry.
The military industry for equipment research and development, improvement is very important, often a single trial production, small batch production, due to 3D printing manufacturing and data conversion time significantly reduced production cycle and cost reduction, can reduce expenses to meet other military projects The need.
