Fused Depositation Modeling (FDM) can achieve higher intensity molding parts, which is mainly due to the following key factors.
First of all, the selection and optimization of materials is an important part. FDM materials such as PLA and ABS have their unique performance. Taking PLA as an example, it is a biodegradable material with a high crystallinity, making the molding parts have a certain rigidity and strength. ABS materials have good impact resistance and toughness. When producing these FDM consumables, manufacturers can significantly improve the strength of the material by adding enhanced fiber, such as carbon fiber, glass fiber, etc. These fibers can be evenly distributed in the plastic matrix. When the material is squeezed out and cooled for molding, the fiber is like a skeleton, which bears and transmits stress, thereby enhancing the strength of the entire molding part.
Secondly, the FDM printing parameters have a key impact on the strength of the molding parts. The layer thickness setting is one of them. The smaller layer thickness can make the binding between each layer more closely and reduce the weaknesses between the layers. For example, when the thickness of the layer is reduced from 0.3mm to 0.2mm, the bonding effect between the layers is better, and the formation parts are not easy to crack from the layer when they are tolerate or stress. In addition, the precise control of printing temperature is also important. The appropriate temperature can ensure that the material is fully melted, so that it can be better integrated together during the deposition, improve the cohesion inside the material, and then enhance the overall strength of the molding parts.
Furthermore, the fill mode and density of FDM printing also play a role in improving intensity. The appropriate filling pattern, such as honeycomb, triangle, etc., can more effectively disperse stress. Moreover, increasing filling density means that there are more materials inside the molding part to support the structure. When a higher -intensity molding part is required, the filling density can be increased from a lower level (such as 20%) to a higher level (such as 60%), so that the molding parts can better resist deformation when external forces are affected.
Finally, the post -processing process also helps improve the strength of the molding parts. For example, the printing of the printed parts can eliminate internal stress, make the molecular structure of the material more stable, and further enhance the strength and stability of the molding parts.
