This saddle design is according to the TBIS-004 which is a Taiwan bicycle saddle strength standard.Third-party testing confirms the saddle withstands:

• 200,000 cycles of 1000N bending pressure
• 1400N impact test
• 400N tensile test

Important

Make sure that you have removed the restriction on mixed printing of high and low temperature filaments.

Before you print,apply a thin coat of glue stick,and dry your filament.

This Multi-material Bike Saddle is printed using Bambu Lab H2D, leveraging its dual-nozzle system to combine high-performance PAHT-CF and soft TPU 95A HF to achieve both durability and cushioning comfort. This saddle is installed on a bike by a 7*7 chromium molybdenum steel Bike Saddle Rail and M4x10 BHCS Machine Screws. Bill of Materials and Assembly Guide can be found at the bottom of this page.

With updated beam-interlocking function in Bambu Studio, PAHT-CF and TPU are interlocked tightly layer by layer to create a secure bond, resolving the issue where filaments with significantly different properties cannot be bonded with glue.

TPU cushioning section employs updated Zig Zag sparse infill pattern in Bambu Studio, achieving a soft yet supportive cushion by optimizing sparse infill density.

For high-performance PAHT-CF part，we design according to the TBIS-004 which is a Taiwan bicycle saddle strength standard.Third-party testing confirms the saddle withstands:

• 200,000 cycles of 1000N bending pressure
• 1400N impact test
• 400N tensile test

As this saddle is downloadable and individual users can print it with their own choice of filament and printer, neither I nor MakerWorld can guarantee the safety of any individual saddle printed using this file. Printing or using this saddle is at your own personal risk. The testing is only applicable to saddles printed with the correct filaments and under perfect printing conditions. It serves as a reference for the safety of this design. This project merely demonstrates a design process that extends the capabilities of FFF printing.
