If you’re just starting in the world of 3D printing, you may have heard about a small, boat-shaped model called a “benchy.” This little boat has become a staple in the 3D printing community as a universal test model, or “benchmark,” that can help new and experienced users alike fine-tune their printers. But what makes this tiny boat so important, and why should you make one? Let’s find out, shall we?
What Is a Benchy?
A benchy, short for “benchmark,” is cute – but it’s actually designed to test your 3D printer’s capabilities on multiple levels. The shape, angles, and details of this little boat make it the perfect model to uncover common printing issues and ensure that your printer is calibrated correctly.
Why Print a Benchy?
The benchy is a meticulously designed tool to stress-test your printer and highlight any issues with alignment, accuracy, and quality. With its intricate details and specific measurements, printing one of these is a no-brainer as it provides a reliable way to spot and troubleshoot any imperfections in your prints. Here’s what it can reveal:
- 1. Layer Alignment and Surface Quality: The smooth sides and rounded edges of the benchy are great indicators of how well your printer handles layer alignment. If there are visible lines or rough textures, this could suggest issues with your print settings or the need for better calibration.
- 2. Overhangs and Bridging: One of the standout features of a benchy is its overhangs – like the cabin roof, windows, and doorways. These features test your printer’s ability to handle unsupported sections, which can sag if the cooling settings aren’t dialled in properly. The bridge over the cabin area is particularly helpful for testing this aspect.
- 3. Small Vertical Features: The benchy’s smokestack (chimney) is a tall, narrow element that’s ideal for testing how your printer handles small, vertical details without wobbling or tilting. Any issues here may indicate that adjustments to your print speed or layer height are needed.
- 4. Dimensional Accuracy: With its precisely designed portholes and doors, the benchy allows you to test how well your printer keeps to scale. If these details are off-size or slightly deformed, it could mean your printer’s steps-per-millimetre settings require calibration for better dimensional accuracy.
Printing Your First Benchy: A Step-by-Step Guide
Getting started with a benchy is simple, and it’s an ideal way to learn the basics of your 3D printer’s performance. Here’s a quick guide:
- Choose Your Slicer Settings
Start with basic settings for your filament type, typically PLA for beginners, with a layer height around 0.2mm. You can always experiment with different settings as you become more comfortable with your printer. - Watch the Print Closely
Watching your benchy as it prints helps you catch issues like filament clogging or bed adhesion problems early. This first print can reveal potential problem areas that might not be visible in less detailed models. - Analyse the Results
Once your benchy is finished, examine each feature closely. If you notice stringing (fine strands between parts), layer shifts, or rough surfaces, it’s an opportunity to learn and make adjustments to improve your next print.

Common Troubleshooting Tips
- Stringing
If you see thin, wispy strands between features, try adjusting your retraction settings to reduce filament flow during non-printing moves. - Layer Shifts
Misaligned layers could indicate that your belts need tightening, or that your print speed may be too high. Tightening the belts or lowering the speed should help. - Warping
If the base isn’t perfectly flat, consider increasing your bed adhesion by adding a brim or adjusting the bed levelling settings.
Embracing the Benchy as a 3D Printer’s Benchmark
Printing a benchy is your right of passage into the 3D printing community. It’s a tradition that connects you to 3D printing peeps all over the world. It’s a symbol of the learning process, a marker of progress, and a fun way to get hands-on experience with your printer. Each benchy you print brings you closer to mastering the art of 3D printing, one layer at a time.
Happy printing, and welcome to the 3D printing journey fam!
