One of the coolest new features in the upcoming Dead Space 3 will be the enhanced weapon crafting system.

And apparently, it's not just limited to putting a few new pieces on an existing weapon; we'll actually be able to combine complete weapons. Yeah, so like, the Ripper fused with the Flamethrower or something. …holy sh**.

Maybe this walkthrough video will help you to understand. It's pretty sweet and it appears the possibilities are almost limitless, as we can build and modify to our heart's content. Experimentation oughta be fun; go for anything that you think will help you better cope with the wacky Necromorphs running amok. Of course, you'll still have to gather requisite materials before you can create your ultimate dream weapon… Gotta work for it!
