About This Tool
This tool generates watertight STL solid text, ensuring the model opens correctly in any slicer for 3D printing. The integrated base plate securely anchors free-standing letters and strokes, preventing print failures. For best results, use bold fonts as they print more reliably and produce clearer, more durable parts.
Tips
- 1STL has the widest compatibility
- 2Enable the base plate for stability
- 3Prefer bold fonts; bundled fonts only support Latin characters
About Configuration Options
Text Input
Font
DefaultHelvetiker Regular
The typeface used to generate the 3D text geometry. Different fonts produce different stroke widths and character shapes.
Helvetiker RegularRecommended
Clean sans-serif typeface, medium weight. Good all-purpose choice.
Helvetiker Bold
Bold sans-serif for sturdier, more printable strokes.
Gentilis Regular
Serif typeface, medium weight. Elegant look for badges and signs.
Gentilis Bold
Bold serif for a heavier, more readable result.
Optimer Regular
Geometric sans-serif with modern proportions.
Optimer Bold
Bold geometric sans-serif for maximum stroke strength.
Size & Ratio
Width (X)
Default30
Range5 – 100
The overall width of the text geometry in millimeters.
Height (Y)
Default6
Range2 – 50
The overall height of the text geometry in millimeters.
Depth (Z)
Default3
Range0.5 – 20 · step 0.5
The extrusion depth of the text in millimeters. Controls how far the text extends outward.
Uniform Size
Lock all three dimensions to scale proportionally, preserving the aspect ratio.
Lock Ratio
DefaultOn
Keep the width-to-height ratio fixed when resizing.
OnRecommended
Off
Orientation
Orientation
DefaultUpright
Choose whether the text stands upright or lies flat for 3D printing.
UprightRecommended
Text extends upward from the build plate. Best for nameplates and signs.
Flat
Text geometry lies flat. Useful for inlay designs and flat badges.
Position Offset
Offset X
Default0
Range-50 – 50 · step 0.5
Move the text geometry left or right on the X axis.
Offset Y
Default0
Range-20 – 50 · step 0.5
Move the text geometry up or down on the Y axis.
Offset Z
Default0
Range-20 – 20 · step 0.5
Move the text geometry forward or backward on the Z axis.
Bevel
Bevel Thickness
Default0.5
Range0 – 3 · step 0.1
Controls how much the edges of the text are rounded. Adds a polished look but increases face count.
Bevel Segments
Default3
Range1 – 8
The number of segments used to create the bevel curve. More segments produce smoother bevels at the cost of more geometry.
Base Plate
Base Height
Default2
Range0.5 – 20 · step 0.5
The thickness of the base plate beneath the text. A thicker base provides more stability and keeps letters attached.
Base Padding Width
Default2
Range0 – 20 · step 0.5
Extra horizontal margin around the text on the base plate.
Base Padding Depth
Default2
Range0 – 20 · step 0.5
Extra vertical margin around the text on the base plate.
Base Bevel
DefaultOff
Whether to round the edges of the base plate.
OffRecommended
On
Base Bevel Radius
Default0.3
Range0.1 – 3 · step 0.1
The radius of the base plate corner rounding.
Base Bevel Segments
Default2
Range1 – 8
The number of segments for the base plate bevel curve.
Colors
Text Color
Default#3b82f6
The color of the extruded text geometry. For 3MF and GLB, this color is preserved in the output file.
Base Color
Default#9ca3af
The color of the base plate. Only preserved in 3MF and GLB output formats.

Frequently Asked Questions
About this tool
Q
Why is STL commonly used for 3D printing text?
A
STL is the most widely supported print format, and the exported watertight mesh is ready to slice directly.
Q
How to make 3D letters print more reliably?
A
Use a bold font, enable the base plate, apply a modest bevel, and use sufficient extrusion depth. These settings keep thin strokes and small letters firmly attached to the base plate, so they are much less likely to peel off or break during printing.
Q
Are the letters and base plate one piece?
A
Yes. They are exported as a connected watertight mesh, with the strokes attached to the base plate.
Q
Can I use any font from my computer when creating text-to-STL models?
A
No. Only six bundled Latin fonts are available (Helvetiker, Gentilis, and Optimer: regular and bold). There is no system-font picker and no custom font upload. Characters outside the selected font (including CJK) are skipped.
Q
How smooth are curved letters in the exported STL?
A
STL stores surfaces as flat triangles, so curves are approximated by segments: the letter outlines are generated with smooth curve tessellation, which looks clean at typical print sizes. Bevel segments (1-8) control the smoothness of rounded edges; more segments mean smoother bevels but larger files.
Q
What is the smallest text size that still prints well?
A
There is no fixed minimum, but legibility depends on stroke width versus your nozzle: with a 0.4 mm nozzle, strokes below roughly 0.8-1 mm tend to fail. Choose a bold font and keep the letter height at least a few millimeters for clean small prints.
General questions
Q
Is Any3D completely free?
A
Yes, Any3D's core features are free to use forever. We provide format conversion, model optimization, and online preview at no cost, with no registration required.
Q
Are my files uploaded to your servers?
A
No. Files you select are processed only in your browser on this device, so they never leave your device and are never sent to our servers. We don't store any user files; after processing, related data in browser memory is released.
Q
Do I need to install software?
A
No installation required. Any3D is entirely browser-based; just open the webpage to use all features. It works on Windows, Mac, Linux, and other major operating systems.
Q
Is there a file size limit?
A
The processing capacity depends on your device performance and the model's vertex count and texture complexity, rather than file size alone. We impose no file size limit, but when a model exceeds what your device can handle, the page may lag or even crash.
