eSUN Metal PLA Filament 1.75mm, Metallic Spray-Free 3D Printer Filament PLA, Dimensional Accuracy +/- 0.05mm, 1KG Spool (2.2 LBS) 3D Printing Filament for 3D Printers, Bronze

Bought this after I experienced the large amount of time it takes before all traces of ASA filament have gone from my hotend!I printed a load of fan shrouds and after printing I switched to a yellow PETG, it took maybe 5mm of printing on a 100mm by 50mm part before the ASA had purged and was not contaminating the print, I was really shocked how long it took!So I bought this nylon filament to make sure this didn’t happen again, it made a HUGE difference using this filament as I could ensure the hotend was free from any remaining ASA.It took 3 cold pulls with this filament before it came out clean, it’s a really easy process that this filament is made for, it took maybe 10 minutes to complete this but it meant that I was able to switch back to PETG and know there was no ASA left to contaminate the print.Works well and recommended if you are switching between filaments with drastically different print temps.

I was dubious whether this was going to actually do anything. I've had several issues with clogged nozzles and bits of old filament appearing in my prints.I started using this whenever going from a darker to lighter filament, like from black to white, so I don't get any black bits in a white print. The other main time I use it is when I change material, like from TPU to PLA, or ABS to PETG. It prevents bits getting in your print that can weaken them. It's more important when going from a high print temp filament like ABS/Nylon to a colder printing filament like PLA, which could clog your nozzle quite easily.What I really find satisfying about using it, is when you put a bit through your nozzle and pull it out, you often see all the crud that was sitting in your nozzle waiting to spoil your print. Win.

Suddenly started getting stringing and spotty prints, instead of a good straight extrusion getting thin wiggley extrusion curling back up onto the nozzle. Pushed 20 cm of this through at 230C and a couple ofhot pulls and back to normal. Used to clear partial clogs on 2 printers 1 printing PLA and the other TPU works for both.

Anyone that uses a 3D printer will be familiar with clogged nozzles.Running some of this through when changing filament really helps to get any small particles out of the system and makes it less likely to get clogs.Well worth the money, and can lengthen the life of your nozzles.

It was fairly cheap when I got it so wasn't expecting much going into it but it's actually a really good filament!

Easy to use. And cleans the hot end.

This filament has serious issues, it has problems with layer shift, bed adhesion and it can't even adhere to itself.I've tried everything, different print temps, flow rate calibration, filament dryer the full deal, it literally does not work. It might be okay for very small prints but if you're printing anything that needs any type of strength (you can break the prints with a small amount of pressure as the layers aren't really adhered together) I would not recommend this product.

Bought this as my regular filament has been out of stock for 2 weeks, its OK, not the best. No problems sticking to the bed a little stringy but that's probably my settings.Also it's a little lighter in colour than shown and quite shiny.
