Torture isn’t generally thought to be a good or useful thing. However, in the context of 3D printer calibration, “torture” is used to describe a maker’s best friend: torture calibration tests.
Torture test models are designed to specifically test certain abilities of your 3D printer. For example, one model may test your printer’s ability to span bridges or print overhangs. Other torture tests might test dimensional accuracy or surface finish. Still, others may test slicer settings such as speed, temperature, or layer extrusion. And there are also tests specifically designed for resin printers.
Ready to challenge your printer? We’ve found the best calibration tests to assess your printer’s capabilities. Let’s do it!
Let’s start with the classic: 3DBenchy is the flagship of all 3D printer torture tests. This model tests everything from overhangs to extrusion.
If you want to put your printer to the test, Benchy will help you pinpoint the settings to tweak for perfect prints. And a few Benchys hanging around your printer is a sure sign of a seasoned maker!
This all-in-one 3D printer test is exactly what it says it is! Overhangs, bridges, stringing, extrusion, temperature, belt tension – this model tests them all. If you want to test your printer on multiple layers (pun intended), be sure to try this torture test!
After printing, if there are some parts that need attention, you can find a fix by reading our comprehensive troubleshooting guide.
This Halloween-themed stress test is intended to verify the bridging capabilities of your machine. If all goes well, you shouldn’t see any stringing or loose strands of filament. The model consists of a thin web supported over a base and a cute spider perched on the web.
The web bridging is considerably wide and consists mainly of single lines of 3D printed filament, so it’s a challenging and fun print to try. Of course, no supports should be used during the print, and a 0.2-mm layer height or smaller is recommended. The creator recommends keeping an eye on things while printing, as there’s plenty that can go wrong!
This eight-sided calibration test has an empty center and devotes each side to a few specific 3D printing challenges. A total of 21 different elements are tested, including negative space (indentations), dimensional accuracy, overhangs, warping, and spikes (sharp points).
Dimensional accuracy looks like it was a primary concern for the designer because they listed how long or large each feature should be in the project’s description.
Next, this print-in-place toaster with two hinged doors and a lever will put your printer to the test! 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 up, just like on a real toaster. However, if your printer isn’t up to the task, your toast won’t be able to move!
The creator recommends printing with 20% infill and a 0.2-mm layer height as a starting point. No brim or supports are required.
This calibration cube is a simple, fast, and easy model to put your printer to the test. Its primary goal is to help you dial in your printer’s dimensional accuracy by tweaking its axes’ steps per mm. But you can also use it to test temperature, extrusion, and vibration.
Cali Cat (shortened from the Calibration Cat) is a simple and adorable model that tests your printer’s dimensional accuracy, overhangs, detail, bridging, extrusion, and vibration in under an hour! Designed for initial calibration, this cat will help you achieve purr-fect prints in no time at all.
Pro Tip: If you print one cat twice as big as another, the small cat will fit squarely on top of the big one.
This poseable, print-in-place robot features 17 functional joints with different orientations, couplings, and tolerances. Ranging from 0.2 to 0.5 mm, the tolerances let you test the minimum clearances your printer can produce while still achieving movement in all of the joints.
The designer explains that this model is intended to be used as a tool to find the best settings for your printer. They found success with the following settings: 0.4-mm nozzle, 0.2-mm layer height, PLA, 3 walls, 4 floors/roof, and 10% infill. You’ll only need 20 g of filament to print one of these cute bots!
Phil A. Ment is MatterHackers’ adorable mascot, designed to help makers calibrate their printers to a ‘T’. According to the company’s description, “Phil has several features specifically to put your printer through its paces.” The torturous targets include some small embossed and inset details and the smooth dome of Phil’s helmet. Other tricky tests include overhangs, bridging, cylinders, fillets, and chamfers.
The smallest and largest recorded prints are 5- and 1,397-mm tall, so scaling this test print should be no trouble. You can even choose from several versions of Phil, including models optimized for resin and even a Santa Phil!
