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.

Videos could be more engaging and fun to watch. A list of definitions at the end would be helpful.

Just good enough to understand additive technologies.

T​he course is very lacking in content, and specially in the way it is presented to the learner. Videos are just readings of the reading material, while on the other hand readings don't include any kind of visual aids for explanations on systems or processes. The practice and graded quizzes are badly made, asking questions not yet viewed in the content or straight up relying on tricky and bad wording to confuse the learner rather than actually improving on what was explained on the lectures. All feedback given isn't helpful at all, since it is either "Correct. You were attentive to class" or "Incorrect. Repeat topic". No further explanation on an answer is given, which having taken other courses on the site, makes me specially angry on the overall quality of the course.

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.
