Dialing in Polypropylene

[Bryan Eckert]

So I can finally reliability print the PP filament I have. 

Set up a filament profile turning off cooling for the first 6 layers, then max 50% fan speed, no auxiliary fan. Bed temperature at 100, chamber at 60. Seems to work well.

60mm/sec outer wall speed, 100 everything else.

Benchy came out decent enough. Some wispy hairs but not much else.

Super interesting filament to print with. I want to try combining into PLA as a "bushing" in a toy arm /shoulder joint among a few other ideas.

Glad to see you finally got good success w/PP.

What do you think was the true turning point - like was parameters in your print profile do you feel had the biggest impact on making it work?

I do see a good bit of stringing. Ironic - since that was one of the Segments in the last episode of Andy's podcast!

Honestly, just the Magigoo PP and applying it liberally to the build plate and using a wide brim. The only difficult part printing it is pulling off the plate.

Do you let the plate fully cool down before trying to remove the part??

WooHoo I see the light! Never thought I would need to up the bed to 100C. That is a first for me. I used a draft shield but it wasn't really necessary. I used .4 mm layers with a .4 mm nozzle so it looks ruff. I have another one printing now at .2 mm layers, No Fan, 100C bed. Its 40 percent done and looking good and flat, except a little curl on the front of the hull. The previous print had a lot of curling on the front of the hull, I was sure it would knock it loose but it didn't.

Huge improvement in benchy looks with .2 layer. Looks like I should have added some cooling fan on the upper half!

I'm surprised it's working so well for you - considering you don't have an enclosure on your Prusa printer. 

Will admit - it's interesting that it looks like you need More cooling on the upper half. I think it's also a structural type issue - considering the pilar type structures of the cabin - yeah - it's like it doesn't have enough time between layers to cool down.

Looks good! I think I'm happy with my settings, the stringing I am getting is more wisps than anything.
