Every teenager is ready to answer the question - what is 3d printer? But not every experienced engineer can imagine where and how additive technologies can be applied in mechanical engineering and especially in metallurgy. This is the subject of our online course. The use of additive technologies is one of the clearest examples of how new developments and equipment can significantly improve traditional manufacturing. We will consider what additive technologies are for the metallurgical and machine-building industries. For what purposes it is possible to use selective laser fusion, laser cladding and finally detonation spraying. Which of the world's leading steel companies are already interested in these technologies and how additive technologies can change our future. At the end of the course you will be able to: • Additive technologies: what is it? • Applications of additive technologies in mechanical engineering; • Applications of additive technologies in metallurgy; • Prototyping: value and functions; • Application of selective laser fusion in mechanical engineering; • Powder materials for SLM technology; • Gas-thermal spraying of functional coatings; • Detonation spraying application in metallurgy and mechanical engineering; • Microstructure and properties of coatings produced by detonation spraying; • Restoration of parts and accessories with laser cladding; • The areas of application of complex shape products obtained by direct laser; • The areas of application of complex shape products obtained by Direct Metal Deposition; • Microstructure and properties during Direct Metal Deposition...



Covers the most predominant additive technologies currently in use for both product growth and surface coatings. An interrelated course on topological optimization would be useful.


Everything was explained clearly with the help of examples. The course was quite informative as well. It will definitely help me in future.

El curso presenta excelente información pero las clases son solo alguien leyendo un guion, por lo que le falta mas desarrollo para hacerlo más llamativo.

The session was very informative. Could have made more enthusiastic among students.

Just good enough to understand additive technologies.

Although the subject was very interesting, the content was very repetitive and not always relevant to the student's understanding of the topic (ex. wasting time with details of very specific testing equipment).

The presenter read exactly what is included in the notes, so there is no point in listening to what he is saying, you can skip directly to the notes. Having said that, the notes did not include any of the images that were shown in the videos, so you are forced to search the video for images related to the notes.

The evaluations were full of situations where multiple answers were asked when only one answer was possible. Some of the questions were related to topics that were only presented in future classes. Additionally, a lot of the questions related to topics that was not relevant to the student's understand of the topic (ex. specific details about specific testing equipment). It is obvious that no one bothered to review the evaluations before putting them out there.

Again, although the subject was interesting and I learned a few things, I have to say that overall this course was a waste of my time.

I had enrolled to this course to understand the basics of AM. I am very disappointed with the course material and tests. Very poor presentation by tutor. Not worth of paying for certificate.
