What role is the additive manufacturing to 3D printing?

Before finding out what role accretion production plays in the 3D printing industry, what must be known as “accretion production”?  

Additive Manufacturing, AM is the process of manufacturing products based on a three-dimensional digital design. Other names of AM include rapid prototyping, digital production (direct digital manufacturing), gradual production, cumulative manufacturing, … AM is gradually changing the way businesses make create production. Today, we can adjust product design easily with just a few mouse clicks or design sophisticated and sophisticated products without using any template.


With the traditional production process, to get a complete product requires workers to drill, stamping, turning on a block of material. With AM, each layer of extremely thin material is stacked on top of each other to create a complete three-dimensional product. The back layer adheres to the previous layer by completely melting (or partially) the material that makes up the product. In addition, instead of using nozzles and printers, businesses can also use lasers to melt powdered materials. Once molded into shape, the product is dried and allowed the layers to stick together.  

What are the benefits that accretion production brings to the 3D printing industry?  

The traditional production process has inherently provided businesses with numerous choices of shapes and designs, but AM can do more and the process is more flexible.

For example, AM can be used to create hollow-hole designs in the middle via a single stage. If you produce it in the traditional way, you need to make it easy to weld many pieces together to produce the finished product.

Products manufactured from AM production processes are also more reliable, lighter, more economical, and also help manufacturers shorten the time from design to mass production. Your engineers now do not have to meet continuously to adjust design drawings. Through CAD software, all edits can be done with just a few clicks and the production process can be completed in just one night.


The applicability of additive manufacture is limitless, due to the superior production capacity compared to the old technology.

For example, in automobile manufacturing, the accretion production will replace the user reading and understanding drawings because everything is digitized and simulated in 3 dimensions. Information from CAD software is provided directly to the machine, all specifications will be simulated according to the drawings but the production time will be reduced by 40-90% compared to the traditional production process. Ford Motor is one of the leading brands utilizing AM to make models. The shortened process helps businesses save millions of dollars.

In aircraft manufacturing, thanks to the ability to produce more complex and lightweight components, AM is quickly applied in the aviation industry. In the 2017 Paris Air Show, the Boeing 787 Dreamliner – the first FAA-qualified aircraft with titanium structure built with 3D printing has received praise from experts.

In particular, the technology of additive manufacturing in 3D printing has contributed significantly to the medical industry. AM helps produce prosthetic devices such as prosthetic limbs, dentures, etc. Not stopping there, AM can create a new revolution in medicine with the ability to make skin and bone cuticles. cartilage, lining between joints, …

With the advancement of technology, 3D printing can be applied to various fields from automotive, aviation, medicine to jewelry to any kind of material.
