hi guy, im curious 1 things as im considering to order parts to be 3d printed.

how small an item 3d printing can print? can they print very thin item? like 1 mm thickness curve? and how strong will that be? and does it will be fragile? for example, that 1mm thickness curve things, if i bend it open a bit, will it break? or it will bend back or it will bend to where i bend it to @@?

hmm, icic, because im thinking to modify my earphone, to fit in other eartip. so the modification need to be very small, because i just add on to the earphone
