Ecological side effects such as the
production of considerable plastic
waste, its high electrical consumption
and the ongoing technical support
needed to make products that are
more comfortable and, most of all,
healthier for the patients. For instance,
many rural areas are characterized by a
lack of technology and hardware, and
for those living there, 3D printing is
simply not sustainable yet.
