If you’ve just received your 3D printer or are looking forward to 3D printing a complex design, starting with a test print is essential. Doing so will allow you to see what your printer, whether it’s one of the Best 3D Printers or not, is capable of and ensure that you won’t waste your time and materials on a project that won’t work.
Test prints let you see how well your 3D Printer or filament handles overhangs. They also allow you determine the best settings for temperature, speed, layer thickness, retraction, and other factors. You can use test prints even to find out how fast your printer can move. There are some models designed especially for testing your printer. Below we’ve chosen the six best test models for 3D printing.
1. 3D Benchy
3D Benchy can be used to test your 3D printer’s capabilities. Creative Tools originally created it. You can buy it from Official website of 3D BenchyClick on the website you want to access.
You must print the file as is, without any adjustments. This is a great print to tune and troubleshoot your machine because of its complexity. It is small and has different angles of overhangs to test the 3D printer’s ability to handle bridges.
The rectangular windows on the model and the sections of the design (as shown in the brochureIt is important to check the accuracy of your 3D printer by measuring the model after 3D-printing.
You can test the temperature control of your 3D Printer by looking at the overall print quality. For example, if you notice that the surface is smooth, but has rough edges or blots. Then, adjust the settings in your slicer.
Test your machine’s ability to handle intricate and fine designs by using the small holes and wheel-like shapes. The sections will be printed well if your 3D printer has been set up correctly. However, if you have issues, the holes may not be as large as expected.
Check your 3D Slicer’s settings to see if the holes are well or poorly visible. You can, for example, uncheck the Remove all Holes Cura allows you to leave the holes in place.
2. Calibration Cube
It is important to note that the word “you” means “you”. XYZ cube of calibration This tool helps to tune the accuracy of your 3D printing. It is a precise size, like 20mm each side. You can use a caliper to check the size of your print after printing. You will be able to tell how precise the stepper motors move. This is a crucial test print to be used if the size of the prints you are making is different from the size on the digital file.
You must align the model correctly in the slicer to ensure that the letters are parallel with the axis of measurement, as shown below.
In most cases the model will be imported with the right side up. After 3D-printing, measure and record the three sides.
Then you can compare the values for length, width and height in the slicer, to determine if they fall within the same range.
You will need to fine tune your machine if the sizes are very different. It can help you determine if your machine has been calibrated properly, as well as identify problems related to over- or under-extrusion.
3. All-in One 3D Printer Review
As the name implies, the all-in-one 3D printer tesTests how your 3D Printer handles different designs. Overhangs and supports are tested, as well as temperature and even bridges. The designer recommends using 100% infill without supports after downloading and slicing.
After 3D-printing, you should inspect every part and see how it is handled by your machine. You can identify any issues and decide what to do.
As an example, when I was designing my design, I found that some areas had stringing. To fix this, I adjusted the temperature and the retraction.
You can also change the temperature, speed and other settings in order to print it accurately.
4. Retraction Test
It is important to note that the word “you” means “you”. Test for retraction The model allows you to test the way your 3D printer pulls back the filament to the nozzle when it is moving from one end of the machine to the other. Stringing can occur if your retraction settings have not been set correctly. Stringing occurs when thin filament strands build up on your design as shown in the image below.
If you have stringing issues, you will need to adjust your slicer’s retraction speed. In most cases you will need to increase the speed a bit so that the filament retracts faster and doesn’t have time to ooze as the printhead moves.
You can also increase the distance if the strings still appear after increasing the retraction. In my case, i only increased the speed and it came out with no issues, although the tip of the Towers were slightly affected.
5. Smart Compact Temperature Calibration Tower
Smart compact temperature measurement tower This tool helps calibrate the 3D printer filament. You can determine the optimal temperature range and evaluate print quality for different temperatures. The temperature segments in the design increase gradually, and it’s easier to know how each section has been 3D printed.
You should not use supports. The designer recommends printing with an infill rate of 15%, a resolution 0.2mm and an infill rate of 15%. You can change your temperature settings after 3D-printing the design.
6. Flowrate Calibration print
Flowrate calibration print This is another test that will help calibrate your 3D printer’s flow rate. The flow rate is how fast the extruder is able to extrude the filament out of the nozzle. It is measured in millimeters/second. It impacts the speed and quality of printing. A lower flow rate slows down the printing speed, but produces finer prints. A higher rate, on the other hand, reduces the 3D printing time, though if it’s too high, it can result in issues like over-extrusion.
If you experience issues like oozing, over-extrusion, and poor-quality prints, it’s essential to 3D print this test model and use it to troubleshoot the problem.
Above are a small selection of test prints. You can use the design that is most appropriate for the problem you are trying to solve. You can start by testing the 3D Benchy and then move to the more complex 3D Cube. Finally, you could test your 3D Printer in its entirety. Most of these just take a few minutes or hours to print, so you can be sure they won’t waste your time or material.
