How To Remove Prime Tower Bambu Studio: A Complete Technical Guide
The prime tower in Bambu Studio can be disabled by navigating to the Global or Object-Specific settings panel under the Others tab, locating the Prime Tower section, and unchecking the Enable option. Eliminating this extrusion calibration block saves filament and reduces print time during multi-color or multi-material prints, provided your printer is properly tuned to handle the transition purge without it.
Pre-Operation & Equipment Checklist
Multi-material and multi-color 3D printing requires precise slicing parameters to ensure clean tool changes and reliable adhesion. Before modifying your slicing configuration to remove the prime tower, verify your operational parameters and hardware readiness to avoid catastrophic print failures such as nozzle clogging or severe color bleeding.
- Essential gear, tools, and materials: Bambu Lab multi-color system (AMS or AMS lite), compatible filament types (PLA, PETG, ABS, TPU), a calibrated build plate, and an active installation of Bambu Studio software.
- Mandatory prerequisite knowledge and standards: Understanding volumetric flow rates, purge volume multipliers, wipe tower mechanics, and the difference between global slicer settings and object-specific modifications.
- Estimated budget and duration benchmarks: Zero financial cost, with a processing configuration duration of less than two minutes and potential material savings of 5 to 30 grams of filament per multi-color plate.
Step-by-Step Bambu Studio Prime Tower Removal Workflow
Step 1: Open the Slicer and Access Global Settings
Launch Bambu Studio and load your multi-color project file onto the virtual build plate. Navigate to the Process panel located on the left-hand side of the user interface to access the global slicing parameters. Click on the Others tab within the process settings menu to reveal advanced configuration options related to wipe towers, resolution, and sequential printing.
Warning: Removing the prime tower globally will affect every multi-material object on the build plate. Ensure all loaded models utilize compatible materials that do not suffer from severe inter-color bleeding or poor layer adhesion.
Step 2: Locate and Disable the Prime Tower Parameter
Scroll down the Others tab until you locate the section labeled Prime Tower. Within this subsection, find the checkbox designated as Enable. Click the checkbox to toggle the setting off, which immediately removes the wireframe representation of the prime tower from the build plate preview window.
Step 3: Configure Flushing Volumes and Purge Settings
With the prime tower disabled, the print head can no longer prime its nozzle on the tower structure after a filament change. You must verify that your flushing volumes are accurately calibrated to purge old colors into the infill or into a dedicated purge chute. Navigate to the Flushing Volumes matrix button located near the filament settings in the top-left panel to fine-tune the material transition amounts, preventing color contamination in the final print.
Pro-Tip: If you experience weak layer lines immediately after a filament change, increase the flushing volume multiplier by 10 to 20 percent to ensure complete material displacement inside the melt zone before printing resumes on the exterior perimeter.
Step 4: Slice the Plate and Verify Toolpaths
Click the orange Slice Plate button in the top right corner to generate the new G-code. Once the preview screen loads, use the layer slider on the right side of the screen to inspect the toolpath. Verify that the nozzle transitions cleanly from the purge mechanism or object infill directly to the next perimeter without attempting to travel to a non-existent prime tower coordinate.

Prime Tower Versus Alternative Multi-Material Strategies
| Slicing Parameter | With Prime Tower Enabled | With Prime Tower Disabled | Optimized Hybrid Approach |
|---|---|---|---|
| Filament Consumption | High (adds 5g to 40g per plate) | Minimal (zero tower waste) | Moderate (purge into object infill) |
| Nozzle Pressure Stability | Highly stable due to consistent priming | Variable; prone to under-extrusion on first line | Stable when purge volume is sufficiently high |
| Total Print Time | Longer due to extra travel and extrusion moves | Shorter (reduces unnecessary head movement) | Balanced depending on object geometry and infill density |
| Risk of Color Bleeding | Very low | Moderate to High | Low, if flushing volume is maximized |
Common Slicing Failures and Field Fixes
- Root Cause: Under-extrusion or missing plastic immediately following a filament change when the prime tower is disabled.
- Actionable Fix: Increase the flushing volume values in the matrix settings and enable flush into object's infill and flush into object's support to absorb the transition material safely.
- Root Cause: Nozzle oozing or stringing deposited on the exterior model walls because residual pressure was not relieved on a tower.
- Actionable Fix: Adjust your retraction settings before and after tool changes, and ensure the wipe on loop feature is activated to clean the nozzle tip.
- Root Cause: Bambu Studio re-enables the prime tower automatically when switching to specialized filament profiles or complex multi-plate configurations.
- Actionable Fix: Save your custom print profile as a user preset to lock in the disabled prime tower setting across future software sessions.
Frequently Asked Questions
Can I remove the prime tower for only one specific object on the build plate?
Yes, Bambu Studio allows object-specific settings modifications. Right-click the specific model on your build plate, select Settings, and add the Others parameter group to disable the prime tower for that single model while retaining it for others.
Will disabling the prime tower cause nozzle clogs during multi-color prints?
Disabling the prime tower itself does not cause clogs, but failing to purge adequate material through the nozzle can leave residual pigment or degraded polymer that restricts flow. Ensure your purge multipliers are properly calibrated for your specific filament types.
Where does the purged filament go if there is no prime tower?
When the prime tower is removed, the printer flushes the old filament down the physical purge chute located at the rear left of the printer housing, and optionally dumps remaining transition material inside the sparse infill of the model.
Does removing the prime tower shorten total print time?
Yes, removing the prime tower eliminates the travel moves, retraction cycles, and extrusion time required to build the tower structure, which can noticeably reduce overall print duration on plates with dozens of color swaps.
Is it safe to disable the prime tower when printing with abrasive or composite filaments?
It is generally discouraged to disable the prime tower when using abrasive carbon-fiber or glass-filled filaments, as these materials require consistent pressure stabilization to prevent nozzle jamming during high-frequency retractions.
