【3D Printing】Prusa Research Releases PrusaSlicer 2.9
Prusa has released an update to PrusaSlicer. Users can now distribute parts across up to nine print beds directly in the slicer software and utilize tools like fuzzy skin painter and scarf seams to improve print quality.
Multi-Bed and Batch Export
You can now use up to 9 print beds in a single scene! This makes it easier than ever to handle more complex projects.
Additionally, all beds share the same print settings, so you'll typically use this feature to organize multi-part prints.
The arrange tool can now distribute objects across multiple beds if they don't fit on a single one.
Finally, a separate button has been added this time to arrange objects only on the active bed.
Beds are also automatically added and removed based on your interaction. Simply move an object into the space where another bed would be, and it will generate.
Beds are always arranged in the same 3x3 grid for easy user tracking.
You can slice beds individually or simultaneously. If you choose to slice beds simultaneously, you can batch export G-code or add all of them to the print queue via Prusa Connect.
The export screen even provides useful statistics on overall print time and filament usage.
Automatic Detection of Multiple Beds in Older PrusaSlicer Projects
PrusaSlicer has had a minimal concept of virtual beds for many years, which was evident in the arrange functionality.
When there were too many objects to fit on one bed, PrusaSlicer would keep adding them as if they were other beds adjacent.
If you load such a project into PrusaSlicer 2.9.0, this situation will be detected, and the objects on these virtual "beds" will be moved so they actually end up on non-virtual beds in the grid.
Scarf Seams
PrusaSlicer has added a new seam option called "scarf seam."
Its main purpose is to hide visible seams on smooth edges of objects, which is achieved by overlapping extrusions at the start and end of the perimeter loop.
The name of this feature comes from a similar technique in woodworking called a "scarf joint."
In the example above, the cylinder is printed with both regular and scarf seams.
The first marker indicates the start of the scarf seam, the second marker is the end position, and the third marker is a standard seam. Scarf seams significantly reduce the visibility of regular seams.
Printables is now a permanent option in the top bar of Prusaslicer. The option is available to all users, even without logging in.
Similar to the web version, you can browse 3D models in the Printables tab and seamlessly open them on the Plater tab using the Slice button with the Printables logo, or send the G-code directly to your printer via Prusa Connect.
Fuzzy Skin Painting
The new fuzzy skin painting tool available in the left toolbar allows you to easily add fuzzy skin to specific parts of an object without using modifiers.
It features several brush types and smart fill tools similar to the multi-material tool and support painting tool.
This new tool complements the overall effect of fuzzy skin generation.
Previously, it split an object into separate regions with their own perimeters.
The new implementation works as you would intuitively expect, only affecting the perimeter.
At the same time, the texture quality of fuzzy skin has also been improved.
Improvements to Painting Tools and Multi-Material Slicing
A height range tool has been added to multi-material painting, allowing you to create perfect horizontal color stripes across an entire object.
The bucket tool has also been improved and now includes a fill angle setting, similar to the smart fill tool.
This works very well in conjunction with the height range tool, which you can use to mark borders for coloring.
The handling of painted models has been improved, and various types of artifacts have been fixed.
This means that sliced models will now better match how they were painted.
Support for Printing with Different Nozzle Diameters
Experienced users and developers can now print with different nozzle diameters on multi-extruder printers (such as the Original Prusa XL).
This workflow allows combining nozzles of different diameters (e.g., a smaller nozzle for fine details and a larger nozzle for fast infill).
Please check the PrusaSlicer release page for more details on the features mentioned above and a complete list of all changes and bug fixes.
