【3D Printing】Prusa Research Releases PrusaSlicer 2.9
Prusa has released an update to PrusaSlicer. Users can now directly distribute parts across up to nine print beds within the slicing software and utilize tools like fuzzy skin painting and scarf seams to enhance print quality.
Multi-Bed and Batch Export
You can now use up to 9 print beds in one scene! This makes it easier to work on more complex projects than ever before.
All beds share the same print settings, so you'll typically use this feature to organize multi-part prints.
If objects don't fit on one bed, the arrange tool can now distribute them across multiple beds.
Finally, a separate button has been added to arrange objects only on the active bed.
Beds are also automatically added and removed based on your interaction. Simply move an object to the space where another bed would be, and it will be generated.
Beds are always arranged in the same 3x3 grid for easier user tracking.
You can slice beds individually or simultaneously. If you choose to slice them simultaneously, you can batch export G-code or add them all to the print queue via Prusa Connect.
The export screen even provides useful statistics about overall print time and material usage.
Automatic Detection of Multiple Beds in Older PrusaSlicer Projects
PrusaSlicer has had a minimal concept of virtual beds for many years, which is evident in the arrange feature.
When too many objects couldn't fit on one bed, PrusaSlicer would keep adding them, just like other adjacent beds.
If you load such a project into PrusaSlicer 2.9.0, this situation is detected, and objects on these virtual "beds" are moved so they actually end up on non-virtual beds in the grid.
Scarf Seams
PrusaSlicer adds 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 is derived 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 marks its end, and the third marks a standard seam. The scarf seam significantly reduces the visibility of regular seams.
Printables is now a permanent option in the top bar of Prusaslicer. All users can access the option even without being logged 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 your 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 would split an object into separate regions with their own perimeters.
The new implementation, as you would intuitively expect, only affects the periphery.
At the same time, the texture quality of fuzzy skin has 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 the 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 with the height range tool, which you can use to mark boundaries for coloring.
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 quick infill).
