Hi all, longtime lurker, seldom poster

From research i can see everyone reccommends the score and snap method with 3mm plasticard however the project im working on requires ALOT of cutting.

I'm making a smaller version of my degree piece but in plasticard (this was laser cut 3mm MDF):

I've narrowed it down to this neat looking handheld jigsaw however i'm worried about the motor burning out like a Dremel (Proxxon Micromot SS 230/E Super Jigsaw):


Or a much larger conventional scroll saw (Record Power SS16V Scroll Saw 16-inch):


Has anyone had experience cutting plasticard in this way? Does it melt alot when cut at these speeds?

Appreciate any help
