Veila: 3D Filament Painting

Veila turns a photo into a multicolor filament painting for your 3D printer. Thin layers of translucent filament blend into hundreds of shades: Veila picks the filaments, their order and the layers where you swap them, then makes the print files. FROM PHOTO TO PRINT IN FIVE STEPS Photo → format and size → colors → preview → print files. Every step shows a live picture of the result, so you see the painting before the printer starts. FORMATS • As photo — the whole picture with its own proportions • Aspect ratio — 1:1, 4:3, 3:2, 16:9 or A4, landscape or portrait • Shape — circle, oval or rounded rectangle • By outline — only the object, cut along its edge with a border: on a plain background, from a PNG with transparency or with AI cutout from any photo • Bookmarks — one picture cut into a set of 2–8 bookmarks with matching colors across the cuts, rounded corners and a tassel hole Size in millimetres, first layer 0.16 or 0.25 mm, the other layers 0.08 mm. YOUR FILAMENTS Keep your filaments on a shelf: color and TD (how far light goes through the plastic). Mark what is in stock, edit values or import a CSV library in the common Brand, Name, TD, Color format. SMART COLOR MATCHING Veila tests thousands of combinations and picks the filaments, their order and the swap layers that come closest to your photo. It shows how close the result is and lets you move any swap one layer up or down. LAYER-BY-LAYER PREVIEW See the print as it will look in daylight and move the slider to watch it grow layer by layer. PRINT FILES • STL — one model for any slicer, with swap instructions by layer • 3MF — a part for every filament with the filament already assigned, ready for AMS and multi-material printers in Bambu Studio and OrcaSlicer • Instructions — filaments, TD and swap layers in the same text format used on MakerWorld and Printables Save to any folder or send to your computer. FREE AND PRO Free forever: up to 4 filaments, STL files and instructions. Veila Pro ($1 a month or $10 a year) unlocks up to 16 filaments in one painting and 3MF files with filaments assigned. AI object cutout runs on our server and costs 1 credit; new users get 2 free tries. Credits are shared with other Nearfolk apps on the same phone. PRIVATE BY DESIGN No account needed. Photos, filaments and projects stay on your phone. A photo leaves the phone only when you run AI cutout, and it is not stored on the server. 8 LANGUAGES English, Ukrainian, Polish, Russian, Spanish, German, French and Portuguese. KNOWN LIMITATIONS • The preview is an estimate: real colors depend on the exact TD of your filament batch and on the light. • Filaments change by layers for the whole picture, so very colorful images come out simpler than portraits and landscapes. • In PrusaSlicer, assign filaments to the 3MF parts by hand.
