PET is a versatile choice for creating strong, durable, and resilient mechanical parts, food packaging, and bottles. Engineered to meet your needs with excellence and sustainability in mind, PET filament is a versatile solution for a wide range of applications.
About PET Filament
Polyethylene terephthalate (PET) is the most common thermoplastic polymer resin used in clothing fibers, containers for liquids and foods, and thermoforming for manufacturing. When combined with glass fiber, it is engineered for resins. PET filament is a remarkable material made from polyethylene terephthalate for 3D printing. It is also the most widely recycled plastic, known for its infinite recyclability.
What is PET?
PET is a recyclable polymer that can be manufactured using conventional plastic production methods, making its production both efficient and scalable. The material is celebrated for its high melting temperature and resistance to impact, making it ideal for a wide range of applications, including those requiring mechanical strength.
Types of PET Filament
PET filament is available in various formulations, each offering distinct characteristics. Here are some popular types:
- PETG: A modified version of PET that includes glycol, offering enhanced durability and impact resistance. PETG is renowned for its ease of printing and is less prone to warping, making it an ideal material for functional parts and prototypes.
- Recycled PET: Made from post-consumer recycled materials, this filament is an eco-friendly option that provides the same strength and transparency as new PET.
- Transparent PET: Offers high clarity and is perfect for applications where visibility and aesthetics are crucial, such as light fixtures and display cases.
Recycling PET
PET stands out for its recyclability. It can be collected and reprocessed into new filament, reducing waste and promoting a circular economy. PET is widely accepted in recycling programs, making it a sustainable choice for environmentally conscious makers.
General Properties of PET
PET filament boasts several notable properties:
- Heat Deflection Temperature (HDT): 158 °F (70 °C)
- Density: 1.38 g/cm³
- Tensile Strength: 60 MPa
- Flexural Strength: 85 MPa
- Impact Strength (Unnotched) IZOD: 120 J/m
- Shrink Rate: 0.2-0.5% (0.002-0.005 in/in)
Advantages of PET Filament
PET filament offers numerous benefits, making it a go-to material for many 3D printing projects:
- Strength and Durability: PET is well known for its exceptional mechanical properties, making it well-suited for demanding applications.
