How to Print Your Custom Card

A 3D-printed card has its own thickness, which can be adjusted to your needs. The most important part is the BEVEL—this defines the actual borders and text.

• ✔ The bevel height should always be greater than your layer height.
• ✔ If your printer has a 0.2mm layer height, set the bevel to at least 0.6mm for a crisp finish.
• ✔ A bevel height above 2mm can look bulky, but it’s a personal choice.

Fonts & Readability

We use Hershey Fonts, originally designed for CRT screens in the 1970s. These fonts work great for 3D printing due to their clear, simple lines with minimal detail.

Bold / Medium / Light – Which to Choose?

• ✔ Bold – Best for clarity and high readability. (Recommended ✅)
• ✔ Medium – Works well but may be harder to read at smaller sizes.
• ✔ Light – May be too thin for printing, especially on smaller cards.

Tip: If the text disappears in the slicer preview, switch to a bolder font or increase the size!

Braille

Making a card with Braille can be helpfull to label / tag items. It was an afterthought but a logical one; a 3D printed card is a perfect medium for braille.

Slicing Your STL File

Before printing, check your slicer preview:

• ✔ Ensure all elements (borders, text) are visible in the slice.
• ✔ If small text does not appear, it may be too thin to print with your current slicer settings.
• ✔ Adjust either the font size or your slicing settings accordingly.

Common Fixes:

• 🔸 Increase the font size
• 🔸 Use the Bold font
• 🔸 Reduce the layer height in the slicer

Printing with Color Changes

To make your card more readable, add a filament change when your printer starts printing the border/text layers.

💡 Most slicers support this feature!

• ✔ In PrusaSlicer, Cura, or SuperSlicer: Use the "Pause at Layer" or "Filament Change" feature.
• ✔ Set the change point just before the text begins printing.
• ✔ This allows for a contrasting color for the text, making it stand out!

Final Tip: Experiment with different color combinations for maximum contrast and readability. 🎨
