PPS-CF filament sits at the top of our heat deflection ladder at 245°C, for parts that face heat, sustained load and harsh chemicals at the same time. It suits experienced makers with a hardened nozzle and an enclosed printer that reaches 300-350°C.
PPS is polyphenylene sulfide, a semi-crystalline, high performance polymer chosen for jobs where common engineering plastics soften or lose strength. Our PPS-CF filament reinforces it with carbon fibre for rigidity, strength and dimensional stability, and the fibre also reduces shrinkage so complex parts keep accurate geometry. It is designed for extreme thermal, chemical and mechanical environments, and it asks a lot of your printer in return.
These are the published settings for our 1.75mm PPS-CF Filament, sold on 1kg spools in Black.
| Setting | Value | Notes |
|---|---|---|
| Nozzle temperature | 300-350°C | 320°C recommended |
| Bed temperature | 90-110°C | 100°C recommended |
| Print speed | 60-200mm/s | 150mm/s recommended |
| Heat deflection temperature | 245°C | Top of our HDT ladder |
| Tensile strength | 95-105 MPa | From our product data |
| Drying | Not listed | Check the product page |
Keep the roll sealed until you need it, and check the product page for current drying guidance or contact us before your first print.
PPS-CF is the next step up from our two other high heat carbon fibre grades. Here is how the three compare on the figures in our data.
| Filament | HDT | Nozzle | Tensile strength |
|---|---|---|---|
| PET-CF | 205°C | 260-290°C | 75-85 MPa |
| PPA-CF | 220°C | 255-275°C | 108-112 MPa |
| PPS-CF | 245°C | 300-350°C | 95-105 MPa |
PPS-CF adds 25°C of heat deflection over PPA-CF and 40°C over PET-CF, but it is not the strongest on paper, since PPA-CF lists the higher tensile strength. The other two also print below 300°C. See where all three sit across the range in our heat deflection temperature chart.
PPS-CF is dispatched from our Perth and Melbourne warehouses as a 1kg roll. It counts towards volume pricing with any other 1kg rolls, so adding a roll each of PPA-CF and PET-CF for comparison prints makes three rolls and 5% off, with 10% off at six rolls and 15% at twelve. Businesses printing production parts can apply for a trade account.
Check four things: a hotend that reliably holds 300-350°C (320°C recommended), a bed that reaches 90-110°C, a hardened nozzle and an enclosed chamber that can safely run at the temperatures the material needs. If 320°C is beyond your hotend, PPA-CF at 255-275°C and PET-CF at 260-290°C still deliver HDTs of 220°C and 205°C, and both are covered on our PET and nylon pages.
Choose PPS-CF when temperature or chemical exposure is what limits the part, for example a bracket beside an engine or a fixture near a heated process. It lists a 245°C HDT against 220°C for PPA-CF. When the part mainly carries load, PPA-CF is often the better fit: it lists higher tensile strength, low creep and vibration resistance, and it prints at a far lower nozzle temperature.
It is not recommended for AMS or AMS Lite systems. The stiff carbon fibre reinforcement can increase wear on internal feeding parts and may not travel reliably through a long filament path. Load it directly from an external spool holder or a sealed dry box instead, which gives a shorter, more controlled path and keeps the filament dry during a long print.
Keep it dry. Store the roll in an airtight bag or container with fresh desiccant in a cool, dark place, and return it as soon as a print finishes. During long jobs, feeding from a sealed dry box protects it from humidity. Because our product data does not list a drying temperature, check the product page or contact us before drying a roll that has been left out.
