【3D Printing】9 Free 3D Printer Torture Test Models

 
All-in-one
This all-in-one 3D printer test does exactly what its name suggests!
Overhangs, bridges, stringing, extrusion, temperature, belt tension — this model tests all of them.
If you want to test your printer on multiple items, be sure to try this torture test!
Who designed it: majda107
How popular is it: Over 220 Thingiverse users have posted makes of this model, including various interesting failures and stunning successes. Hopefully, after tuning your machine, yours will be one of the successful ones.

Spiderweb
This Halloween-themed stress test is designed to verify your machine's bridging capabilities.
If all goes well, you should see no stringing or loose filaments.
The model consists of a thin web supported by a base and a cute spider perched on the web.
The web bridges are quite wide and consist primarily of single rows of 3D printed filament, making this a challenging and fun print to attempt.
Of course, no supports should be used during printing.
Who designed it: E3D_
How popular is it: With over 15,000 downloads and nearly 800 shared makes, this model is definitely printable.

Torture Toaster
Next, this 3D printed toaster with two hinged doors and a lever will put your printer to the test!
It aims to verify tolerances, overhangs, and bed adhesion. If all goes well, you should be able to push the lever to pop out the toast, just like on a real toaster.
However, if your printer isn't up to the task, your toast won't move! The creator suggests printing with 20% infill and a 0.2mm layer height as a starting point. No brims or supports are needed.
Who designed it: Clockspring
How popular is it: This design has approximately 43,000 downloads and over 350 posted makes online.

Cali Cat
Cali Cat is a simple and cute model that can test your printer's dimensional accuracy, overhangs, detail, bridging, extrusion, and vibration in under an hour!
Designed for initial calibration, this cat model will help you achieve perfect prints in no time.
Plus, if you print one cat twice the size of another, the smaller cat will fit perfectly on top of the larger one.
Who designed it: Dezign
How popular is it: Over 600 Thingiverse users have posted makes of this model, and there are over 110 modified versions! Prints have been made on many different machines using a variety of materials.

Calibration Robot
This posable, print-in-place robot features 17 functional joints with varying orientations, couplings, and tolerances.
The tolerances range from 0.2 to 0.5 mm, allowing you to test the smallest gap your printer can produce while still achieving movement in all joints.
The designer explains that this model is intended to be a tool for finding the optimal settings for your printer.
They found success with the following settings: 0.4 mm nozzle, 0.2 mm layer height, PLA, 3 perimeters, 4 top/bottom layers, and 10% infill.
You only need 20 grams of filament to print a cute robot!
Who designed it: Kazi Toad
How popular is it: This fun test model has over 4,000 downloads and 63 shared makes online.

Phil A. Ment
Phil A. Ment is MatterHackers' lovable mascot, designed to help makers calibrate.
The challenging features include some small embossed and inlaid details and the smooth dome of Phil's helmet.
Other tricky tests include overhangs, bridging, cylinders, fillets, and chamfers.
The minimum and maximum recorded print heights are 5 mm and 1,397 mm respectively, so scaling this test print should not be an issue.
You can even choose from multiple versions of Phil, including models optimized for resin and even a Christmas Phil!
Who designed it: MatterHackers
How popular is it: Over 200 variations have been posted on Thingiverse, with many sharing their army of Phil A. Ments!

5mm Steps
This next calibration print consists of many 5mm cubes arranged in a stepped pattern on the side of a quarter pyramid.
However, if the design only had 5mm cubes, it wouldn't test much; this model also includes gaps as a bridging test.
According to the designer, this calibration model allows you to check your printer's dimensional accuracy and cooling settings.
Who designed it: MCroucher
How popular is it: This 5mm cube test print has nearly 230 recorded makes on Thingiverse, with 9 modified versions. Most of the shared images are successful prints, so achieving a nearly perfect print of this model should be possible.

Slope Angle
This test highlights the effect of stair-stepping on prints based on slope angle. Stair-stepping is the appearance of tiny steps instead of a smooth curve, an almost inevitable result of FDM prints.
This design includes nine different angular arrangements from 5° to 85° (each angle adds up to 90°), allowing you to understand which angle works best to minimize the stair-stepping effect on prints with slopes.
Once you find the correct angle, you can orient models containing curves correctly, placing the curves at the determined angle, and the slopes will appear more uniform and natural.
Alternatively, you can print some calibration models at different layer heights and use the one that yields the best results.
Who designed it: Devstroyer
How popular is it: This slope test print has over 24,100 views and over 2,100 downloads. Although there are no community prints, the designer has posted many images of beautifully printed items, so printing this calibration model should be easy.
