Can the wood slats or MDF be purchased pre-cut ready to assemble? If available does this product go by another name? I have read the article detailing how to make this using carpentry equipment but I am interested in buying them pre slotted for assembly. Thanks in advance for your time.

Depending on how you want to assemble them, yes. Most home centers sell strips known as lath, usually in bundles of 50. The strips are usually about 1 1/2" wide, 1/4" or 5/16" thick, and 4' or 6' long.
Lath strips used to be used as the foundation for plaster walls: they were nailed to bare wall studs with spaces, and then the plaster was applied over them and pushed through them. As the plaster oozed through the spaces, it would droop on the far side and naturally form a sort of hook that secured the plaster to the wall. These days, of course, sheet rock is much more common, but you can still get the lath strips.
I don't know what project you have in mind, but lath strips could be assembled into lattice for fencing, a trellis, etc.
Strips in other sizes are also available, and go by different names depending on their size and customary use. Furring strips are nominally 1" thick (so really closer to 3/4") and 2", 3", or 4" wide. Moulding and casing are two names for strips that usually have fancy profiles but may be plain, and which come in a variety of styles.
