Welcome to another exciting 3D printing exploration! Today, we’re diving into the world of aerospace-grade 3D printing with PEC-C from 3DX Tech. This remarkable material, known for its mechanical prowess and chemical resistance, has gained substantial attention in various industries. Let’s take a closer look at what makes PEC-C stand out.
The Power of PEC-C
PEC-C stands for Polyetheretherketone Carbon. It’s a type of PEEK (Polyetheretherketone) that comes in crystalline form, making it a superior choice for specific applications. PEC-C is renowned for its exceptional mechanical abilities and wide temperature tolerance, making it a versatile option for diverse testing and application environments.
One of the standout features of PEC-C is its impressive chemical resistance, making it an ideal candidate for industries like medical and manufacturing. It’s a high-performance material designed to thrive in demanding conditions.
Amorphous vs. Crystalline
It’s essential to understand the distinction between amorphous and crystalline forms when it comes to PEC. PEC comes in two varieties: PEC-A (amorphous) and PEC-C (crystalline). PEC-C is the focus of our discussion due to its enhanced mechanical properties compared to its amorphous counterpart.
Applications of PEC-C
PEC-C is a material with a wide range of applications across various industries. Here’s where you’re likely to encounter it:
Medical Industry
PEC-C is a top choice for producing tools, invasive implants, testing devices, and medical component housings. Its exceptional sterilizability and chemical resistance make it a valuable asset in the medical field.
Automotive Sector
In automotive applications, PEC-C shines in the production of brackets, linkages, spacers, caps, and more. Its ability to withstand a broad range of temperatures and environments makes it an excellent choice for these components.
Aerospace
Boeing has certified PEC-C for in-flight parts, marking a significant advancement in aerospace applications. Its robust properties and heat resistance make it an ideal choice for critical components in the aerospace industry.
Food Industry
PEC-C can be used for plating, creating Tupperware and food contact containers that are safe for reheating and microwaving. Its resistance to chemicals and heat is a valuable asset in food-related applications.
Printing Requirements
Printing with PEC-C requires specific conditions to harness its full potential. Here are the key parameters:
- Nozzle temperature: 345°C to 390°C
- Bed temperature: 110°C to 160°C
- Heated chamber: 80°C or higher
For reliable adhesion, a high-temperature adhesive like nano polymer adhesive is recommended for your print bed.
Drying PEC-C
Moisture is the enemy of 3D printing materials. PEC-C is no exception. Before using PEC-C, it’s essential to dry it to remove any absorbed moisture. You can find dedicated equipment for drying PEC-C on our website, including vacuum chambers and ovens that expedite the process.
Material Specifications
Here are some essential material specifications for PEC-C:
- Heat deflection temperature: 182°C
- Glass transition temperature: 162°C
- Melting point: 335°C
- Annealable: Yes, for enhanced properties
Annealing can transform PEC-C from its clear, translucent state to a tan, crystalline form, significantly enhancing its heat deflection and overall strength.
Strength Characteristics
PEC-C is renowned for its impressive strength. Here’s a snapshot of its tensile modulus:
- Unfilled PEC-C: 3200 megapascals (MPa)
- PEC-C with carbon fiber: 9560 MPa
Keep in mind that the orientation and design of your printed parts can influence their strength, and there may be variations in the z-axis.
Environmental Resilience
PEC-C exhibits excellent resistance to various environmental factors:
- UV resistance: Suitable for outdoor applications
- Hydrolytic resistance: Effective in water without degradation
- Chemical compatibility: Resistant to gasoline, oil, acetone, chlorine, and more
- Electrical properties: Highly insulative, static dissipative with carbon fiber
Biocompatibility and Sterilization
PEC-C has certifications for biocompatibility, making it suitable for certain medical applications. Certified grades are available for implantation purposes, and the material is designed to endure various sterilization methods, including autoclaving and gamma radiation.
Concluding Thoughts
PEC-C is a remarkable material that opens up new possibilities in 3D printing, especially for aerospace, medical, automotive, and food-related applications. Its combination of mechanical strength, chemical resistance, and ease of printing makes it a valuable addition to the world of additive manufacturing.
