#3DBenchy is a 3D model specifically designed for testing and benchmarking 3D printers. It is a small recognizable object that you can download for free, make and share.

By 3D-printing this STL file you will be able to benchmark your 3D printer and materials and compare the result to other users' prints and machines.

The 3D model is designed to print at 1:1 scale without support materials. It is challenging for most 3D printers but the small volume (15.55 cm3) typically prints in well under two hours and does not require much material.
The different surfaces of the #3DBenchy model reveal typical issues regarding surface finish, model accuracy, warping, etc.

Step 1: Shape Features

  • The Hull - The hull is a large, smooth overhanging curved surface that is challenging to 3D-print and clearly reveals any surface deviations.
  • Symmetry - #3DBenchy is perfectly symmetrical which makes any skewness and warping easy to detect.
  • High-Resolution STL file - The STL file is triangulated at a very high resolution which yields smooth surfaces. The maximum deviation from the original CAD file is set to 0.001 mm.
  • Planar Horizontal Faces - The top surfaces of the deck, box and chimney are planar, horizontal and parallel to the bottom plane.
  • Tiny Surface Details - If you have a high-resolution 3D printer, this is where you can shine! The letters on the stern are less than 2 mm tall and the thickness of #3DBenchy’s nameplate is just 0.1 mm.
  • Cylindrical Shapes - The chimney is designed to define concentrical cylindrical shapes with inner and outer diameters. These clearly show deviations in roundness.
  • Overhang Surfaces - Overhang issues are the Achilles’ heel of 3D printing. #3DBenchy offers several challenging areas such as in the difficult-to-reach inside of the bridge.
  • Low-Slope-Surfaces - These clearly show the layered structure of 3D printing. If printed horizontally, #3DBenchy’s gunwale and roof of the bridge will reveal the layer-steps.
  • Large Horizontal Holes - The rear window offers a large circular horizontal hole and the boat’s wheel offers a round difficult-to-reach secluded feature.
  • Small Horizontal Holes - The hawsepipe represents a small short horizontal hole and has a very thin flange against the hull.
  • Slanted Small Holes - The fishing-rod-holder provides a very small slightly-slanted blind hole.
  • First-Layer-Details - The shallow letters at the bottom of the boat clearly reveal typical first-layer-squashing.

<p>For those who want to try #3DBenchy as a 3MF file in the slicing software, we have now created and uploaded the file 3DBenchy.3mf. It is a modern file format better suited for 3D printing. For more information visit http://www.3mf.io/</p><p>The original 3DBenchy.stl original file weighs 11,3 MB. The new 3DBenchy.3mf weighs just 3,1 MB but still contains the exact 3D surface information. Please note that not all 3D printing software packages today support the new .3mf file format.</p>
<p>I went to the 3dBenchy home page found a link for troubleshooting but the link doesn`t work,when My chimney is not 7 mm round or my storage compartment is not 12 mm square or i can read the name on the bottom of benchy but cannot read it on the stern where do i find where it explains to me what needs to be adjusted ? I downloaded the pdf file for 3dbenchy it has pictures for the &quot; Measure and Calibrate &quot; ok how and what needs to me calibrated ? What am I missing here aside from the knowledge to Calibrate ? </p>
<p>Our &quot;quick-fix&quot; for the issues you are experiencing, is to recommend you to check tension of the belts driving the X and Y axis of your 3D printer.</p><p>For a better analysis we would need to know much more about your machine, settings, material, 3D-printing environment, etc.</p>

Looks very nice! :) Thanks for sharing the images!
<p>We have now finalised the #3DBenchy STL files for dual- and multi-part color 3D printing! The files are now added to this instructable so that everyone can download them and give it a try. :)</p><p>Read more about dual-print at <a href="http://3dbenchy.com/?p=709" rel="nofollow">http://3dbenchy.com/?p=709</a></p>
<p>Great, I see it says my printer</p>
<p>This is a brilliantly designed test!</p>
Thanks! :) We are glad you enjoy it!
I am buying my first 3D printer in a few weeks but im going with a less expensive kit to get my experience building the printer and components. I understand the print qual will be low but I want to get a good grasp of how everything works hardware and software wise before going to a higher model. this will be the 1st print I do for sure to see where I stand.
We are glad to hear jtalor115 that your first print will be the #3DBenchy benchmark model! :)<br><br>Building your own 3D printer from a kit does not necessarily mean lower-quality results, many times it is the opposite because you can control and adjust every part of the machine.<br><br>Just make sure you make the mechanics as sturdy as possible, tighten the belts and lubricate all the linear bearings.<br><br>We suggest you start printing with PLA plastic filament because it is easier and yields better results. Just make sure to have a fan that effectively blows cool air onto the 3D-printed part while it prints.<br><br>Good luck and welcome to the fascinating 3D-printing world!
