What is your experience with printing PET?

What is your experience with printing PET? I’m currently doing a couple of prints using http://www.plastic2print.com/de/1-75mm-pet-filament-natural-0-50kg-532.html and i love it more and more.
The prints come out nicely without much effort, the surfaces are smooth, it’s incredibly strong and lightweight. Did you encounter any drawbacks?

What are you using as a build surface?

Simple mirror plate @70°C, it seems to stick by adhesion and very well at that.

I think i found something PET is bad at, bridges.

the only downside is cost - but that might change drastically in the coming months…

Bridges aren’t as bad as i first thought.

I’ll try with a different nozzle next time

I’ve been using it for as long as its been out there, its a great material but just don’t find any use for it. It is pretty much the same deal as PLA with a double, triple price tag. Otherwise nice to work with.

@Matej_Rozman what is the problem? I’m currently planning to make most of the parts of my next printer out of it.

@Bjorn_Marl no problems, prints really well, but its pretty brittle and although has higher tg than PLA its still fairly low. I use it ocasionally only for display models, for mechanical parts I prefer ABS and recently, ABS-PC became my favourite type of material, its just crazy strong and tg in 120 degree area. Perfect for printer parts. Highly recomend it if you have capabilities to print it with-requires higher extrusion and bed temps. You can get it at http://www.reprapworld.com at almost half the price of PET. Tipp: if you want to produce objects with high degree of clearness you should provide really agressive cooling :wink:

Thanks @Matej_Rozman , i will take a look at that.

It likes to buckle in the extruder (mostly 1.75mm) more than any other material I’ve tried other than TPE.

@Whosa_whatsis thankfully neither the Bulldog xl nor my moified wade have any problems in that regard

@Whosa_whatsis Do you have any tips for printing TPE? Im playing with some now and its giving me lots of trouble buckling. Im looking at modding a gregs extruder for support immediately after the gear. But any other advice you have would be awesome. This is 3mm stuff.

Go slow, use the high end of the temperature range, avoid over-extruding (because it increases back-pressure), and again, go slow.
