# Specification-Grade 3D-Printed Luminaries OCL's Printz Line Includes the Cosma Ola and Hela Models By Colin Smith | Written with AI assistance | Published 2026-03-23 | Business Source: Trend Hunter, https://www.trendhunter.com/trends/ocl-printz-line References: [3dprint](https://3dprint.com/324417/ocl-architectural-lighting-uses-3d-printing-for-luminaries/)  OCL Architectural Lighting introduced the Printz line, a set of specification-grade [3D-printed luminaries](https://www.trendhunter.com/trends/souffl-lamp) designed for commercial interiors, featuring large material-extrusion shells made with at least 85% recycled content. The collection includes the Cosma, Ola and Hela models and was developed using OCL’s in-house extrusion technology to produce repeatable, [large-diameter fixtures](https://www.trendhunter.com/trends/nishiki). Printz pieces range from 45 to 91 cm in diameter and were engineered for adaptability and customization, letting designers specify shapes, sizes and finishes without traditional tooling. OCL positioned the line for contract markets such as offices, retail and gyms and emphasized manufacturability and scale for architectural projects. For buyers and specifiers, Printz shortens lead times and lowers inventory risk by enabling local, made-to-order production and easier design iteration. The line underscores a broader shift toward [additive manufacturing in high-margin architectural lighting](https://www.trendhunter.com/trends/lighting-innovation) where customization and supply-chain resilience are increasingly valued.
