3D Business Card Generator

Design a business card with QR code, icons and your logo and export it as STL for 3D printing

3D Print Guide

You can print multi-colored objects even with a single extruder by swapping the filament at a specific layer. The base is printed in one color, and everything that stands out above it in a second color.

  1. Generate the model and export it to STL.
  2. Open the STL in your slicer and slice it.
  3. In the layer preview, find the first layer above the base (where the raised details start).
  4. Add a filament change (PrusaSlicer, OrcaSlicer, Bambu Studio: the + next to the layer slider; Cura: Extensions → Post Processing → Filament Change).
  5. Print. The printer pauses at that layer so you can load the second filament, then continues.

Frequently Asked Questions

How thick should a 3D printed business card be?
A 1.2 mm card with 0.6 mm details feels sturdy and still fits a wallet. Use multiples of your layer height (e.g. 0.2 mm) for both values so the filament change lands exactly on a layer.
Will the QR code scan?
Yes, if the modules are big enough. Aim for at least 0.8 mm per module: use a website link instead of a full contact card, or make the code bigger. The QR tab shows a scannable preview and the module size.
Why does small text print badly?
A 0.4 mm nozzle cannot draw strokes thinner than about 0.4 mm. Use bold text, keep capitals at 2 mm or more, or print the design face down as an inlay, where the first layer gives the sharpest detail.
How do I print in several colors?
With a single extruder, add a filament change at the first layer above the base (see the print guide above). With a multi-material printer, enable "Separate parts" before exporting and assign a filament to each part in your slicer.
Which file formats can I export?
STL files (binary or ASCII) for 3D printing, and PNG images with a transparent background for previews.
Are my designs uploaded anywhere?
No. The model is generated in your browser and never leaves your computer.
