However, in the context of 3D printer calibration, torture is used to describe the manufacturer's best friend: the torture of calibration testing.
The torture test model is designed to specifically test certain functions of a 3D printer.
For example, one model can test a printer's ability to cross a bridge or print overhangs.
Other torture tests may test dimensional accuracy or surface finish.
However, others may test slicer settings such as speed, temperature, or layer extrusion.
Ready to challenge your printer? We've found the best calibration tests to evaluate printer capabilities. Let's get started!
3D Benchy
Let's start with the classic, the 3DBenchy boat, the flagship of all 3D printer torture tests. This model tests everything from overhangs to extrusions.
If you want to test your printer , Benchy will help you determine the settings to achieve perfect printing.
Having some Benchys around the printer is undoubtedly a sign of an experienced manufacturer!
Who designed it: Thingiverse
Its popularity is remarkable: over 4,000 different variations of this model have been shared online. Benchy has used hundreds of machines and materials to print in every imaginable color.

All-in-one
This all-in-one 3D printer is truly living up to its name!
Suspension, bridge, tension, compression, temperature, belt tension—this model tests all of these.
If you want to test your printer on multiple projects, be sure to try this torture test!
Who designed it: majda107
Its popularity is remarkable: Over 220 Thingiverse users have posted examples of how to build this model, including various amusing failures and astonishing successes. Hopefully, after tweaking your machine, it will become one of the successful ones.

Spider web
This Halloween-themed stress test is designed to verify your machine's bridging capabilities.
If everything goes well, you should not see any stringy or loose strands.
The model consists of a thin web supported on a base and cute spiders perched on the web.
The network bridging is quite wide, consisting mainly of single-line 3D printing lines, making it a challenging and interesting printing experiment.
Of course, supports should not be used during the printing process.
Who designed it: E3D_
It's incredibly popular: the model has over 15,000 downloads and nearly 800 shared creations, so it's definitely printable.

Torture of vomiting drivers
Next, this 3D printing toaster with two hinged doors and a control lever will test your printer!
It's designed to verify tolerances, overhangs, and bed adhesion. If all goes well, you should be able to push the lever to pop the toast out, just like on a real toaster.
However, if your printer isn't up to the task, your toast won't move! The creators recommend starting with 20% fill and a 0.2mm layer height. No edges or supports are needed.
Who designed it: Clockspring
How popular it is: the design has been downloaded approximately 43,000 times and published in over 350 places online.

Cali Cat
Cali Cat is a simple and adorable model that can test a printer's dimensional accuracy, overhang, detail, bridging, extrusion, and vibration in just one hour!
This cat model is designed for initial calibration and will help you achieve perfect print results immediately.
Additionally, if you print one cat that is twice the size of another cat, the kitten will fit perfectly on top of the larger cat.
Who designed it: Dezign
It's incredibly popular: Over 600 Thingiverse users have posted information about the model's creation, and there are over 110 modified versions! It was printed using a variety of materials on many different machines.

Calibration robot
This poseable in-situ printing robot has 17 functional joints with different orientations, couplings, and tolerances.
With tolerances ranging from 0.2 to 0.5 mm, it allows you to test the minimum clearance a printer can produce while still allowing all joint movement.
The designer explained that the model is designed to be used as a tool to find the optimal settings for a printer.
They found the following setup to be successful: 0.4 mm nozzle, 0.2 mm floor height, PLA, 3 walls, 4 floors/roof, and 10% fill.
You only need 20 grams of filament to print an adorable robot!
Who designed it: Kazi Toad
How popular it is: This fun test model has been downloaded more than 4,000 times and shared 63 times online.

Phil A. Ment
Phil A. Ment is MatterHackers' adorable mascot, designed to help manufacturers with calibration.
The most striking features include some small relief and inlay details, as well as the smooth dome of Phil's helmet.
Other challenging tests include overhangs, bridging, cylinders, fillets, and chamfers.
The minimum and maximum print heights recorded were 5 mm and 1,397 mm, respectively, so scaling this test print should not be a problem.
You can even choose from multiple versions of Phil, including models optimized for resin, and even Christmas Phil!
Who designed it: MatterHackers
How popular is it: Over 200 varieties have been posted on Thingiverse, and many people have shared their Phil A. Ment armies!

Five millimeter steps
The next calibration print consists of many 5 mm cubes arranged in a stepped pattern on the side of the quarter pyramid.
However, if the design is only a 5 mm cube, not much testing will be done; the model also includes blank spaces for bridging tests.
According to the designer, this calibration model allows you to check the printer's dimensional accuracy and cooling settings.
Who designed it: MCroucher
Its popularity is remarkable: this 5mm cube test print has nearly 230 records on Thingiverse, including 9 revised versions. Most of the images shared so far are successful prints, so achieving a near-perfect print of this model should be possible.

tilt angle
This test highlights the impact of stairs on slope-based printing. Stairs appear as tiny steps rather than smooth curves, a nearly unavoidable consequence of FDM prints.
This design includes nine different angle arrangements ranging from 5° to 85° (each angle adds up to 90°), allowing you to understand which angle is best suited to minimize the staircase effect on prints with ramps.
Once you find the right angle, you can properly orient the model containing the curve, so that the curve is at a certain angle and the slope looks more even and natural.
Alternatively, you can print several calibration models at different layer heights and use the one that works best.
Who designed it: Devstroyer
Its popularity is remarkable: this ramp test printout has been viewed over 24,100 times and downloaded over 2,100 times. While there are no community printouts, the designer has posted images of many beautiful printouts, so printing this calibration model should be easy.
