The Worldwide Group for Standardization (ISO) not too long ago revealed ISO/ASTM 52939:2023.
Titled “Additive manufacturing for development — Qualification rules — Structural and infrastructure components,” this customary goals to make sure high quality, security, and effectivity throughout the 3D printing development trade.
“The aim of this doc is to stipulate the necessities needed as a foundation for manufacturing and supply of top of the range additively manufactured constructions (residential or infrastructure) within the development sector,” the ISO doc said.
The ISO is an impartial professional physique which creates requirements defining technical specs and tips to make sure the constant and quality-controlled utilization of merchandise, companies and programs.
Based in 1947 and headquartered in Geneva, Switzerland, the ISO has now revealed over 24,500 worldwide requirements overlaying a variety of technological and manufacturing processes.
A brand new ISO/ASTM customary for development 3D printing
Printed in December 2023, ISO/ASTM 52939:2023 was ready by a collaboration between the ISO’s Additive Manufacturing Technical Committee (ISO/TC 261), and ASTM Worldwide’s Additive Manufacturing Applied sciences Committee (F42).
The ASTM, previously generally known as the American Society for Testing and Supplies, is a world requirements group primarily based in Pennsylvania, US. The continuing partnership between the ISO and ASTM seeks to determine a typical set of requirements for additive manufacturing.
This newly revealed customary specifies high quality assurance necessities for additive manufacturing in development. In accordance with the ISO, threat mitigation, approval, and certification for Additive development is unattainable with out the required ISO/ASTM requirements. These not too long ago revealed necessities are impartial of fabric, and don’t apply to metals.
The doc specifies the standards for 3D printing development processes, quality-relevant traits, and components related to additive manufacturing development operations. All through the doc, important steps regarding additive development processes are specified. These steps should be managed and monitored by a regionally licensed engineer to make sure high-quality 3D printed constructions.
ISO/ASTM 52939:2023 applies to all additive manufacturing applied sciences utilized in development, and structural and infrastructural constructing components for residential and industrial functions.
Nevertheless, the doc doesn’t apply to environmental, well being and security elements regarding the 3D printing facility setup, materials dealing with, working robotics, or the packing and transport of kit. What’s extra, the brand new customary doesn’t cowl design approvals, materials properties, characterization and testing.
Additive manufacturing and the development trade
In accordance with the not too long ago revealed ISO doc, the development trade is going through a variety of challenges, together with labor shortages, undertaking delays, rising lead instances, materials wastage, and extreme Co2 use.
What’s extra, international development demand is reportedly escalating as the worldwide housing disaster continues, and infrastructure tasks improve in scale. The ISO claims that additive manufacturing has the potential to instantly tackle these challenges.
The usage of additive manufacturing for development has superior over latest years. 3D printing can show to be a extra sturdy, sustainable, cost-effective, and environment friendly various to conventional development strategies.
Earlier this yr, CyBe Development, and the South African Housing & Infrastructure Fund (SAHIF) introduced a partnership to handle South Africa’s acute housing scarcity. Leveraging concrete 3D printing expertise, these two organizations intention to ship sustainable and inexpensive properties in a nation with a backlog of two.3 million inexpensive properties.
Elsewhere, Development 3D printing firm Mighty Buildings not too long ago raised $52 million in funding to broaden the manufacturing of 3D printed homes. This funding spherical was led by Wa’ed Ventures, a enterprise capital fund supported by Saudi Aramco, and US-based enterprise agency BOLD Capital Companions.
These funds can be utilized to hasten the manufacturing of recent properties to fulfill rising demand throughout the US. Funding may also be leveraged to determine additive manufacturing services in Saudi Arabia and the United Arab Emirates (UAE), two of the most important and quickest rising development markets on the earth.
