What is the cheapest moulding method for a plastic object with approximate dimensions 34" X 34" X 3" ?
 
What shape is it? How many are you making? What properties must the molded object have (i.e. what material)...

Vacuum forming springs to mind but may be unsuitable for several reasons depending on your real requirements.

Posting guidelines faq731-376 (probably not aimed specifically at you)
What is Engineering anyway: faq1088-1484
 
Forming wet sand by hand or with a plastic bucket. That is if you want to mould sand castles.
