On the sidelines of its participation in Expo 2020 Dubai, the Czech Republic's pavilion displays a gold-plated model of Masjid al-Haram in Mecca.
The model was invented by "IQS nano" and implement by 3D printing technology.
This miniature model broke records in this field, with a size of 820µm x 643µm x 135µm, i.e. with the simplicity of a sewing needle. It was printed using micro lithography with a resolution of 250nm, which has approximately a scale of 1 : 600,000 from the reality of Masjid al-Haram in Mecca.
The company produced this model for its first display in the world at Expo 2020 Dubai, where the silicon model was created using 3D nanoprinting based on lithography; it was coated with an extremely thin layer of gold (100 nanometers thick). Only 10 pieces of this model are available.
"In the pavilion we are opening a rotating exhibition of Czech treasures, and we will display the model from December 15 to January 31, 2022. IQS nano has been developing 3D nanoprinting since its inception 10 years ago," Peter Frank, the managing director of the company said.
