ISO and ASTM have collectively outlined requirements for additive manufacturing in building. Credit score: Adobe Inventory
Robotic arms and additive manufacturing are altering how supplies are dealt with and the way buildings are constructed. Nevertheless, as robots enter new environments and tackle new duties, the necessity grows for builders, integrators, and finish customers to pay attention to high quality and security necessities. The Worldwide Group for Standardization, or ISO, has posted paperwork to assist them meet these necessities.
Normal defines secure design for industrial finish effectors
An instance of related industrial requirements, ISO/TR 20218-1:2018 offers steering on the secure design and integration of finish effectors for robots. It additionally provides to ISO 10218-2:2011 on how one can combine robots.
The doc covers collaborative robotic purposes, the place robots share workspace with folks.
“In such collaborative purposes, the end-effector design is of main significance, significantly traits reminiscent of shapes, surfaces and software operate (e.g. clamping forces, residual materials era, temperature),” wrote ISO.
It emphasised the significance of conducting security assessments. Even when robots are marketed as collaborative, their payloads or movement will not be.
Security incidents are uncommon, however events ought to do their due diligence when growing and deploying robots, famous Aaron Prather, director of robotics and autonomous programs at ASTM Worldwide.
ISO and ASTM publish first joint normal for AC
Introduced this week, ISO/ASTM 52939:2023 specifies qualification rules for structural and infrastructure parts in additive manufacturing for building. It offers standards for additive building (AC) processes, high quality, and components for system operations, in addition to processes on a web site.
The brand new normal applies to all additive manufacturing applied sciences in constructing and building of load bearing and non-load bearing constructions, in addition to structural parts for residential and business purposes. It doesn’t cowl metals, materials properties, operational security, packaging of kit and supplies, or tips for working particular robots.
ISO/ASTM 52939:2023 is the primary collectively revealed normal from ISO and ASTM Worldwide, mentioned Prather. Requirements our bodies sometimes give attention to totally different applied sciences, purposes, and industries, however international cooperation can enhance employee security, product high quality, and regulatory environments, he famous.
“This addresses shifting from conventional building requirements and bridging over to additive,” Prather advised The Robotic Report. “[It could be] step one on many to return.”
“This normal additionally units the premise for the approaching building robotic requirements which are within the works throughout quite a few organizations,” he added.
The usual is voluntary, and builders should observe native and regional necessities, famous ISO. In October, ASTM Worldwide introduced a roadmap for digitalization of the development business, sponsored by the Nationwide Institute of Science and Expertise (NIST).

Additive manufacturing altering building
A number of corporations have demonstrated the potential of additive manufacturing for production-grade parts and 3D-printed buildings, together with ABB, Department Expertise, HS2, ICON Expertise, Mighty Buildings, and SQ4D.
These programs typically mix concrete extruders with gantry robots or industrial robotic arms. There has additionally been analysis into utilizing drones for restore of difficult-to-reach constructions, and NASA performed a 3D-printed habitat problem in 2019.
Attainable benefits embrace stronger and distinctive architectures, much less waste of supplies, and even discount in carbon emissions, based on analysis studies from Palgrave Macmillan and Frontiers Media. The worldwide marketplace for 3D printing programs in building is modest however might improve from $13.38 million in 2023 to $22.63 million by 2030 at a compound annual development fee (CAGR) of seven.8%, predicted Advantage Market Analysis.
