We are the first to invent
a mobile 3D printer capable
of printing buildings from
the inside
english text
Construction can be fast, environmentally friendly and affordable if all the hard work is
done by smart machines.
Mobile 3D printer APIS COR is capable of building a 100 square meters house that is compliant with modern construction standards. Such housing is able to stand for 175 years.
House has even floors and walls — ready to be painted.
No construction waste on building site.
Free selection of wall thickness and configuration.
Building has better insulation properties thanks to air pockets within walls.
House is unaffected by weather conditions due to special mix additives.
Building cost is lower than that of its regular concrete counterpart.
Walls can be additionally insulated with any suitable materials.
Original device is a rotating telescopic manipulator crane 4–8,5 m long and 1,5 m high.
Weight — 2,0 tons.
By staying in one place 3D printer APIS COR can print concrete walls layer by layer.
The main difference of our device from other known construction printers is that APIS COR
printer makes buildings while remaining inside the constructed structure.
Printer has small dimensions so it can easily be transported and doesn’t require long
preparation for the construction works to begin. All preliminary preparations take no
longer than 30 minutes.
With 3D printer any house design can be brought to life. Another advantage is the lack of
construction waste.
4–8,5 m
1. Mobile 3D printer APIS COR with unique software control,
2. Concrete pump with automatic mixing and delivery system,
1,5–3,1 m
3. Silo for storing and transporting dry construction mixture.
Max. operation area
192 m²
Max. height from
a single point
3100 mm
Output of effective area
per 24 hours
100 m²
1 mobile crane for printer transport
8 KW of power consumed by operating printer
Printer has compact dimensions of 5,5×1,5×1,6 m. Weighs 2,0
tons — like a common SUV. These factors make it very convenient
for transportation.
This is as much power as is needed for 5 electrical teapots working
192 m2 printing zone
Printer itself is a rotating manipulator arm that is capable of covering the area from a single point, limited by the size of extendable arm.
To increase the printing zone it’s sufficient to simply move the
printer from one point and start construction in the other.
Automatic horizontal stabilization
Gyroscope and laser rangefinder are used for extrusion head position tracking, PID controller is used for spatial stabilization
30 minutes required for installation and set-up
Thanks to the stabilization system implemented as two active
counterweights it’s possible to install the printer without attaching in on any surface with no need for preliminary site preparation.
All preparations basically include providing power source for the
printer and attaching it to printing mixture supply line: concrete,
geopolymer, fiber concrete.
0 kg construction waste
Printer constructs a building with fiber concrete or geopolymer.
Mixture is supplied in preset doses and with precise timing. Machine prints layer by layer and doesn’t leave any excess waste that
would require cleanup.

Dry construction mixtures, which are delivered to the concrete pump are mixed with a certain amount of water and then are pumped to the printer as a homogenous mix.
With automated mixing and pump system process of printing in executed with machine
precision. Precalculated and stable proportions of components allows to produce a construction mixture with guaranteed quality.
Efficient mixing
Our mixing system allows an excellent mixture quality. It handles
big volumes of material with ease, providing an optimal flow speed
and supply proportions of printing mixture.
Ease of use
The mixer is extremely easy to use. It has a handy panel with comprehensive indication and logical error code display.
Increased durability
Combination of plated and polyurethane components greatly increases mixer durability in comparison with other commercially
available models.
Fast cleaning
Mixer structure includes polyurethane components which, unlike
metallic ones, allow to avoid caking of mixture. By reducing the
amount of sediment on mixer surfaces cleaning procedures require less time and effort.
Silo is used for storage and transport of dry
construction mixtures in big volumes.
Attention! Silo is not included in
our equipment set.
We haven’t included the silo in delivery set
for two reasons:
1. Construction companies may already
have their own silo, so an included silo
can unreasonably increase the price.
2. As the silos are available in different
types and sizes, buyers can choose
one that fits their needs. If you are
not sure what silo to choose, we can
advise you on selecting appropriate
General costs economy per project totals up to 40% in comparison with a regular concrete
building. We offer a pricing per square meter which none of the quality housing construction companies can provide.
Building frame construction — 25%
Logistics — 20-30%
Machine builds a retained framework for a
ferroconcrete base, self bearing walls and
partitions. With ferroconcrete as its core the
building has all the engineering calculations
methods readily available.
By reducing a considerable amount
of additional work there is no need for
extra tools and materials. 3D printing
technology lowers general material
consumption of construction.
Outer and inner finishing — 60%
Roofing — 10%
Machine builds a retained framework for a ferroconcrete base, self bearing walls and partitions.
With ferroconcrete as its core the building has
all the engineering calculations methods readily
We have conducted a series of
tests to make sure that results
of our work are in compliance with
existing certificate standards in
construction industry.
Printer prints walls with machine precision
and makes them even and smooth. Roughing
stage can be skipped straight to final finishing.
Foundation works — 15%
Printer prints a retained framework for foundation, in which reinforcing armatures are installed and heavy concrete is poured
Services — 20%
We plan the layout of electrical junctions, engineering systems
and nodes within the house in advance. Then we upload the
project in the software and get a ready blueprint for laying
down inner services.
What material is used for printing?
For printing process we use a standard mixture of sand and concrete with addition
of polypropylene fiber and dehydrating agent. We also research a possibility of using
geopolymer materials.
Do you need to hard fix the printer to the ground or other structures to
No. Printer includes a stabilization system which uses two active counterweights.
When the printer arm extends in one direction, counterweights move in other direction, keeping the center of gravity at the rotational axis.
Printer can construct walls only? Or can it work with foundation too?
What is the thickness of a single layer and can it be altered?
3D printer can print a retained framework in which armatures and additional connectors are installed, thus making a foundation construction mush easier.
We are printing 2,5×2,5 cm layers. But this can be freely changed using different extrusion nozzles.
Can you print on even surface only?
Can the printed walls be insulated?
Printer includes a special laser system which tracks the surface level so there is no
need to even the ground before printing.
Is there a need to level the printer horizontally?
No. The printer has an automatic stabilization system. Every hydraulic cylinder is
attached to a separate pump with servo control. Positioning precision – 0.1 mm.
Equipment automatically stabilizes horizontally using a precision inclinometer and
PID controller.
Printed walls are insulated in the same way as the ones constructed using foam
concrete blocks. Even without using additional insulation walls have optimal thermal
properties due to their multi-chambered structure.
Can our equipment cut construction costs without affecting the quality?
3D printing technology allows to save overall construction costs by 30-40%. As we
are lowering the price by automating the construction process and minimizing the
human error we can guarantee the quality.
How to move the printer out of the house when construction is finished?
It’s very simple. When not operating the printer is only 1000 mm wide. It can be removed through the door frame using a common pallet truck or be lifted through the
roof before installing floors.
How to print a second floor?
starts at 280 000 $
How to print windows and door frames?
Mobile 3D printer . . . . . . . . . 1
Concrete pump/mixer . . . . 1
Silo is not included in the set
When the frames for doors and windows are printed there are special inserts that are
placed to hold the layers of printed concrete.
Using a crane the printer is lifted up on the first floor. After that the printing process
can continue. The same goes for more stories.
Term of delivery — 6 months starting from100% prepayment
How to enhance the printing quality?
We are constantly working in this direction. We almost have a printer version that is
capable of printing walls with ideal smooth surface. They will not need any additional
works and layers won’t be visible.
What are the reinforcement options?
Machine builds a retained framework for a ferroconcrete base, self bearing walls and
partitions. With ferroconcrete as its core the building has all the engineering calculations methods readily available.
