Adjusting print settings
This article explains the Print Settings panel for the different types of printers that GrabCAD Print supports.

Print settings for FDM printers
These properties can be changed for individual parts on the tray. Select models with left-click, either in the 3D viewer or the models list in the Project Panel. Add to your selection with ctrl+click.
Support style and Infill style
To learn about the different styles, read more here.
Thicken Thin Walls
When the model is sliced, some areas of the slice may be narrower than a single toolpath width (twice the slice height). With this setting enabled, toolpaths will be generated anyway. If this setting is disabled, toolpaths will not be generated where they do not fit. If the setting is not available, it is on by default.
These properties must be the same for all models on a tray.
The available options for slice height depend on the selected printer. To learn more about slice heights, read more here.
Model and support material
Each time you open a new project or create a new tray, these will be set to default values, which are the most commonly used materials. If your printer is loaded with different materials, select them here to get an accurate estimation. Check which materials are loaded in the printer by clicking on your printer in the Printer Panel.
Part build style (F123 Series only)
Draft Mode — Uses model material for the generated supports, except for a thin layer where the supports meet the model. This reduces the number of material swaps per layer, which reduces build time. If you have selected PLA as your material, this option is not available, because with PLA, all supports use model material.
Brick Mode — Helpful when printing large, dense, solid-fill parts to reduce part curl. This is only when using a slice height of 0.005” with ABS, ASA or PC-ABS.
Purge part type (F123 Series onle)
F123 Series printers use a purge part on the tray instead of a purge bucket behind the tray. This reduces head movement per layer, reducing print time. Purging is needed when the printer swaps from printing model to support material in each layer. Often, the upper layers of a print will not use any support material, so purging is not required. This setting adjusts the height of the purge part.
Last Swap: the purge part will only be as tall as the last layer of support material
Full Height: the purge part will go all the way to the last layer of model material.
In model view, the purge part on the tray will always display as "Full Height" regardless of your setting, but if you go to Slice Preview you can see the actual height.
Note: If you have selected PLA as your material, there is no purge part, since support material is not used.
Print settings for J750
For the J750, material selection is in a separate pop-up:
If you are preparing a print with materials other than what's currently loaded, you can use this panel to customize your tray materials. If you have made changes in this list and want to revert back to what is loaded, click "Get printer's loaded materials."
Because CMYK printing does not cover the full spectrum of colors available in RGB, GrabCAD Print performs some approximation to get the color as close as possible. The Color profiles and Texture profiles options change fine details about this approximation. This is similar to adjusting display modes on your monitor or TV.
- Natural Texture (default) — Realistic rendering many of VRML models (UV-mapped and non-shell based). This is the profile of choice for thin models.
- Vivid Texture — Richer and more vivid rendering of dark colors. Red, green, and blue colors are similar in hue to those seen on a monitor.
- Crimson Shells — Red colors are more similar to those seen on a monitor.
- Natural Shells (default) — Realistic rendering of thick shell-based models. Out-of-gamut colors are mapped to the closest printable color.
Glossy produces a shiny finish on the top surfaces of the model, and Matte produces a uniform finish on all surfaces.
You can add a coating to your model and choose it's thickness.
For models without a texture, you can choose a color using a variety of methods:
— Select one of the six tray materials
— Pick a color in the color picker
— Pick from a color palette generated from a subset of the available materials. Use the "Filter by" dropdown to select a palette
— Enter the color manually using the hex code, RGBA, or HSLA values
If Tango+ is a loaded material, you can use the Shore-A slider in addition to the color picker to determine the amount of Tango material used in the mix. Higher Shore-A level means more Tango is used, resulting in a softer material.
This determines how much model material is added in the support. When Tango+ is loaded, "Heavy" is the recommended setting.
You can print a hollow model and determine the thickness. If you are printing a VRML file with texture, be sure to select at least 3mm thickness.
