PRINTING WITH PPS
PPS — Polyphenylene Sulfide for Chemically Aggressive Environments
ThermaX PPS requires industrial hardware capable of 390°C+ hot end temperature. Its rapid crystallization kinetics and high-temperature requirements demand careful process control. Follow this protocol for optimal crystallinity and part performance.
- Extruder Temp 365–390°C — all-metal hot end required
- Bed Temp 120–160°C
- Chamber Temp 50–90°C recommended — heated enclosure if available
- Nozzle All-metal — ≥0.4mm diameter
- Drying 110°C / 4 hr minimum before every print session
- ⚠ Crystallization Warning PPS crystallizes rapidly on cooling. Inadequate chamber temperature or cooling speed can cause warping or delamination. Use a heated enclosure if available and avoid drafts during printing.
THERMAL DATA
Tm 285°C. Semi-Crystalline Thermal Stability Above 200°C.
Four thermal milestones defining ThermaX™ PPS’s operating envelope — verified against 3DXTech ThermaX PPS Technical Data Sheet v3.
PPS is semi-crystalline — its Tm of 285°C, not Tg, defines the material’s structural upper limit. Parts retain dimensional stability and stiffness at temperatures far exceeding the 85°C Tg due to the crystalline phase.
Crystalline PPS parts maintain mechanical integrity at continuous use temperatures up to ~200°C — significantly higher than many amorphous polymers with similar or higher Tg values.
HDT at 0.45 MPa for printed PPS. Actual structural capability extends far beyond this value due to the crystalline phase retaining stiffness above Tg.
Required before every session. PPS has very low moisture absorption, but residual moisture at 365–390°C extrusion temps still produces defects. Dry before every session.
CHEMICAL RESISTANCE
Broadest Chemical Resistance of Any ThermaX Filament
ThermaX™ PPS’s semi-crystalline Polyphenylene Sulfide backbone delivers the broadest chemical resistance in the ThermaX catalog — completely insoluble in any known solvent under 200°C. Outstanding resistance to acids, bases, organic solvents, hydrocarbons, and process chemicals across the widest temperature range.
Consult TDS for complete chemical compatibility data. PPS is essentially insoluble in all known organic solvents at temperatures below 200°C.

WHERE IT WORKS
Where Chemical Inertness, Flame Resistance, and Heat Stability Converge
When PPS is the answer: environments with aggressive chemical exposure, elevated temps, or electrical isolation requirements where flame resistance is mandatory.
Automotive
Under-hood components, fuel system parts, sensors, and housings resistant to fuels, coolants, and brake fluids at 150°C+. PPS withstands sustained exposure to automotive process chemicals.
Chemical Processing
Pumps, valves, manifolds, impellers in aggressive solvent, acid, and base environments. PPS is insoluble in most process chemicals under 200°C — the widest resistance envelope in the ThermaX lineup.
Oil & Gas
Downhole and topside components, seals, connectors in hydrocarbon and brine environments at elevated temperatures. Excellent resistance to H₂S, crude, and drilling fluids.
Electronics
Flame-retardant (V-0 inherent), stable dielectric constant and dissipation factor over wide frequency and temperature range. Connectors, housings, bobbins — no additive flame packages needed.
Industrial Tooling
Jigs, fixtures, wear components requiring dimensional stability, chemical resistance, and moderate-to-high heat performance in production environments with solvent exposure.
Defense / Aerospace
Structural brackets and electrical housings where chemical agent resistance and inherent flame retardancy are required without additives. Low smoke evolution in fire scenarios.
MATERIAL CARE
Moisture Is the Enemy. A Proper Protocol Eliminates It.
PPS has very low moisture absorption compared to most engineering thermoplastics, but printing with undried filament at 365–390°C still produces defects. Dry at 110°C for 4 hours before every session.
Dry Before Every Session
110°C / 4 hr minimum. No exceptions — even a sealed spool that has been open for a few days benefits from a fresh drying cycle.
