What is Printnanny?
PrintNanny is an AI-powered assistant designed for managing and monitoring 3D printers, particularly suited for 3D print farm operators, hobbyists, and small businesses. It uses computer vision and machine learning to provide automated quality control, detecting print failures like spaghetti extrusions, layer warping, and collapsed structures in real-time. When issues are detected, PrintNanny can automatically pause the print job or send alerts to users, preventing material and time wastage.
Key features include real-time monitoring with camera streaming that works without an internet connection, PrintNanny OS (an operating system for Raspberry Pi that integrates OctoPrint, Klipper, Moonraker, Mainsail, Tailscale, and Syncthing), Gcode macro synchronization, over-the-air web-based software updates, remote access via cloud functionality, and a user-friendly web interface for comprehensive job overview. The tool offers settings and macro editor allowing users to tweak configurations without SSH terminal access, and provides custom packages for enterprise customers to distribute software packages and Gcode macros.
PrintNanny is ideal for 3D printing enthusiasts who want early error detection, small businesses using 3D printers for prototyping requiring consistent output quality, makers and hobbyists using OctoPrint or Raspberry Pi, and print farm operators needing to manage multiple printers remotely. Its mission is to automate the annoying and tedious parts of 3D printing so users can focus on growing their 3D printing business.

Frequently asked questions about Printnanny
What is PrintNanny?
PrintNanny is an AI-powered assistant for 3D printers that automates monitoring and quality control. It uses computer vision and machine learning to detect print failures like spaghetti extrusions, layer warping, and collapsed structures in real-time. When problems are detected, it can automatically pause prints or alert users, preventing material waste. It includes PrintNanny OS for Raspberry Pi and integrates with OctoPrint, Klipper, and other 3D printing tools.
What hardware do I need to use PrintNanny?
You need a Raspberry Pi 4 with at least 2GB of RAM (4GB is recommended for best performance). A Raspberry Pi 3B will not work. You also need a power supply, camera, heatsinks, and a Micro SD card rated for 10 MB/s data transfer. PrintNanny is currently working on a hardware kit that will include a Raspberry Pi 4 for US/Canada shipping.
Does PrintNanny work with any 3D printer?
PrintNanny works with most printers that can connect to OctoPrint, making it compatible with a wide range of FDM printers. It integrates seamlessly with OctoPrint's plugin ecosystem and also supports Klipper firmware through Moonraker and Mainsail.
How does PrintNanny detect print failures?
PrintNanny uses computer vision and machine learning (Google's TensorFlow) to analyze each layer of your print in real-time. The system examines repeated images of the print job and makes decisions about whether the print is ok or has failed. It can detect surface blistering, layer warping, temperature effects, geometric imperfections, and catastrophic events. When a failure is detected above the confidence threshold, it can alert users or automatically pause the print.
Does PrintNanny require an internet connection?
No, PrintNanny's monitoring and camera system is designed with privacy and reliability in mind and works without an internet connection. All data processing for failure detection is done locally on the Raspberry Pi. However, cloud functionality and remote access features do require internet connectivity.
Is there a free plan or free trial?
PrintNanny offers a Free Plan that includes 1 active printer, AI print monitoring, basic failure detection, OctoPrint integration, and email alerts - perfect for casual users. However, there is no free trial for the Founding Member program during closed beta; you can only access PrintNanny after your membership is processed. But they offer a full refund policy if you're not satisfied.
What is PrintNanny OS?
PrintNanny OS is an operating system for Raspberry Pi that lets you mix and match your favorite 3D printer tools. It includes web-based software updates (no need to re-image SD cards), and bundles tools like OctoPrint, Moonraker, Mainsail, Klipper firmware, Tailscale for secure remote access, and Syncthing for file syncing. It serves as the operating system for your 3D printing equipment.
What alert options does PrintNanny provide?
PrintNanny sends alerts when quality standards are not met, promoting proactive issue resolution. Alert options include email alerts on the Free Plan, and Slack/Discord alerts on the Pro Plan ($7/month). Users can be notified or prints can be automatically paused if a print job doesn't pass quality control.
Can I use PrintNanny for a print farm?
Yes, PrintNanny is specifically designed for print farm operators. The Farm Plan at $14/month includes unlimited printers, extended print history, live metric dashboards, export analytics reports, API access, and priority support. Features like queue management to automatically re-route failed jobs to alternate printers and the ability to control multiple printers through a web interface make it ideal for print farms.
What is the refund policy?
PrintNanny offers a full refund policy. If you're not satisfied with PrintNanny or realize the Founding Member program isn't a good fit, you can send an email to [email protected] to start the refund process. This applies to Founding Memberships during the closed beta period.
