This is Top 3D Shop, and today we are going to delve into 3D printing polycarbonate — one of the most tricky materials for the majority of users, especially beginners. Let’s find out what its properties are, how to deal with its challenges, and which 3D printers are considered the best to produce top-quality PC parts.


What is polycarbonate?

Polycarbonate or PC is a special high-performance material that is extremely durable, lightweight, transparent, and dimensionally stable. It boasts a high impact strength that greatly surpasses that of glass and acrylic materials like PMMA. At the same time, it has less than half the density of glass, with a comparably high level of transparency, which makes for a good light transmission. In addition, polycarbonate is bendable, with this flexibility allowing it to withstand high tensile forces that break or shatter filaments like ABS. The latter makes 3D printed PC parts increasingly wear-resistant. 

Polycarbonate has a high glass transition temperature of 150 °С and is also heat-resistant up to temperatures of 115 °С. Although this opens up many new applications for PC parts, it also results in a relatively high printing temperature and some other peculiarities of the printing process.

Being a hygroscopic material, polycarbonate can absorb water from the atmosphere. Since the moisture can ruin the filaments’ performance and mechanical strength, it should be kept in airtight, moisture-free environment before and during printing.

Finally, PC is rather peculiar about printing conditions and devices to work with it. For compatibility with desktop 3D printers, these filaments contain some additives that do not affect their impressive characteristics.


Why use polycarbonate in 3D printing?

Given the properties described above, there are numerous reasons why one might choose to use polycarbonate when 3D printing. From its light weight and transparency to incredible strength and flexibility, this demanding yet relatively cheap material is an obvious choice for a wide variety of commercial applications.

Strength and durability

Polycarbonate boasts fantastic mechanical properties. Its strength and durability make it an excellent choice for items that will undergo significant wear and tear. With such a high impact resistance and natural bendability, PC parts do not deform or break, so they can stand up to a variety of demanding applications. By comparison, other transparent thermoplastics, like PMMA, will crack and break if bent. This makes polycarbonate an excellent choice for making functional prototypes, especially where transparency and non-conductivity are desired.

Temperature resistance

Polycarbonate stands out for its excellent heat resistance. It is able to withstand high temperatures without deforming, making it perfect for parts that will be exposed to heat.

Optical clarity

Polycarbonate’s transparent nature and light transmittance allow for a number of unique applications in the creation of high-quality clear or translucent objects with beautiful looks. In contrast to PETG that is also transparent, PC provides far better impact and temperature resistance.


How to print with polycarbonate

So, what is the workflow when 3D printing with polycarbonate?

Setting up your printer. To print with polycarbonate, you will need a 3D printer capable of reaching high temperatures. You may also need a heated bed and an enclosed print area to maintain a constant ambient temperature.

Temperature settings. Polycarbonate generally prints at a higher temperature than other plastics, often between 260–300 °С, so make sure the extruder is capable of reaching these values.

Post-processing. As with other 3D printing materials, this stage involves steps like cleaning up the print, removing supports, and sanding the object to make it smooth and ready for use.


Applications of polycarbonate 3D printing

Polycarbonate has found its way into various industries, from automotive to aerospace, thanks to its unique properties.

Outside of 3D printing, it is commonly used to make various household products, such as CDs and DVDs, water dispensers, electronic display screens, phone and computer cases, food containers, and much more. Due to its high strength, impact resistance, and transparency, PC is also found in manufacturing sunglass lenses, scuba masks, bike and motorbike helmets, car body parts, riot gear, and even bulletproof glass.

As for proper 3D printing uses, polycarbonate is a perfect option for engineering applications requiring its high strength and flexibility. PC based filaments are frequently used for projects that need to handle higher temperatures and strong impacts, like 3D printed car parts.


Challenges of polycarbonate 3D printing

While polycarbonate 3D printing offers many benefits, it is not without challenges. Depending on your setup, PC can be tricky to print with due to its high-temperature requirement, sensitivity to cooling, hygroscopic properties, and adhesion issues.

High printing temperature. Standard 3D printers are not always capable of achieving the processing temperatures required that should be above 300 °C. Most will also struggle to maintain the heated bed temperatures at the right level. Plus, an all-metal hotend is needed to effectively 3D print with polycarbonate. Thus, if you have a standard 3D printer, certain modifications may be required.

Warping issues. Since PC is extremely prone to warping even in comparison with ABS, it requires precise printing settings to avoid this.

