Application of the week: Visual aid for manufacturing of Isofix strength test fixture

Welcome back to our application spotlight series, where we highlight real-world 3D printed parts that solve everyday industrial challenges - boosting speed, precision, and innovation across sectors.

This week, we’re spotlighting a simple yet highly effective tool: a 3D printed Isofix jig model, developed by Alberto Senosiáin Munárriz at Isringhausen to streamline the production of seat anchor testing equipment for vehicle safety compliance.

From regulation to reality - faster with 3D printing

In the world of automotive manufacturing, precision, and compliance go hand in hand. When it comes to installing Isofix anchorages - standardized connection points for child safety seats - manufacturers must ensure their systems meet UN Regulation No. 145, which outlines strength and safety tests.

The challenge? While the team had a hydraulic testing machine for seat belt anchors, they lacked the physical jig required to test Isofix anchorages in-house.

That’s when Isringhuser turned to additive manufacturing and the new UltiMaker S6.

Bridging the gap with a printed prototype

The team designed their own Isofix SFAD tool in line with the regulation. To support its fabrication, they printed a full-scale model of the tool on the UltiMaker S6. This prototype wasn't used for testing - but played a vital role in communicating the design to the welding team.

Thanks to the 3D printed version, welders could easily visualize the final shape, interpret complex welding plans faster, and manufacture the actual steel fixture with fewer errors and less guesswork.

Why it works: A simple print with big impact

Here’s how this 3D printed model added value:

Accelerated manufacturing By using a printed prototype as a visual guide, welders completed the job faster and with greater confidence - no time lost in confusing drawings.

Error reduction Having a physical reference minimized miscommunication and prevented costly mistakes during welding.

Cost-efficient compliance Rather than outsourcing or purchasing the jig upfront, the team used their internal resources to move faster and smarter.

Optimized with UltiMaker S6Printed in-house using the UltiMaker S6, the part was ready quickly and accurately - demonstrating how desktop 3D printing can complement even highly regulated workflows.

Smart solutions start with additive thinking

Whether it's for automotive safety, quality control, or equipment prototyping, additive manufacturing allows teams to fill critical process gaps without waiting on suppliers or third-party tooling.

With tools like the UltiMaker S6, even compliance-heavy industries can move faster - saving time, costs, and complexity along the way.
