Have been on a kick lately making that toktok fad coffee Dalgona(?)
tsp instant espresso/coffee tsp sugar tsp water
Whisk or use beverage frothing device to whip it into a foam then apply however you please.
I put it over milk hot or cold sometimes chocolate, or over ice and pour milk over the top (or milk alternative)
Its like an espresso latte without much effort and way less technology.
I do not 3D print, but i do have some basic knowledge of it? I am not a
lawyerprinter, YMMV.I have heard that some materials can be smoothed over using acetone vapour; what about wiping the finished print to smooth over open pores on the surface of a print?
Alternately, since it’s not a flexible material what about applying something like 3M never wet?
