ESun ePA Naturel - Nylon 1.75mm 1Kg

Very tough stuff. Layer adhesion is incredible compared to PLA or PETG. Also tough to print due to bed adhesion (PEI textured build plate), but once dialed in it works well. I ended up using Elmers purple glue stick to keep it in place, and a first layer build temp of 275°C with a first layer bed temp of 90°C but it still lifted slightly at the edges. (Subsequent layers were at the recommended 265°/80°C) To be fair, this was a dense print with 10 walls and 8 layers top and bottom with 50% gyroid infill for strength (I was making a gear). I've ordered a garolite G10 print bed for further experiments. Hopefully that will resolve the bed adhesion issues. It may also benefit from a heated enclosure, but I don't have one of those. This may be my new go-to for functional parts that require strength. If I get this working satisfactorily, I'll try the carbon fiber infused version next.
