Objet 3d’art


ack in the olden days, people
used to listen to music on
flat plastic discs covered
in tiny grooves. A needle
on the end of an arm would
bounce around in these tiny grooves as the
disc span, and the vibration was amplified
electronically to produce music. It was the
best of times, it was the worst of times.
Amanda Ghassaei used a UV-cured
resin printer called the Objet Connex500,
which has a resolution of 600 dpi in the x
and y axis, and 16 microns in the z axis to
create a playable record (a film of WD-
is about 17 microns deep). Despite that,
the grooves on the 3D-printed record are
about ten times deeper and ten times wider
than those on a pressed vinyl record, so
the 3D-printed record can’t hold anywhere
near as much audio as a pressed record.
Amanda has published a detailed
explanation of using the Python
programming language to extract useful
data from an audio file, turning the data
into an STL file and, from there, into a
printed resin object, along with the ups
and downs of getting the process right.
She’s also released recordings of
3D-printed sample tunes, including Nirvana’s
Smells like Teen Spirit, Daft Punk’s Around
the World, Debaser by Pixies, and songs by
Joy Division, New Order, and Aphex Twin.
