The castle on a pencil tip
When we talked about high-resolution 3D printing, one question came up repeatedly: how does UpNano define high resolution?
At TU Wien we have developed a simple and vivid answer to that:
Take a pencil
And 3D print a castle on its tip
With UpNano's high-resolution printing system NanoOne you can print your own castle on a pencil tip. The system achieves a spatial resolution down to a nanometer level.
The two towers of the castle fascinate at first sight
The pillars of the right spire have a diameter of 950 nm and are thus a 100 times thinner than a human hair. Hard to believe, but despite this fineness the pillars are perfectly straight and fulfil their weight-bearing function.
You will only believe it when you have seen it
The mini-castle has a dimension of 230x250x360 µm and was printed in less than six minutes. Have a look at the YouTube video explaining the fabrication of the castle by 2-photon lithography.
From the sketch to implementation
The design of the castle on a pencil tip was created by Daniela Mitterberger and Tiziano Derme from the design studio MäID in Graz. Their ambition was to reinterpret the Sutyagin House in nanoscale – the residence of the local crime lord Nikolai Petrovich Sutyagin and his family in Arkhangelsk, Russia. The 44-meter-tall building was considered the highest wooden building in the world, or at least in Russia. The building was declared a fire hazard, and following a court order the house was demolished in 2008.
