Had an email from hobbyking this morning advertising their new selection of premium filaments. They say it's manufactured by a leading filament specialist. It certainly looks pretty - lovely colours. Decided to pick up a couple roles of PETG. It'll be my first experience with PETG so won't know How good it is compared to other brands, but looking forward to trying it.

I had the same email and watched the video it looks like it could be nice stuff, I'm prob gonna give the petg a try to  ~~

Do you get your filament from HK ?

yep, well least I have been for the last few weeks.

Project sparkie is made from their Trans blue abs and black abs





various wireless chargers made from the clear stuff





trans blue on Pod racer v2




new orange sparkie canopy




trans green on my custom vape batt mod




and of course on my new printer




good stuff despite the shockingly cheap price, go's down smooth, consistent melt temp, good layer bonding, nice finish....even better when acetone vaped.

Hey guys. Had a couple of days printing with hobbyking's new petg. I've printed about 10 models and had some good and some bad experiences. This is the first time I've used anything other than pla so I don't know if my experiences with petg so far are normal.

I read up on petg and understand it's meant to be similar to pla: flexible but stronger, increased resistant to moisture and with a higher heat resistance. It requires similar extruder heat and bed temp and is only slightly harder to print.

Here's what I found using a tronxy x3a which prints pla beautifully:

Doesn't stick as well as pla to glass or aluminum bed and needs gluestick or hairspray to adhere properly.

Bed temp had to be increased by 10-15 degrees over hobbyking's standard pla to aid stickiness during printing and avoid prints splitting/cracking once the model was cold.

Seems to be softer and goopier compared to pla and leaks out the nozzle far more mid prints. I set retraction values higher, but it's a still a problem.

The goopy overrun is a slight issue as it gets picked up by the nozzle and pushed around the print.  This can be an issue when printing models with fine details.

It doesn't print fine details well compared to pla. Thin walls are often brittle when cold and I've had 3 models split when I removed them from the bed. Larger less intricate models print really nicely and the petg sure seems strong when cold.

So, so far, it seems slightly harder to print with, but it's not difficult as long as intricate models are avoided.

Good bit of feedback there mate, I've found that PETG needs to be at the higher end of the temperature scale and up the retraction by 1 to 1.5mm more on a bowden setup. I print onto PEI at 70c sticks like shit to a blanket.

May have to add a roll next HK order.

Thanks Hozza.  ~~

The petg is rated at 195-220 C. I've found it prints at 200 but the layers don't bond too well when printed below 210 to 215. Problem I have with the tronxy is there's no filament cooling fan, so the higher temps risk the print curling. I've only had one such issue so far though, and it was on an intricate little model with thin and curved 1.2mm deep walls, so that's never easy to print without a filament cooling fan anyway.

I upped the retraction settings (that work perfectly with pla) from 6.5mm and 25mm a second, to 10mm and 35mm second. It's still oozing badly. This is my first bowden printer and I read somewhere that retracting too much too fast was bad for bowdens. Do you think I should increase the numbers further though?

Cheers  :beer2:

Hozza

Not sure how pure that PETG is because I run ESUN @ 245°C and Taulman3D @ 240°C

I run my E3D Titan extruder with 600mm of bowden @ 50mm/s retraction speed, 5mm retraction and 1.2mm coasting

I would deff fit a print cooling fan so you can use a wider range of temps  :beer2:

Coasting - that's a new one! Cool, will have a play with that  :beer2:

I've wired the tronxy up ready for a filament cooling fan. Just so much other stuff to do first I've not got round to installing one yet.  ~~

3D printers. So many upgrades. So little time!  :waiting:  :laugh:

Since this thread exists (thanks), my limited experience tonight suggests the PETG HK Premier filament is pretty good.

On my Fabrikator II Mini I left all settings on supplied basics apart from raising the bed temp to 58C from 50C and the Extruder to 239C from 192C as used on PLA.

Printed well, good bed adhesion to the Fab's std PEI bed material, but separated well once bed cooled. Nice clean print with no stringing and no extruder dribble.

Very pleased.................... (pic will double expand)

Just printed 9 filament reel clips in the same Sky PETG, and have been wrenching and twisting one around trying to break it or cause it to split...................... and I can't. 

Printed straight to bed, adhesion was a little TOO good till they had been left to really cool down, so next time I will try a little less bed temp.  Or would more be correct, so the bed will shrink more on cooling....................  :shrug:
