# Large-Format Additive Printers Evergreen Additive Inc. Launches Large-Format 3D Printer By Debra John | Written with AI assistance | Published 2026-03-24 | Business Source: Trend Hunter, https://www.trendhunter.com/trends/large-format-printers References: [mainebiz.biz](https://mainebiz.biz/article/composite-technology-startups-are-making-it-possible-to-3d-print-large-objects-speed-production/)  [Evergreen Additive Inc.](https://www.trendhunter.com/trends/evergreen-select-rebrands) launched a large-format printers for additive manufacturing service, specifically for maritime tooling and defense components, founded by four researchers from the [University of Maine’s](https://www.trendhunter.com/trends/spee3d-emu) [Advanced Structures and Composites Center](https://www.trendhunter.com/trends/biohome3d). The startup offers production manufacturing, rapid prototyping and consulting, featuring a robotic 3-D printing system capable of handling multi-foot boat molds and components with plans to expand machine size in Q2. The company established operations at Brunswick Landing with an 8,000-square-foot workspace that received electrical and floor upgrades to support continuous production. Initial equipment investment totaled about $1 million, supported by founders and private investors, and the firm won a Defense Innovation Unit award while pursuing additional capital to scale output. Evergreen’s approach aims to cut tooling lead times by 50%–75% for boatbuilders and enable repeated, minimally supervised 24/7 runs, which addresses labor shortages and supply-chain delays.
