Pieces are produced with binder jetting. Originally
developed in the early 1990s, binder jetting stands
out from other 3D printing methods by using a
liquid binding agent selectively deposited onto a
powder bed to form a solid part. This process is
then repeated layer by layer until the entire object
is formed. Unlike fusion-based technologies, binder
jetting does not require heat to bond the material,
offering distinct advantages such as reduced
energy consumption and faster build times,
allowing the use materials such as sand, metal and
ceramics.
In this project, we focused primarily on quartz
sand with a density of 2.65 g/cm³ and an average
grain size of 140 μm. Quartz sand has been
widely used in industrial applications like molding
due to its thermal and mechanical properties.
However, its use in creative or lifestyle products
remains relatively uncommon despite the obvious
advantage of having enhanced durability and less
structural constraint on the design.
With quartz sand, we were able to produce pieces
suitable for both indoor and outdoor conditions,
with a unique aesthetic characteristic due to the
special texture of the sand
