Very good, I'm really glad it went well.

For something like this, you would need a 5-axis printer that keeps the nozzle level but tilts the print bed away at an angle.

Thanks.. this worked much better.. The supports still separated from the overhang edge, but at least they didn't obstruct the print. They were more successful inside the hollow of the print as well. This was for a 12x18" activated charcoal filter to attach to a resin printer enclosure 4" duct vent.. unable to vent outside.

Try organic supports.

Hi have had multiple failures recently on my printer..

Printing a large item with overhangs. I added full supports and it turned into a big mess. I tried printing this on it's side first, and the PETG just started bowing and deforming at the ends, preventing the print from continuing.

Using Prusament PETG Galaxy Black

I used PRUSA slicer (File attached) with auto settings to create supports. The supports look like confined spaghetti and eventually killed the print.

The print looked ok until it failed.
