Infill Added Over Walls When No Top Layer Enabled: A Critical Issue in 3D Printing

In the world of 3D printing, precision and accuracy are crucial for producing high-quality prints. However, there are instances where the printing process fails to meet these expectations, resulting in subpar prints. One such issue is the infill being added over walls when no top layer is enabled. This problem can lead to a range of issues, from aesthetic concerns to functional problems. In this article, we will delve into the details of this issue, explore its causes, and discuss potential solutions.

The issue at hand was reported by a user who encountered a problem with the OrcaSlicer software, version 2.2.0, on a macOS 15.3.1 system. The user was attempting to print a project using a Bambu X1C printer, but the infill was being added over the walls, resulting in an uneven surface. The project file and debug log were provided to help diagnose the issue.

The main particularity of the project is that it has no bottom and top layers. The external wall size is exaggerated (30 loops), and the infill is exposed. When the user attempted to slice the plate, the infill was added over the walls, almost like a replacement for the lack of top layers. This resulted in an uneven surface, which is not desirable in 3D printing.

The expected results for this project are a smooth, flat surface with no infill lines over the walls. This is because the top layers should not have infill lines, and the surface should be even and flat.

The actual results, as shown in the provided image, are quite different from the expected results. The infill is added over the walls, resulting in an uneven surface. This is not the desired outcome, and it highlights the need for a solution to this issue.

The causes of this problem are not immediately clear, but there are several potential factors that could contribute to this issue. These include:

Software Bug: The issue could be a bug in the OrcaSlicer software, version 2.2.0. This could be a result of a coding error or a misconfiguration of the software.
Printer Settings: The printer settings could be contributing to this issue. For example, the infill density or the layer height could be set too high, resulting in the infill being added over the walls.
Project File: The project file could be the cause of this issue. For example, the project file could be corrupted or contain errors that are causing the infill to be added over the walls.

There are several potential solutions to this issue, including:

Update Software: Updating the OrcaSlicer software to the latest version could resolve this issue. This would ensure that any bugs or misconfigurations are fixed.
Adjust Printer Settings: Adjusting the printer settings, such as the infill density or layer height, could resolve this issue. This would ensure that the infill is not added over the walls.
Fix Project File: Fixing the project file could resolve this issue. This would involve checking the project file for errors or corruption and making any necessary corrections.

In conclusion, the issue of infill being added over walls when no top layer is enabled is a critical problem in 3D printing. This can result in uneven surfaces and affect the overall quality of the print. By understanding the causes of this issue and exploring potential solutions, we can work towards resolving this problem and producing high-quality prints.

Based on the information provided, the following recommendations can be made:

Update Software: Update the OrcaSlicer software to the latest version to ensure that any bugs or misconfigurations are fixed.
