Why Choose Our Precision Industrial PPS-CF 3D Printing?















Our engineering polymers deliver superior performance in demanding applications. With excellent chemical and temperature resistance, HeKeytech PPS-CF process enables you to replace expensive metal components while reducing weight and cutting production costs.






Key specifications:





    

  • Ultrapolymer temperature resistance. 

      

    • HDTA ISO 75 1.8 MPa 235 °C
      • 




    • HDTB ISO 75 0.45 MPa 264 °C
      • 

    

    • 




  • Chemically resistant against oils, solvents, and aggressive chemicals.
    • 




  • Flame Retardant: UL-94 V-0
    • 




  • Ultra-High stiffness.
    • 




  • Cheaper and more accurate to print than other ultrapolymers like PEEK or PEI.

      

    • Precision manufacturing with tolerances tighter than other FDM-service providers. Often as tight as ±0.1mm, normally ±0.2mm.
      •

Every print is optimized for quality and strength by HeKeyTech customized print parameters and management.

If our parts don’t meet the promises, or we’ll remake them FREE.














Skip weeks of traditional manufacturing delays. Upload your CAD files today, get instant automatic quote, and receive functional prototypes or production parts within a few days. Our streamlined workflow eliminates tooling costs, minimum order quantities, and long lead times – perfect for urgent projects, design iterations, or small-batch production runs.

Normal delivery to Finland: 4-5 days.
Normal delivery to Europe: 7-9 days.









Reduce Costs Significantly: Eliminate expensive tooling, reduce material waste, and cut labor costs compared to traditional machining or injection molding for low-volume production.





Accelerate Time-to-Market: Launch products faster with rapid prototyping and on-demand manufacturing. Make design changes in days, not weeks or months.





Enable Complex Geometries: Create lightweight, hollow structures and integrated assemblies impossible with traditional methods. Reduce part count and simplify assembly.





Minimize Inventory Costs: Print parts on-demand instead of maintaining expensive stock.





Sustainable Manufacturing: Use only the material you need, reducing waste drastically compared to subtractive manufacturing methods.


































PPS-CF Validation – Surviving the Extreme Conditions of a Race Engine









An internal oil-control component inside a race engine clutch housing / oil sump, designed to prevent oil sloshing and eliminate oil starvation under extreme cornering.

Developed for the Formula Student Oulu race car and operated throughout a full European summer competition season.









    

  • Continuous high engine temperatures through the racing season.
    • 




  • Severe vibration.
    • 




  • Constant exposure to circulating engine oil.
    • 




  • Fuel mist and aggressive chemical environment.
    • 




  • Prolonged race conditions across multiple events.
    • 










Detailed inspection after the season confirmed zero observable change in form or function. 





The component retained full geometry and function after sustained exposure to real racing conditions.

If PPS-CF maintains stability inside a high-performance race engine, it provides a reliable solution for demanding industrial environments requiring:





    

  • Thermal resistance
    • 




  • Chemical stability
    • 




  • Dimensional accuracy
    • 




  • Long-term mechanical integrity
    •
