segments over the coming years and has considerable potential. Other residential
printing projects are now being drawn up in Germany. We are proud that PERI's
involvement in the project in Beckum has seen us become a pioneer and forerunner
for this new construction technique."

"At PERI, we see ourselves as a leading innovator in our markets," says Dr
Fabian Kracht, Finance & Organisation Director and Spokesperson of the PERI
Group management board. "Investing wisely in start-ups that are offering new
solutions in our markets is another aspect of that. 3D printing is a business
segment that has emerged from this investment portfolio and has now made its way
onto the market. The success story in Beckum is validation that we have taken
the right approach."

"3D construction printing fundamentally changes the way we build and the process
of residential construction. As this is the first building of its kind, we are
making a point of printing at a slower rate than what is actually possible,"
says Leonhard Braig, Production & Supply Chain Director at PERI GmbH. "We want
to take the opportunity to gain further experience in day-to-day operations as
this will help us to leverage the cost reduction potential of our technology to
a greater extent in the next printing project."

The building was planned by MENSE-KORTE ingenieure+architekten and the client is
Hous3Druck GmbH. "The concrete printing process affords us designers a high
degree of freedom when we are designing buildings. With conventional
construction methods, this would only be possible at great financial cost," says
architect Waldemar Korte, partner of the architectural practice MENSE-KORTE
ingenieure+architekten in Beckum. "With our printed residential building in
Beckum, we are demonstrating the potential of the construction printing process.
It is a huge privilege for our team to realise the first 3D-printed residential
construction project in Germany. We believe in the future viability of
construction printing technology for the construction sector and already have
other 3D printing projects on our radar."

Printing technology and materials

PERI uses 3D printers of type BOD2 for printing. This printing technology comes
from the Danish manufacturer COBOD. PERI acquired a stake in COBOD back in 2018.
The BOD2 printer used in Beckum is a gantry printer, which means that the print
head moves about 3 axes on a securely installed metallic frame. The benefit here
is that the printer can move along its frame to any position within the
construction and only needs to be calibrated once.

The "i.tech® 3D"material used in the printing process was developed by
