Education and training at LTH (Lund, Sweden)
In November 2019, the INEX-ADAM project held a two week design for additive manufacturing (DfAM) course at Lund University in Sweden for three researchers from UNIZAG FSB. The course included a mix of both theoretical content and hands-on content in which the attendees designed and printed parts using additive manufacturing processes for metals and polymers. The course content covered general design methodologies for AM and introduced the participants to various analysis, optimization and build preparation software. This included software for topology optimisation and generative design, as well as an in-depth understanding of the advantages of AM, and when to use AM over conventional manufacturing. As AM can be a slow and expensive technology if not used in the correct way, and for the right reasons, the course also covered the economic side of AM, and techniques such as light-weighting which can be used to both decrease product cost, as well as improving functionality.
The participants were also introduced to the use of 3D-scanning and undertook a mass-customisation exercise in which they designed and printed the custom products they designed using selective laser sintering. An in-depth session on designing for metal AM went deep into many theoretical aspects of the implications of design decisions in metal AM, and included an exercise in which the attendees designed parts which optimized for minimum print time, and minimum support material. The attendees then printed these parts in aluminium and undertook all the post processing of the parts including the removal of support material.
All the learning objectives set out by the course were achieved. These objectives included:
- to be able to understand and use relevant design methods for AM
- to learn the use of software and equipment for DfAM
- to optimise, analyse and prepare for build and design in AM
- to optimise, analyse and qualify post processing techniques for building parts in AM
