When printing multiple objects at once, you can finish them sequentially, one at a time. This differs from standard printing, where all objects are built layer by layer simultaneously. The main advantages are:
- Reduced Stringing/Oozing: Less travel between parts as each is finished individually.
- Improved Layer Adhesion: Each object completes without interruption.
- Mitigates Print Failures: Failure of one part is less likely to ruin others.
- Multi-Object Vase Mode: Enables printing multiple items in vase mode sequentially.
This feature uses advanced collision avoidance automatically arranges and orders objects on the build plate in a way that the print head assembly (extruder, rods, cables) does not collide agaist already compelted objects.
Note that this is only available for supported Prusa Printers. When slicing for other printers, PrusaSlicer will fall back on generic clearance settings (Extruder clearance radius and Extruder clearance height) to define the simplified shape used for collision checks. The settings for Extruder clearance radius and Extruder clearance height are located in Printer Settings -> Sequential printing limits.
Using the feature
You can turn this feature on by enabling Print settings -> Output options -> Complete individual objects.
After that, in the Plater view, click to arrange icons or press the A key. This will automatically arrange the objects in a safe way for sequential printing.
If the items are moved and a potential collision is detected, an error message will appear identifying the affected object. The error does not block export of the G-code, but requires careful review.
Print sequence
Check the print sequence. The print order is shown top-to-bottom on the Object list. You can manually reorder by dragging items here. Press E in the 3D view to visualize the printing sequence numerically on the objects.
G-code preview
Starting from the PrusaSlicer version 2.9.1, and exclusively for Prusa Printers, you are also able to see in the preview a 3d model of the extruder by using the horizontal slider. The standard mode will only show the preview of the top layer. By clicking on the gear on the bottom right of the plater and unchecking "Sequential slider applied only to top layer", you can see the preview of the entire print project.

PrusaSlicer 2.9.2
Every G-code file contains this text at the top:
; external perimeters extrusion width = 0.40mm
; perimeters extrusion width = 0.40mm
; infill extrusion width = 0.40mm
; solid infill extrusion width = 0.40mm
; top infill extrusion width = 0.40mm
; support material extrusion width = 0.35mm
; first layer extrusion width = 0.40mm
However, if multiple platess are required and each plate is saved as a separate G-code file, this G-code file will contain the above text multiple times, one below the other, i.e., plate-1-gcode once, plate-4-gcode four times, etc.
Is this intentional?
If you really want to go above and beyond, add the ability to set automatic color changes between object prints in sequential printing. Among other things, this would make multipass first-layer color changes much easier. The current workaround requires manually editing the color changes into the G-code.
Multipass, first layer color changes allow for text and logos that are so much nicer than simple embossing without needing any kind of MMU.
Printer Settings > Custom G-codes > Between objects G-code
Be aware that this will insert the M600 command before each object starts printing. There is a risk that the print head could crash into an already printed part when it moves to the filament change position.
This is also most probably the reason why adding a color change in the usual way is not implemented
Taking it back is not on our list at the moment. The question is more about whether you achieve a successful print within the new sequential arrangement!?
It doesnt sequence anything in any proper order - it breaks and seperates into randomness and multiple plates instead of just one.
Now no visual, can't even align things manually and trying to sequence them manually is also hell.
I've wasted 4hr of my production day just trying to find HOW to place things when the auto-placement clearly demonstrates repeated FAILURE to arrange multiple items with 30mm for even a basic logical sequential print of 5 items on the Prusa mini.
👉 I've Reverted to the last version with manual placement and red spacing indication.
Glad this isn't just a "Josh" issue, because I was starting to question my existance....
Dead in the water feature for large production runs, especially if using TPU
In my case i use PS on a very very custom machine, where my active airflow on the bed is not homogenous in all location, so manual adjustment to the location and best order is a must for me.
So no, I do not achieve a successful sequential print and I don't see how I could with the new version.
As for the sequential printing its better than before seeing full tool head. But can it be optimized to allow to enter spacing (I think you could do that somewhere before). manually placing parts can do more than the automatic placement. it seemed to start at read work forward. If you start front left and work to back right tou can get a lot on a plate (even on last way before update).
fingers crossed you can added the first query.
