【3D Printing】Prusa EasyPrint: Slicing on Your Mobile Device!
Josef Průša:Ever since I built my first 3D printer, I've been dedicated to making 3D printing more accessible.
Part of that was dreaming of a slicer that could run on any device, smoothly, and be usable by anyone.
We've finally made it a reality! After countless hours of development and testing, I'm proud to introduce Prusa EasyPrint!
It's a game-changer: slicing on phones and tablets has never been this easy.
Eliminating Slicing Barriers – What is EasyPrint?
While many of us are perfectly accustomed to dragging and dropping models into PrusaSlicer and selecting a preset profile, for a complete beginner, it's not as easy as it sounds.
Just needing to install a new application can be a bit of a hurdle.
Then, you also have to import the correct profile for your printer.
You have to know where to click to select the correct material, and so on.
With EasyPrint, all of this is streamlined and incredibly simple.
It's the easiest and most seamless slicing experience you've ever had.
You are browsing Printables on your phone, computer, or tablet.
Find a model you like, and with a single click, you jump straight into a 3D preview.
It automatically detects your printer in PrusaConnect, applies the correct profiles, and all you have to do is hit "Print."
It's packed with convenient and intuitive features. If you want, you can quickly move, rotate, or scale models, use the surface placement feature, auto-arrange multiple models on one or more virtual print beds, and more.
We even implemented a simple "shopping cart" for Printables, so you can add more models to this cart while browsing Printables, and then print them all at once.
You can also change basic settings – print quality, infill, supports, and so on.
And that's it, anything more complex is intentionally kept behind the scenes and configured automatically.
Remember when we launched Printables and emphasized the ability to share G-codes?
The goal is the same: making 3D printing more accessible.
Who is EasyPrint for?
Beginners: If you're new to 3D printing, slicing can feel overwhelming, but EasyPrint removes that barrier.
No complex settings, no profile setup – just click, slice, and print.
Anyone can do it, no experience required. No guides and tutorials needed.
Chromebook Users (Schools): No need to install specialized software or overcome system limitations.
Students and teachers can simply open a tab, prepare their 3D models, and send them to print.
Or download the G-code to a USB stick.
Power Users with Tablets: Modeling on Shapr3D on your iPad?
You don't need to transfer files to your computer for slicing.
Your Non-3D Printing Relatives and Friends: Tired of being the "3D printing specialist" for your loved ones?
Now, your partner, kids, siblings, or parents can handle their own projects.
Slicing on the Go: If you're already familiar with slicers, Prusa EasyPrint is still incredibly convenient.
You can start a print from your phone while relaxing on the couch – perfect when you know you'll use default settings anyway.

How Does it Work?
We're sure this will be copied very soon, so there's no reason to keep how it works a secret.
Prusa EasyPrint is a clean, responsive web application that lets you move 3D models and set some basic settings.
It's tightly integrated with our services like Printables and the mobile Prusa Connect app, so it knows which printers you own, what materials are loaded, and if your printer is ready.
It can easily import models from Printables or import models from local storage.
Once you hit print, it sends the entire scene to PrusaSlicer running on powerful servers, which generates the G-code and sends it to your printer.
If you're reading this, you might be thinking: Oh no – here's another way to lock users into a cloud platform.
I really hope you consider this, as it's an important issue today.
Let me explain why that's not the case here.
First of all, Prusa EasyPrint is completely optional.
You can continue using PrusaSlicer locally on your computer and never touch Prusa EasyPrint at all, if you wish.
In fact, Prusa EasyPrint isn't really a slicer – it's a web frontend that generates 3MF files compatible with most modern slicers.
The interface runs on your device, while the actual slicing happens in the cloud on our servers.
We use the same version of PrusaSlicer that's publicly released; you can find its source code on GitHub.
The web frontend is not open source (similar to Printables or PrusaConnect), but, since the frontend relies on PrusaSlicer and its performance and features, we are more motivated than ever to continue improving our standalone application.
In fact, one of my favorite features is how seamlessly the two work together.
You can always click a button to download your project and open it in PrusaSlicer on your computer.
Everything (models, orientation, settings) is saved as a 3MF file.
From there, you can fine-tune it with advanced tools like paint-on supports or custom modifiers.
Then, you can simply export the G-code file, put it on a USB drive, or send it to the printer over the local network.
On top of that, there's no other way to enable slicing functionality on, for example, a $200 Android tablet and phone. Believe me, we tried.
Basic requirements like RAM limits on such devices are so stringent that all our attempts failed, so at least for the foreseeable future, this is the only way to offer this functionality.
I also hope our track record speaks for itself.
Security is one of our main selling points, and our printers are used in top companies, universities, and research institutions worldwide.
The application is designed to run all PrusaSlicer-derived slicers (Orca, BambuStudio, and many others) alternately on the backend.
So I'll let slip a little secret that we plan to open this functionality to non-Prusa 3D printer users in the future.
Of course, the timing is not yet certain, as we need to gather all information from testing, and we need to ensure everything is stable after accommodating all Prusa users.
3D printing should be open to everyone. We don't want to build any walled gardens.
In fact, quite the opposite – we want 3D printing to be easier for everyone.
Using with Offline Printers
We've added an "Add Offline Printer" button, allowing you to select printers not connected to the internet.
So, you can use cloud slicing and the easy user interface to slice models for printers that operate offline.
Finally, you simply download the G-code and transfer it to your printer via USB/SD card.
