Review on 🌞 SUNLU 3D Printing Filament: Precision and Quality in Additive Manufacturing Supplies by Tom Motko

Revainrating 2 out of 5

After trial and error it worked

I once successfully printed a flat sheet and then it failed on the 10th layer with a hardened 6mm nozzle but after that it clogged. I'm new to 3D printing so it might have been user error but I've tried all the temperatures, realigned my bed, changed bed types, used glue, used hairspray, it stuck and the first layer was nice and then became it's a mess. 10 layers inside. It looked so good until it broke. I would really like to get this working. I use an Ender 3 that worked with a 6mm hardened nozzle, couldn't even get it to stick to a leaf with a 4mm hardened nozzle, it clogged instantly. I use Marlin 2 bugfix, mesh layer alignment etc. I've tried every temperature in the area on the nozzle and bed and it clogs no matter what I do. I can't get it to be consistent. I printed 10 models perfectly with another PLA, by the way, even with some fancy materials that are a bit more complex and have glow-in-the-dark spots. This is actually the first time I've been able to print something unsuccessfully. I completely replaced the nozzle 4 times, went through the whole bowden tube order, now I need to buy more, everything on the hot end side and also replaced the gearing on the extruder, nothing stopped it from clogging. It worked best with 6mm, I'm wondering if I should get an 8mm nozzle for it to work properly. Does anyone else have this problem? --------- Update- ------ Photos of the current print included, this is a test print, it is already climbing the left front edge to finish or at least get to the point where he turns into spaghetti. I'll upload more photos once it's finished or fails. It usually clogs in the next two coats for reasons I still don't understand. - Update again --- So now it works, took almost the whole spool to figure it out. but it needs to be better cooled at the hot end of the ender 3, PTFE cooler, it needs to be printed at a much hotter level, so there is thermal creep that softens the filament in the bowden tube, causing it to expand and shrink Constipation leads after work. for >30 min. So I entered a custom fan setting using the fans I already have (server fans. Not recommended unless you know how to lower the voltage so they don't freeze everything, they are powerful) and i can change the fan speed, which helps with different types of filaments. And now this thread prints like a charm. Make sure you use a raft with this stuff and my temps are 230 hotend and 80 bed.

Pros
  • practical thing
Cons
  • so far so good
