Abstract(s)
Recent years are showing a rapid adoption of digital manufacturing techniques to
the construction industry, with a focus on additive manufacturing. Although 3D printing for
construction (3DPC) has notably advanced in recent years, publications on the subject are
recent and date a growth in 2019, indicating that it is a promising technology as it enables
greater efficiency with fair consumption of material, minimization of waste generation,
encouraging the construction industrialization and enhancing and accelerating the construc tive process. This new building system not only gives an optimization of the building process
but provides a new approach to the building design materiality. The direct connection between
design and manufacturing allows the reduction in the number of the various construction
phases needed. It is opening a new and wide range of options both formal and chromatic in
customization, avoiding complex formworks, reducing costs and manufacturing time. The cre ative process has a strict and direct link with the constructive process, straightening design
with its materiality. Cement-based materials lead the way, but new alternatives are being
explored to further reduce its carbon footprint. In order to leverage its sustainability and
enhance the system capacity, initiatives are being pursued to allow the reduction of the use
of PC. Geopolimers are taking the first steps in 3DPC. Construction and Demolition Waste
(CDW) materials are used to substitute natural aggregates. Even soil is being explored has a
structural and aesthetic material. These research trends are opening a wider range of possibil ities for architecture and design, broadening the spectrum of color, texture, and formal variations. The concern about textures and colours is not yet evident in many the structures
already printed, opening the opportunity for future research. More can be done in the mixture
and formal design of this building system, “discovering” other raw materials in others waste.
This article aims to make a critical review of technologies, materials and methodologies to sup port the development of new sustainable materials to be used as a plastic element in the
printed structure. A roadmap of 3D printing for construction is presented, and an approach
on mix design, properties in the fresh and hardened state, highlighting the possibilities for ob taining alternative materials are pointed. With this review possible directions are presented to
find solutions to enhance the sustainability of this system discovering “new” materiality for ar chitecture and design.
