The use of 3D printing for real life objects is often limited to the low amount of
materials that can be used or, in some cases, for the cost of the technology.
Since the advent of Makers, 3D printing processes started to be cheaper and
enthusiasts and researchers began to experiment with them. In the last years the
experimentation process has found a prolific terrain fed by low cost materials
and machinery, and by a vibrant community. This helps the experimentation on
different materials, like ceramics and thermosetting polymers. The possibility to
3D print thermosets materials enabled a whole class of materials to candidate
as 3D printable. A flexible 3D printing process for viscous materials have been
developed, such process could be used to 3D print thermoset resin reinforced
composite materials. It has been demonstrated that recycled composite material
can be 3D printed enabling the recycled material re-manufacturing, following a
circular economy approach. Since the first wind farms constructed in the world
are turning 25 years old, and will soon be decommissioned, the aim of this
research is to build a circular economy path for thermoset recycled fiberglass
reinforced materials in which the 3D printing process creates the added value for
a new class of re-manufactured composites and products. In order to 3D print the
material, the viscosity of the system has been analyzed and the polymerization
process has been studied and optimized. A frugal innovation approach have
been used: low cost 3D printers could be easily modified to 3D print the new
composites, and, thanks to the simplicity of the system, the process could be
scaled up, allowing for bigger volume 3D print. Some proposals regarding the
possibility of using this novel approach for the construction of attractions within
amusement parks have been studied and prototyped.

Andrea Mantelli has completed his Master of Science in
Materials Engineering and Nanotechnology from Politecnico
di Milano with an original work on continuous composite 3D
printing. He has completed his Internship at FabLab London in
2015 where he consolidated his ‘maker’ attitude. Currently he
is working as a Research Fellow at +Lab in the Department of
Chemistry, Materials and Chemical Engineering “Giulio Natta” at
Politecnico di Milano.
