Course purpose

This course consists of project assignments (Work-Packages) of 7.5 credit units. The aim is to make sure that the participants have acquired relevant in-depth knowledge in using topology optimization as a design tool for additive manufacturing.

  • General knowledge in setting up simple topology optimal criteria.
  • STL generation/ model transfer.
  • Adaptations for manufacturing with additive manufacturing.

Learning objectives and syllabus

Valid for all Tracks courses:

  • critically and creatively identify and/or formulate advanced architectural or engineering problems
  • master problems with open solutions spaces which includes to be able to handle uncertainties and limited information.
  • lead and participate in the development of new products, processes and systems using a holistic approach by following a design process and/or a systematic development process.
  • work in multidisciplinary teams and collaborate in teams with different compositions
  • show insights about cultural differences and to be able to work sensitively with them.
  • show insights about and deal with the impact of architecture and/or engineering solutions in a global, economic, environment and societal context.
  • identify ethical aspects and discuss and judge their consequences in relation to the specific problem
  • orally and in writing explain and discuss information, problems, methods, design/development processes and solutions
  • fulfill project specific learning outcomes
Course specific:
  • Present an application specific approach to DfAM
  • Adapt design concepts for the respective metal AM technology (LB-PBF or EB-PBF)
  • Screen and choose an adequate metal AM technology (LB-PBF or EB-PBF) for manufacturing the developed part, including design limitations/opportunities and cost evaluation
  • Work collaboratively within a multi-disciplinary group
  • Describe and understand the basic principles for topology optimization.
  • Choosing and implementing optimal criteria methods for various situations of potential importance in practical engineering.
  • Learn to use different software for topology optimization.
  • Describe and understand the basic principles for implementation of topology optimization in additive manufacturing designs.
  • Set up and model simple problems with topology optimization and prepare models for manufacturing with additive manufacturing.

Study plan

 

Examination form

The course consists of three separate Work Packages (WP), each of which is completed in groups. At the end of each WP, every group is required to give a 15-minute presentation and submit a (max) 1,500-word report. Submit simulation files or model from all software’s. Bring a 3D printed model of your simulated results to the presentation.

At the end of the course, each student must submit an individual reflection document, with a maximum of 1,000 words.
