HISTORY SUCCESS SECRET
СЕКРЕТ УСПЕХА
As if a kind of relay race through many decades, Russian technicians carried the idea Technology reducing the
of the Tsar Bell - the idea of a record casting. The Tsar Bell was cast for the first time under
Boris Godunov. His weight then amounted to more than 2,100 pounds. During the fire in the cost of metal 3D printing by
Kremlin, the bell broke. Tsar Alexei Mikhailovich summoned craftsmen from Austria to cast a
new, even larger, eight-thousand-pound bell. They asked him for a five-year period because, nine times was created in
they said, these works were "very large and innumerable". Then a Russian master, whose
name, unfortunately, has not survived, came to the tsar and undertook to complete the work in Samara
a year. He kept his word by really casting a bell weighing 8,000 pounds!
Castings of this size were not known to the technician. Sergei Repin, a student at the Korolev University of Samara,

the market (they weigh from one to three tons). For greater
portability, the RepInHeat 3D design has been made modular,
the report says.

two to three times lower than the average market price
of printers of the same class. Another distinguishing
feature of the Samara printer is a relatively high degree
of operational safety, which reduces the requirements
for the working space.
Repin also said that the technology he developed
is compatible with most CNC machines so they can
be converted to 3D printers by equipping them with
RepInHeat 3D print heads. This will significantly
reduce the cost of the development implementation,
the student concluded.
