Spiralist is a free site that redraws a photo as one continuous line. I just added a 3D print option, and since the drawing is one unbroken line, it prints as one piece. You can print it four ways: - Wire sculpture: the drawing itself, printed flat at 1.6 x 2.4 mm with 100% infill. It hangs from a small loop or stands in a printed base. A 150 mm portrait is about 45 min and under 10 g on my A2L. - Lithophane: 0.8 to 3.2 mm thick, printed standing with a brim and 100% infill. About 2 hours. - Relief plaque: the line raised 1.2 mm on a 2.4 mm plate with a frame. Two colours with an AMS or a filament swap at Z 2.4 mm. About 1.5 hours. - Cookie cutter and stamp: the outline of the subject in the photo (found by a small segmentation model, not just the edge of the drawing), a 0.8 mm cutting edge flaring to 2.4 mm, 12 mm tall, plus a stamp with the drawing mirrored and a push-fit handle. About 40 min. Details you might care about: - Lines under 0.8 mm (two perimeters on a 0.4 nozzle) get thickened and gaps under 0.5 mm get merged, and it tells you what it changed. If a drawing is too dense for a product (a tight spiral as a wire just fuses into a disc), that product isn't offered. - Export is STL per part, or 3MF with the parts coloured, print settings per object (infill, walls, brim) and a second plate when things don't fit. - Presets for Bambu A1 mini, A1, A2L, P1S and X1C, Prusa MK4 and MINI+, Ender-3 and a generic 220 x 220 bed. It warns you when a part doesn't fit. - Every file is checked for being watertight, and while building it I ran every product through Bambu Studio's command-line slicer on the A2L profile to make sure they slice. - "Watch it print" makes a timelapse video of your printer building the part: walls, infill, the colour change. It's a simulation. Its time estimate lands within about 5% of Bambu Studio's for the plaque and the lithophane, and it runs low on the wire. You can also drop in a G-code file you sliced yourself and it replays the real toolpaths. Not solved yet: - Bambu Studio's command line ignores colour changes, so for two colours you set the swap in Bambu Studio yourself. The tool tells you which layer. Everything is open-sourse! Live on Github pages: https://winchxyz.github.io/spiralist/ Github repo: https://github.com/winchxyz/spiralist I built it with Claude Code, in case that matters to anyone. The drawing and the print files are plain code. The only AI parts are small models that find the lines and the subject, used for the Line art mode and the cookie cutter. If you print one I'd love to see it, especially the wire ones.   submitted by   /u/oxmannnn   to   r/3Dprinting [link]   [comments]
