In the world of 3D printing, few models are as recognizable as the 3DBenchy. This small tugboat has become a standard test print for enthusiasts and professionals alike. But where did it come from, and why has it become so ubiquitous?

What Is the 3DBenchy?

The 3DBenchy, short for "3D benchmark," is a 3D model designed to test the capabilities of 3D printers. It includes various features that challenge different aspects of a printer's performance, such as overhangs, bridges, and fine details. The model is compact, allowing it to be printed in about one to two hours, making it a convenient tool for assessing print quality. I have seen it print it 16 to 17 minutes, but with reduced quality.

Origins and Creation

The 3DBenchy was created in April 2015 by Creative Tools, a Swedish 3D printing company. The model was designed by Daniel Norée, aiming to provide a comprehensive test object that could evaluate multiple aspects of 3D printer performance in a single print. The choice of a boat was intentional, as its shape incorporates various geometric features that are useful for testing.

The First Print

The original 3DBenchy model was uploaded to Thingiverse, a popular platform for sharing 3D-printable files. The first successful print was likely done using a consumer-grade FDM printer with PLA filament. This initial print served as a practical demonstration of the model's utility in identifying common printing issues, such as warping and layer misalignment.

Community Adoption

Following its release, the 3DBenchy quickly gained popularity within the 3D printing community. Users began sharing their prints online, comparing results, and discussing printer settings. The model became a common reference point for evaluating printer performance and troubleshooting issues.

Technical Features

The 3DBenchy includes several design elements that test various aspects of 3D printing:

Dimensional accuracy: Circular and rectangular holes to assess precision.

Overhangs and bridges: Features that challenge a printer's ability to print unsupported structures.

Surface finish: Curved surfaces and flat planes to evaluate layer consistency.

Fine details: Small text and intricate features to test resolution.

These elements make the 3DBenchy a comprehensive tool for printer calibration and benchmarking.

Variations and Remixes

Over time, the 3DBenchy has inspired numerous variations and remixes. Enthusiasts have created multi-color versions, scaled models, and even placed Benchies inside bottles. The model has been printed using various technologies, including SLA and SLS, and with different materials, showcasing its versatility.

Public Domain Status

In February 2025, the 3DBenchy was released into the public domain under the CC0 license. This move, following Creative Tools' acquisition by NTI, allows unrestricted use, sharing, and modification of the model, ensuring its continued relevance and accessibility within the 3D printing community.

Conclusion

The 3DBenchy has become more than just a test print; it's a symbol of the 3D printing community's collaborative spirit. Its widespread adoption and continued use underscore its effectiveness as a benchmarking tool. Whether you're a beginner calibrating your first printer or an expert testing new material, the 3DBenchy remains a valuable resource.
