When you think of 3D printing, the word “strong” probably doesn’t come to mind.
I mean, most 3D printed models are pretty weak and brittle. But what if I told you there’s a filament material so strong that a simple hook printed in the filament can hold over 650 pounds without breaking?
That filament’s name is polycarbonate, or PC for short, and it’s the strongest filament material for consumer-grade 3D printers known to man. It’s literally used in bulletproof glass. So if the President of the United States trusts the strength of polycarbonate, then so can you!
Polycarbonate is an excellent filament choice if you want to 3D print real-use parts that will face a lot of physical stress, like a door hinge or an RC car frame.
However, with great strength comes many struggles, and PC filament is notoriously difficult to print with very intensive hardware requirements.
If you want a printer to use for PC filament, I’d suggest getting the Prusa i3 MK3S+ and building (or buying) your own enclosure. However, if you’ve got a smaller budget, the Creality CR-10S is a great bang for your buck, though you still will have to get your own enclosure for the machine.

Overall, the Pulse XE is an incredible printer, able to print just about anything. It’s a good printer for general use but is amazing for printing filaments beyond the norm. The Pulse XE makes sure those sorts of filaments are printed successfully.
This printer is recommended for anyone wanting to print beyond the limits of PLA and ABS filaments (perfect for PC printing!!).
What is a Polycarbonate?
Polycarbonate is a thermoplastic material originally derived from processed propane and other materials. Plastic is commonly used for medical devices, eyewear, and so much more. It’s also pretty popular for 3D printing!
In fact, polycarbonate filament is considered the single strongest filament material, achieving tensile strengths greater than ABS, PETG, and even Nylon. When tested, a clip 3D printed in polycarbonate was able to hold an incredible 685 pounds without breaking, while PLA and ABS both failed before 300 pounds. So next time you’re printing a gear or another model that will face physical stresses, definitely give PC filament a consideration.
But strength isn’t the only unique property of polycarbonate!
For instance, PC is a hygroscopic material. This means the plastic absorbs moisture from the air pretty rapidly. So, if you leave a spool of PC filament in a humid environment, it will soak it all in, leading to bubbling in the hot end and brittle prints. As such, it’s recommended to always store PC filament in a drybox or sealed container of some kind.
Similar to PLA, PC is also decently sensitive to UV light so it should only be used for indoor projects.
Polycarbonate filament comes in a multitude of colors but is usually transparent as this is the natural color of the plastic. This makes PC a unique choice as it is one of a few filaments that you can use for printing transparent items like lamp shades.
Sadly, though, printing polycarbonate is no easy feat.
We’ll talk more about how you can print PC in a later section, but it requires much more intensive hardware requirements than almost any other traditional filament material. And, even with the necessary hardware, you’ll have to fine-tune a slicer profile in order to achieve high-quality prints.
When To Use Polycarbonate?
Polycarbonate is perfect when you are in need of a strong or transparent material. That’s why PC is so popular for industrial applications that require a lot of strength, such as machinery guards, eyeglasses, and even bulletproof glass.
Similarly, in a 3D printing setting, you should use PC filament whenever you want a model to be super strong and durable. For example, if you’re printing a computer monitor stand, door hinge, or a gear for a robot, you’ll want all the strength you can get, and PC provides just that!
Sadly, though, you shouldn’t use PC for outdoor prints as the plastic won’t respond well to the UV light from the sun. So if you need a strong outdoor print, consider using PETG filament.
Also, you shouldn’t use polycarbonate filament when you want to print a display model, like a miniature or cosplay set. While you may want these models to be strong, PC isn’t the best at providing detail in 3D prints, so you should consider materials like PLA or ABS instead.
Advantages and Disadvantages of Polycarbonate 3D Printing
As mentioned above, there are numerous advantages when it comes to printing with PC. In addition to the material’s strength, heat resistance, and natural transparency, PC is also more durable, flexible, and less dense than other filaments.
Transparency comes with its own advantages! The transparent nature of PC is helpful in printing and also serves as an aesthetic option.
However, there are some things to look out for and consider such as printing machinery, print settings, and the surrounding environment before using PC.
When printing with PC, there are several extensive hardware requirements. PC requires the use of a hot nozzle, heated bed, and an enclosed printing space. These requirements are necessary as PC is very sensitive to its surroundings and will not print properly unless all parts are correctly set.
Printing issues such as warping of the finished product and over-extrusion can arise if printing and storage requirements are not met. As mentioned earlier, PC is hygroscopic and will react negatively (usually swelling) when introduced to water directly or if there’s any water in the air. It is critical to keep your PC filaments and projects in dry areas.
PC’s last disadvantage is its price. While it is a little steeper than other filaments, it is worth it in the long run for certain projects due to the strength and heat resistance PC has. Prices vary between brands and based on quality but they usually sit between $30 and $60 for a spool around 750 grams.
