Brandenburg Gate on the micrometer scale in comparison to a 1 ct coin.
The Brandenburg Gate is not only
one of the most important sights of
Berlin. Since the Fall of the Wall on 9th
of November 1989, Brandenburg Gate
has become one of the most wellknown landmarks of Germany.
RAPID PROTOTYPING
We use our technical possibility and
artistic design freedom to commemorate the 25th anniversary of this
historic event. This miniature measures
2.5 mm in length and 1 mm in height,
corresponding to a scale of 1:26,000 in
compare to its original in Berlin.
Since the introduction of the Euro as
currency, one can find the Brandenburg Gate on several German cent
coins, such as shown for comparison
reasons on the image above.
Nanoscribe´s outstanding techno­logy
of Dip-in Laser Lithography (DiLL) in
combination with the ­
upgradable
ultrafast galvo-scanning module GT
allow for 3D printing in unprecedented
quality and speed – now even of
objects on the mesoscale.
Impressive dimensions: The original
Brandenburg Gate has got a length of
65 meters and a height of 26 meters, the
miniature is printed in scale 1:26,000.

(Tiemo Bückmann) 3D galvo-scanner dip-in direct-laser-writing optical lithography using Nanoscribe´s
­Photonic Professional GT system
allowed for the fabrication of mechanical metamaterial architectures with
deep submicron features yet cubic millimeter overall volumes at the same
time. Using these we have designed,
fabricated and characterized polymeric
core-shell elastostatic unfeelability
cloaks composed of as many as 1024
extended face-centered cubic unit
cells. The high precision of the fabrication was needed to adjust the mechanical properties of the surrounding and
the cloaking shell to guide the forces
around and let the solid cylinder vanish
from being felt.
On the other hand the millimeter scale
overall volume was essential to characterize the cloak optically and get in
reach of possible applications.

ONCE UPON A TIME
It is like in Hans-Christian Andersen’s
fairy tale about the princess and the
pea. The princess feels the pea in spite
of the mattresses. When using the
cloak, however, one mattress would
be sufficient for the princess to sleep
well. The cloak shows that mechanical metamaterials are a growing field
using direct laser writing as only here
the true three dimensionality and
interesting size scales can be covered
opening the door for interesting applications.

To date, cloaking has been demonstrated experimentally in many fields
of research, including electrodynamics at microwave frequencies, optics,
static electric conduction, acoustics,
fluid dynamics, thermodynamics and
quasi two-dimensional solid mechanics.
The results are now presented in the
Nature Communications journal.

(Yann Tanguy, Fabian Niesler) While
known for its outstanding 3D printing
capabilities, the Photonic Professional
GT also enables high-resolution 2D
patterning of thin films, called maskless lithography.
The technology of direct laser writing
(DLW) complements 2D manufacturing technologies available on the
market and represents an alternative
to traditional electron-beam lithography (EBL) and photolithography technologies offering similar performance
levels. In terms of spatial resolution, a
recent publication [1] positions DLW
between these two technologies,
while the patterning speed is now
approaching EBL standards thanks to
the implementation of galvanometric
mirror scanners. 2D photoresist structuring using a DLW approach does not
require expensive masks which makes
it an ideal tool for all aspects of prototyping applications as well as fabrication of masters.
HIGHEST RESOLUTION
The underlying principle of two-photon absorption combines high resolution patterning together with a broad
range of compatible UV sensitive photoresists. Structures with high-aspect
ratios can be achieved without limitations from Beer’s absorption law or
electron scattering effects. Along the
list of compatible negative-tone photoresists are SU-8 as well as Nanoscribe’s
Checkerboard arrangement of test patterns fabricated in positive-tone resist AZ® 5214 on 4 inch
silicon wafer.
IP resins that provide robust and
reliable process results.
Nanoscribe has recently evaluated
the performance of the Photonic Professional GT for 2D patterning of various thin- and thick-film positive tone
resists of the AZ® series [2] (AZ® 9260,
AZ® 5214E, AZ® MIR 701, AZ® 40XT)
on glass and silicon substrates. These
resists and substrates cover a broad
range of application fields, e.g. etch
masks, sputter masks, high-aspect
ratio structures and electro-plating
templates.
