PETG Temperature

[jofleck 0]

Hey Together, 

 

I ordered a spool PETG filament from 3djake.com own brand. On the spool there is a recommended temperature of 195-220°C. On the website they recommend 230-250°C. The Cura default CPE setting (240°C) is working well. 

 

So printing too hot is not good due to toxic fumes etc. 

 

So what is the best temperature to print with PET-G Filament? Maybe someone tried 3DJake filament yet?

I have not tried this, but for the PETG (Matterhackers Pro PETG and Taulman T-Glas) I use the nylon presets to start with.

So the nylon presets are even hotter than the CPE settings. I tested to print the filament with 210°C and noticed that the layers are not sticking together. So the temperature label on the spool must be incorrect. 

 

Thanks ?

I will be posting a two color PETG print soon. I wioll have cleaned up the supports and such, but it should give you an idea.

And, yeah, I do not think 210 can really do PETG materials any justice to tell you the truth.

I thought I would pass along a bit of philosophy that I use when using one material for an unlisted material.

 

I go for a material that is slightly above rated temps for the unknown/unlisted material. This will always allow for the basic functions to work. Things like loading and moving, etc. Non printing oriented functions. There is nothing worse than a clog when it is not hot enough for a smooth flow during those ops.

 

Since you can set the print temps and other factors such as retractions an other things in Cura for actual printing, that is where I exercise control over printing functions.

 

So, I get to always have a smooth flow when performing filament ops because the temp will always melt the material and always get the actual printing settings I want within Cura.

I like PET and CPE+ my my PET stock are MadeSolid PET+ when I run it on my UM3, I started with CPE+ black (which I also like to print just the smell gets to me) and changed a few things. temp is at 250 but prints well on 245degC with bed of 80-85 degC enclosed. preferred off fans for functional parts but 1-10% fan for making it look pretty. Also print at a lower speed @250 degC dont go over 40mm/s (to start with see if starts to skip steps or clogs/nozzle. I would start with that but you need to experiment with the settings as I am not sure of 3DJakes' PETG composition. I think UM2 should be able to handle it nicely but always check the couple they wear out fast at this temps and higher.

 

Hope it helps.

Here's the thing. This is a person who has found success with his choice of filament. AND, it is a great starting point. But, remember, it is a starting point. Great starting point, but a starting point nonetheless.

 

So, if his settings do not work, it is not @jffry7's fault. He is passing on great info and should be looked at. I choose to be more general mainly because, well, I print weird stuff and what works for my strangeness, probably is not good for most 3D printing projects.

 

But, this is an excellent starting point. :)

Agreed with @kmanstudios, which is why I mentioned you need to experiment. Thats how you will get your expected result. Those settings have been my go to start settings for 3 different printer. Full disclosure, 2 of them where on the 1.75mm filament. Out of 3, 1 was direct drive so i think you should be covered. First few tries will get you there so dont be discourage, mistakes are ok as long as you learn from them.

Thanks guys ? Well, I think I have a lot to do the next weekend with playing around with my settings.

Do not think of it as a lot to do. Think of it as a lot of play time :)
