PTJ Inc Case studies Of 3D Printing

The development of manufacturing methods has gone through three stages: equal material manufacturing, subtractive manufacturing, and additive manufacturing.
  • (1) Equal material manufacturing refers to the production of products through casting, forging, welding, etc. The weight of the material is basically unchanged, and it has a history of more than 3,000 years.
  • (2) Subtractive manufacturing refers to the use of turning, milling, planing, grinding and other equipment to cut materials to achieve the design shape after the industrial revolution. It has a history of more than 300 years.
  • (3) Additive manufacturing, that is, 3D printing, refers to the use of light curing, selective laser sintering, fusion accumulation and other technologies to accumulate materials little by little to form the required shape.

Whether it is equivalent material manufacturing or subtractive material manufacturing, in the industrial manufacturing process, product design will be affected and restricted by the manufacturing process. Designers cannot let go of imagination and pursue the most ideal product effects. With the perfect combination of 3D printing china technology and traditional craftsmanship, industrial manufacturing has become simpler and more efficient; for additive manufacturing, any product data can be achieved through 3D printing, which is important for industrial manufacturing. The field has brought revolutionary changes.
