Printing in PETG
🕑 Added 2023-06-09 02:27:03 +0000 UTCFor those wanting to print in PETG, it can certainly be done.
This was on my Ender 3 Pro with a direct drive extruder. Printed on a smooth borosilicate print bed using Overture PETG filament and Layerneer bed weld.
Ultimaker Cura slicer using 0.20 standard quality settings with these adjustments:
Hot end temp: 235C
Bed temp: 100C
8 mm brim
20 mm/s initial layer
25 mm/s top/bottom and wall speed
35 mm/s infill
4 mm retraction
75 mm/s retraction speed
I like to print slow.
Working with PLA, I've always over-extruded the first layer for better adhesion. PETG doesn't seem to tolerate that very well. The extra material tends to break loose into strings or collect around the nozzle until it's left as a glob somewhere on the print. No bueno! By relying instead on other methods of improving adhesion (bed adhesive and higher bed temp to combat warping), I've been able to eliminate the stringing and get some really clean first layers.

what size rigid tube do you use?
Konjuring, Ink.
can you make one with built in lights and bluetooth speaker?!

The current uplift tube designs don't require an airline connector. They connect directly to the flexible tubing.

Does anyone know what size airline elbow connector would fit the uplift please?
