Tiivistelmä
In this thesis, a workflow was designed for filament recycling for the 3D printing laboratory of the Lapland University of Applied Sciences. The goal was to create a circular economy within the laboratory and minimise waste generation, since 3D printing currently causes a lot of excess material. To create a circular economy, a system which produces recycled filament out of 3D printing material was purchased by the niversity. The system consists of a shredding device, a polymer dryer and a filament extrusion system.

The thesis starts with theoretical chapters on the filament production process, recycling issues of different materials and circular economy in 3D printing. Literature research including scientific articles, books and websites was used as a primary method to describe these topics.

In the second section, the actual workflow was created. Research papers as well as websites were used to create the workflow. Additionally, the workflow was tested with the equipment in the laboratory and some information was sourced from the experience gathered throughout the process. The result of the workflow creation were three slightly different workflows, one main workflow, an alternative workflow which used additional material that needs to be purchased and a workflow which creates a near zero-waste circular economy through the recycling of filament spools.