Print From the Dryer
For best results, print directly from a heated dry-box or dryer system. Ambient humidity will re-absorb into the filament during extended print runs.
Store Sealed With Desiccant
Return unused filament to an airtight bag or container with fresh desiccant immediately after printing. Long-term storage in original sealed packaging is acceptable.
Recognize Wet Filament Symptoms
Popping or crackling during extrusion, rough surface texture, reduced layer adhesion, and visible bubbling in the melt are signs of moisture contamination. Re-dry and restart.
HOW IT COMPARES
ThermaX™ PPS vs. Commonly Evaluated Alternatives
Buyers evaluating PPS typically compare against PEEK for maximum chemical resistance at extreme heat, PEI 9085 for a lower-cost high-temp alternative, and PSU for a lower-process-temperature sulfone material.

FREQUENTLY ASKED
ThermaX™ PPS — Buyer & Engineer Questions Answered
What is ThermaX PPS?
ThermaX PPS is 3DXTech’s Polyphenylene Sulfide (PPS) filament — a semi-crystalline high-performance thermoplastic completely insoluble in any known solvent under 200°C. It is inherently flame retardant (UL 94 V-0 with no additives), with a Tg of 85°C and a melting point (Tm) of 285°C. Continuous use up to ~200°C. Made in Grand Rapids, MI.
What temperatures does ThermaX PPS require?
Extruder: 365–390°C with an all-metal hot end. Bed: 120–160°C. Chamber: 50–90°C recommended — a heated enclosure helps prevent warping from rapid crystallization. Dry at 110°C for 4 hours before every print session.
Why is PPS the most chemically resistant FFF material?
PPS is completely insoluble in any known solvent under 200°C — a claim no other common FFF polymer can match. Its semi-crystalline structure creates a dense molecular packing that resists chemical penetration far more effectively than amorphous polymers. It resists strong acids, bases, hydrocarbons, ketones, esters, and chlorinated solvents across a broader temperature and concentration range than PEEK or PEI.
What does “semi-crystalline” mean for PPS?
Unlike amorphous polymers (PEI, PPSU, PES), PPS has both crystalline and amorphous regions. The Tg of 85°C marks onset of chain mobility in the amorphous phase, but the crystalline regions maintain stiffness, chemical resistance, and dimensional stability well above this temperature — giving continuous use of ~200°C despite a relatively low Tg. The true structural upper limit is the Tm of 285°C, where the crystalline phase melts.
Why is PPS used in electronics applications?
PPS is inherently UL 94 V-0 flame retardant — no additive packages needed — with stable dielectric constant and dissipation factor over a wide frequency and temperature range. Excellent resistance to cleaning solvents, wave solder flux, and process chemicals. Connectors, bobbins, and electrical housings in demanding thermal and chemical environments are natural applications.
What are the limitations of printing PPS?
PPS requires a 365–390°C all-metal hot end and rigid process discipline. Its rapid crystallization kinetics can cause warping or delamination if chamber temperature or cooling speed is uncontrolled. PPS is inherently brittle without fiber reinforcement — tensile elongation is under 2% — so it is not suitable for impact-critical applications. A very niche hardware requirement: most desktop printers cannot run it.
How does ThermaX PPS compare to Stratasys FDM PPS?
Both use PPS resin with the same core chemistry. Stratasys FDM PPS is platform-locked to Fortus systems. ThermaX PPS runs on any open-material machine capable of a 390°C hot end — same chemical resistance profile at a fraction of the system cost. No proprietary support material required.
Should I choose PPS or PEEK for a chemical-exposure application?
Choose PPS when maximum chemical resistance is the primary requirement — PPS is insoluble in virtually all solvents under 200°C and delivers broader chemical inertness than PEEK across most reagent families. Choose PEEK when biocompatibility (ISO 10993), maximum stiffness, or extreme temperature above 200°C continuous use is required. PEEK is generally a stronger, stiffer material; PPS delivers broader chemical inertness at a significantly lower price point.
