Abstract
This document specifies quality assurance requirements for additive construction (AC) concerning building and construction projects in which additive manufacturing techniques are used for construction. The requirements are independent of the material(s) and process category used.This document does not apply to metals.This document specifies the criteria for additive construction processes, quality-relevant characteristics, and factors along AC system operations. It further specifies activities and sequences within an AC cell (additive construction site) and project.This document applies to all additive manufacturing technologies in building and construction (load bearing and non-load bearing), structural and infrastructure building elements for residential and commercial applications and follows an approach oriented to the process.This document does not cover environmental, health and safety aspects that apply to printing facility setup, material handling, operating of robotic equipment, and packing of equipment and/or elements for shipping but material supplier guidelines, robotic solution operating guidelines, and local and regional requirements are applicable.This document does not cover design approvals, material properties characterization and testing.
建筑行業(yè)在勞動力短缺、項目延誤、交付周期增加、材料過度使用、大量廢棄物和不利的碳足跡影響等方面越來越面臨挑戰(zhàn)。此外，從市場的角度看，全球建筑需求不斷增加，特別是在住房危機持續(xù)存在的情況下，基礎(chǔ)設(shè)施項目（無論是新建還是維護現(xiàn)有結(jié)構(gòu)）也在增加。增材建筑（AC），也被稱為建筑用增材制造（AMC）和（3DCP），有望直接解決這些問題。
最近，增材建筑取得了巨大的進展。3D打印的構(gòu)件有望在耐用性、可持續(xù)性、環(huán)保性、成本（大規(guī)模生產(chǎn)時）、交付速度等方面比傳統(tǒng)建筑方法更具優(yōu)勢。然而，如果沒有增材建筑的標準，審批、認證和風險緩解將無法實現(xiàn)。
本文件的目的是概述作為建筑行業(yè)增材制造結(jié)構(gòu)（住宅或基礎(chǔ)設(shè)施）生產(chǎn)和交付的基礎(chǔ)的要求。
增材建筑AC過程的重要步驟已被明確規(guī)定。這些步驟將受到控制和監(jiān)測，以確保用于原位打印和工廠內(nèi)預(yù)制打印結(jié)構(gòu)的高質(zhì)量。本文件不打算針對特定技術(shù)或材料，因此，根據(jù)采用的方法，可以應(yīng)用子過程。然而，應(yīng)注意，3D打印的構(gòu)件應(yīng)該得到當?shù)卣J證工程師的批準，并符合當?shù)睾偷貐^(qū)的規(guī)格和要求。
