Candour PPS-CF Black 0,75 kg

Product Description

Candour PPS-CF is a top-tier engineering filament made of PPS (polyphenylene sulfide) reinforced with carbon fibers, designed for the most demanding industrial and functional applications. It combines extreme thermal and chemical resistance with very high stiffness and dimensional stability.

The material composition, properties, and coloring of this filament are identical to the original Bambu Lab PPS-CF – both are produced by the same manufacturer. The difference is in the packaging:

• Candour spools do not have an NFC/RFID tag, so the printer will not identify them automatically.
• Candour spools have a different design than original Bambu Lab spools, and therefore cannot be used as refill spools.
• When searching or for illustrative photos, we recommend using images of Bambu Lab PPS-CF of the same name and color, as the material is identical.

Thanks to its very low water absorption, PPS-CF minimally changes dimensions over time and maintains its mechanical properties even in humid environments. It is therefore suitable for long-term loaded parts in the automotive, electrical, mechanical, and aerospace industries.

Main Features

• Ultra-high heat resistance – heat deflection temperature (HDT) up to approx. 264 °C at 0,45 MPa.
• Long-term operation above 200 °C – suitable for parts near engines, heating elements, or other heat sources.
• Carbon Fiber (CF) reinforcement – high stiffness, strength, and dimensional stability.
• Excellent chemical and corrosion resistance – resists many solvents, oils, fuels, and industrial chemicals.
• Inherent flame retardancy / high flame retardant class (equivalent to UL94 V-0 in the reference Bambu Lab PPS-CF).
• Very low moisture absorption – minimal swelling and dimensional change, stable properties over time.
• Dimensional stability and minimal warping – suitable for larger precise parts.
• Professional engineering material – ideal for industrial and functional prototypes.

Recommended Use

Candour PPS-CF is particularly suitable for:

• Automotive parts – brackets, covers, engine compartment components, parts near exhausts or radiators.
• Jigs, fixtures, and machine accessories – jigs, fixtures, and clamping parts near heat or chemicals.
• Electrical and electronic components – housings, spacers, functional parts in high-temperature environments.
• Industrial and mechanical components – gears, bearing housings, functional prototypes with high mechanical stress.
• Other structural and functional parts in demanding environments where common materials (PLA, PETG, PA-CF) are insufficient.

This filament is intended for more experienced users who have an enclosed, heated printer and can handle printing at high nozzle and bed temperatures.

Printing Recommendations

Specific values may vary by printer and conditions, but based on the parameters of the reference Bambu Lab PPS-CF:

• Nozzle temperature: approx. 310–340 °C
• Bed temperature: approx. 100–120 °C
• Enclosed print chamber: strongly recommended, ideally heated
• Max. recommended print speed: up to 100 mm/s (for surface quality and strength)
• Dry filament is a necessity – dry the PPS-CF before printing (higher temperature and longer drying time than common materials)
• Abrasion-resistant nozzle – use a hardened steel, hardened brass, or otherwise durable nozzle due to the abrasive carbon fibers.

With improper drying or an insufficiently heated environment, filament snapping, poor layer bonding, or increased internal stress may occur – therefore, it is worth paying maximum attention to print preparation.

Candour Spool Features

• Without NFC/RFID tag – the filament is not automatically recognized by the printer.
• Different spool design compared to Bambu Lab – cannot be used as a refill spool for the original Bambu Lab system.
• Suitable for standard spool holders and external feeders.

For illustrative photos and an idea of the color, you can use images of Bambu Lab PPS-CF Black filament, as the material and shade are identical.

Technical Specifications (Material)

* Values are based on reference parameters of Bambu Lab PPS-CF of the same material type.

Who is Candour PPS-CF suitable for

• Professional users and industry looking for a replacement for machined technical plastics.
• Advanced enthusiasts who need a material with maximum thermal and chemical resistance.
• Users who want a material of the same quality as Bambu Lab PPS-CF but prefer different packaging or integration into their own workflow.

Key features:

• Identical composition and properties as Bambu Lab PPS-CF (same manufacturer, same material and color)
• Ultra-high heat resistance – HDT approx. 264 °C, long-term operation above 200 °C
• Carbon fiber reinforcement for top stiffness, strength, and dimensional stability
• Excellent chemical and corrosion resistance to oils, fuels, and many solvents
• Very low moisture absorption – stable dimensions and properties over time
• Suitable for demanding industrial and automotive applications, jigs & fixtures, and functional parts
• Spool without NFC/RFID tag, different from Bambu Lab – cannot be used as a refill spool
• Ideal for enclosed FDM printers with a high-temperature hotend and abrasion-resistant nozzle
