additive manufacturing
less energy as it only requires
the energy needed to heat the
printing material and operate
the printer, thus further reducing
the environmental impact
of manufacturing.
Localised production
Shipping raw materials and
finished products across long
distances tend to be energy-intensive
and high-emission
activities. 3D printing allows
products to be created on-site,
eliminating the need for transportation
and reducing the carbon
footprint of these products.
This is particularly beneficial
for small-scale production, as
it allows businesses to produce
goods locally and on-demand.
Customisation and
personalisation
Creating a large number of
identical products, even if there
is no demand for them, is common
practice. This can lead to
excess inventory and waste,
as well as higher energy consumption
and carbon emissions.
Using 3D printing allows
for the creation of unique, customised
products that are tailored
to individual preferences,
creating no excess inventory or
waste. In addition, the ability to
create replacement parts for
existing products through 3D
printing extends the lifespan
of products, reducing the need
for new purchases and further
contributing to sustainability.
Recycling and
repurposing
Finally, 3D printing is sustainable
because it enables the
recycling and repurposing of
materials. Many 3D printers
can use recycled plastic or
metal, materials which reduce
the need for virgin materials
and minimises the environmental
impact.
Additionally, due to the ability
to print very complex geometries,
designers can create
parts that require no screws
nor adhesives and that are
designed to be disassembled
and recycled at the end of their
useful life.
Plastic Recycling Solutions are Giving New
Life to Waste.
Axens provides advanced recycling technologies
to complement and overcome the
limitations of traditional mechanical recycling.
Rewind® Technologies address a variety of
mixed plastics waste feedstock comprising a
large range of polymers, while achieving the
highest quality approved for food consumption
and health care applications.

The right material
A materials strategist's first focus
is always on choosing the
right material, as this is key to
achieving a successful product.
Obviously, if the printed object
is a concept sketch or a prototype,
it rarely matters. However,
for serial production and commercial
products, it is crucial
to first carefully select the material,
immediately followed by
determining the printing technology
to be used. Among the
materials for 3D printing that
are considered sustainable are
those that have already been
recycled and are renewably
sourced or biodegradable. Here
are some examples:
* PLA (Polylactic Acid): a
bio-based plastic derived from
natural resources such as cornstarch
or sugarcane. Certain
grades are biodegradable. It is
one of the most popular materials
for 3D printing because it
is easy to print and produces
high-quality prints. Among the
many providers of this material
are 3D-Fuel, ColorFabb, Filamentive,
and Protopasta.
* Hemp-based filaments:
these are made from hemp
fibres mixed with a binding
agent. Hemp is a fast-growing
plant that requires less water
and fewer pesticides than other
crops, making it an eco-friendly
option. Companies that procontinued
