I make a lot of dimensional signs and have noticed it getting harder and harder to sell this type at a highly profitable price because of all the competition now. Routers are cheaper and just like plotter cut vinyl, wide format printing, and every other facet of the trade, it's becoming a commodity market. Even when you have a superior design, customers today are always putting price before everything else. And the truth is, high end dimensional signs take more time to make and typically use more expensive materials. It's a double edge sword.
As Signmaniac says about the availability of machines doing this sort of dimensional work and more people becoming good at this part of the sign market. This type of signage will be easy to obtain for a small dollar amount. It will be where you could change out the look every year or maybe in the future, every month. I personally do not like the look, it has been use so much since the sandblasting redwood and then the foam so it has grown boring. Do not take that wrong, there is a high level of skill to making these stand out, but Signmaniac is starting to see the writing on the wall. Come on the guy puts out some fantastic stuff and he sees the frustration of business dealing with people looking for the best price.
Let's take designing logos, people like what is the fab at the moment, as putting a cute graphic icon and then some font next to it. or a fancy shape created with software and then throwing some fonts on top. There are literally hundreds of thousands of people throughout the world doing this sort of thing, and the numbers are growing. How do I plead, guilty, your Honor.
Signs are an art form, you cannot be afraid to try new things, get looked at with a concerning eye and take the abuse and hear, "that is not what I was thinking it would look like, something more like this that I found on the web". Most, and I use that term loosely, are followers, if everyone likes it, they like it.
So if you are artistic being and want to start doing something else, do not be like some of Signmaniac's customers and and be just concerned with the buck, do something that is new and put some hard work into it and it will be more rewarding. And maybe with luck, pay off, if that is what you are concerned with.
