Eryone PETG – Wait PETG? Not PLA!? Whats the difference? I’m glad you asked!
To Play with PETG not PLA
Eryone PETG is very similar to PLA; however, it has many more attractive properties. For example, PETG is more flexible than PLA or ABS and a little softer and less brittle! In fact, short of using Nylon 12, you would be hard-pressed to find a more versatile filament. Printing with little or no shrinking, its ideal for large prints.
You can print without an enclosure and odour or nasty fumes. PETG has a significant chemical and water resistance, so use outside is no issue but be warned if you’re using it on glass…it sticks well! The print finish is gorgeous! It usually prints with a subtle glossy finish rather than the dull finish of non-silk PLA. There are a lot more translucent offerings in PETG than PLA
I printed a part for myself that is designed to be permanently submerged in warm water at 40c. I was using PLA, but due to the glass temperature of PLA being around 55c, I was finding significant warping. Eryone PETG has solved this for me! As a result, with its glass temperature being 80c, without the need to print with ABS and having to deal with the nasty fumes and higher hotend temps associated with it, it’s worked great!
Eryone PETG which I bought from Amazon for £23.99, is packaged the same way that the PLA is. Cardboard box, vac sealed & a desiccant bag. Due to the fact this was my first time with PETG, I had a touch of slicer tuning to do. Taking advice from a friend who almost always prints in PETG, I adjusted my hotend temps, print speed and retractions under his guidance and risked.
My first print was a simple flat piece for fitting a new motherboard to one of my Ender 3’s for a later article. Amazed by this success, I printed the rest of the enclosure. I did realise I had left supports turned on, but these virtually fell off!
All Strung up
Stringing with PETG is virtually unavoidable. It can be minimised by proper slicer tuning. However, I was lucky that from the start, my stringing was minimal. Fine hairs at worst but I have seen some truly horrific examples online.
Strength and good looks
I’ve already commented on how good looking the Eryone PETG prints are. It’s hard to photograph in black as its so shiny.
Here I have printed a structural part. It is intended to be part of a battery adaptor for my power tools to allow a better brand of battery to be fitted. It has to be strong, so I decided to try PETG for it. Setting my slicer to 40% infill and four walls, I printed the first piece. I was not disappointed! Try as I might, I couldn’t get the thing to bend or break!
To sum up, Eryone PETG in my mind is very underutilised as a filament. It’s physical characteristics and strength make it ideal for prototyping things that may need to be ABS or Nylon 12. With its weather and chemical resistance, this makes it perfect for something that will be in constant contact with the elements or UV rays and the price is reasonable too.
Eryone PETG is also an attractive filament. I could happily use it to print items I needed to be good looking if I was gifting them. Overall, its a winning combination once you get the settings dialled in.
