BedReady — 3MF Converter

Convert MakerWorld/Bambu/Prusa/Orca .3mf files for the Snapmaker U1 and other printers — in your browser, nothing uploaded.

The most complete way to make multicolor 3D-print files work on the Snapmaker U1. When you download a .3mf from MakerWorld, Bambu, Printables, or Thingiverse, it's sliced for a different printer — drop it into Snapmaker Orca and you get the wrong profile, scrambled color slots, and broken filament-change pauses. BedReady fixes all of that in one click, right on the download page. Most converters stop at swapping the profile and mapping colors. BedReady keeps going: • Swaps the foreign printer profile for the real Snapmaker U1 profile • Maps painted multicolor onto the U1's 4 slots — colors kept exactly, including text & logos • KEEPS the creator's print settings (layer height, walls, infill, speeds) — not just the colors • MORE THAN 4 COLORS: Full Spectrum reproduces extra colors by dithering 2- and 3-filament mixes • Mix from your own filaments (CMYK or any 4), with color matching tuned to what the U1 really prints • Detects height-banded models and tells you the exact filament-swap heights • Fixes the spool-swap pauses and the prime tower (the #1 cause of failed multicolor prints) It runs ENTIRELY in your browser — your file is never uploaded to a server. Free, no account. Prefer not to install? The same converter, plus a library of files with profiles tested to print on a U1, is free at bedready.io. Not on a U1? Choose your printer in the toolbar button — several Bambu Lab, Prusa and Creality multicolor printers are supported — or save a clean generic 3MF for any slicer. U1 owners can also pick their nozzle size. U1 owners can also pick their nozzle (0.2, 0.4, 0.6 or 0.8 mm). Files already set up for your printer are left exactly as downloaded, and you can switch automatic conversion off or keep the original too. Want to choose which colour goes in which slot? "Edit colours on bedready.io" opens the full editor — 3D preview, slot mapping, Full Spectrum — with your file already loaded. It is handed over inside your browser; it still never touches a server.
