The document discusses the SINTAS project which examines the sustainability impact of new technologies on after-sales service supply chains. It provides an agenda for a project meeting that includes introductions, a discussion of activities in the past six months including research, student activities, external meetings and presentations, and a financial report. Progress updates are given for the three work packages focusing on which parts can be 3D printed, the quality and reliability of printed parts, and incorporating AM into maintenance policies. Two student projects studying the effect of moisture on printed part properties and the effect of layer thickness are also outlined. The meeting concludes with planning future student projects and follow up activities.

 Research questions:
1a. What parts can be produced with 3D printing ?
 shape, size, complexity, material: both metal and plastics (?)
1b. What quality can be achieved ?
 shape tolerance, mechanical properties
2a. What is the reliability and durability of typical printed parts ?
 fatigue, wear, corrosion
2b. How sensitive are the printed part properties for
 environmental conditions, operator skills ?
3. How can the effect of AM technology on the selection of an
optimal maintenance policy be incorporated and how can its impact
be quantified?

11. STATUS
