Engineering filament

Types and Characteristics of Engineering Filaments

Engineering plastics are materials with exceptional mechanical and physical properties such as stiffness, impact resistance, and low flow rate, making them indispensable for the production of items like gears, enclosures for electronic measuring devices, automotive parts, and more.

In general, engineering plastics for 3D printing possess the following characteristics:

• High wear resistance
• Chemical resistance
• Easy to machine
• Excellent durability under prolonged mechanical stress
  
  

Engineering Filaments Include:

ASA – A highly durable material, resistant to various environmental factors. ASA plastic is unaffected by UV rays, withstands temperature fluctuations, and does not yellow when exposed to the outdoors. This material is ideal for printing objects that are in constant contact with external elements, such as automotive parts and outdoor electrical outlets.

Nylon – A synthetic material for 3D printing, nylon is known for its strength, flexibility, and durability. It is used to produce parts that will endure constant mechanical stress. For example, gears, bushings, and components for household appliances are commonly printed from nylon.

PBT – A crystallizing polymer that belongs to the family of saturated polyesters, PBT is widely used as an engineering plastic. Its applications include mechanical engineering, automotive manufacturing, electrical and electronic industries, radio technology, precision mechanics, household appliances, and consumer goods.

PC – The strongest plastic for 3D printing, polycarbonate (PC) can withstand both mechanical impact and high temperatures, making it highly versatile. PC filament is transparent, as are the items printed with it. It is often used to create products like swim masks, screens, commercial products, as well as electrical, mechanical, and automotive parts.

PET – This material has gained popularity among makers worldwide. It is resistant to mechanical damage and has lower shrinkage compared to ABS and PLA. However, PET is sensitive to moisture, meaning printed objects and filament should not be stored in damp environments.

PP – A non-toxic and durable material used in packaging, plumbing products, tableware, medical supplies, and other items that require high resistance to mechanical stress.

SAN – A combination of transparency, chemical resistance, strength, and lightness. It offers high rigidity, excellent dielectric properties, and resistance to scratching, making it a durable and versatile material for various applications.
