Hydraulic ram seal
Description
I'Ve Often Wondered If It Was Possible To Print Engine And Hydraulic Seals As They Are Normally So Expensive, And For Many People In Remote Areas, They Are Difficult To Get. When I Blew A Seal On A Machine Last Week, I Decided It Was Time To Give It A Try So I Got A Roll Of Tpu From Www.Blueprinted.Com.Au And Had A Go. I Am Really Pleased With The Way It Came Out. The Finish Is Not A Problem Because The Radial Rings Defining Each Layer Work In Our Favour Creating Many Lips To Seal On. This Seal Is A Rod Seal And The O Ring, (Which Is Not Meant To Be Round In Cross Section), Is Inserted Into The Groove Of The Main Seal With The Flat Facing Out. It Is 38 X 54 X 12Mm. I Installed The First Prototype And Ran The Ram At Full Bypass Pressure With No Sign Of Any Leakage. Only The Durability Has Yet To Be Proven. This Project Begs For Someone To Do A Customizer Version To Vary The Sizes Easily. At Least I Now Know That It'S Easily Achievable. 6 March, 2016. Put Another Couple Of Hours Run Time On The Machine Again Today. 3D Printed Seal Is Still Holding Up Well.
