AstroPrint

AstroPrint is a platform for managing 3D printers and printer fleets, with tools for preparing files, monitoring jobs, and reviewing printer activity. Its cloud library stores STL and G-code files, and designs can be sliced in a browser. A cloud dashboard can also generate printable 3D models from text prompts. From a computer or smartphone, users can check prints and pause, resume, or cancel them remotely. Analytics show filament use, printer operating hours, and print success rates. Printers can connect through AstroBox Touch, AstroBox Gateway, a self-built AstroBox, or the OctoPrint plugin; the mobile app can find Thingiverse designs and start prints. AstroPrint is available on Android, iOS, Linux, macOS, Windows, web, API, and self-hosted platforms. The free Basic plan includes two printers, one user, and 1GB of storage. Premium costs $9.90/mo and includes five printers, with additional printers at $5 each. Klipper support is limited to slicing, and live video streaming in the mobile app requires using a browser.

AstroPrint combines file preparation, remote printer controls, and fleet analytics across a broad set of platforms. The free tier has defined user, printer, and storage limits, while larger organizations can request Business & Education pricing.

AstroPrint suits makers and education settings managing printers, as well as casual users looking for a free tier. Teams needing fleet management can consider its paid plans, though Business & Education pricing is by quote.

AstroPrint is a cloud platform for preparing prints and managing 3D printers, aimed especially at makers and education users. It is strongest when file handling, remote controls, and fleet oversight belong in one workflow; per-printer and storage charges can make expansion costly.

Overview

AstroPrint combines a cloud library for STL and G-code files with browser-based slicing, remote printer controls, and print analytics. Users can monitor jobs and pause, resume, or cancel them from a computer or smartphone. Analytics track filament use, printer operating hours, and print success rates, making the service useful for reviewing activity across more than a single job.

Printers connect through AstroBox Touch, AstroBox Gateway, a self-built AstroBox, or the OctoPrint plugin. The cloud dashboard also includes an AI tool that generates printable 3D models from text prompts. That range makes AstroPrint a management platform, not just a way to prepare files; users who only need a slicer may have little reason to pay for its fleet features.

Key features

Cloud preparation and discovery

Keeping STL and G-code files in a cloud library and slicing in a browser puts preparation and printer management in the same service. The mobile app can search Thingiverse designs and start printing them, which helps users move from finding a design to sending a job without leaving the app. The dashboard's text-prompt model generation adds a separate way to create printable models.

Remote monitoring and fleet insight

Remote pause, resume, and cancel controls are practical when a printer needs attention away from its workstation. Filament, operating-hour, and success-rate analytics provide useful operating measures for a fleet, though they do not replace direct oversight: live video streaming is not available in the mobile app, and AstroPrint directs users to a browser for live streaming.

Printer connections and limits

AstroPrint supports several connection routes, including the OctoPrint plugin, giving users different ways to bring printers into the service. Klipper is supported for slicing only, so Klipper users should not assume AstroPrint provides the same management support for those printers.

Pricing

AstroPrint uses a freemium model. Basic is free and includes 2 printers, 1 user, and 1GB of file storage. That is a sensible fit for a casual user or a small setup, but the one-user cap rules it out for a shared classroom or team unless they move to a paid plan.

Premium costs $9.90/mo and includes the first 5 printers, 1 user, and 10Gb of file storage. Each additional printer costs $5/printer after, and each additional 10GB costs $1/addt'l 10GB. The larger storage allowance and expanded printer capacity suit an individual maker with multiple machines, but a single seat remains a meaningful constraint for collaborative use. The recurring per-printer and storage charges also matter as a setup grows.

Business & Education has custom pricing, with unlimited printers, users, and file storage. It is the tier built for larger organizations that need broad shared access; priority single point-of-contact phone support is included. Premium includes priority email support. AstroPrint's enterprise page advises contacting the company about using networked 3D printers securely; it does not specify a certification there.

Platforms

AstroPrint is available on Android, iOS, Linux, macOS, self-hosted setups, the web, and Windows, and it offers an API. AstroPrint Desktop is compatible with Mac OS X, Windows, and Linux. Mobile users should note the lack of in-app live video streaming and use a browser for that view.

Who it's for

AstroPrint fits makers who want cloud file storage, browser slicing, and remote control together, and education or business users who need to manage a larger printer fleet. The free plan suits casual use within its two-printer, single-user, and 1GB limits. It is a weaker choice for teams that need multiple users without moving to custom pricing, or for Klipper users seeking printer management rather than slicing alone.

Pros and cons

• Pros: Cloud files, browser slicing, remote controls, and fleet analytics share one platform, reducing the need to split those tasks across separate tools.
• Pros: Multiple printer connection methods, including an OctoPrint plugin, offer several routes into the service.
• Pros: Business & Education removes printer, user, and storage caps, with priority phone support for organizations.
• Cons: Basic is capped at one user and 2 printers, limiting its usefulness for shared or growing setups.
• Cons: Premium remains single-user and adds charges for printers beyond five and storage beyond 10GB.
• Cons: Klipper support is limited to slicing, and mobile users must switch to a browser for live video.

Alternatives

3D Printing Software is a broader category for comparing tools beyond AstroPrint.

• Polar Cloud is another freemium option. Its free plan covers 1 printer, 5 print jobs per month, 7-day history, and 300 MB of storage, and accepts mesh files only with a 30 MB file limit. Choose it when those tighter quotas suit a small trial setup and you prefer its $9.00 per-month paid tier to AstroPrint's $9.90/mo Premium.
• SimplyPrint is freemium with a free plan for up to 2 printers, 1 user, and 1 location, plus 15 cloud slices and 12 AI Failure Detection hours per month. Consider it when those specific monthly allowances match your workflow.
• Obico offers a free plan for 1 printer, 10 AI Detection Hours per month, and basic streaming up to 5 FPS, throttled for 30 seconds per minute, with OctoPrint tunneling limited to 300. It is an alternative for users whose needs fit those free-plan limits.
• PrusaSlicer is free, open-source slicing software based on the Slic3r project. Choose it when the priority is an open-source slicer rather than AstroPrint's cloud library and fleet management.
• 3DPrinterOS has a paid Premium plan at $19.00 per month for 2 printers and 1 user, plus an Education plan with custom pricing and an extended trial available. It may suit readers considering a paid alternative with an education tier.
• RaiseCloud is a free option.
• OctoPrint is a free alternative.
• Bambu Studio is free slicing software with an optional networking plugin and SD card printing without the plugin. Choose it when file preparation and SD card printing are enough without AstroPrint's broader fleet-management workflow.

Verdict

AstroPrint is a strong fit for makers and education users who want cloud file handling, browser slicing, remote controls, and fleet analytics together. Its free tier is a practical starting point for one user with a small printer setup, while larger organizations gain uncapped capacity and priority phone support on Business & Education. Look elsewhere if a shared team must stay on a low-cost plan, if Klipper management is essential, or if mobile live video is a requirement.
