About

You will be able to

  • Explain the additive manufacturing process chain from CAD to finished part
  • Classify AM processes as per ASTM categories
  • Describe SLA, DLP, FDM, LOM, SLS, SLM, EBM and binder jetting
  • Prepare STL files, choose orientation, supports and process parameters
  • Select AM materials and post-processing for a given application
  • Explain AM applications in tooling, medical, aerospace and automotive fields

Who it is for

  • B.Tech Mechanical Engineering students of Semester 7 (AKTU)
  • Students of other universities studying the same subject who want unit-wise coaching

What you need

  • Manufacturing Processes and Computer Aided Design
  • Basic CAD modelling skill

Questions

Which syllabus does the Additive Manufacturing course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Additive Manufacturing. If your own university's syllabus differs, the centre follows your university syllabus.

Will this help in the university examination?

Yes. Teaching is unit-wise as per the AKTU scheme, with numericals, previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Will I get to see a 3D printer?

Yes. FDM printing is demonstrated from STL preparation and slicing to the finished part; other processes are shown with videos and samples.
