mc-print

What is mc-print?

mc-print turns a zone of your own Minecraft Java world into a multicolor 3D print. You open the world folder, or a .zip of it, in the browser, draw a zone on a zoomable top-down map or type its block coordinates, check it in a 3D preview and export. The world is read on your computer and never uploaded. The first visit downloads about 16 MB of app code, which is then cached.

There are three color modes: 4 colors maps every block to the nearest of four filaments (picked for you or set by hand), Full Spectrum adds the mixed filaments of Snapmaker Orca, and All colors is for looking only and cannot be exported. You set the mm per block (2 mm by default) or fit the zone to the print bed, a top Y limit, vertical scale, base and color depth, and choose whether bridges and overhangs float (print with supports), only trees float, or everything is filled solid. Filament 4 can be kept for soluble PVA support. Zones go up to 400 blocks per side, and Java worlds from 1.12 and older or 1.18 and newer are supported; 1.13 to 1.17 worlds have to be opened once in 1.18 first.

Export 3MF gives a Snapmaker Orca project for the Snapmaker U1 with the parts already assigned to filaments. For other printers, the STL zip holds one STL per filament to load as parts of one object in your slicer. It is free, with no account and a Ko-fi tip link. The code is open source under the MIT license, which covers the software, not your prints, and the site says nothing about selling them. It suits Minecraft players with a multi-material printer who want a build or a landscape on the shelf.
