PC eSUN ePC filament

@David Sparrow That seems to be the only thing that eSUN lacks. It is the same for all their filaments. I would contact William directly at admin@intservo.com

 

Very cool. Now all we need to do is support him, either direct purchases from the INTSERVO site, or help William and Jeff Bezos make more money buying through their Amazon store.

 

Sounds like regular polycarb to me
My tests with it were similar. It is a bit tricky to get printing correctly, but it is a very strong/hard material.

 

Did some more printing with Polycarbonate filament (eSUN ePC). Still had some warping even with a 5 mm wide brim. Super strong, won't twist or bend at all. much stiffer than the same model printed in Taulman Alloy910 and eSUN Natural PETG.

Printed at:

260°C Extrusion
100°C Bed
60 mm/s speed
0.100 layer height
4 perimeters
20% hexagon fill
0 bottom layers, 8 top layers​

This is a fan duct for another printer that goes around an E3Dv6 Volcano, so I wanted something that could withstand much higher temperatures than PETG. I need to reprint it and think I will try some thing about 10°C higher on both the bed and extrusion. It is not cloudy even though the flash makes it look more white than it really is.

Printed on my R1.

 

@Schlomo, you are not providing enough information to be helpful, was it a big or small model? how long was the print? what was the printing environment? Pictures or it didn't happen.

This particular print was about 3:45 and I do not have an enclosure. Ambient air temperature was about 20°C with no drafts on the print and the parts fan was off for all but the very last 10 layers where the filament bridges the duct opening.

 

I am printing at nearly double your speed with no issues, but I do run hotter than you by 10°C Your bed is hotter and I am going to increase my temp to what you have set. I understand why you printed with 40% infill, mine is a duct and with 4 perimeters even 20% infill made it so strong I can stand on the part. I am going to reprint it with 15% and 3 perimeters, it should also drop the weight down a gram or two and might shave off a few minutes of print time.

 

Nylon has a bit more elasticity than polycarbonate. The biggest advantage of ePC is its ability to withstand heat as well as strength. I am sure ePC would work for this. The only thing you will need to concern yourself with is warping, especially on bigger prints, but then you will have the same issue with nylon.

 

Depends on the type of nylon. Some might be too flexible. If overall strength is the point PC is the best answer.
Although, most nylons are pretty strong...
You have to evaluate the material you need based on how it will be used.

 

Since it is breaking at the threads, would it be possible to use a heat set thread insert instead of trying to model them in plastic? I am just asking since I have no frame of reference other than your written description.
