As you see in every issue of SignCraft, CNC routing makes a wide variety of 3-D signage not only possible, but practical. The versatility of CNC’s cutting and routing capabilities makes it a very powerful tool in the hands of a creative designer.
Of course, a CNC router can handle plenty of routine production tasks—like cutting and drilling. But it also makes it easy to add layered outlines, background effects, panels and borders. It lets you create the type of graphics that draw the viewer’s eye.
In a world where viewers are bombarded with visual messages, this becomes a critical task: getting them to choose to look at and read your client’s message. Dimension can add a lot of interest and appeal to a message. It lends a feel of quality and permanence to the image of the business.
Take a look at how these sign makers are using CNC routers to create custom signage, combining a variety of materials and production techniques. You’ll see textured backgrounds, holes right through the sign face, applied convex letters, simple cutout layers and incised letters. There are graphics cut from PVC, HDU and ACM. And don’t overlook the example of how the results Bob Fiddler is getting when he prints directly on routed PVC signs using his flatbed printer.
We’d like to see how you are putting this equipment to work, too. Send your photos to firstname.lastname@example.org today.
