PETG - it's a first for me !

Postby Rockman » Sun Sep 25, 2016 4:45 pm

Hello.
Thought I would share in hope it helps others.
Been printing PLA from the start. Decided to finally try a new plastic thanks to "JohnSays" :).

So far....I like this material. Feels nice has a little flex to it and not as stringy as I thought it would be.....going to be using it more often....

Here are my settings:
PETG from Filaments.ca
210 temp
60 print speed
60 bed temp
1.2 retract material amount.

Outside of the slight warping. My fault as I'm printing directly on blue tape with no hairspray. I broke the original glass bed removing the buildtak and waiting for delivery. In the mean time used an old picture frame glass 8x10 ...working fine :)

Thanks for your sharing!

We have tried nature PETG from filament.ca with 80C bed temperature. It stuck well.
Maybe you can try higher bed temperature.

I appreciate the suggestion and will try the higher bed temperature - thanks Vicki :)

Yeah, I use PETG from Filaments.ca all the time, Printed at least 8 rolls of the stuff now. Mostly black. I get better results with 80c bed, I also print at 225 temp for black and around 215 for transparent petg.

That low. Been trying ESun PETG, It lifted from the buildtak quite bad at 70* I print it at 245. ( My FFCP loves it )

Thanks for sharing!

The filaments.ca PLA is my go-to for regular workaday prints, and it was thanks to someone else sharing their results and settings here that I was able to get going with it easily. I hadn't really wanted to mess with other filaments yet, but with the info here I might try out a PETG roll!

Biggest problem with PETG is that it doesnt like to stick to the buildplate. You may have to adjust the bed level with the thumbscrew. I just use some glue stick on the buildtak or glass side for a better stick.

Also, you should keep the printers doors closed for PETG (unlike PLA). This makes a huge difference!

I recently tried some PET that a friend of mine made for me. (25 pounds of it). And I have to say I believe I'm giving up ABS. I've consistently printed 10inch by 10inch parts with "0" warp and no raft. I love the stuff. I don't use buildtak though. Instead I use a PEI sheet that I got from Petermake3d.

Long story short PETG is my favorite now I run at 235 degrees and build plate is 75 degrees (PEI) 0 warp excellent layer adhesion, 0 raft, (think I could probably get by with 220 degrees just worried about layer adhesion. (any thoughts on that)

My only issue now is that my friend's medical tubing company moved, so I will have to do like everyone else now and have to pay for it. But the good side is at 25pounds it will be a while before I need to purchase it.

I keep the doors closed but top off for both PETG and PLA ... why wouldnt you keep them closed for PLA?

I print my eSun petg (black, orange, purple, white, blue) at 235 with the glass/hairspray at 88. I was at 90, slowly dropping it down. I cant get it to stick at 70, i've tried. However, the thought of printing PETG at 210 or 220 is sorcery.

When I bought MakerGeeks filaments, they told me because their blends are "pure", they require hotter temps to print well. I printed their Glow in the dark PETG at 260 and it came out NICE! However, it doesnt glow much :)

With PETG I experienced warping and lift off from the bed if I didn't close the printer.
For PLA it's normally good to have a good object cooling as it has a low glass temperature. It may depend from your bed temperature, your print object and so on, but it should also work if you at least leave the top opened.

I did find putting the fan cover over the left fan helped.
