Can you clarify about using transfer film?
A cutter will cut think films on a release liner. This includes sign vinyl, heat transfer material, window tint, stencil materials and some others. I don't think transfer film in and of itself would alleviate the need for a vinyl cutter. If you are trying to make shirts there are many ways to do this such as with heat transfer film, screen printing, sublimation, direct-to-garment (DTG), etc. Some of these methods would use a vinyl cutter such as with heat transfer film and sometimes with sublimation (contour cutting out the image).
