This question really is a hard one since we see Bender in soo many scenarios getting "born" so we have the "Bendless Love" EP were we see him getting born in his regularly size in Tijuanam Mexico, Fbrica Robotica De La Madre, so we know where he was born.
We got more proof that Bender's mother really is that machine as seen in Bendless Love, we got EP "Xmas Story" were we can see that Bender gets a card from his mother (the yellow arm robot that picks him together in EP Bendless Love).
In EP "Teenage Mutant Leela's Hurdles"
cheap louis vuitton handbags they all get youthasized and they get younger by the minute and we there sees Bender getting back too his baby state.
And in this EP "Lethal Inspection" we see Hermes Conrad as inspector 5 and baby Bender getting inspected by Hermes. They go to Mom's fabric in Mexico so we still now that he got born there.
And then there is also the EP "A Clockwork Origin" were Bender says that he is evolving and growing BUT Prof. Farnsworth says that robots got created quite recently. But later on in this EP we can see that
