CPE+ vs PC for functional prototypes

[JstWantoRide 2]

I have used PC in my UM3 for functional prototypes and it works very well.

 

I am now trying CPE+ and it too is working well also.

 

I am just wondering what the difference in strength is between the two materials. I have the data sheets and understand them, but can anyone tell me (from experience) which material is stronger?

 

Again, this is just because I am curious and can not find an answer about this anywhere. Both materials are working well for me so far and both break after too much abuse. The picture attached is a section view of part of a product that mounts a cell phone to handlebars.

PC is technically stronger than any form of co-polyester like CPE/+. Nylon has good strength and more give if that is needed. Co-polyesters tend to be more rigid.

Very, very late to the topic... but for this application, I'd use nylon anytime. Just be careful that your final dimensions fit, Nylon is somewhat prone to shrinkage - better print slow (~35mm/s for all speeds) and make some tests to determine if you need to use scaling or the horizontal expansion setting.
