3D Printing Text on Objects in Bambu Studio: A Guide for Educators
Introduction
Adding text to 3D printed objects opens up countless possibilities for classroom manipulatives, labeled tools, personalized projects, and student learning aids. Whether you’re creating vocabulary flashcards with Spanish words, math manipulatives with printed numbers, or labeled classroom equipment, Bambu Studio makes it surprisingly straightforward to add professional-looking text to your 3D prints.
This guide walks you through three distinct techniques for adding text to objects in Bambu Studio, using a practical example: creating educational manipulatives with Spanish vocabulary words printed directly on them. Each technique offers different visual effects and durability characteristics, giving you the flexibility to choose the best approach for your specific classroom needs.
What You’ll Learn
By the end of this guide, you’ll know how to create:
- Raised text with color changes - Text that sits on top of your object with contrasting colors
- Negative (recessed) text - Text cut into the surface for durability
- Flush text using modifiers - Multi-colored text that’s perfectly level with the surface
You’ll also discover that these techniques extend far beyond text—they’re powerful tools for customizing any aspect of your 3D prints.
The Example: Spanish Vocabulary Manipulatives
Throughout this guide, we’ll use a concrete example: creating classroom manipulatives with Spanish object names printed on them. This practical application demonstrates how each technique works while showing you something you can immediately adapt for your own classroom—whether that’s vocabulary in any language, student names, mathematical symbols, or labeling systems.
Technique 1: Raised Text with Color Change
When to Use This Technique
Raised text with a color change creates bold, eye-catching labels that stand out visually. This is ideal when you want maximum visibility and contrast, such as vocabulary words that students need to read easily from a distance or manipulatives where the text needs to be the focal point.
The Process
Creating raised text in Bambu Studio is remarkably simple:
- Load your base object into Bambu Studio
- Select the Text tool and click on a flat surface of your object
- Type your text (for example, “libro” for a book-shaped manipulative)
- Adjust the text size using the built-in text height tools
- Position the text using the move tool

The text will automatically sit on top of your object as a raised element. You can adjust its position by dragging it visually or using more precise methods (covered in the Alignment section below).
Adding the Color Change
To make your text stand out with a different color:
- Slice your model in Bambu Studio
- Identify the layer where you want the color change to occur (typically when the text layer begins)
- Insert a manual filament change at that layer using the layer pause feature
- When printing, the printer will pause at the designated layer, allowing you to swap filament colors

This creates a dramatic visual effect where the text appears in a contrasting color against the base object—perfect for making vocabulary words or labels immediately noticeable.
Technique 2: Negative (Recessed) Text
When to Use This Technique
Negative text is cut into the surface of your object rather than sitting on top. This technique is particularly valuable for classroom manipulatives that will get heavy use, since recessed text won’t wear down, break off, or get damaged through repeated handling. It’s also aesthetically clean and professional-looking.
The Process
Creating negative text requires one additional step beyond basic text placement:
- Create your text using the Text tool (same as Technique 1)
- Adjust the text depth using the text depth tool—make sure your text has sufficient depth to cut meaningfully into the object
- Change the object type from a regular shape to a negative shape

