This section describes troubleshooting issues with printed-part quality. The chart below discusses specific troubleshooting issues; however, there are several best practices that can help fix a lot of print-quality issues:
Use the appropriate print mode for your parts
- Standard for small parts or large, thick parts
- Delicate for lacy, thin parts or parts with small and fragile features
- Avoid print jobs where different parts in the bin are made from both types of print modes.
- Clean the Roller and Blade before each print job. Inspect the blade for any signs of wear or inadequate function; if worn or damaged, replace.
- Be sure the roller is fully seated in the keyed feature on the roller assembly.
- Clean the Printhead Station before each print job. Inspect the Wiper for signs of binder buildup, warping, or wear. Ensure that it is also level.
- Ensure the Cap is not damaged, and that it is fully seated on the printhead station base. The barbs on the underside of the printhead station should be fully underneath.
- Ensure the printhead station clicks into place upon reinstallation.
- Run Clean Printhead from the touch screen, especially if the printer has been sitting idle recently.
- Use only Brill Culinary 3D Powder within its expiration date; do not add any of your own ingredients.
- Adhere to powder storage and usage recommendations.
- Only use Brill Culinary 3D Binder within its expiration date; do not add any of your own ingredients. Do not reuse binder from the waste bottle.
- Always keep binder tank lids closed, except when loading binder.
- Adhere to ambient temperature and humidity ranges listed in the Facility Requirements Guide.

Part crumbling - sections are crumbly or separate completely.
Crumbling parts are those that “turn to dust” as they are being removed from the build bin. This is usually due to very poor printhead jetting and is most likely to occur on jobs having lots of thick parts. If part is crumbling:
Other information about poor jetting:
If the printer has been mistakenly powered off for too long, has recently completed an in-place cleaning, or has generally been sitting for an extended period of time, some recovery steps and time will be needed to restore jetting:
Severely warped/distorted parts
Rough surface finish, voids, and jagged edges
Part of build bin caves in.
Roll over to zoom.
This is usually caused by "short spreading," which occurs when not enough powder spreads to an individual layer in the Build Bin. This can happen with a full-height build of either one large part, or densely packed smaller parts. A build like this will use large amounts of binder, which can absorb enough powder that the volume of the ingredients in the build bin goes down. This can in turn cause a layer of fed powder not to spread evenly, causing the issues in the description at the left. These effects will only be seen in the top layers of the build. To troubleshoot this:
Orient your parts in 3D Sprint so that the longest part is perpendicular to the direction of powder spreading. Consider the following example:
If filling the build plate, ensure that your parts are spread at least 5 mm apart.
Parts show wrinkling on one side
This results from oversaturating the part and shows up on downward-facing surfaces, especially curved surfaces.
|PPQ5||Parts are distorted in the Z direction
This results from oversaturating the part and can result in some elongation in the Z direction.
Parts have mottled color appearance with rough surface finish. Some areas are much darker with higher binder concentration.
This is usually caused when the Saturation setting in 3D Sprint is set too high. To troubleshoot:
Parts having banding or visible layers lines through one direction of the build.
|This is usually in the Z axis. This is within the spectrum of expectation to happen occasionally.|
Part is cracked, with a defined split occurring evenly at a single layer
This is usually caused by pausing a print for too long. Pausing a print is not recommended.
Parts feature unintended coloring. Typically observed on white parts
Bad color mixing
This can be caused by different-colored parts being too close to each other in the Build Bin, or by the Printhead Station transferring binder to the Printhead.
If colors within the build are mixing together:
Parts have been dragged within the build area, or display evidence of a sheared edge/break.
This can be caused by a dirty Roller/Roller Blade, or by the powder being unsifted or clumpy.
