Send your parametric solids, meshes and assemblies directly from FreeCAD to SimplyPrint for slicing and printing

## About

The SimplyPrint addon for FreeCAD bridges the gap between parametric CAD and 3D printing.
Model in FreeCAD, then send your work straight to your printer in a single click - no separate mesh export step, no juggling files between programs.

The addon adds a context-aware **SimplyPrint** dock panel that adapts to the workbench you're in - pick solids in **Part** or **Part Design**, send meshes as-is from the **Mesh** workbench, or push a whole **Assembly** as one file. It also installs a dedicated **SimplyPrint** workbench with a toolbar and menu for one-click access from anywhere.
Pick **STL**, **3MF** or **OBJ**, choose mesh quality, hit **Send to SimplyPrint**, and SimplyPrint opens in your browser with the model loaded - ready to slice, queue, or print.





#### How to install

##### Option 1 - FreeCAD Addon Manager (recommended)




- In FreeCAD, go to **Tools → Addon Manager**.

- Search for **SimplyPrint** in the list and click **Install**.

- Restart FreeCAD - the **SimplyPrint** dock panel and workbench appear.


##### Option 2 - Manual zip install (Windows, macOS, Linux)




- Download the zip:
[
** Download SimplyPrint.zip
](https://cdn.simplyprint.io/i/static/integrations/freecad/SimplyPrint.zip)

- Find your FreeCAD user Mod/ folder - open FreeCAD's Python console (**View → Panels → Python console**) and run App.getUserAppDataDir(). The addon goes in the Mod subfolder of that path.

- Extract the zip into that folder so you end up with Mod/SimplyPrint/.

- Restart FreeCAD.




#### Getting started

The **SimplyPrint** dock panel docks on the right of the FreeCAD window (available in every workbench).
Click **Log In** the first time - a browser tab opens, you approve the request, and you're set for future sessions.

Open or model something with solids or meshes - the panel shows the objects it found, the mesh-quality options for solids, and the real bounding box and volume.
Choose a format and mesh quality, tick the objects to send, and click **Send to SimplyPrint**.
Your browser opens SimplyPrint with the file loaded, ready to slice, queue, or print on one or more printers.
