My Antivirus Software is Showing Warnings
GrabCAD Print has several background processes, any of which might be flagged as malicious by your antivirus software simply because they run in the background. Getting past these messages generally means hitting "Allow" whenever they appear, and preventing means adding GrabCAD Print to the list of approved programs. This process will vary depending on your antivirus.

Problems Downloading, Installing, Starting Up, Logging In, or Updating
Downloading
The application is available for download at http://grabcad.com/print and will download an .EXE package installer file when you click "Download GrabCAD Print."
If nothing happens after clicking the button, your browser security settings or third-party firewall may be preventing you from downloading .EXE files. Please check those configurations in order to proceed with the download.
Installing
Once the installer is downloaded, double click the .EXE installer file to start the installation. If the installation fails after a short while, you may not have permissions to install programs on your PC.
Right click on the installer and select "Run as administrator" or contact your IT department for assistance.
Please also verify that Windows is updated to the latest version: if not, type "Windows update" on your search bar, and verify the updates status accordingly.
Starting Up
Double clicking the shortcut or launching "GrabCAD Print" from the Start menu should launch the app. If the app does not launch, your antivirus may be blocking the program, however it should appear with a message in this case. If absolutely nothing happens after repeated tries to launch the program, try reinstalling, then contact your IT department or your 3D printer service provider for assistance.
Logging In
In order to log in to GrabCAD Print, you will need a GrabCAD account with access to a company account. Click here to read in detail about signing up.
Be sure to check your internet connection. If your PC is not connected to the internet, you will not be able to log in to GrabCAD Print.
If you're sure you have everything you need and you still cannot get through the login screen, your firewall may be blocking access to print-api.grabcad.com. Check with your IT department to allow this connection.
Updating
When a new version of GrabCAD Print is released, the download will begin automatically if/when the application is open. Then, once it's completed the download, the next time the application opens it will install the updates.
You can use the "Check for updates" option in the Help menu to monitor this process. If an update is available, it will tell you that the download is either in progress or completed. Once it's completed, restart the application to install the updates.
Updates come from api.grabcad.com, so if you are having firewall issues, check with your IT department to add this address to the list of exception.
If this process fails for any reason you can get the latest installer here. First uninstall via Windows Control Panel and then install the new version.
Trouble Connecting to My Network Printers
PolyJet printers require a few extra steps to connect. See this guide for more details: Setting up your PolyJet printers for GrabCAD Print.
If you've already gotten your J750 or Objet1000 Plus connected and are having connection issues, try uninstalling and reinstalling the GrabCAD PolyJet Job Manager.
It's good to check that the connection between your computer and the printer is working outside of GrabCAD Print. You can do this from the command terminal. Click the Start button and type cmd to bring up the Command Prompt program. Once open, type ping and then your printer's IP address, and then hit Enter. For instance, if your printer's IP is 10.10.14.129 then you would type ping 10.10.14.129 into the terminal. If the connection fails, and you are sure that you have typed the IP address correctly, then ask your IT department for assistance in restoring the connection.
Network discovery needs to be on. If your PC is brand new or you just reinstalled Windows, it may be off. Go to Control Panel > Network And Sharing Center > Advanced sharing settings to enable it.
Your antivirus may interfere with GrabCAD Print making any kind of connection with networked devices. Make sure your antivirus is not blocking any of the programs listed above.
Your printers may not be discoverable on the network by default. You can first try adding it via IP if UPnP is blocked on the network. To turn on Printer Discovery, go to your printer. In the GUI of the printer, navigate to the settings and enable UPnP. Your printer should now be discoverable on the network if you are on the same subnet. Learn more about connecting to your printers directly or by IP.
Computers with 2 network cards may not be able to see printers from both networks.
When you connect your computer to a network, you can decide if this network is a Home, Work, or Public network. If you selected public, then printers on your network will not be accessible from your PC.
During installation, GrabCAD Print will set up the proper network permissions to access your local network. However, if you changed your network type, these permissions may no longer apply. Click here to figure out how to change your network type in Windows 10, Windows 8/8.1, or Windows 7.
Printers that are undiscoverable (turned off or moved to another network) for 14 days will be removed from your printer list.
Unexpected Error Messages or Behavior
Although we are constantly improving our error handling, some situations may cause an error message that is unhelpful. Here are a few common cases:
Completely Blank Viewer Area and Errors when Adding Models
If you see a message saying "An internal error occurred" when trying to add a model, and you see an blank white space in the middle of the application instead of a grey empty tray, then the viewer process has stopped working. If this happens on your first time launching, it is likely that your computer does not support WebGL because your graphics card drivers are out of date. Update your graphics card drivers and restart GrabCAD Print.
PolyJet Printer Has "Error" State in GrabCAD Print but "Idle" on the Embedded Software
If your printer is loaded with a combination of materials that are incompatible, jobs cannot be sent. Unfortunately there isn't an informative error message to let you know which materials are causing the conflict, but a common problem is having one of the Digital ABS material and not the other, or a mix of Veroflex and Vero materials.
