Arup and CLS Architetti 3D printing concrete house for Milan Design Week

Architecture firms
 UK, and CLS
, Italy, are 3D printing a concrete
house as part of their
3D Housing 05
project, for this year’s Milan Design

Designed to be disassembled and moved, the house will be
3D printed over the course of a week, on site at Milan’s Piazza
Cesare Beccaria. It will feature a living area, bedroom,
kitchen and bathroom over an area of 100 square meters. The
architects intend the house to be a demonstration of the
maturity of concrete 3D printing for architectural

roof, window frames and doors. Cement is supplied by
a subsidiary of

, both companies form
the world’s second largest supplier of cement.

Last year, CyBe used their
CyBe RC 3D printing arm to construct a 168 meter squared
research facility
for the Dubai Electricity and Water

Arup’s Europe Materials Consulting Lead, Guglielmo Carra,
said “the construction industry is one of the world’s biggest
users of resources and emitters of CO2. We want to bring a
paradigm shift in the way the construction industry operates
and believe that 3D printing technology is critical to making
buildings more sustainable and efficient.”

Arup claims this method of 3D printing wastes fewer
materials and benefits from the ability to produce complex
structures like double curved walls. Using only the materials
required (as the 3D file specifies the exact volume of material
needed) will result in  a lower cost – if everything goes
to plan.

Concrete 3D printing integrating “new, more organic

In an interview with the architectural design
Massimiliano Locatelli of CLS Architetti, said that his
aesthetic vision for concrete 3D printing is “to integrate new,
more organic shapes in the surrounding landscapes or urban
architecture. I wanted to show a different way of using a
printing machine and explore how a concrete house could create
a dialogue with our memories of interior design, made of
references to archetypes of the past”

Luca Stabile, Arup’s Italy Building Practice Leader, said
“We believe 3D printing will contribute to breaking the
conventional barriers in engineering and architecture. The use
of new technologies alongside a new digital approach to the
built environment will be instrumental to creating even more
complex multi-storey 3D printed buildings.”

Elsewhere in the 3D printing construction sector, Siam Cement
 is developing what they call

“Triple ‘S’” 3D concrete
 for the construction of larger
structures. BAM Infrastructure worked with Eindhoven University
of Technology to

3D print an 8 meter concrete bicycle
, also using the CyBe RC concrete 3D
