Printing Big: How to 3D Print Large Objects with Ease

Posted by

3D printing has revolutionized the way we create and manufacture objects. It has opened up a whole new world of possibilities, allowing us to create complex shapes and structures that were previously impossible to produce. However, one of the limitations of 3D printing is the size of the objects that can be printed. Most 3D printers have a limited build volume, which means that they can only print objects that are smaller than a certain size.

But what if you want to print something larger than your 3D printer’s build volume? Is it possible to 3D print large objects? The answer is yes, it is possible, but it requires some additional steps and techniques. In this article, we will explore how to 3D print large objects, including the tools and techniques you will need to get started. We will also provide some tips and tricks to help you avoid common pitfalls and ensure that your prints come out as expected. So, whether you are a seasoned 3D printing pro or just getting started, read on to learn how to 3D print large objects.

Choosing the Right Printer

When it comes to 3D printing large objects, choosing the right printer is crucial. There are several factors to consider, including the size of the print bed, the type of filament used, and the level of detail required. In this section, we’ll cover some of the key considerations when choosing a 3D printer for large prints, as well as some recommended models.

Considerations for Large Prints

The first thing to consider when choosing a printer for large prints is the size of the print bed. Larger print beds allow for bigger prints, but they also require more space and can be more expensive. It’s important to choose a printer with a print bed that is large enough for the objects you want to create.

Another important consideration is the type of filament used. Some filaments, like PLA, are easier to work with and produce high-quality prints, but they may not be suitable for large prints due to their tendency to warp. Other filaments, like ABS, are better suited for large prints but can be more difficult to work with.

Finally, it’s important to consider the level of detail required for your prints. If you need high levels of detail, you’ll want to choose a printer with a high resolution. However, higher resolution printers can be more expensive and may require more time to print.

Recommended Printers for Large Prints

There are several printers on the market that are well-suited for large prints. Here are a few of our top recommendations:

  • Creality CR-10S: This printer has a large build volume of 300 x 300 x 400mm and is capable of printing high-quality objects with a resolution of up to 100 microns.

  • LulzBot TAZ 6: The TAZ 6 has a large build volume of 280 x 280 x 250mm and is known for its reliability and ease of use. It’s also capable of printing with a wide range of filaments.

  • Prusa i3 MK3S: This printer has a build volume of 250 x 210 x 210mm and is known for its high level of detail and precision. It’s also relatively affordable compared to other high-end printers.

Overall, when choosing a printer for large prints, it’s important to consider the size of the print bed, the type of filament used, and the level of detail required. By taking these factors into account, you can choose a printer that is well-suited for your needs and will produce high-quality prints.

Preparing Your Print

Before you start printing large objects, it’s important to prepare your print properly. Here are some tips to help you get started:

Designing for Large Prints

When designing for large prints, it’s important to keep in mind the limitations of your printer’s build volume. You may need to split your model into multiple parts that can be printed separately and then assembled later. Alternatively, you can design your model in such a way that it can be printed in sections that can be snapped together or glued.

Another important consideration when designing for large prints is the strength of your model. Larger prints are more prone to warping and cracking, so it’s important to design your model with enough support structures and infill to keep it stable.

Slicing Your Model

Once you have designed your model, the next step is to slice it into layers that your printer can understand. There are many different slicing software options available, each with its own set of features and capabilities.

When slicing your model, it’s important to pay attention to the layer height, infill density, and support structures. These settings can have a big impact on the quality and stability of your print.

Setting Up Your Printer

Before you start printing, it’s important to make sure your printer is set up properly. This includes leveling the bed, calibrating the extruder, and ensuring that your printer is clean and free of debris.

You may also need to adjust your printer settings to accommodate the size of your print. For example, you may need to increase the temperature of the heat bed or use adhesives to help your print stick to the build surface.

By taking the time to properly prepare your print, you can help ensure that your large object prints successfully and looks great.

Printing Your Large Object

Once you have designed your large object and prepared your 3D printer, it’s time to start printing. Here are some tips to help you get the best results possible.

Bed Adhesion Techniques

One of the most important factors in printing large objects is ensuring that they stick to the bed. Here are a few bed adhesion techniques that you can use:

  • Clean the bed thoroughly before printing to remove any debris or residue that could interfere with adhesion.
  • Use a bed adhesive such as glue stick, hairspray, or tape to help your print stick to the bed.
  • Level the bed carefully to ensure that the first layer is being printed at the correct height and with the correct amount of pressure.

Layer Height and Print Speed

When printing large objects, it’s important to find the right balance between layer height and print speed. Here are a few things to keep in mind:

  • Use a larger layer height to help your print finish faster, but be aware that this can result in a rougher surface finish.
  • Slow down the print speed to reduce the risk of errors, but be aware that this will increase the overall print time.
  • Experiment with different settings to find the right balance for your specific print.

Monitoring Your Print

Finally, it’s important to keep an eye on your print as it progresses. Here are a few things to watch out for:

  • Check the first few layers carefully to ensure that they are adhering properly to the bed.
  • Keep an eye on the print as it progresses to ensure that there are no errors or issues.
  • If you notice any problems, such as warping or layer separation, pause the print and address the issue before continuing.

By following these tips, you can ensure that your large object is printed successfully and with a high level of quality.


After successfully printing your large 3D object, it is important to perform post-printing tasks to ensure a smooth and polished finish. This section will cover the essential post-printing tasks for large 3D objects.

Removing Supports and Rafts

When printing large 3D objects, it is common to use supports and rafts to ensure the object’s stability during printing. After printing, these supports and rafts must be removed. A pair of pliers or a cutter can be used to remove the supports and rafts. It is important to be careful and not damage the object while removing the supports and rafts.

Finishing and Sanding

After removing the supports and rafts, the object may have rough edges or surfaces that need to be smoothed out. Sandpaper with different grits can be used to sand the object’s surface. Start with a coarse grit and gradually work your way up to a finer grit to achieve a smooth finish. A sanding sponge can also be used to reach hard-to-reach areas.

Painting and Coating

Once the object has been sanded and smoothed, it can be painted or coated to give it a more polished look. A primer can be used to prepare the surface for painting. After the primer has dried, the object can be painted with acrylic or spray paint. For a more durable finish, a clear coat can be applied after the paint has dried.

In conclusion, post-printing tasks are essential to achieve a polished and professional-looking 3D object. By removing supports and rafts, sanding the surface, and painting or coating the object, you can achieve a smooth and polished finish.
