Sammanfattning
Additive manufacturing (AM) is transforming the design and manufacturing industries
by allowing production of complex geometrical components that enhances
efficiency and performance. However, despite its significant potential, AM poses
several challenges, particularly in achieving cost-effective mass production.
This study focused on interviewing engineers within an aerospace product development
organization to identify the challenges and opportunities related to AM
powder bed development. The responses were analyzed, and the findings were visually
represented using an (Design for additive manufacturing) DfAM AIM diagram.
Additionally a benchmark was performed with the additional industrial partner that
has experienced in this area.
The results from the interviews highlighted several key challenges in the AM design
process and within the organization design practice. Design for additive manufacturing
is a specialist area closely related to specific AM process. The study also
identifies knowledge gaps and lack of communication between people and parts of
organization. Process simulation software is not a standardized platform within the
company, and difficult to use which means that front loading in design is still hard
to perform.
A conclusion is that, the organization needs to undertake several strategic improvements
such as bridging the knowledge gap and improve the communication. Implementing
standardized design guidelines specific to AM will streamline the design
process and reduce reliance on trial-and-error methods. Furthermore, by integrating
advanced simulation tools early in the design phase support structures can be optimized,
and material waste can be reduced, and manufacturing outcome can be more
accurately predicted. This integration will not only improve efficiency but also reduce
costs. Lastly, investing in research and development to refine post-processing
techniques and explore alternative materials could further enhance the economic
viability of AM.