Unable to Connect to a PolyJet Printer or Template
If you see a message saying "PJ service firmware is out of date" whenever you try to connect to a PolyJet printer or template, then something has gone wrong with the background service for PolyJet components. It's possible that your computer does not meet the system requirements, especially those around AVX support. Run this tool from Intel to ensure "AVX Support" is supported on your computer.
Graphics Are Running Slowly
Large models can generate very large quantities of data, and this can lead to the graphics in GrabCAD Print appearing to be slow and unresponsive. In extreme cases this can even lead to errors being reported by the application, such as "WebGL Context lost."
Apart from large models there are two other potential reasons why GrabCAD Print graphics may be slow:
- Your laptop is running on battery power
- Your computer does not have a dedicated graphics card, and instead uses the main CPU, known as "integrated graphics"
Our system requirements recommend a dedicated graphics card with 8GB of video memory for optimum performance.
If You only Have an Integrated Graphics Card
You can configure your graphics setting in GrabCAD Print's System Preferences. Based on available hardware we will choose a default setting, but you can change this at any time.
Low (faster) | Medium | High (slower) | |
---|---|---|---|
Toolpaths in Slice Preview * | 2D only | 3D with LoD | 3D |
Antialiasing | Off | On | On |
Shadows | Off | Stencil shadows | Soft antialiased shadows |
Display Graphics Mesh Accuracy ** | 1.0mm (0.004") | 0.1mm (0.0004") | Full resolution |
Display Graphics Mesh Detail *** | 0.5% distance tolerance | 200,000 triangles | Full resolution |
* If you cannot change your viewing mode in Slice Preview, it is because your graphics setting is set to "Low." You must change this to Medium or High in order to use 3D toolpaths.
** Mesh accuracy controls the number of triangular facets generated for the display of models. Analysis mode, Slice Preview and Accurate compose all work on the fully detailed mesh. The setting does not affect the resolution of printing in any way.
*** Mesh detail controls the triangle simplification of mesh formats (e.g. STL, VRML, OBJ, 3MF) for the display in GCP. You can switch the display between the simplified and full resolution model from the right mouse button menu. The setting does not affect the print resolution in any way.
If You Have a Dedicated Graphics Card that Meets the Requirements, but Still Have Problems
Users who have a dedicated graphics card in their computers may still experience slowness, because the computer has decided not to use it for GrabCAD Print. You can correct this by following the procedure below:
Using Windows Settings
Click the Start button and then open the Settings panel. Choose System and then Display and scroll down to click on Graphics Settings.
From here, click Browse to select GrabCAD Print. You will find GrabCADPrint.exe in the following location: C:\Program Files\Stratasys\GrabCADPrint
Once added, click Options to open the graphics preference and set it to "High Performance" and click Save.
For nVidia Graphics Cards
Right-click on the GrabCAD Print desktop shortcut and select: Run with Graphics Processor > High Performance.
You can also apply this change more permanently using the nVidia Control Panel located in the system tray on the Windows Desktop, this allows you to associate a graphics processor with a specific program:
For AMD Graphics Cards
For AMD devices, you can right-click the desktop and choose “Configure Switchable Graphics”. From there it is possible to assign the dedicated card by choosing “high performance” setting for the program.
Printing Problems
If you experience unexpected print failures, please contact your 3D printer service provider for immediate assistance.
If your PolyJet print job stopped without an error message and you cannot resume, it is likely that the Job Manager has encountered a problem. Uninstalling and reinstalling the Job Manager should resolve this issue.
- Uninstall the Job Manager
- (Optional) restart the PC
- Download the latest installer and run it
Still Having Issues?
As a last resort, the following options may help:
- Restarting: A background process (even one unrelated to GrabCAD Print) may have encountered an error without showing any signs, and restarting your computer allows these processes to resume normal functionality.
- Reinstalling: This ensures that all the necessary program files are in the proper locations. Uninstall from the Control Panel (note: this will not wipe your personal settings) then download the latest version and install. Repeat for the GrabCAD PolyJet Job Manager if you are a PolyJet user.
- Clean install: Files related to your printer list, login credentials, and preferences are left behind after you uninstall, and in rare cases, clearing them out can help resolve strange issues. Read more below:
Clean Installation Instructions
When you are encountering errors attempting to install or upgrade GrabCAD Print, often those errors are a result of remnants of old versions which are getting in the way. The best course of action is to try to get your system back to a "clean" state, removing all traces of GrabCAD Print.
- Start by going to Control Panel > Programs & Features and uninstalling all GrabCAD products.
- Download a fresh installer from print.grabcad.com and run it.
- If this fails, there is a tool from Windows that can help. Download it here: MicrosoftProgram_Install_and_Uninstall.meta.diagcab
- Run this program and choose Uninstalling and then read through the list for any of the following:
