About This Tool

Generate watertight STL solid text that opens cleanly in any slicer. The built-in base plate anchors free-standing strokes so thin parts stay in place, and bold fonts print more reliably. Ideal for nameplates, signs, and dimensional lettering.

Tips

  • 1STL has the widest printer compatibility
  • 2Turn on the base plate for a sturdier print
  • 3Prefer bold fonts; bundled fonts cover Latin characters only

About Configuration Options

Text Input

Text

DefaultAny3D.cc

The text content to convert into a 3D model. Multi-line text is supported.

Font

DefaultOswald (Display Bold)

The typeface used to generate the 3D text geometry. Different fonts produce different stroke widths and character shapes.

Oswald (Display Bold)Recommended

Condensed display sans with strong strokes, good for titles and 3D printing.

Inter (Modern Sans)

Neutral modern sans for readable body text and UI-like labels.

Show 4 more options
Cinzel (Classic Serif)

Classic serif for premium badges, plaques, and heritage labels.

Roboto Mono (Engineering)

Monospace for dimensions, SKUs, and technical callouts.

Noto Sans SC (CJK)

Sans covering Simplified Chinese, Japanese, and Korean glyphs.

Noto Sans Arabic

Sans covering Arabic script with print-ready stroke weight.

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.

Description:
STL is the de facto standard mesh format in 3D printing, storing only triangular surface data since 1987, without color, texture, or material. Almost all slicers (Cura, PrusaSlicer, Bambu Studio, ChiTuBox) and printers directly support STL, ensuring its enduring popularity. Two classic pitfalls: STL lacks unit definitions, making millimeters and inches indistinguishable on disk; always verify scale in your slicer. It also has ASCII (readable but 4-6x larger) and binary (compact, default) encodings. For multi-color printing, materials, or parameters, switch to 3MF, which carries richer print information while maintaining slicer compatibility.

Notes:

  • Does not support colors, textures or materials
  • No unit definition; verify scale in your slicer
  • ASCII format is 4-6× larger than binary

Supported Features:

  • Triangle mesh only, simple and universally compatible
  • Binary and ASCII encoding options
  • Directly importable into Cura, PrusaSlicer, Chitubox, etc.

Frequently Asked Questions

About this tool

Q

Why is STL the go-to format for 3D printing text?

A

STL is the most widely supported format in slicing software. This tool exports a watertight mesh, so you can hand it straight to Cura, PrusaSlicer, or Bambu Studio without repair or conversion.

Q

How do I make 3D letters print more reliably?

A

Use a bold font, enable the base plate, set a moderate bevel, and choose enough extrusion depth. These settings keep thin strokes and small letters firmly attached to the base plate, reducing the chance of peeling or breaking during printing.

Q

Are the letters and base plate a single piece?

A

Yes. The text and base plate are exported as one connected watertight mesh, with every stroke attached to the base plate. That makes the model easy to slice and print as a single object.

Q

Can I use a font from my computer when making text-to-STL models?

A

No. Only six bundled Latin fonts are available (Helvetiker, Gentilis, and Optimer in regular and bold). There is no system font picker and no custom font upload. Characters outside the selected font, including CJK glyphs, are skipped.

Q

Are curved letters smooth in the exported STL?

A

STL stores surfaces as flat triangles, so curves are approximated by segments. Letter outlines are generated with smooth curve tessellation, which looks clean at typical print sizes. The bevel segments control (1-8) sets the rounded-edge smoothness: more segments give smoother bevels but larger files.

Q

How small can text be and still print clearly?

A

There is no fixed minimum, but legibility depends on stroke width compared to your nozzle. With a 0.4 mm nozzle, strokes below roughly 0.8-1 mm tend to fail. Pick a bold font and keep the letter height at least a few millimeters for crisp small text.

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.
