3D PRINTING

A REVOLUTION IN THE CONSTRUCTION INDUSTRY

WHAT IS 3D PRINTING AND HOW IS IT

REVOLUTIONISING THE FUTURE OF CON-

STRUCTION?

3D printing, also known as additive manufacturing, is an innovative process

in which three-dimensional structures are built up layer by layer on the

basis of digital models. Unlike traditional manufacturing methods, in which

material is removed or moulded, 3D printing is based on adding material,

one layer at a time. This technology enables a remarkable degree of

flexibility and precision.

3D printing offers revolutionary advantages in the construction industry; it

simplifies complex construction processes, reduces waste and significantly

speeds up project lead times. Using robot-controlled printing systems,

large components or even complete structures can be manufactured at an

impressive speed.

A key advantage of 3D printing is the ability to realise geometrically

sophisticated designs that are often only possible at great expense using

conventional methods.

Innovative furniture created using 3D printing is setting new benchmarks

when it comes to both function and aesthetics. In the gardening and landscaping

sector, 3D printing makes it possible to create unique structures

that are both decorative and functional, and that blend in perfectly with

the natural environment. Artificial coral reefs created using this technology

provide a habitat for marine life and help to preserve biodiversity. When

used in art, detailed sculptures can be created that redefine traditional

manufacturing processes. This technology is revolutionising the way that

we design and live.

REVOLUTIONARY ADVANTAGES

FOR CONSTRUCTION:

Time-saving

A key feature of 3D printing is its high speed. While the construction of

traditional structures often takes weeks or months, 3D printing can produce

entire buildings in a matter of days.

Material efficiency

The layered structure minimises material losses, because the system only

uses the material that is actually required. This reduces the consumption of

raw materials and avoids waste.

Cost reduction

Reduced material consumption, shorter construction times and lower

labour costs contribute to a significant reduction in overall costs.

Sustainability

Many 3D printing processes use sustainable or recyclable materials such

as concrete with additives made from waste or biodegradable components.

This significantly reduces the carbon footprint.

Precision and design freedom

3D printing facilitates the production of highly complex structures that are

difficult or impossible to realise using traditional methods.

Flexibility

Whether detached family homes, modular residential concepts or temporary

structures – 3D printing is suitable for use in a vast range of applications

that can be customised to meet specific needs.

The advantages of 3D printing are widely diverse and are

both economic and ecological in nature.

COMPLEX SHAPES:

3D printing enables the precise production of

a wide variety of shapes.

ORIGINAL HOUSE BUILDING:

In the field of residential construction, 3D printing

allows us to think in an entirely new way.

QUICK, COST-EFFECTIVE, UNIQUE

WIDE-RANGING POSSIBILITIES IN THE CONSTRUCTION

INDUSTRY

The areas of application for 3D printing in the construction industry are highly diverse, ranging from residential

buildings and infrastructure projects to artistic or experimental applications.

Residential construction

3D printing is being increasingly used to create affordable housing

solutions. In particular in regions with a major housing shortage, robust

residential structures can be built quickly and cost-effectively using 3D

printing technologies. Companies around the world are already working

on projects that are revolutionising social housing.

Infrastructure projects

In addition to the construction of buildings, 3D printing is also used for the

production of bridges, support structures and other infrastructural elements.

Thanks to the possibility of printing organic and optimised shapes, bridges

can be created with minimal material requirements and maximum stability.

Modular design

3D printing can play a decisive role in the production of prefabricated

components. These modules are produced in a factory and assembled on

site, which results in a dramatic reduction in the construction time.

THE FUTURE OF CONSTRUCTION LIES IN

ADDITIVE MANUFACTURING, AND IT HAS

ONLY JUST BEGUN.

Customisable designs

3D printing affords architects the freedom to design unique shapes and

structures. From biomorphic façades to individually designed interior

elements – thanks to the technology, it is possible to realise architectural

concepts that were previously only theoretically conceivable.

powerful mixing of the material guarantees a homogeneous consistency,

which in turn ensures optimum adhesion and strength even in complex

construction projects.

The multiC 3D print head

Versatility and precision for limitless

3D printing applications – from 2K

materials to 3 mm grain.

Particularly light, yet powerful

One of the main advantages of our 3D print head is its low weight

of just 15 kg. This not only facilitates its integration into existing robot-controlled

systems, but also ensures a high degree of user-friendliness

and flexibility in use. Thanks to the robust design, the print head

is guaranteed to deliver consistently high performance even under

challenging conditions.

Cleaning is quick and easy

Thanks to the sophisticated design with quick-release fasteners and easy dismantling, the

3D print head can be cleaned and maintained quickly and easily. This keeps downtimes

to a minimum and increases efficiency during operation. The quick cleaning option is

another advantage for industrial applications where time is a critical resource. A special

non-stick coating in the mixing area ensures less residue.

Thanks to these unique features, the Knauf PFT multiC 3D print

head is the ideal choice for companies looking for innovative

and reliable additive manufacturing solutions. Together with

APPLICATIONS IN THE

LARGE VOLUME RANGE

The PFT SILOMAX 3D print is a machine solution that revolutionises the production

of large-volume structures such as houses, bridges and ceilings.

The PFT SILOMAX 3D print is a continuously

operating mixing and delivery pump for use

with 3D concrete printers.

The PFT SILOMAX 3D print conveys any machine-compatible, 3D-printable

mortar or concrete (up to 8 mm grain size) from silos/containers fully automatically.

After the water has been added to the mixing tube, the material

enters the collection tank of the delivery pump via a horizontally mounted

mixer with its own drive and is pumped from there to the processing plant

at a rate of up to 30 l/min.

With its impressive precision and speed, the system offers an ideal solution

for the challenges of modern construction projects. The ability to

print complex designs directly from digital models reduces the need

for manual steps and therefore saves valuable time.

An impressive advantage of the 3D printing process is the

significant weight reduction, which is achieved through the

targeted placement of material. This enables the production of

lightweight yet stable components that are ideal for bridges

or ceilings with high structural requirements. At the same

time, the construction time is dramatically reduced thanks to

the efficient combination of material conveying and rapid

production.

Be it in residential construction or infrastructure projects

– the PFT SILOMAX 3D print opens up entirely new

horizons for sustainable, cost-efficient and future-orientated

construction processes.
