This model is translated into code the printer can read, and the printer then deposits materials in layers to create the final object.<\/p>\n\n\n\n<p>This process cuts out many of the complicated &#8211; and human &#8211; elements of manufacturing or construction. Building a house in the conventional manner, for example, can take months, requiring many people from different trades and a multi-layered supply chain.<\/p>\n\n\n\n<p>By contrast, one of the world\u2019s first 3D-printed homes &#8211; <a href=\"https:\/\/www.3dwasp.com\/en\/3d-printed-house-tecla\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">the TECLA House<\/a> &#8211; was built out of local clay in Italy in around 200 hours and using 60 cubic metres of raw material. Its construction required 350 12-millimetre layers. The house was produced in 2021 as a prototype for future buildings that would need to respond to the climate crisis.\u00a0<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong><a href=\"https:\/\/www.climatechangenews.com\/2025\/05\/07\/is-electrification-a-no-brainer-in-the-race-to-net-zero\/\">Is electrification a no-brainer in the race to net-zero?<\/a><\/strong><\/p>\n<\/blockquote>\n\n\n\n<p>In a statement on its launch, Massimo Moretti, founder of WASP, the 3D company behind the project, commented: \u201cTECLA shows that a beautiful, healthy and sustainable home can be built by a machine using on-site materials.\u201d<\/p>\n\n\n\n<p>By using only what is needed in exactly the right place, additive manufacturing greatly reduces waste. Some industry sources claim the difference can be <a href=\"https:\/\/sustainability-directory.com\/question\/what-statistics-indicate-reduced-waste-with-3d-printing\">up to 90%<\/a> less material waste than with traditional methods. The end product can also be designed to be lighter which reduces material use and energy consumption.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Circular by design<\/h2>\n\n\n\n<p>The TECLA House, and similar buildings such as the <a href=\"https:\/\/www.ignant.com\/2016\/09\/16\/the-worlds-first-3d-printed-canal-house\/\">Amsterdam Canal House<\/a>, are sleek examples of what can be achieved with the latest 3D printing technology.<\/p>\n\n\n\n<p>However, they beg the wider question of whether such projects can be made at scale and within budget, while meeting commercial needs. Affordability and custom-made are words that are rarely used in the same sentence.<\/p>\n\n\n\n<p>Signify, a global lighting company, has been tackling this challenge by turning its attention to how 3D printing can support sustainable, mass-made custom lighting solutions.<\/p>\n\n\n\n<p>Signify began experimenting with 3D printers around 2015, primarily for prototyping moulds, fixtures and early product concepts, explained Bart Maeyens, Signify\u2019s global leader for 3D printing.<\/p>\n\n\n\n<p>\u201cThe turning point came when researchers were challenged to explore 3D mass production and succeeded to develop polycarbonate-based formulations able to produce durable end-use parts &#8211; not just prototypes\u00a0&#8211; which enabled full-scale production of luminaires,\u201d he added.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong><a href=\"https:\/\/www.climatechangenews.com\/2025\/03\/14\/neglecting-scope-3-emissions-could-sink-corporate-climate-action\/\">Neglecting \u2018Scope 3\u2019 emissions could sink corporate climate action<\/a><\/strong><\/p>\n<\/blockquote>\n\n\n\n<p>The following year the company launched myCreation, an offshoot that produces on-demand 3D-printed lighting from recycled materials. By 2020, Signify had installed 500 3D printers in hubs around the world, allowing the company to customise lighting at scale.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.pro.mycreation.signify.com\/en-eur\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Signify myCreation <\/a>offers 3D printing as a sustainability-focused product intended to serve the circular economy. All printed parts are produced with at least 65% recycled materials, while bio-circular and industrial recycled plastics are also used, according to Maeyens.<\/p>\n\n\n\n<p>\u201cWe produce on-demand with short production lead times which eradicates obsolete stocks and decimates carbon footprint in production transportation. Rejected parts are recycled\u00a0in-house, leading to zero waste in production,&#8221; he said. <\/p>\n\n\n\n<p>Compared to conventional methods, Signify&#8217;s 3D-printed lighting\u00a0decreases carbon emissions by up to 76% and its products contain up to 40% fewer components, Maeyens noted.<\/p>\n\n\n\n<p>Businesses are responding positively to these possibilities. Food giant McDonald\u2019s and British retailer Marks &amp; Spencer have both signed up to use the 3D-printed products in their stores.\u00a0<\/p>\n\n\n\n<p>The El Dorado International Airport in Colombia installed 9,000 3D-printed lights which, along with retrofitting existing points with LEDs, reportedly reduced the airport\u2019s electricity needs by 65%. A similar project at Madrid Barajas Airport saw a 50% drop in electricity needs.&nbsp;<\/p>\n\n\n\n<div class=\"chn-block block-image\">\n\n    <figure class=\"\" uk-toggle=\"target: #simg-74441\" >\n        <img decoding=\"async\" src=\"https:\/\/www.climatechangenews.com\/wp-content\/files\/2025\/08\/el-dorado-international-airport.png\" srcset=\"https:\/\/www.climatechangenews.com\/wp-content\/files\/2025\/08\/el-dorado-international-airport.png 1000w, https:\/\/www.climatechangenews.com\/wp-content\/files\/2025\/08\/el-dorado-international-airport-960x640.png 960w, https:\/\/www.climatechangenews.com\/wp-content\/files\/2025\/08\/el-dorado-international-airport-480x320.png 480w\" \/>\n        <figcaption>Businesses such as the El Dorado International Airport are starting to see the environmental benefits from 3D printing.

This quiet revolution has been embraced behind factory doors where engineers have grasped its enormous potential.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3D printed renewables and batteries<\/h2>\n\n\n\n<p>The potential is clear when it comes to cutting environmental impact: lighter-weight products, efficient use of materials, local production and high recycling rates.<\/p>\n\n\n\n<p>There are <a href=\"https:\/\/www.theguardian.com\/australia-news\/2024\/mar\/12\/csiro-claims-new-record-for-energy-efficiency-in-lightweight-printed-solar-cells\">already examples<\/a> of 3D-printed solar power cells that can produce renewable electricity without needing to mine and transport heavy materials such as gold or copper over long distances. Wind turbine components, such as blade moulds, are <a href=\"https:\/\/www.ge.com\/news\/reports\/tipping-point-3d-printed-blade-parts-can-help-take-wind-power-to-the-next-level?utm_source=VM_TW&amp;utm_medium=org_social&amp;utm_campaign=us_ge_amproom&amp;utm_term=US_3D_Printed_Blade_Parts&amp;utm_content=Photo_Link_Ad\">being printed<\/a> to cut out wasteful alternatives. These flexible and lightweight blades could potentially capture more of the wind\u2019s energy.<\/p>\n\n\n\n<p>And energy storage &#8211; a key enabler of the energy transition &#8211; <a href=\"https:\/\/energydigital.com\/articles\/the-first-successfully-3d-printed-battery-from-sakuu\">is advancing<\/a> by printing batteries onsite that can increase energy density and improve efficiency. They could also help put an end to environmentally damaging supply chains often associated with battery production.\u00a0\u00a0\u00a0\u00a0\u00a0<\/p>\n\n\n\n<p>These are just a handful of examples where clean tech is taking advantage of the 3D printing revolution. Green industry experts are hoping the next step is to expand the use of these techniques so that the benefits become widespread.<\/p>\n\n\n\n<p><em>Adam Wentworth is a freelance writer based in