Hygroscopicity. When left out in the open, polycarbonate absorbs a lot of moisture from the air, which worsens its 3D printing characteristics. PC based filaments must be kept in airtight, dry conditions at all times.

Sensitivity to UV rays and hydrolysis. Polycarbonate is degraded by sunlight and reacts poorly to water, which makes it unsuitable for any outdoor applications.


Recommendations for 3D printing polycarbonate

As you can see, polycarbonate 3D printing does come with a unique set of challenges, but with the right settings and practices, these can be easily overcome. When taking into account several important factors, such as a stable temperature, slow print speed, and low cooling rate, you will be able to produce successful PC prints.

Ambient temperature

When dealing with polycarbonate, ambient temperature plays a crucial role. It is essential to maintain a controlled, warm environment to prevent warping or cracking of the printed parts. For this, your printer needs an enclosure that is consistently heated up to 60–70 °C. In addition, the temperature of the print bed should be kept at 90–120 °C to avoid warping and eliminate potential delamination issues.

Nozzle temperature

Polycarbonate requires a higher nozzle temperature compared to other thermoplastics, typically around 260–310 °C. This particular material takes a long time to melt, so high printing temperatures ensure a uniform filament flow. Another important part is fine-tuning. When the printing temperature is too low, this will lead to quality issues, like layer separation, cracking, warping, etc. Still, if the nozzle temperature is too high, there is a risk of stringing and oozing.

Print speed

Due to its high glass transition temperature, PC can be printed at a lower than optimal temperature, but more slowly, in direct proportion to the temperature selected. Thus, at 265 °C, polycarbonate will provide decent results at a speed of 30 mm/s. It also works the other way around: with a higher extruder temperature, you can experiment with a faster print speed up to 60 mm/s.

Bed adhesion

Using a heated bed with an adhesion solution, such as Kapton tape, ABS slurry, borosilicate glass, or special build surface sheets like PEI, can ensure your model properly sticks to the bed throughout the printing process. Plus, when printing the first layer, it is recommended to lower the print speed and turn off cooling completely. Also, try increasing the layer height and width by 50% to further improve bed adhesion.


Polycarbonate is highly hygroscopic, so it is crucial to properly store your filament and consider drying it before printing. Otherwise, it will cause problems with extrusion due to bubbles and inconsistent flow, which can result in a ruined design of your models.

Filament quality

Not all polycarbonate filaments are equal in quality. Choosing decent consumables can significantly improve your 3D printing experience and final outcomes.

Bottom line

Polycarbonate offers immense potential for 3D printing, with its superior strength, heat resistance, and optical clarity. With a glass transition temperature of around 150 °C, nothing in the FDM range can compete with it. Recommended for durable, lightweight, flexible, and transparent parts that must withstand tough conditions, it is great for a variety of high-temperature engineering applications. However, careful considerations and settings adjustments are needed to successfully print with this material.


Are parts 3D printed in polycarbonate strong?
Yes, polycarbonate is now one of the toughest materials available for desktop 3D printers. Compared to an ABS filament with a tensile strength of about 32MPa, polycarbonate filaments on the market boast a tensile strength of 65MPa.
How to reduce warping when printing with polycarbonate?
To stop polycarbonate from warping, it is necessary to ensure a perfect first layer. Carefully adjust the temperature of the build plate and make sure you are using a proper print bed material. Larger prints require a heated enclosure that helps prevent uneven cooling, which is a major cause of warping. Also, it is important to use low cooling settings.
How to store polycarbonate filament properly?
Since polycarbonate is extremely hygroscopic and loses its properties due to moisture, you want to ensure it is stored in a completely dry environment. An airtight container with desiccants is an ideal way to store polycarbonate filament. You can either use vacuum-sealed bags or a dedicated filament dryer box.
Is it safe to 3D print polycarbonate?
3D printing polycarbonate is relatively safe as long as you follow safety standards, such as printing in a well-ventilated room to reduce your exposure to gasses and fumes emitted from this high-temperature filament. In terms of odor, it is better than ABS, but still not odorless.
Does polycarbonate need cooling?
Polycarbonate does not need cooling to print. Even during the process itself, the fan speed should be kept very low, not higher than 40%. Without a heated enclosure, polycarbonate is particularly prone to curling, warping, and shrinkage. These issues will only get worse due to strong cooling, with potential cracks in the printed model.
