Company profile

researched Aug 2026

AON3D provides industrial additive manufacturing hardware, software, and materials for producing high performance polymer parts. Its core product line comprises Hylo, a production-ready 3D printer for manufacturing full-scale, end-use parts in high performance polymers including PEEK and ULTEM, and Basis, software that manages the additive manufacturing workflow from model to quality-verified part.

The platform pairs physics-based thermal simulation software, which generates dynamic part-specific print settings, with hardware automation and in-process monitoring built into Hylo. The company states this combination yields repeatable, quality-verified parts up to 85% stronger. AON3D supports an open materials approach, offering preconfigured profiles for third-party material suppliers, composite-ready hardware, and no unlock fees, spanning cost-effective prototyping polymers through aerospace-grade materials.

Targeted applications include manufacturing operations — distributed manufacturing and digital warehousing — and aerospace and defence, where the company cites mechanical strength and mass reduction, including maintenance, repair and overhaul use cases.

Business model

AON3D sells an integrated industrial additive manufacturing platform consisting of 3D printing hardware (Hylo), software (Basis), and support for open, third-party material ecosystems. The company positions its offering as combining the affordability and flexibility of open material systems with the ease of use and repeatability of closed ecosystems, and does not charge upgrade or material unlock fees.

Traction

AON3D cites 300+ clients globally. Customer-reported outcomes include Locomation saving $50,000-$100,000 and months per design iteration by printing end-use sensor housings, and Opterus saving over $4,000 and four to six weeks per high temperature composite mold.

▸Full profile — market position, technology, go-to-market

Market position

AON3D reports more than 300 clients globally and targets industrial users producing end-use parts in high performance polymers.

AON3D differentiates on an open material system that avoids upgrade or unlock fees while aiming for the repeatability and ease of use associated with closed additive manufacturing ecosystems. Its physics-based thermal simulation generates part-specific print settings, and its hardware includes automation and in-process monitoring intended to produce quality-verified parts.

Technology

AON3D's platform centers on physics-based thermal simulation software that creates dynamic, part-specific print settings, combined with the Hylo printer's built-in hardware automation and in-process monitoring. Basis software handles workflow, part qualification, and job management. Hardware is composite-ready and supports high temperature polymers such as PEEK and ULTEM.

Go-to-market

The company markets directly through its website with quote and demo requests, and publishes customer application examples in aerospace, space, and autonomous vehicle sectors.

Engineering and manufacturing organizations producing end-use and prototype parts, including aerospace and defence, space systems, and autonomous vehicle companies. Named users include Locomation (end-use sensor housings for autonomous trucks), Astrobotic (lunar lander components), and Opterus (high temperature composite molds for expandable space structures).
