FILAMENTS – INDUSTRIAL

 

FILAMENTS – INDUSTRIAL

PLEASE NOTE: THIS SECTION IS CURRENTLY UNDER DEVELOPMENT AND IS NOT COMPLETE.

If the commercial filaments can rightly be deemed the ‘workhorses’ of the 3D printing community, industrial filaments are the thoroughbreds.

Industrial filaments are filaments are composed of the highest grade thermoplastics and composite materials and represent some of the strongest, most chemical and heat resistant materials currently available. As such, they typically require demanding printer and print settings, and sometimes equally demanding post-processing efforts.

The list of industrial filaments includes:

 



Peek2.jpgPeek2.jpg

PEEK (Polyether Ether Ketone)

RECOMMENDED PRINT SPEED: 20-50 mms
RECOMMENDED EXTRUDER TEMPERATURE: 375°C–450°C (chamber heat of 90°C+ is recommended)
RECOMMENDED BED TEMPERATURE: 120°C–140°C

PEEK polymers are obtained by step-growth polymerization. PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. PEEK is regarded as one of the highest performing engineering thermoplastics in the world.

PEEK Filament has unique properties because it does not come into contact with water during the production process and is directly packaged in a vacuum packaging. These properties make the PEEK Filament particularly suitable for usage in FDM and FFF 3D printers. The material has an excellent adhesion between layers which results in great improvement of the impact resistance, strength, durability and the printing process.

PEEK has some compelling features, especially when it comes to producing functional prototypes and parts;

  • Highly resistant to extreme temperatures up to 260°C (480°F), as well as corrosive fluids, gases, and high pressure

  • Insoluble in common solvents, preventing it from hydrolysis and allowing it to be used without any degradation from high-pressure water or steam

  • Lightweight: PEEK has an inherently low specific gravity of 1.3 g/cm3, less than half that of aluminum and one-sixth that of steel.

  • High self-lubrication ability and low friction

  • Outstanding creep resistance

  • Very little attrition

  • Good dimensional stability

  • Low flammability and little smoke emission when combusting

  • Exceptional insulation properties

  • Excellent sterilization resistance at high temperature

  • Fully bio-compatible

Some of these resistivity properties can be further enhanced by combining PEEK with composite materials like glass fibre, graphite, molybdenum disulfide or carbon-reinforcements.

PEEK Filament meets the European regulations EC No. 1935/2004, EC No. 2023/2006 and EC No. 10/2011 concerning plastic materials and articles coming into contact with food and is also compliant with the FDA (Food and Drug Administration) for food contact. Any colorants blended in PEEK filament also meet these European and US regulations.

Because of its amazing combination of features, PEEK is used to fabricate items used in demanding aerospace, automotive, oil and gas and medical applications.

POLYCARBONATE (PC) – PC MAX and PolyLite PC

RECOMMENDED PRINT SPEED: 30-90 mms
RECOMMENDED EXTRUDER TEMPERATURE: 270°C–310°C
RECOMMENDED BED TEMPERATURE: 90°C–110°C

Polycarbonate (PC) is extremely durable and resistant to both physical impact and heat, able to withstand temperatures of up to 110°C. It’s also transparent, which explains its use in commercial items such as bullet proof glass, scuba masks, and electronic display screens.

Despite some similar use cases, PC shouldn’t be confused with acrylic or plexi-glass, which shatter or crack under stress. Unlike these two materials, PC is moderately flexible (though not as much as nylon, for example), allowing it to bend until eventually it deforms.

PC 3D printer filament is hygroscopic, able to absorb water from the air, so remember to store it in a cool, dry place to ensure better quality prints. Additionally, polycarbon filament is odorous when being printed, so it is a good idea to print using an enclosed printer, or in a well ventilated area.

PolyMaker PC 3D Printer Filament Properties:

  • Strength: Very High| Flexibility: Medium | Durability: Very High

  • Difficulty to use: Medium

  • Shrinkage/warping: Considerable

  • Soluble: No

  • Food safety: Not food safe

PolyMaker PC is an ideal 3D printer filament for parts that need to retain their strength, toughness, and shape in high-temperature environments, such as electrical, mechanical, or automotive components. Also try to take advantage of its optical clarity in lighting projects or for screens.

TAULMAN ALLOY 910

RECOMMENDED PRINT SPEED: 30-90 mms
RECOMMENDED EXTRUDER TEMPERATURE: 270°C–310°C
RECOMMENDED BED TEMPERATURE: 90°C–110°C

Alloy 910 is a very high tensile filament that provides enough elongation to maintain a high degree of durability. Taulman 910 is designed to be extremely strong without any composite fillers, and is good for use in high temperature and high durability applications such as industrial parts and robotics. It is a high quality filament designed to be easy to print with.

Alloy 910 can be used for industrial parts currently being made of high tensile polymers, large motor mounting, industrial vibration isolators and damping components, sand blasting masking, electroplating supports and hangers, chemical dip and tank supports, high end gears and cams, chemical resistant covers, frames and other parts that require high strength and stiffness.

 



PEKK.jpgPEKK.jpg

PEKK (PolyEtherKetoneKetone)

RECOMMENDED PRINT SPEED: 20-50 mms
RECOMMENDED EXTRUDER TEMPERATURE: 345°C–375°C
RECOMMENDED BED TEMPERATURE: 120°C–140°C

A leading material in the PAEK family, PEKK has exceptional mechanical, thermal, and chemical resistance properties, while being substantially easier to print than PEEK.

PEKK was created to be printed using the many new open-source printer platforms currently available on the market.  Compare to Stratasys® Antero™ PEKK and you will realize this is a great opportunity to take advanced of an aerospace-grade material without being tied to an expensive closed-source system.  3DXTech® and Stratasys® both purchase PEKK resin from the same supplier, so what’s the difference?  Freedom, cost, and innovation.

Firewire® PEKK features:

  • Glass Transition Temp (Tg) of 162°C (20°C higher than PEEK)

  • Melt Temp (Tm) of 335°C  (allows for lower print temps than PEEK)

  • Inherent flame resistance (UL94 V-0)

  • Low smoke generation for aerospace applications

  • Outstanding mechanical, thermal, and chemical resistance

  • Continuous Use Temperature (CUT) of 260°C, higher for short durations

  • Excellent resistance to a broad range of chemicals, such as those used in the oil/gas, automotive, aerospace, industrial, and chemical processing industries

 



CFPEKKfilament2.jpgCFPEKKfilament2.jpg

CARBON FIBER PEKK (AEROSPACE) 3D PRINTING COMPOSITE FILAMENT

RECOMMENDED PRINT SPEED: 30-90 mms
RECOMMENDED EXTRUDER TEMPERATURE: 355°C–385°C
RECOMMENDED BED TEMPERATURE: 120°C–140°C

Made using Kepstan® PEKK and Toray® Aerospace-Grade T800 24K Chopped Carbon Fiber.  This compound was created for extreme applications where exceptional thermal, mechanical, and chemical resistance properties are required.  

CarbonX® CF-PEKK has a wider processing window than PEEK and typically prints with extruder temps between 360-390°C, whereas CF-PEEK often requires extruder temps above 400°C.  CarbonX™ PEKK has a lower rate and degree of crystallinity than PEEK, which aids in its ease of printing.
