QR, Spotify & NFC Codes
A printed QR code still scans, as long as the contrast is good. These tools turn a link, a Wi-Fi password or a Spotify song code into a two-colour model, and some add a slot for an NFC tag so phones can tap instead of scan.
Use two strongly contrasting colours (black on white works best) and a 0.4 mm nozzle or smaller for crisp modules.

Printing codes: what to buy
The generator does the design. These materials make the print look as good as the preview.
Multicolour PLA for keychains and HueForge
Dual- and tri-colour silks give a single-nozzle printer colour shifts with no extra hardware, and a matched colour set is what lets HueForge and colour lithophanes blend thin layers into a full image.
- Bambu Lab PLA Silk Multi-ColorCo-extruded dual and tri colours that shift with the viewing angle; great for keychains and name tags.
- SUNLU Multi-Color Silk PLA (dual/tri/four-colour)Budget dual-, tri- and four-colour silk for colourful prints without an AMS.
- Bambu Lab PLA CMYK Lithophane BundleFour 1 kg spools (cyan, magenta, yellow, white) made for colour lithophanes and handy for HueForge-style layering.
NFC tags to embed in prints
An NFC tag hidden under a few layers turns a sign or keychain into a tap-to-open link, Wi-Fi card or contact card. NTAG215 has room for URLs and works with almost every phone.
- Bambu Lab NFC Tag Sticker (20 pcs)NTAG215 chips, rewritable, 20 per pack, for embedding mid-print.
- Timesetl NTAG215 round NFC stickersLow-cost NTAG215 stickers in bulk, programmable with free phone apps.
Multicolour filament systems
An automatic filament changer prints multi-colour signs, keychains and HueForge pieces without you standing by to swap filament at every colour layer.
