3D printing technology, or more broadly understood as additive manufacturing technology, is a packaging chain that combines different stages from design, simulation, testing, manufacturing and finally inspection to create a complete three-dimensional entity. Over the past decade, 3D printing technology has made breakthrough developments in high value-added manufacturing sectors, especially the aerospace, medical and automotive industries. The applications of 3D printing in these industries are estimated to have the potential to grow from $6 billion in 2016 to $26 billion in 2022. Although it is becoming one of the leading spearheads of the Industrial network 4.0, there are still many urgent obstacles with 3D printing technology such as high cost, low output, lack of effective testing methods as well as a team of skilled engineers. These obstacles can become opportunities for Vietnam to overcome and participate in this potential industrial field.

Project goals:

The main goal of the project is to develop an electronic design platform for 3D printing technology based on a combination of multi-material optimization technology, multiple 3D printing product layers, and machine learning methods through combined data sets obtained from the design, simulation, optimization and validation of the 3D printing process. The specific goals of the project are to improve: (a) multi-feature, multi-layer, multi-material design process efficiency in 3D printing technology; (b) the ability to detect errors and early quality control of 3D printed products; (c) structural design optimization technology for 3D printing materials.


3D printing technology, one of the legs of the 4.0 industrial revolution, will give companies of all sizes as well as individuals, the means to optimally design and mass-produce products with reasonable price, convenient, fast and meets specific needs. This tool is and will drastically change the role of traditional factories. 3D printing technology will be able to print products for household use, from household electrical appliances to shoes. Thousands of industries – from cars (the first car produced using 3D printing technology has been born) and aerospace to the footwear and jewelry industries – have applied 3D technology to create products and objects by continuously accreting (or 3D printing) layers of material. This project is expected to bring the first highlight to the 3D printing industry in Vietnam.
