# 3D print directly from SolidWorks - export, slice and print in one click

**Categories:** Third party, Verified

**Developer:** [SimplyPrint](https://simplyprint.io)
**Launched:** Jul 14, 2026

Send your CAD models directly from SolidWorks to SimplyPrint for slicing and printing

## About

The SimplyPrint add-in for SolidWorks bridges the gap between CAD design and 3D printing.
Model in SolidWorks, then send your part or assembly straight to your printer in a single click - no separate export step, no juggling files between programs.

The add-in adds a **SimplyPrint** tab to the right-hand **Task Pane**, plus a toolbar button and a **Tools → SimplyPrint** menu entry.
Pick **STL** or **3MF**, choose which configuration, bodies or components to export, dial in the mesh quality, hit **Send**, and SimplyPrint opens in your browser with the model loaded - ready to slice, queue, or print.


**

The add-in runs on **Windows** (SolidWorks itself is Windows-only). Install it with the Windows installer below, or register it manually using the zip - the steps for both are below.





#### How to install

##### Option 1 - Windows installer (recommended)




- Download the installer:
[
** Download SimplyPrintSolidWorks-installer.exe
](https://cdn.simplyprint.io/i/static/integrations/solidworks/SimplyPrintSolidWorks-installer.exe)

- Right-click the installer and choose **Run as administrator** - registering the add-in needs admin rights. If Windows SmartScreen warns about an unknown publisher, click **More info → Run anyway**.

- Click through the installer - it copies the add-in and registers it with SolidWorks for you.

- Open SolidWorks (or restart it if it was already running), then go to **Tools → Add-Ins**, tick **SimplyPrint**, and tick **Start Up** so it loads automatically next time.


##### Option 2 - Manual install




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

- Extract the zip to a folder you'll keep around (for example C:\Program Files\SimplyPrint\SolidWorks - don't leave it in **Downloads** where it might get cleaned up).

- Open an administrator command prompt and register the add-in with RegAsm:
%WINDIR%\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe /codebase "C:\path\to\SimplyPrintSolidWorks.dll"

- Open SolidWorks, go to **Tools → Add-Ins**, tick **SimplyPrint**, and tick **Start Up**.




#### Getting started

Open the **SimplyPrint** tab in the Task Pane (or use **Tools → SimplyPrint**) to open the panel.
Click **Log in** the first time - a browser tab opens, you approve the request, and you're set for future sessions.
Pick the format, configuration, scope and mesh quality you want, then hit **Send to SimplyPrint**.
Your browser opens SimplyPrint with the model uploaded, ready to slice, queue, or print on one or more printers.

## Key features

- Export STL or 3MF directly from SolidWorks to SimplyPrint (3MF needs SolidWorks 2019 or newer)

- Engineering-grade mesh control - Coarse / Fine presets, or a Custom chord deviation (mm) and angle tolerance (degrees)
- Assemblies keep their real position, and units auto-convert to millimeters
