ZiRO Silk Gold nightmare
Long story short:
I bought a model. I am color separating it and printing it with some modifications. For the most part I am having success.
For the gold parts, I am using this PLA I bought, and it's turning into a nightmare. I have a massive failure rate with it. I ran a temperature tower successfully and I like the color at around 200C.

When the PLA is purging, it is pooling at the nozzle rather than flow out... It does this at 200C or even the default 220C.
It doesn't want to stick, keeps binding, causing layer shifting or just not adhering. I've had one part fail on me SIX times, six different ways, and I just need it to pass so I can move on lol.
Has anyone used Ziro Silk PLA? Have a profile that works with it? (I am not good at the tuning)
Foaming filaments are always tricky as they throw away accuracy for volume, they mess with the extruder's internal pressure and there is no easy way to predict where the ooze will go.
Foaming filament of any type should be considered a technical challenge, foaming TPE has a place when the ability to vary the flexibility matters but it's semi-controlled expansion, thermal resistance and changes in strength and resilience mean that it's always going to be tricky to use and newbies should be made aware that it's going need a couple of years experience before attempting it.
Foaming PLA is often described as 'Silk' by cynical manufacturers which deceives newbies into thinking it's just a cosmetic change, it isn't, it should be regarded as a specialist, technically difficult material.
The first thing to try is printing slowly, very slowly.
Cheerio,
