My hub is going to specialize in functional parts, and I wanted to know which filament I should print in for functional parts (think spool holder in a weed whacker). I’ve made that spool holder in ABS, and it breaks apart rather quickly, so I did some research on tougher materials. I’m thinking I either want to print in Hatchbox PETG or Taulman Nylon Bridge, but I’m not sure which is better suited for functional parts. Can anyone give me advice before I spend anything on materials?
They are very different materials. Nylon is almost indestructible material; it has very long elongation before breaking and good elastic properties. Is also resistant to temperatures up to 100 degrees. The difference/drawback compared to most FFF materials is the the Young modulus is about 40% smaller. So is less rigid than average plastic. PETG is not so tough but is more rigid than Nylon (similar than ABS). Temperature range is also not so high as Nylon to just about 70 aproximatelly. Nylon has also good frictional properties against other plastics and also together with Nylon. Regards
If you want to specialize in functional parts then you should try both. I specialize in functional parts and I offer over 30 materials. The properties clients are looking for in terms of “function” can be very diverse. There is no silver bullet.
