3D Printed Columns Improve Bike Seat Suspension
Sharon Farr’s bike seat on her older Raleigh Tess women’s mountain bike was uncomfortable during her frequent rough trail rides. Her light body weight did not provide enough impact to trigger the seat’s design for additional cushioning.
Sharon’s husband, Christer, created 2 custom columns to provide more suspension for the bike seat. He designed the columns using CAD, and then imported them into Cura slicing software where he was able to customize the correct combination of layers and inner fill.
Christer used an Airwolf 3D HDR, dual head printer, to print the columns. The best design used 4 outer and inner layers at 50% fill. Fewer outer layers and greater fill could have been utilized for more cushion.
The printed solution provided the exact cushioning needed on the bike seat. To purchase the 2 suspension columns would have been $7.50 each, while printing them only cost $3.00 apiece.
“I was able to create a custom ride that can be changed quickly to accommodate rough off road riding or asphalt trail riding.” – Christer SmithSHOP NINJAFLEX »
The original Thudbuster LT seat post uses 2 urethane cylinders stacked on top of each other inside of a hinged parallelogram, to provide suspension through the round tube.
