Behold the World's Largest 3D Printer

They're calling it "the world's largest 3D printer," but also "the factory of the future" — not just a 3D printer, but a manufacturing system. It's the succcessor to a 3D printer that could create an entire house, cutting construction time and labor, according to the Associated Press. And this one "may one day create entire neighborhoods." It has a voracious appetite, consuming as much as 500 pounds (227 kilograms) of material per hour... The university wants to show how homes can be constructed nearly entirely by a printer with a lower carbon footprint. The buildings and construction sector accounts for roughly 37% of global greenhouse gas emissions, largely due to the production and use of materials such as cement, steel and aluminum that have a significant carbon footprint, according to the United Nations Environment Programme. Such printed buildings can be recycled, which is unique compared to current construction. "You can basically deconstruct it, you can grind it up if you wish, the 3D printed parts, and reprint with them, do it again," Dagher said before the event... But it can be used for a variety of other creations and already has been used for a range of things, from boats to defense department structures. The project is partly funded by the U.S. military, according to the BBC. "Maine University says it hopes the printer can be used to make affordable housing, as well as bridges, boats and wind turbines."

Trudeau Pushes 3D-Printed Homes To Solve Canada Housing Crisis

An anonymous reader quotes a report from the Daily Hive: It is now the third consecutive day a major housing funding announcement has been made by Prime Minister Justin Trudeau. Friday's announcement entails over $600 million in investments targeted to help lower the construction cost of homes and speed up building timelines, with a new focus on creating new building innovation technologies. This includes a new $50 million Homebuilding Technology and Innovation Fund, which the federal government aims to leverage an additional $150 million from the private sector and other levels of government. Another $50 million will be invested in ideas and technology such as prefabricated housing factories, mass timber production, panelization, 3D printing, and pre-approved home design catalogues -- specifically projects already funded. As well, $11.6 million will go towards the federal government's previously announced Housing Design Catalogue to create a standardized home structure design for simplicity as well as construction and cost efficiencies. The vast majority of today's announced funding will go into the federal Apartment Construction Loan Program, which provides low-cost financing to support new rental housing projects using innovative construction techniques from prefabricated and modular housing manufacturers as well as other homebuilders. Prime Minister Justin Trudeau said in a statement: "We're changing the way we build homes in Canada. In Budget 2024, we're supporting a new approach to construction, with a focus on innovation and technology. This will make it easier and more cost-effective to build more homes, faster. You should be able to live in the community you love, at a price you can afford."

Your Next Pair of Walmart Pants Could Be 3D Woven

An anonymous reader quotes a report from Wired: We've been ableto design and 3D-print plastic phone cases and toys at home for a decade now. For almost every other consumer product made in a factory, the robots have taken over the heavy lifting. But fashion is still stuck in the 20th century. Take a typical pair of chinos. Cotton threads are woven on a large loom at a mill somewhere in Asia, then shipped to a dye house, then shipped (usually a great distance) to a garment factory somewhere else in Asia. There, the fabric is laid flat and cut into shapes, with the excess fabric being landfilled, incinerated, or (very rarely) recycled. Underpaid and exploited garment workers hand-sew those pieces of fabric into pants, which are then shipped across the ocean to a fulfillment warehouse or a store near you. This global apparel supply chain is inefficient and emissions-heavy -- an estimated 4 percent of global waste and 2 to 4 percent of greenhouse gas emissions are attributed to fashion production. Brands have to make risky predictions many months in advance about which items will sell, leading them to over order on a massive scale. Now, Walmart is piloting a project with the San Francisco Bay area startup Unspun to test whether it can manufacture the retailer's in-house brand of chinos in the US using a technology called 3D weaving. The experiment is part of a push to nearshore Walmart's supply chain and cut down on emissions and waste associated with textile production. While still very much in the prototype phase -- the two companies are exploring how to use Unspun's technology to supply pants to Walmart's stores -- if successful, this project could upend the way apparel is manufactured on a huge scale. Unspun hopes to eventually deploy 3D weaving micro-factories throughout the United States, so that anyone can order custom and locally made apparel on demand.