When you slice the model, the text area will now be subtracted from your base object, creating a recessed impression.
The Power of Negative Shapes
Here’s an important insight: any shape can be a negative shape, not just text. This means you can use this technique to create recessed logos, custom cutouts, tactile patterns, or any design element you can imagine. For educators, this opens up possibilities like creating puzzle pieces with interlocking negative spaces, relief maps with recessed features, or sensory learning tools with varied surface textures.
Technique 3: Flush Text with Modifiers
When to Use This Technique
Flush text creates the most polished, professional appearance—text that’s perfectly level with the surface but in a different color. This technique is ideal when you want clean aesthetics without raised or recessed elements, such as labels on storage containers, nameplates, or display models.
Requirements
Important: This technique requires an AMS (Automatic Material System) to automatically switch between different filament colors during the print.
The Process
Modifiers work differently from the previous two techniques—instead of making the text a physical addition or subtraction, you’re modifying how that specific area of the object is printed:
- Create your text using the Text tool
- Change the object type to “modifier” (instead of regular shape or negative shape)
- Select what you’re modifying—in this case, the filament color
- Choose your alternate color for the text area
[Screenshot: Setting an object as a modifier and selecting filament color modification]
When sliced, the printer will automatically switch filaments in the text area, creating multi-colored text that’s completely flush with the surface. The result is seamless and highly professional.
Beyond Color: The Versatility of Modifiers
Modifiers are one of Bambu Studio’s most powerful features. While we’re using them for color changes in text, you can modify much more:
- Infill type: Make certain sections of an object use different infill patterns (hexagonal vs. grid, for example)
- Infill density: Create areas of higher or lower density for structural reinforcement or material savings
- Print settings: Adjust speeds, temperatures, or other parameters for specific regions
For classroom applications, imagine creating a manipulative where certain sections are more rigid (high infill) while others are flexible (low infill), or a model with strategic reinforcement in high-stress areas. These techniques have applications far beyond text.
Getting Alignment Right: The Manual Coordinate Approach
One of the trickiest aspects of adding text to objects is getting it perfectly centered and positioned. Initially, you’ll likely eyeball the placement by dragging text around visually. However, there’s a much more precise method that will save you time and frustration once you learn it.
The Centering Technique
- Select your text element
- Open the Move tool
- Set the coordinates to “relative to object” (not absolute coordinates)
- Manually adjust the X and Y coordinates to 0
This centers your text directly on the object. From here, you can make fine adjustments:
- Increase or decrease the Y coordinate to move text up or down with precision
- Adjust X for left/right positioning
- Keep spacing uniform when adding multiple text elements

Learning Curve Tip
Alignment is something teachers initially figure out through trial and error—eyeballing and adjusting until it looks right. But encourage yourself (and your students, if they’re designing) to transition to manual coordinate adjustment as soon as possible. This approach gives you precise control, makes it easy to replicate positioning across multiple objects, and eliminates the guesswork.
Tips for Success
Font Considerations
While Bambu Studio supports various fonts, simpler sans-serif fonts generally print more reliably than decorative or serif fonts, especially at smaller sizes. For classroom manipulatives, prioritize readability over style.
Text Size and Depth
- Make text large enough to be easily legible when printed—test prints are your friend
- For raised text, ensure adequate height so it doesn’t disappear during printing
- For negative text, ensure sufficient depth to create a visible impression
- Start with modest dimensions and adjust based on results
Surface Considerations
These techniques work best on flat or gently curved surfaces. Highly curved or irregular surfaces may require more advanced positioning or alternative approaches.
Beyond Text: Broader Applications
While this guide focuses on adding text to objects, remember that these techniques have countless other applications:
- Negative shapes can create custom cutouts, ventilation holes, allow for embedded objects, snap-fit connections, or decorative patterns
- Modifiers can strategically reinforce structures, reduce material use in non-critical areas, or create multi-material effects
- Color changes can add visual interest to any layer of any print, not just text layers
As you become comfortable with these tools for text, start exploring how they might solve other design challenges in your classroom projects.
Conclusion
Adding text to 3D printed objects in Bambu Studio is more accessible than many educators realize. With just three core techniques—raised text with color changes, negative recessed text, and flush text with modifiers—you can create professional-looking, durable educational materials customized for your classroom needs.
The Spanish vocabulary manipulatives example we’ve used throughout this guide is just one starting point. These same techniques apply to:
- Student name labels for personal storage or tools
- Mathematical symbols on geometry manipulatives
- Phonics letters on tactile learning aids
- Labeled parts for science models
- Customized game pieces with player names or teams
Start with one technique, experiment with a simple project, and gradually explore the others. The investment in learning these skills opens up a world of customization possibilities for your classroom.
What’s Next?
Once you’re comfortable with Bambu Studio’s built-in text tools, you might want to explore even more advanced customization through OpenSCAD, a script-based modeling approach that offers parametric control over text and shapes. This allows you to create templates where you can automatically generate entire sets of manipulatives just by changing variables—imagine typing a list of names and having OpenSCAD automatically generate 30 labeled, personalized objects ready to print. That’s a topic for a future guide, but it’s worth knowing that your 3D printing journey has many more powerful techniques to discover.
