PETG Settings

Recommended Posts

Can someone help me with PETG setting in cura? The MAJOR problem...OOZING that cause opening in the print when it drop from the nozzle in the print.

One factor of accumulation on the nozzle is when it print the infill... the junction of the infill with the wall are peel-off...

I slow down the infill speed because it underextrude...but nothing change...

I try underextruding (material flow%) at 99% and it's a complete fail..

Just one observation, you shouldn't block the hotend fan (small fan behind you have block the airflow, the part in front of the tfm coupler with your fancap should be open), you are blocking the heatsink effect with your fancap, than can cut drastically the life span of the coupler.

Also, by allowing to have more heat onthat zone, filament can expand and make much more difficult for the feeder to keep up. That would explain why the underextrusion effect shows more on areas where your print needs retraction.

The silver part is the airflow deflector...

You suggest to remove it?

I don't know that fancap, or what's the advantage of having the right side blocked, but afaik, all that orange square should be left alone and open. I could be 100% wrong ofc. Radials fans can't actually compress much the air, and they 'slow down' when the output area is too small.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
