The following are the material experts' continuous experience and summary of 3D printing material development, and now they are shared for everyone to learn to adopt: There are several major quality issues with the quality of 3D printing consumables: First, the quality of raw materials; fluidity and viscosity are the two most important indicators; followed by whether the raw materials undergo some chemical changes during processing. Second, the accuracy of consumables. Mainly whether the consumables can be controlled within the tolerances. 3. Whether the consumables contain impurities. If the user is not professional, the identification of consumables is mainly observed from the following aspects. First, the naked eye 1.1 Please open the seal and carefully observe whether there is color difference in the consumables and whether the color is uniform; 1.2 Careful observation, whether there are tiny bubbles inside the inside; 1.3 If the consumables are transparent, please carefully observe whether the color of the material is uniform; under normal circumstances, the color is not uniform, indicating that the consumables have undergone some changes during production. 1.4 Whether the wire has a black or other color spot magazine. The naked eye observation is the most basic. After mastering the basics, Xiao Ge suggests that you can learn the advanced skills to understand the accuracy of the reason, even if the same 3D printer can greatly improve the accuracy problem. Second, accuracy 2.1 feel test accuracy. Pull out the 1-2 meter long consumables, gently clamp the consumables with your thumb and forefinger, and then slowly pull the consumables. If the consumables are uneven in thickness or the surface of the consumables is not smooth, the feel is easily perceived. 2.2 Instrument testing. Measured with a digital vernier caliper, multiple position measurements are within the control tolerances. 2.3 Measurement method. Measured within the length of 1-2 meters, the tolerance of the test wire diameter is uniform; at each test point, the range of 3-4 circumferences is measured by one rotation, mainly to measure whether the wire is "circular", that is, whether the wire diameter is controlled effectively. . Third, print and observe the quality of consumables 3.1 Observe the uniformity of the printed lines of the substrate. A typical printer has to make a substrate at the beginning of printing to observe the uniformity of the nozzle on the substrate. In general, it is more uniform and the consumable accuracy is controlled within the range. 3.2 Listen to the sound judgment. If the consumables are in normal operation, the gear feeding device will make a "beep" sound if the consumables are not uniform. 3.3 Print to judge the quality of consumables. Observe the uniformity of the internal structure of the consumables during printing. Whether there are problems such as bubbles or spots. 3.4 viscosity judgment. Consumables must have a viscosity during printing, otherwise the print will crack or detach. Considering the variety of consumables, the substrates of various printers are different, and the materials may be incompatible. To ensure smooth printing, it is best to apply some glue to the substrate. Otherwise, the printing is interrupted due to friction, collision, etc. of the printer and the model during the printing process.
