What is the printing effect of different nozzle sizes of pellet 3d printer?

2022/09/27

We all know that the nozzle is one of the most important parts in FDM/FGF (Fused Deposition Modeling) 3D printing equipment. It largely determines the quality of the 3D printed product. In order to meet different printing speed and printing accuracy requirements, the diameter of the nozzle is from 0.4-4.0mm. Generally speaking, if you pursue speed, you must give up accuracy to choose a large nozzle, and if you pursue accuracy, you must give up speed and choose a small nozzle. Now what we see is the G5 PRO, the pellet material 3D printer of Piocreat. We used 0.5, 0.8 and 2.0mm nozzles to print the same vase model, and the printing effect and speed were completely different.


In this printing test, we used PETG+10% glass fiber. The temperature of the printing nozzle is set at 230 ℃, and the temperature of the printing platform is 80 ℃. The length of printing time varies with different nozzles. The larger the nozzle, the shorter the printing time. See the following test data for details:

0.5mm layer height 0.2 printing time 9.5 hours printing speed 60mm/s
0.8mm layer height 0.3 Printing time 7.5 hours Printing speed 60mm/s
2.0mm storey height 1.2 Printing time 5 hours Printing speed 30mm/s

 
These are the three vases that have just been printed by the pellet material 3d printer G5 PRO. Let's zoom in to see how different their layers are. After comparison, we can see that the vases printed by the 2.0mm nozzle can clearly see the layers of textures, the 0.8mm nozzle is slightly better, and the vases printed by the 0.5mm nozzle can hardly see the layers. Therefore, if your model does not pursue precision, you can use a large nozzle to retain the original layers to make your model more beautiful with lines, and the printing speed is fast, such as applications in the sculpture and furniture industries. If you need higher precision, a smaller nozzle is a good choice, because the diversity of pellet 3D printer materials can meet the performance requirements of different industry models, such as figures, molds, fixtures and other applications.
