Photo to Relief & Multicolor
Turn a logo, drawing or photo into a raised relief, a heightmap or a multicolour picture made from stacked filament layers. This category covers SVG to STL converters, heightmap tools and filament-painting apps such as HueForge.
For filament painting you need several filament colours and a printer that can pause or swap filament. The result looks like a painted picture straight off the build plate.

Printing image to 3d: 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.
Matte PLA for signs and Gridfinity
Matte filament hides layer lines and cuts glare, so raised lettering on signs and nameplates stays readable from any angle and a drawer full of bins looks uniform.
- Bambu Lab PLA MatteWide colour range with AMS-ready RFID, ideal for multi-colour signs.
- Polymaker Panchroma Matte PLA (formerly PolyTerra)The former PolyTerra line under a new name: soft matte look and good value for printing Gridfinity in bulk.
- SUNLU Matte PLALow-cost matte option for large batches of bins and baseplates.
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.
- Bambu Lab AMS liteFour-spool open unit for the A1 series; the cheapest way into Bambu multicolour.
- Bambu Lab AMS 2 ProEnclosed four-spool unit with built-in filament drying for Bambu's enclosed printers.
- Creality CFS (Creality Filament System)Creality's multicolour unit for K2-series printers; expands to 16 colours with RFID and moisture-proof storage.
