Abstract
This master thesis describes the process of developing a new polyester filament for
3d-printing. Since the 3d-printing market is growing with makers all over the world
it puts higher demands on the materials. The idea of the filament was a prototyping
material that could produce living hinges. A second field was to visualize how
different infills affect a printed model. The project was a collaboration together with
Perstorp AB at their facility in Perstorp, Sweden.
To develop a new material for FFF-printers (Fused Filament Fabrication), it was
needed to create a product specification. This was done together with the 3d-team
at Perstorp AB and a potential customer. It was an iterative process. Since
polypropylene (PP) is often used... (More)

To develop a new material for FFF-printers (Fused Filament Fabrication), it was
needed to create a product specification. This was done together with the 3d-team
at Perstorp AB and a potential customer. It was an iterative process. Since
polypropylene (PP) is often used when producing living hinges, the material was
called PP-like. The next step of the project was to gain experience in material
compounding and design for additive manufacturing. Then the idea & prototyping
phase started to try to create the material that was searched for, PP-like. The
outcome was satisfying, and the new concept filament was called 850-F. It produced
durable hinges and was printing fast and with good details.
The second part of the thesis was more theoretical to perform an infill study. It was
performed with a material called FacilanTM C8, another polyester filament. This
ended up in a graph showing which amount of infill to choose for a certain strength. (Less)
