What Makes Polycarbonate the Ultimate Choice for 3D Printing Durability?


In any production process, material selection is key not only to making a suitable and durable product, but also to ensuring successful manufacturing. Additionally, material costs have the greatest impact on the final cost of a product. Beautiful, 3D printing is versatile, thanks to the variety of materials and technologies available. However, this availability comes at a price, and the cost can be quite high.
Polycarbonate (PC) is a high-strength material suitable for Taylor environmental and engineering applications. It has extremely high heat and impact resistance. Polycarbonate also has a glass transition temperature as high as 150°C. This means focusing on maintaining its differential structure at that temperature, making it suitable for high-temperature applications. It can also bend without breaking and is typically used in applications that require some flexibility. In this article, let us explore what aspects of polycarbonate (PC) have become the ultimate choice of 3D printing materials due to its excellent performance and characteristics. What are the reasons for these properties in batch 3D printing materials?

What Is Polycarbonate 3D Printing?

Polycarbonate 3D printing is a manufacturing process that utilizes polycarbonate (PC) material to create three-dimensional objects through additive manufacturing technology (layer-by-layer). The main 3D printing technology used to create objects made of this material is called fused deposition modeling (FDM). It uses polycarbonate filament as the raw material to build up the desired shape.

Polycarbonate (PC) boasts remarkable attributes—it’s robust, with an ultimate tensile strength of 70 MPa and yield strength of about 63 MPa, and can withstand both high heat and impacts, maintaining structural integrity even at temperatures up to 150 °C (its glass transition temperature). Owing to these properties, PC has found extensive utility in a myriad of industries such as: aerospace, automotive, electronics, medical devices, and consumer goods.

What are the advantages of polycarbonate?

  • Transparency: The transparency of PC is very high, and its light transmittance is also excellent. It is often used in applications that require high optical clarity, such as eyeglass lenses and transparent protective shields.
  • Impact Resistance: A notable property of this material is its excellent impact resistance. This characteristic makes it resistant to impacts in various harsh environments. It is extremely stable and is particularly suitable for applications where safety and durability are critical, such as bulletproof glass, safety goggles and car headlight lenses.
  • Heat resistance: PC can withstand extremely high temperatures without melting or deforming. This device has a high glass transition temperature and is particularly suitable for applications that require working in high temperature environments, such as microwave oven-safe cookware and LED lampshades.
  • Lightweight: Although this material is very strong, it is relatively lightweight. Due to its light weight, lightweight design can be carried out without changing the original structural size and shape. Therefore, this technology is widely used to reduce weight in various industries such as aviation, aerospace, and automobiles.
  • UV Resistance: PC exhibits excellent resistance to ultraviolet (UV) radiation, an application that might involve panels in greenhouses or protective covers for outdoor equipment.
  • Electrical insulation: It is an excellent electrical insulator that is often used in electronic and electrical components to avoid short circuits and potential electrical risks.

What Makes Polycarbonate the Ultimate Choice for 3D Printing Durability?

Polycarbonate (PC) has become the ultimate choice for 3D printing durability, mainly due to its many excellent properties and characteristics, which make it stand out among many 3D printing materials.

1.High impact resistance

Polycarbonate exhibits extremely excellent mechanical properties. Its exceptional strength and durability make it the first choice for items that have endured heavy damage. With the help of extremely high impact resistance and natural bending, PC components maintain their original shape without deformation or breakage, which allows them to adapt to and cope with a variety of harsh application scenarios. In contrast, other transparent thermoplastics (such as PMMA) are prone to cracking and breaking due to bending. In this case, polycarbonate is seen as the best option for making functional prototypes, especially where transparency and non-conductivity need to be maintained.

2.temperature adaptability

Polycarbonate stands out for its excellent high temperature resistance. This design has the ability to maintain shape deformation under high temperature conditions and is particularly suitable for the production of components that will face high temperature exposure.

3.Optical transparency

Due to its excellent transparency and light transmission, polycarbonate has many special uses when designing high-quality, visually stunning transparent or translucent materials. Compared with PETG with the same transparency, PC shows better ability to withstand impact and high temperature.

What is the step-by-step process for 3D printing polycarbonate?


In this process, computer-aided design (CAD) software is first used to build a digital 3D model of the desired object. This model is used as a blueprint for the subsequent printing process and defines the shape, size and internal structure of the object. Then use slicing software to divide the 3D model into thin horizontal layers. Develop specific specifications for each layer. This includes the path the printer nozzle should follow to ensure precise deposition of material.


After the design is completed, the 3D model can be printed. This includes work on scaling, orientation, and positioning the model within the constructed volume. Additionally, support structures can be created to provide stability between overhangs and complex features when printing.

3.Printer settings

The 3D printer must be calibrated and prepared before printing. It involves a series of basic links to ensure optimal printing conditions. It is critical to confirm the completeness of the printing bed. This step is especially important when using materials that are sensitive to bed adhesion, such as polycarbonate. Polycarbonate is prone to warping during the printing process, which can cause consistent layer adhesion.
In addition to bed leveling, it is also crucial to ensure that the nozzle is clean and free of residues that may affect the extrusion process. Proper nozzle maintenance is key to accurate, high-quality printing. In addition, choosing appropriate printing parameters is key. Especially with polycarbonate, accurate temperature settings are critical in the extruder and build chamber. Polycarbonate has a relatively high glass transition temperature and requires careful temperature management to prevent warping and ensure proper layer bonding.


