3DXTECH FIBREX PPA+GF15 1.75mm/750g

FibreX PPA+GF15 3D Printing Filament

FibreX PPA+GF15 is a glass fiber reinforced polyphthalamide (PPA) with exceptional thermal, mechanical, and chemical resistance. PPAs are a special type of high-temperature nylon (HTN) – semi-aromatic polyamides – whose molecular structure gives significantly higher properties than aliphatic polyamides like PA6, PA66, PA11, and PA12, which are typically used in 3D printing. PPAs have significantly higher glass transition temperatures (Tgs), melting temperatures (Tms), and heat deflection temperatures (HDTs) than typical aliphatic nylons such as PA6 or PA12. The chemical structure of PPA reduces the amount of moisture absorbed as well as the rate at which it is absorbed, resulting in a more rigid printed part when exposed to ambient or end-use conditions.

Benefits of PPA+GF15 PPA High-Temp Nylon include:

• High thermal properties, with a Tg of 125°C, HDT of 260°C, and a Tm of 305°C
• Excellent strength and stiffness over a wide temperature range, up to 260°C, superior to ULTEM™ PEI
• Very low moisture absorption ensuring better retention of mechanical properties even when exposed to humid environments
• Exceptional chemical resistance to alcohols, acids, automotive and aircraft fuels, oils, lubricants, brake and transmission fluids, anti-freeze, and Zn/Ca chlorides

Recommended Print Settings:

• Extruder: 325-345°C
• Bed Temp: 120-140°C
• Nozzle: We currently recommend a hardened steel nozzle with a minimum diameter of 0.4mm
• Other: Ideal layer height is 60% of nozzle diameter. We do not recommend printing layers shorter than 0.2mm with carbon fiber reinforced filaments
• Bed Prep: Magigoo Bed Prep and 3DXTECH Polyimide Tape
• Heated Chamber: Recommended
• Supports: AquaTek™ X1 USM Water Soluble Support is designed to work with complex model geometries
• Drying Instructions: 120°C for 4 hours

Glass Fiber Reinforced Filament

What is it? - Glass fibers are reinforced into the polymer during manufacturing and aligned along the axis of the filament. This, along with their physical composition, gives this material enormous strength and mechanical properties.

What does it do? - Glass fiber reinforcement provides the material with many desirable properties: high strength, high stiffness, high chemical resistance, and low thermal expansion

How does it work? - Reinforcing plastic with glass fibers yields a 3D printing filament that displays the best properties of both glass fiber and the chosen plastic.

What is it good for? - Ideal for all applications that require strength and stiffness. For these reasons, glass fiber reinforced filament is very popular in the automotive, mechanical, civil engineering, and research industries.

Abrasive Material

This material is particularly abrasive among 3D printing filaments. Users may find that standard brass nozzles are eaten through very quickly compared to standard wear. Once worn, the nozzle diameter will expand inconsistently, and the printer will experience extrusion issues.

For this reason, it is highly recommended to print this material through a hardened steel nozzle rather than with a softer metal. Hardened steel nozzles can often be inexpensive and easy to install, depending on your printer manufacturer's instructions.
