Hi, welcome to the forum!
I would say ABS has kind of dropped out of fashion for ants in the past few years as has quite nasty fumes and likes to warp - probably the most popular filaments at antweight are PLA-ST (super tough) for rigid bits and then TPU for wobbly bits! (external armour usually)
I’ve seen E-Sun PLA-ST & Overture Super PLA+ thrown about as go tos.
For TPU - Overture is a brand I use and see plenty of others use too, a filament dryer is recommended if you have it out of the vacuum sealed packet for more than a few days.