As the name implies, this model is a smart, compact temperature calibration tower. It tests overhangs, bridges, stringing, and even your printer’s ability to print curvy shapes. Of course, it’s also a great way to quickly calibrate your printer’s temperature for a particular material.
This hollow calibration cube is a test print in the shape of a wireframe cube with a solid base. In other words, as seen in the image above, this test only prints the edges of a cube, leaving gaps for the faces.
Overall, this test is a quick and effective way to test retraction, oozing, bridging, dimensional accuracy, and layer shifting.
This open-source model, coming from Kickstarter and Autodesk, is meant to provide makers with a standard test to assess 3D printer performance. Many makers like to showcase their machines by having it 3D print a tricky model.
But when one person prints a 3D Benchy and another prints a vase, it’s hard to know how the two 3D printers compare. This single STL file employs a variety of features, like bridges, overhangs, and fine detailing, in order to test for accuracy, resolution, and alignment.
This simple and fast-to-print model is aimed at tweaking your printer’s Z hop, which is basically a slicer setting that prevents your model from being knocked over by the printhead mid-print. In addition, fine-tuning the Z hop setting can help you achieve smoother prints, as it gives the nozzle some clearance.
The designer notes that while this model looks fairly simple, it’s still difficult to print. You can print it with or without a brim to test bed adhesion.
The PolyPearl tower is a great print to test bridging, curves, overhangs, stringing, and much more. Described as a torture tower with a twist (literally!), this model is sure to help you quickly calibrate the ideal settings for your printer or filament.
This next calibration print consists of many 5-mm cubes in a stair-step pattern up the side of a quarter-pyramid. However, if the design only had 5-mm cubes, it wouldn’t be testing much; the model also contains gaps to serve as bridging tests.
According to the designer, this calibration model allows you to check your printer’s dimensional accuracy, bringing capabilities, cooling settings, and E-steps.
Tolerances are a critical aspect of functional 3D prints. Adjusting them can be tricky and time-consuming. According to comments from users, this clearance tolerance test is small and fast to print. That way, it will save you time.
The design has six different clearance tolerance gaps, starting with 0.1 mm and increasing to 0.35 mm. It consists of a main structure with detached parts around it. The goal is to verify if the detached parts move after the print is finished. If they are stuck in place, you can work on your printer, the printing parameters, or your materials to improve your tolerances to a… tolerable level.
You can check the range of parameters other makers have used and compare them to your values in the comments from the community.
Bed leveling is often the trickiest part of 3D printer calibration. This model is here to help! It helps you see how to improve your first layer to produce the best prints.
This test highlights the effects of staircasing on prints based on the slope’s angle. Staircasing is the appearance of tiny steps instead of smooth curves, an almost unavoidable result of producing a part in layers.
This design includes nine different angle arrangements (each of two angles that add to 90°) starting from 5° and 85°, letting you see which angle works best to minimize the stair-casing effect on prints with a slope.
Once you find the right angle, you can properly orient models that contain a curve so that the curve is at the determined angle and the slope will look more uniform and natural. Alternatively, you can print a few of these calibration models at different layer heights and use the one that works best.
The tech magazine Make: has made its own assortment of test prints for 3D printers. In total, there are seven different calibration tests covering many printing challenges, including bridging, X-, Y-, and Z-axis resonance, fine detail, dimensional accuracy, overhang angles, and more.
This adorable model isn’t intended to test precision and tolerances. The goal here is to verify other parameters focused on less technical prints that just have to look pretty. To accomplish that, the Cali-Dragon allows you to test surface smoothness (layer consistency), stringing, small perimeters, overhangs, ghosting, and details. This design looks so nice that it also serves well as a material test to verify the color and quality of a new filament spool.
The creator says that it can be printed with no infill at all, and other printing parameters like layer height and wall count will be defined as the way you wish to test the parameters of your printer. A suggestion is to start with a 0.2-mm layer height and three walls, then tweak according to your needs.
