Abstract
The thesis is to develop a 3D printer that easily and conveniently can print with
recycled plastic such as PET bottles, plastic packaging and much more. The
printer will be designed according to the needs of a developing country. The idea
is not to create an additive manufacturing factory but an effective manufacturing
tool for the locals in the less developed parts of the country. The printer can be
used to manufacture souvenirs, spare parts, kitchen supplies and much more and at
the same time reduce the plastic waste in less economically developed countries
(LEDC).
Most Fused Deposition Modeling (FDM) printers use filament thread as a builder
material. Manufacturing filament is complicated, expensive and energy
consuming.... (More)

Most Fused Deposition Modeling (FDM) printers use filament thread as a builder
material. Manufacturing filament is complicated, expensive and energy
consuming. Developing a 3D-printer that uses granulate/pellets/flakes will
eliminate that process and will make it easier to use recycled plastics.
All the parts of the machine are easy to repair and it is simple to change spare
parts. Practically this means that all the components are easy to find in LEDC or
can be printed using the same printer.
Three prototypes were built and the last prototypes proved that fairly complicated
models could be printed even if it was not performing ideally.
The optimal settings was a printing temperature of 265 C, a print speed of
20mm/s, 0,6mm layer height and fan cooled. (Less)
Popular Abstract
Popular science summary
3D-printing with recycled plastics
Plastic consumption has increased twentyfold in the last half-century and is expected to
double the next 20 years. This increase leads to pollution and intoxication of our oceans and
environment. 95% of the value of plastic materials goes to waste and an alarming 32%
escapes into the our oceans and other ecosystems.
The people mostly affected by this is not the main consumer but the people living in
developing countries. To this day there are about four billion people with an average daily
salary of 4 USD (34SEK). These people are in the base of the world economy called “base
of the pyramid” (BoP). The income varies and is very unpredictable. Many of these people
have low... (More)

The people mostly affected by this is not the main consumer but the people living in

salary of 4 USD (34SEK). These people are in the base of the world economy called “base
of the pyramid” (BoP). The income varies and is very unpredictable. Many of these people
have low or no formal education and have limited communication and distribution channels.
Developing a 3D printer that easily and conveniently can print with recycled plastic such as
PET bottles and plastic packaging will encourage the locals to recycle and find a value in the
waste plastic. The printer will be designed according to the needs of a developing country.
The idea is not to create an additive manufacturing factory but an effective manufacturing
tool for the locals in the less developed parts of the country.
The printer can be used to print souvenirs, spare parts, kitchen supplies and much more and

printers use filament thread as a builder material. Manufacturing filament is complicated,
expensive and energy consuming.

encourage entrepreneurship in the base of the pyramid. (Less)
