Stratasys FDM 3D Printing

FDM (Melt Deposition Molding) 3D printer, as a widely used 3D printing technology, is favored by users for its low cost and simple operation. However, printing efficiency often becomes a key factor restricting its application range. This article will explore several effective ways to improve the printing efficiency of FDM 3D printer.

First, reducing the printing accuracy is a common way to increase the printing speed. By adjusting the Settings of the slicing software, selecting low-quality print options, or increasing the print height, you can significantly reduce the print time. For example, adjusting the default print height from 0.2mm to 0.4mm can double the speed. However, this method sacrifices the surface accuracy of the printed work, so it is suitable for models that do not require high accuracy.

Secondly, reducing the filling rate is also an effective means to speed up. Usually, the filling rate of 3D printed models is set at around 20%. Reducing the fill rate not only saves consumables, but also reduces printing time. However, it should be noted that the filling rate should not be too low, so as not to affect the strength and stability of the model. Especially when printing models with top surfaces, a lower fill rate can result in uneven top surfaces. Therefore, it is very important to adjust the filling rate reasonably according to the characteristics of the model.

Segmentation model to reduce support is also an effective way to improve printing efficiency. By splitting the model, the number of supporting structures can be reduced, thus reducing printing time. Although the segmentation model adds some print planes, the overall print time can still be optimized due to the reduction of the support structure. In addition, a reasonable setting of the top wall thickness can ensure the strength of the model while avoiding printing defects caused by low filling rate.

Finally, hardware upgrading is also one of the important ways to improve printing efficiency. For example, the laser-assisted desktop FDM 3D printer developed by the Massachusetts Institute of Technology, through the laser head high-speed heating and melting of the basic material, with a special threaded mechanical principle of the nozzle, so that the printing speed than the traditional desktop FDM 3D printer ten times faster. This technology not only improves the printing efficiency, but also expands the application prospect of FDM 3D printers in the production process.

In summary, the printing efficiency of FDM 3D printers can be effectively improved by reducing the printing accuracy, reducing the filling rate, reducing the support of the segmentation model and hardware upgrading. Users can choose the right method according to their specific needs to achieve a significant increase in printing efficiency.
