The advantages of metal AM over injection molding

The development of industrial production in the modern world cannot do without the use of new technologies. Their use is not a fashionable trend, but a necessity, because it is the only way to ensure the production of relatively cheap, high quality and reliable products. In some cases, new technologies can make significant improvements even in traditional production. This is precisely what is characteristic of the so-called additive technologies. In this article we will discuss the advantages of metal AM over injection molding.

What is meant by the term additive technology?

Additive technology refers to the process of manufacturing products on the basis of 3D computer models. It is built layer by layer, gradually, which is why this process is often referred to as growing. This circumstance significantly distinguishes additive technology from traditional, which implied a process reminiscent of the sculptor’s work, when cutting off excess material from the workpiece, or changing its geometric parameters. 

What are the advantages of additive technology?

  • Unique characteristics of the resulting product. Layer-by-layer growth makes it possible to obtain a product with improved properties. An example of this is the products that are produced on metal printers. In terms of their characteristics and quality, such parts proved to be much better than their counterparts created by traditional technologies: casting or machining.
  • Significant savings in consumables and low production costs. Traditional production methods are often very costly, and the loss of consumables can reach 80% or even more. Unlike traditional technologies, additive technologies are much more economical, because the software of the equipment calculates the exact amount of consumable materials. 
  • Additive technologies make it possible to produce products with complex geometry. Traditional methods, such as casting or stamping, do not make it possible to produce very complex products in terms of geometry. If you want to get parts for cooling systems with a mesh structure, you can’t do it with traditional methods. On the other hand, industrial printers make it possible to grow models of almost any degree of complexity.
  • Mobile production and fast data exchange. Additive technologies use computer models of future products, which can be transferred not only to development, but also forwarded to colleagues on the other side of the world in a short time. This does not require traditional drawings, dimensional models, etc.