How to 3D Print Polycarbonate?
Printing with PC can be difficult if you don’t have the proper setup or settings met. However, once you have perfected the necessary requirements, the payoff is worth it.
Your first step when printing with PC is to make sure the material is dry. The hygroscopic PC will warp if it was exposed to too much water before printing, so before you even touch your printer settings, make sure your filament was stored properly in a dry environment.
Next, you need to look at the temperature of your nozzle. PC is extremely heat resistant, which is great for the final project but makes the printing process a little difficult. You want your nozzle temperature to sit between 300-310 °C to make sure the PC will flow properly, but of course, play around with your own setup to see what works best for you.
After setting your nozzle temperature, it is time to adjust the bed temperature. Considering that the PC is already coming out extremely hot, it’s important that you make sure that the filament does not stick to the bed!! To do so, the ideal bed temperature ranges from 145-150 °C, but a consistent heat of 135°C is also acceptable if it is the most your printer can do.
It is also important to have an enclosed printer to ensure that the ambient temperature around your printed model is high enough to ensure good layer-to-layer adhesion during the printing process.
There are some extra things to take care of before you start printing. Make sure to disable any cooling fans during the printing process as it can cause the filament to warp and have other negative responses. Also, just like other filaments, the first layer is the most important!! If your print settings are not met perfectly, the rest of your print can suffer. But PC is easily recyclable so don’t worry if your first layer isn’t ideal.
Factors to Consider When Choosing a 3D Printer for Polycarbonate:
If you’re still here, you’re probably interested in purchasing your own 3D printer. But don’t just buy any 3D printer because most aren’t equipped with the hardware necessary to print polycarbonate filament. In the mini-sections below, we’ve gone over the main features to look for on a 3D printer for printing PC, such as bed temperature, enclosure presence, and more!
The first and most important factor to look at in a 3D printer is its material compatibility. Usually, the manufacturer will list which filaments do and don’t work on the machine but don’t always trust this information. Instead, look in the reviews and on Reddit (or other forums) to see which filaments actual users were able to print on the machine.
Also, make sure to check the maximum nozzle temperature, as this is a big regulator for material compatibility. If the nozzle can’t reach and stay at the necessary temperatures for printing PC, then the printer can not actually print polycarbonate. Remember: you want a maximum nozzle temperature of between 260-310 °C if you want to print PC.
It’s crucial to check the printer’s maximum bed temperature and to have a properly heated bed. PC will stick to a bed that’s not properly heated, which can cause damage to your print and can even make it impossible to remove the print from the bed. The max bed temperature in most printers sits at 135°C. However, the optimal temperature for printing PC sits between 145°C and 150°C. Looking for or modifying a printer that can reach those bed temperatures can make or break a project.
As we mentioned, an enclosure is also necessary for printing PC filament, as it keeps heat around your model and prevents air draft. Without one, your PC prints will be super brittle, contain low-quality detail, and have other issues.
As such, you should look for a 3D printer that has a built-in enclosure. However, you can also get a printer without one and then build or buy an enclosure for the printer afterward. This is what I like to do as it usually ends up being cheaper (especially if you DIY it), and gives you some customization abilities. Check out our article on the best enclosures here.
The bed’s material is just as important as its temperature. A Polyetherimide (PEI) sheet is the best printing bed option for PC. Painters tape or glue sticks will adhere permanently to the prints due to its high printing temperatures, so they are not viable options, but PEI is extremely heat resistant and has high-temperature stability– great for PC printing!!
Lastly, don’t forget about the build volume. You wouldn’t want to get a printer that’s perfect at everything but can only print super tiny models.
While there’s no single volume that’s good for everyone, it’s smart to think about the sizes of the models you’ll be printing and establish a minimum volume that you’re looking for. For example, when I look for a 3D printer, I don’t choose one unless it’s got at least 200 x 200 x 200 mm of print space.
Are you ready to start printing with PC now? While printing with polycarbonate may be intimidating due to the filament’s requirement for a perfect climate, don’t worry! This is an opportunity to use this incredible material.
PC is extremely strong, durable, heat resistant, and unique to use. The main takeaway about printing with polycarbonate is the printing environment. Make sure to store your PC in a dry environment, or it will swell and can ruin your print. Also, make sure your printer has the proper nozzle and bed temperature and is a properly enclosed space to create the best environment for the PC.
Our recommendations from this selection of printers would vary based on what you want. If you’re looking for an enclosure for quality, the Prusa i3 MK3S+ is the best option for you. The CR-10S is perfect if you want an enclosure for build space and the Pulse XE is the go-to for any other feature you want, like automatic bed leveling.
The feats of 3D printing are never-ending and, while a more difficult process, printing with polycarbonate only further proves that anything can be possible.