The actual printing process begins with the 3D printer’s extruder or nozzle heating polycarbonate filament to its melting point. The nozzle then moves to the print position defined by the machine instructions, depositing the molten material onto the print bed, layer by layer. As each layer is deposited, the molten polycarbonate merges with the previously deposited layer, forming a strong bond between them. This layer-by-layer approach leads to the step-by-step construction of the final object.
After all layers are printed, the object will completely cool and solidify. Depending on the complexity and size of the print, this may take varying amounts of time. To maintain ideal printing conditions, other mechanisms can be employed to regulate temperature, including the use of fans or heated build chambers.


Once printing and cooling are complete, the object is removed from the build plate. Post-processing may involve removing excess support material, cleaning parts, and addressing any imperfections on the surface. This depends on the complexity of the design and the presence of supporting structures.


To achieve the desired appearance and functionality, finishing steps may be required. This may include sanding smooth surfaces, painting or coating to enhance aesthetics, and adding any required assembly parts.

Polycarbonate 3D printing allows for rapid prototyping and customization, making it ideal for low volume production runs and tailored designs.Traditional 3D printing methods often require molds and tooling, limiting customization and cost-effectiveness for small runs.

Comparison of polycarbonate and PLA printing materials

PLA (polylactic acid) is a thermoplastic made from organic materials such as corn, sugar cane, and other plant matter. It is one of the most popular filament options for 3D printing and is a favorite among beginners due to its low melting point and low shrinkage. This makes it easy to use since it doesn’t require a fancy hot end or even a heated print bed to print.


Stiffness PCPLA
Tensile StrengthPC material has excellent tensile strength and can withstand large tensile forces without breaking easily. This high-strength property makes PC materials widely used in many fields, such as electronics and electrical, automobile manufacturing, etc.The tensile strength of PLA is lower than that of PC. Although it does have some strength, it is not typically used in applications that require it to withstand high tensile loads.
Yield StrengthYield strength is an assessment of the ability of a material to begin plastic deformation when subjected to external forces. PC material has excellent yield strength and can withstand large forces without plastic deformation.PLA has a relatively low yield strength, so it is more prone to plastic deformation when subjected to external forces.
Impact StrengthPC material has excellent impact resistance and can maintain structural integrity when impacted and is not easy to break.PLA has lower impact strength compared to PC. Although it also has some impact resistance, it is more susceptible to damage when subjected to strong impacts.
Other PC materials also have excellent rigidity and hardness, and these properties are closely related to strength. PC has high hardness and is resistant to scratches and wear.PLA has relatively low rigidity and hardness, but its degradability and environmental friendliness give it unique advantages in certain applications.

How to choose between polycarbonate and PLA?

  • Strength Requirements:If your parts need to withstand high strength, high impact or high pressure, then PC is a better choice. PC’s high strength and rigidity allow it to withstand these stresses, and its chemical and abrasion resistance also allow it to perform well in harsh environmental conditions.
  • Cost Matters:If price is your main consideration, PLA may be a better choice. PLA generally has lower material costs than PC and is easier to print, which means you may not need to invest as much time and resources in adjusting print settings or troubleshooting print problems.
  • Printing Technology:If you are new to 3D printing or don’t have much printing experience, PLA may be a better choice. PLA is simpler to print and typically does not require a heated bed or special print setup, making it a good choice for beginners.
  • Application Scenarios:Finally, you need to choose the most appropriate material based on the specific use of the part. If the part must be used in harsh environmental conditions, or needs to withstand high pressure or friction, PC may be a better choice. If the part is intended primarily for education, art, and decoration, or if rapid prototyping is required, PLA may be a better choice.
How tensile strength relates to polycarbonate 3D printing

Polycarbonate compared to other 3D printing materials

The unique properties and superior performance of this material become even more apparent when we compare PC to other plastics used in 3D printing.

  • ABS (Acrylonitrile Butadiene Styrene): ABS is another widely used 3D printing material that offers good impact resistance and durability. However, PC’s strength, heat resistance, and toughness exceed ABS. Polycarbonate has an excellent heat distortion temperature, which means it can handle high-temperature applications where ABS may warp.
  • Nylon (Polyamide): Nylon is widely recognized for its strength and flexibility comparable to PC. However, polycarbonate is superior at making printed parts rigid and isotropic. Nylon readily absorbs moisture from the air, which affects its strength and dimensional stability. In comparison, PC is less hygroscopic and has better dimensional stability.
  • PETG (polyethylene terephthalate): PETG combines the ease of printing of PLA with the strength of ABS. But overall, PC performance is superior. While PETG offers decent durability, heat resistance, and flexibility, polycarbonate outperforms in these properties. PC has higher impact resistance and heat deflection temperature, making it a stronger material for demanding applications.

All in all, while each plastic material has its benefits and applicable uses, PC’s superior durability, toughness, and rigidity make it suitable for 3D printing.
