FlashPrint Slicer Options

FlashPrint Slicing Overciew

As you become more familiar with FlashPrint you’ll likely want to begin experimenting with the advanced slicing options. FlashPrint has several settings that you can tweak, and this article will provide a brief overview of some of the more common ones.


Exploring the Slicer Settings

The slicer settings become visible once you click the Print button. When you click Print you’re actually choosing how your model will be sliced. During this time you’re able to use the default slicer profile or change some of the values used during slicing the model.

Note that if you slice a model and export the .gx file and then change some of the slicer settings you’ll need to export the .gx file again.

Before we jump into how to access the more advanced options, let’s look at some of the values that are displayed in the basic slicer window.

Enabling Support

One of the most commonly changed setting is enabling or disabling support material. The print options allow you to either enable or disable the generation of support material. If you select Enable FlashPrint will include support in your print based on the support settings you’ve selected.

Support options is accessible in main FlashPrint interface by clicking the Support button:

Once you click this button you’ll then be able to access some new settings. If you prefer FlashPrint to automatically analyze and generate support material, click the Auto Supports button. If you’d like more control, click the Supports Options button:

Support Options

The main two options to consider are the Supports Type and Overhang Thresh.

Supports Type: This is where you can select the type of support structure. There are benefits and drawbacks to each type. Generally, you should try to use Treelike as often as possible. Here’s a brief overview of each type:

  • Treelike: Tree support uses minimal material and is less dense. This type of support is ideal when you don’t have large, flat overhang. Since tree support is less dense it’s easier to remove from your finished prints and also leaves less marks on the print after removal.
  • Linear: Linear support uses horizontal rails and is useful for large, flat overhang. Linear support uses more material and can be more difficult to remove from finished prints, especially if the support material is condensed.

Overhang Thresh: This is the threshold for generating support. Support will only be generated for overhang that is greater than the selected angle measurement. For most prints you should be fine with leaving it at the default setting.

Once you click OK your support settings will be saved. You still need to enable the support in the slice options when printing.

Print Resolution

Besides support, the print resolution is one of the most commonly adjusted settings. The default setting is Standard. Changing the print resolution setting will adjust the Layer Height and First Layer Height values.

Higher resolution prints have shorter layer heights, so when you use a higher resolution setting you’ll notice that the layer height decreases. Since the layer height decreases, the printer will need to print more layers to compensate. As you increase the print resolution, you’ll notice that your print time will also increase.

You can also customize the layer height and first layer height by either typing the value or using the arrows to adjust the values. This allows you to fine tune the exact settings that you want.

Note: If you want to change your print resolution after your model has been sliced you’ll need to change it and then re-slice the model.
