Prusament PLA - Silver. What can I say, prints perfectly for PLA, really nice finish as well.
In the UK, I have tried Rigid.Ink black PETG, pretty good, with strong detailed parts, but you will need to play with the Slic3r settings a bit to get the best prints, but it is worth the time getting the settings right as this prints the best overhangs and bridges with good strength. Prints well at 0.2 and 0.15, but it is expensive.
Sunlu PETG - white, Not at all bad, a bit stringy and can vary a bit between reels (A bit more or less stringy), good price vs performance, prints well at 0.2.
Colorfab XT - Black This is a co-polyester, nearest product would be PETG. Produces some really strong prints, but not for the beginner as it shrinks some so causes curling, you will definitely need to adjust printing settings to get this to print successfully, and even then, overhangs just cant get them to print properly, but everything else is really good and strong. Expensive as it only comes on 750g rolls Prints well at 0.2, haven't quite got 0.15 settings right yet.
Sunlu PLA - Grey (Silver), can't fault it, prints well and good price, strings a bit more than Prusament but not too badly, Prints well at 0.2 and 0.15.
Technology Outlet PETG - Various colours, Prints well, not quite as good as Rigid.Ink, but damn close, it is a bit more translucent but leaves a nice glossy finish, strong parts, slightly more flexible than Rigid.Ink, can be troublesome with the filament sensor on the Mk3, and currently on Amazon, less than half the price of Rigid.Ink, If I could describe the difference it's like Rigid.Ink put more opaque filler into their filament. Prints at 0.2 and 0.15 but slightly worse than Rigid.Ink.
My current go to PETG filament is Technology Outlet since price vs performance can't be beaten, although I'm tending to print some printer parts with Rigid.Ink, there is very little in between the two except the price with one at £19.99 and the other at £42.95
Still waiting for Prusament PETG to be available on Amazon.co.uk
