Earns its place by pulling the 3D printing pipeline into a single Blender addon, covering painting, supports, slicing and export rather than spreading the work across separate apps.
3D Maker - The Complete 3D Printing Workflow Suite turns Blender into a 3D printing workstation, covering steps from model preparation through export without leaving the software. It targets both FDM and resin printing workflows.
The suite bundles a wide set of tools. You can paint vertex colors in Sculpt Mode with gesture-based selection (Lasso, Box, Polyline and Circle), including opacity blending and front-face-only filtering with occlusion, plus a palette manager to save and reuse color sets. A Support Generator builds cylindrical or rectangular supports from an overhang angle, while the Print Simulator previews layer lines and silk finish in the viewport with a procedural material. Boolean operations run non-destructively with live preview, and a Pin & Joint System creates parametric connectors and male/female joints. Alignment, Explode View, Scale to Real Size, Normals Manager and a Printer Volume Manager round out the set.
Send to Slicer pushes models to Bambu Studio, Orca Slicer, PrusaSlicer, Ultimaker Cura, ChiTuBox, Creality Print or Lychee Slicer in one click, auto-detecting installed slicers. Objects export to STL or OBJ with vertex colors preserved. The interface is bilingual English and Spanish, switchable from preferences, and it runs on Windows, macOS and Linux under a GPL license.
3D Maker - The Complete 3D Printing Workflow Suite is best for makers and 3D printing enthusiasts working in Blender, product designers preparing models for physical production, and miniature or figurine creators who need precise scale control.
3D Maker - The Complete 3D Printing Workflow Suite is completely free to download and use.
3D Maker lists compatibility with Blender 4.3 through 5.0 and requires Python 3.10 or newer. It runs on Windows, macOS and Linux, so the three major desktop platforms are covered. Because supported ranges can shift as Blender releases new builds, it's worth checking the developer's page to confirm your exact version before installing, especially if you're on a very new or older release of Blender.
3D Maker can send models to Bambu Studio, Orca Slicer, PrusaSlicer, Ultimaker Cura, ChiTuBox, Creality Print and Lychee Slicer through its Send to Slicer feature. It auto-detects slicers already installed on your system, so the export happens in one click. Alongside slicer export, the addon can also write each selected object to individual STL or OBJ files, preserving vertex colors and using your project folder for path detection.
3D Maker is listed as free in this catalog. Licensing terms can change over time, so it's worth checking the developer's page for the current details before you download. The addon is distributed under a GPL license, which is common for Blender add-ons and governs how the code can be used, modified and shared. For anything specific to your situation, the developer's page is the best reference.
3D Maker ships with a full bilingual interface in English and Spanish. You can switch the language instantly from the addon preferences, and when you do, all panel titles, buttons and messages update immediately. Because the switch happens from preferences, you can move between the two languages at any point while working. The bilingual coverage applies to the interface itself, so the panels for tools like vertex color painting and Send to Slicer display in whichever of the two languages you have selected.
