摘　　要：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 constructive 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 creative 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 possibilities 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 an
