Generate a scannable QR code and brand artwork for Reaudit.io, all in your browser. This is Feature 5 of 69 in the 3DPlotter V3 series: a walkthrough of the QR Code tool. Add 3D Letters, encode the reaudit.io URL as a plot-ready QR code, type the tagline "brand visibility for the agentic era", frame it with Offset, and export G-code for your 3D printer. No Inkscape, no external QR generators.
What you'll see in the video
- Add Object → Shapes & Imports → QR Code with URL, plain text, vCard, WiFi, email, phone, SMS, or location payloads
- Build Reaudit artwork: 3D Letters for REAUDIT.IO and a square-module QR linking to reaudit.io
- Put the QR on its own layer so it does not inherit an Offset modifier from the frame
- Frame the code with Offset on a rectangle and add the tagline in Text
- Assign pen colours per layer and export for multi-pen plotting
- Watch the plot: QR pass, frame, then lettering
How to use QR Code
- Open Studio → Add Object → Shapes & Imports → QR Code
- Enter URL, contact, or WiFi payload in the right sidebar
Menu path: Add Object → Shapes & Imports → QR Code
The story behind this plot
This piece is a thank-you to Reaudit, the AI visibility platform I also founded. Without any social media, Reaudit helped 3DPlotter reach $10,500 in revenue in seven months. This plot puts that story on cardstock: REAUDIT.IO in 3D letters, a scannable QR code linking to reaudit.io, and the tagline "brand visibility for the agentic era" in single-stroke text.
Three layers, two pens, one scannable artwork: 3D Letters for the logo, QR Code for the link, Text for the message, and an Offset frame around the code.
QR Code features
- URL, contact & WiFi: encode links, vCards, and WiFi login payloads
- Live preview: slider and setting changes update the board instantly
- Module styles: square, rounded, or dot modules for different plot aesthetics
- Error correction: choose L, M, Q, or H for scan reliability vs. density
- Fill spacing: optional hatch fill between modules for bolder plots
- Edge-to-edge modules: QR paths reach the bounding box for clean framing
- One layer entry: each QR code is a named, editable element in the stack
- Direct G-code export: PlotFlow Engine outputs pen-optimized paths for your specific printer
Why QR Code beats external generators
Most workflows mean generating a QR in a website, exporting a bitmap, tracing it in Inkscape, and hoping the modules still scan. 3DPlotter generates vector module paths live on the bed, pairs them with 3D Letters and Text on the same board, and exports G-code in one place.

What you can plot with QR Code
- Scannable QR codes linking to websites, contact cards, and WiFi networks
- Brand artwork combining QR codes with 3D Letters, Text, and Offset frames
- Multi-pen plots on Bambu Lab, Prusa, Creality, and other pen-holder setups
- Layered linework exported as G-code with pen-up travel
- Business cards, stickers, posters, and promotional art on one board
Frequently asked questions
How do I add a QR code to a pen plot in 3DPlotter?
Add Object → Shapes & Imports → QR Code, enter your URL in the inspector, and click Generate. The code appears as editable vector paths on the canvas.
Will a pen-plotted QR code still scan?
Yes. When module size and error correction are set appropriately, use the live preview to check density, then test-scan before plotting at full scale.
Can I combine a QR code with text and 3D letters?
Yes. Each object lives on its own layer or element in the stack. This walkthrough combines QR Code with 3D Letters, Text, and an Offset frame.
What can I encode besides URLs?
Contact cards (vCard), WiFi login credentials, and plain text. Switch payload type in the QR Code inspector.
Does the QR code update when I change settings?
Yes. Size, module style, and error correction update the board live. No need to regenerate from an external tool.
Does QR Code work with multi-pen plotting?
Yes. Use Pen Palette on a layer to split linework by colour, or assign per-path ink to different elements.
