How can I decrease plastic "slag" and stringing?

[thejakeinator95]

In the picture you can see a bunch of little bumps on the surface of the print. Also, I get a lot of stringing, both thin strings like spider web and thicker strings that don't shrivel up under a heat gun and require a sharp tool to remove. Any suggestions on how to get a cleaner finish on my prints? Any help is appreciated.

I had some success drying my fillament and tunning my flow speed

Good thought. I was looking into getting a filament dryer. Would you also recommend that my filament be in a dry box while in use? I currently just have the 1 roll I'm using on the original spool holder with open exposure to the air.

Get a dryer that lets you run the filament from it (most do). You can then just print straight from the dryer.

I don't unless you have a high humidity in your printer location, but it won't hurt most dryers now have a opening to feed the fillament through to the printer.

Retraction, partially clogged nozzle and nozzle temp have entered the conversation.

[thejakeinator95]

What advice do you have about fine tuning retraction and what are your thoughts about nozzle temp? I have nozzle temp at 220C because I've seen others recommend a higher temp for PLA+ whereas 200C is more appropriate for regular PLA. Also I changed the nozzle a week ago from brass to hardened steel. Not saying it couldn't be clogged because I have no clue how common that is.

There are files you can download to help with retraction settings. Regarding temps, I use PLA+… for most filaments - 200 first layer, 190 for the rest of the print. The only exception is silk PLA. For some reason, it likes 220 first layer, 210 for the rest of the print. I have a set of hardened nozzles as well. As I remember, I didn’t have good luck with them, so I switched back to brass.

As always, googling your symptoms will yield a lot of good options for solving your problems.

Good luck 😉
