wood substitude

[asd]

I am new to the cnc sign routing and I have lots of questions for those of you with experience. what other materials can be use other than wood to make signs? how do they compare to wood, durability, flexibility and cost?

thanks in advance

High Density Urethane Foam Board is ideal for sandblasting, carving and routing. Unlike wood it's 100% waterproof so it won't rot, decay or decompose.

You also can't get rid of it....... it won't burn, rot or legally be put in a trash dump.

You can also use Corian. Corian as a substrate will cost more out of the gate but will last far longer than any other material you may consider. When you talk of a material that can last as long as Corian you are also talking about a happy customer. A little info on the Corain is that it is completely UV stable, nonporous and can handle any weather condition that is thrown its way.

Most of my stuff is multimedia. I work with a lot of solid PVC, acrylics, DiBond, cedar, HDU and aluminum. Many times all on the same project.

Depending on it's use MDF ( Medex ) can be routed. Edges need to be sealed well after .Careful with exterior use.

Extera is outdoor MDF. Cheap. Routs like mdf. Paints well with anythng after clear sealed with sanding sealer. I dropped a piece of unfinished scrap in a bucket of water for a week and it showed no signs of swelling.

We've had our CNC for about a year now and I would like to try Corian. Do you have any suggestions about how to find a distributor?

There are several brands of Solid Surface materials. Corian, Wilsonart and Formica which are the leading suppliers in the U.S. All are comparable to one another in quality, the difference is the variety of colors. In most cases, before you can purchase the material from a distributor, you need to get certified by the distributor. This usually involves on sight training, approximately 4 hours at the distributor, in some cases they will do it at your facility. Regardless of what you are doing with the materials, most of the time they require the certification for material warranty purposes.

We too have been making signs, inlayed coutertops and more with this material for years now. It is great to work and not that difficult to do. As stated by Inlaying Corian, it is more expensive upfront but worth it. The material comes in sheet sizes that are 30" or 36" in width by 144" in length, be carefull in handling.

To find a distributor for any one of these, try the following links.

Good luck.

Thanks for the links. Have you ever tried a product named Avonite? It appears to be similar to Corian.

[Gino]

Yes, but so far.... only interior signs.

Yes, I have. Interesting enough, the world of Solid Surface is somewhat of one big family. Wilsonart does not manufacture thier own, they purchase it from Avonite, who is actually Aristech Acrylics. There are a number of companies that purchase Solid Surface Material from Aristech and brand it as thier own. I personally perfer Formica brands to the others. Solid Surface material from Aristech, primarily the white colors, are soft and when cutting on the CNC with an "O-flute" straight bit, the "chip" has a tendency collect and melt together like that of a EPVC, and is difficult for a dust collection sytem to pull it away from the cutting surface. Formica brands don't do this. When cutting thier material, the cutting "chips" are pulled away easily by the dust collection system. Corian I cannot speak for, I have used it only once and used a saw only.

Hope this sheds some light.
