• Know the latest achievements in the field of additive manufacturing, high-temperature compounds, coatings.

Learning outcome: applying knowledge and understanding

• To use knowledge and skill in practical professional activity in the selection, justification and development of technological processes of additive manufacturing.

Learning outcome: formation of judgments

• Formulate, present the results of the research, making their own conclusions, prove their own theses in a reasoned manner.

Learning outcome: communicative abilities

• Effectively work individually, as a team member on interdisciplinary topics, as well as lead a team.

Learning outcome: learning skills or learning abilities

• Possess the skills of identification, formulation and solution of engineering tasks of professional activity.

Teaching methods

In practical classes, scientific methods are used to find justifications for the mechanism of the results obtained and to resolve physical contradictions

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

The evaluating policy of learning outcomes by work type

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

• 40% of the examination result;
• 60% of current control result.

The final grade is calculated by the formula:

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
