What is the best filament for printing miniatures?

When printing tiny details, even small differences in filaments can make the difference between a perfect print and a failed one. Which filament is best?

Not all filament is created equal.

At the moment, the best filament for printing miniatures on my BambuLab A1 mini is

Sunlu PLA+ 2.0 – I use the grey colour

What Makes It Better?

I’m no chemical engineer so I can’t tell you what the makeup of the PLA+ 2.0 makes it work best for miniature printing.

However it *feels* less brittle than the other filaments I have tried. This could explain why I get a lot more successful prints with supports with the Sunlu – they have a little move ‘give’ during printing so are less prone to snapping.

Downsides

Unfortunately I am yet to find a perfect filament, and even the Sunlu PLA+ 2.0 has a compromise. Hopefully it’s just a settings issue that I will work out with more testing, but at the moment I am getting some very fine stringing with this filament. It’s more a fine ‘cobweb’ than strings – and it’s really easy to remove after the print has finished – but I’ll keep trying to see if I can fix it over time.

Settings

The best settings for your printer will need some experimenting to dial in perfectly, but to start with, on my Bambulab A1 Mini using the BambuStudio slicer – the best settings I’ve found so far are:

Start with the default Sunlu PLA+ 2.0 profile and adjust the following settings:

Initial Layer Temperature: 205c
Other Layer Temperature: 200c
Flow ratio: 0.98
