6 Best Online Slicers to Try — 3D Slice on the Cloud
Slice 3D models on the web
Downloadable 3D slicers offer the advantage of running locally without an internet connection, ensuring you can work even when there is no connection. However, they have limitations, especially when it comes to hardware requirements. For example, some require more computing resources, which might not be compatible with older or less powerful devices.
Additionally, they can be inconvenient for those who work in collaborative settings or those who want the flexibility of slicing their files using multiple devices without installing the software on each device. This is where online 3D slicers step in as the best alternative. They eliminate hardware constraints and allow you to slice your files anywhere with an internet connection. There are many available, but we shall describe six common ones. They come with pre-configured profiles for the majority of the best 3D printers. Without further ado, let’s have a look at them.
1. REALvisionOnline

3. Choose your experience level then you will see an option to sign up using your Google account.
4. Select one of the plans. That is, a free trial or the unlimited version that costs only $4.95/m.
5. Import your 3D model to the platform by dragging and dropping it into the workspace, or double-click it. There is also an option to add more files by clicking on Add more files section.
6. Position the object by clicking and dragging.
7. Rotate by double-clicking to resize or rotate. You will see a new interface launching with options to select the width, height, and depth sizes on the right.
Once you apply your settings and you are ready for 3D printing, click Print found at the bottom right section. Once the slicing process is complete, click Click to download to get your G-code to send to your 3D printer.
In addition to slicing ability, REALvisionOnline also includes a built-in repair tool that is useful in fixing any issues with your design without having to install any other software. It also comes with many learning resources, like the maker academy, which makes it easier to master how to use the slicer with ease.
2. SelfCAD
SelfCAD
SelfCAD is 3D design software that comes with its own online slicer, so you don’t need to switch between different programs to design or slice your files. The software has a free version, which is limited in functionality, and the paid version costs $14.99/m, but the slicer is entirely free. SelfCAD slicer is also compatible with most of the common FDM 3D printers and if you don’t find your 3D printer, you can request and they will add it.
You can import files to SelfCAD in most 3D file formats. After importing to SelfCAD, you can use the Magix fix tool to check if it has any errors and fix them before you slice to ensure that it’s ready for 3D printing. Follow the steps below to learn how to use the software.
1. Visit SelfCAD website then create an account or login if you have already registered. Start a new project, then launch the editor.
2. Import your 3D model by going to File > Import. You can also use the various tools of the software to design your file from scratch instead of importing it.
3. Select the object, then choose Magic Fix from the Tools section and use it to check if your design has any errors.
You can also check if there are nonmanifold edges by using the Flip normals tool found in the Utilities section before using the Magic fix tool to fix. If the file has any manifold issues, you will see a notification and you can go ahead and fix it. If there is none, you can proceed to slice.
4. Click 3D print tool to access the slicer.
5. Select your 3D printer from the tab that launches, and you will see the slicer interface.
When you click the object, you will see an option to rotate, resize, and even change the orientation of your 3D print.
6. Choose the material, infill, and even supports settings from the top menu. You can access additional settings from the Settings section. One of the key settings of SelfCAD slicer is the Mesh Fixes option which, just like the Magix fix helps to rectify any errors in your mesh, like fixing overlapping and disconnected faces and removing holes and empty layers.
7. Click Slice when you have applied the settings, and you can preview your design and see how it will be 3D printed.
You will also get to know the size of the filament you will need as well as the time it will take to 3D print. Download the G-code by clicking on Save the G code.
3. AstroPrint
AstroPrint
AstroPrint was specifically designed to simplify the 3D printing workflow by offering an interface for users to manage multiple 3D printers and monitor 3D prints from anywhere. It supports various 3D printers and you can slice your files using a variety of 3D slicers like Cura and this gives you the flexibility to use the tools that you are already familiar with but now on the cloud and no need for powerful local hardware. You can customize print settings and fine-tune settings like layer height, infill patterns, and supports. Follow the steps below to learn how to use AstroPrint.
1. Visit AstroPrint website and sign up.
2. Select your 3D printer by going to Printer Profile then select the 3D printer from the drop-down menu.
3. Import your 3D model by clicking on External STL Uploader. You can also get 3D models from AstroPrint or Thingiverse's design library. There is also an option to open 3D slash software and start creating your file before importing it into the software. To get 3D models directly from Thingiverse, you have to authorize it and when you have done so, you will be able to browse Thingiverse library directly on AstroPrint.
After importing your file, you will see an option to view your file in 360 degrees and also an option to edit it.
4. Edit the file by clicking on the Edit option.
You can move, scale, rotate, and even cut the object. There is also an option to change the orientation and properly position your file.
5. Click Print when you finish editing and you will see an option to save your file before being redirected to the page where you will choose the material profile, and you will also see other advanced slicing settings.
6. Click Slice to slice the file, or you can print directly from AstroPrint if your 3D printer is connected to the platform by clicking Print.
