Thanks. I think I'm getting the hang of it. Slowing the print down helps a lot for tricky prints.

Here's my latest attempt. A tricky print as the curved top side must be printed bed down fully supported. Curved side was sanded; sadly, I don't think PETG sands any nicer than PLA.

What have you found to be the major differences between PET+ and PETG, as far as how they print, flexibility, or how they finish (sanding/painting)?

Had anyone had problems with top layer infill getting all messed up, and not laying down properly. Started printing with some petg using the settings floating around in this thread last night. Perimeters, base and infill all went down beautifully - but when it went to fill over the top of the infill - it all bunched up and was just a fuzzy mess. By the 3rd top layer, the nozzle messily flattened everything out, and that final layer adhered and went down flat, but its very obvious the earlier ones were horrible.

What might cause this ? I guess that the filament wasn't adhering to the infill (20% infill, so had gaps) properly, though not sure why.

Ok i know exactly what you are talking about but need some more info.

What is your infill ext width set to?

What % is your infill set to?

What does the infill look like before it starts capping it off with the first top layer? Is it broken at all?

What is the temp?

Infill ext width 100%
Infill 20% (w/ 15% outline overlap)
245C extrusion (on 70C bed, seemed to stick fine)
I didn't have the bed fan on, perhaps worth trying again with that on
The 20% Infill looked fine, from memory.

Set your infill width to 150%, outline overlap to 25%. Your infill will be spaced 50% farther apart so at 150% always have min infill of 35%. If the infill doesnt go down flawlessly then the top layers will never come out right. Not sure of your speeds but they should be no more than 4200 print speed and turn your solid infill layer speed to 70%. Try printing an test and let me know how it turns out

I ordered some from Amazon. In general though, I want stiffer parts most of the time - more like metal parts.

I started with 110C bed. That worked but took a looong time to warm up. Now I am at 90C, and the parts still stick. I never tried lower. This is with purple glue stick.

I have had great luck with PETG. I have printed many long prints - like 10-20 hour prints at up to 95% infill. I don't think I have had a failed print yet. I am pretty much always using it at 95% infill because if I didn't want a strong part I would probably be using PLA.

I use an E3D with a 0.4mm nozzle and print at 255. I started at 245 and it worked, but I figured I would get better bonding at the higher temp, and have not had stringing. I am using 0.2mm layers only, and 30-60 mm/sec. I also am doing 6 top and 6 bottom layers.

My fan is so powerful (I sought out a crazy powerful 24v one) that at 100% my nozzle cannot stay over 225C, so I have to run my fan at 60% for PETG. For PLA I run the fan at 100%. My fan at 60% though is probably more powerful than what most people have.

I am not a fan of translucent colors, but as far as they go, the PETG ones are attractive. I will get black as soon as they have it.

When are opaque colors due in from esun?

There is supposed to be a preorder in about 2 weeks. Not sure if that is still on schedule or not.
