CNC Plasma Art and Metal Sign Making

Cut welcome signs, wall art, fire pits, and custom gifts from steel with a CrossFire CNC plasma table. Start with free, ready-to-cut designs on FireShare, then finish your pieces with a durable powder coat.

Turn Steel Into Art

A CNC plasma table cuts the detailed shapes that take hours with a grinder: lettering, silhouettes, trees, and logos. Load a design, clamp a sheet, and cut it in minutes.

Many CrossFire owners sell signs and art online, at craft fairs, and to local businesses. Browse ready-to-cut designs on FireShare to get started.

Detail vs. Thickness

Thinner steel holds finer detail. Thicker steel lasts longer outdoors. Pick the thickness that fits where the piece will hang.

16 to 14 Gauge: Fine Detail

Best for indoor wall art, ornaments, and intricate lettering. It's light, cuts fast, and shows the most detail.

11 Gauge to 3/16": Outdoor Signs

The sweet spot for welcome signs, address plaques, and yard art. Stiff enough to hang outside without bending.

1/4" and Up: Heavy Pieces

Use it for fire pits, freestanding sculptures, and signs that need to survive weather and wear for years.

Keep Details Big Enough

A good rule of thumb: keep holes and thin bridges at least as wide as the material is thick. Smaller details can melt away or warp.

Use a Fine-Cut Nozzle

For thin sheet, a fine-cut nozzle or Hypertherm SYNC FineCut cartridge gives a narrower kerf and sharper detail.

Need Even Finer Detail?

A fiber laser cuts smaller holes and cleaner edges than plasma, with little or no cleanup.

From Design to Finished Sign

Here's how most makers go from an idea to a piece that's ready to hang.

1. Find or Draw a Design

Download a design from FireShare, or draw your own in a vector program and export it as a DXF or SVG file.

Browse FireShare →

2. Create the Toolpath

Turn your design into cut paths in CAM software, with lead-ins placed on scrap areas so they don't mark the finished piece.

3. Cut It

Load the file in FireControl, clamp your sheet, and cut. Run a test piece on scrap to dial in speed and amperage.

4. Clean It Up

Knock off dross, deburr the edges, and sand or blast the surface so the finish sticks.

5. Finish It

Powder coat for a tough, colorful finish that lasts outdoors, or use a patina or clear coat for a natural look.

6. Hang or Install It

Add standoffs, keyhole slots, or stakes so the piece mounts cleanly on a wall, post, or lawn.

Sell Your Metal Art

Many CrossFire owners pay off their machine by selling signs and art. These tips help you get started.

Start With Custom Orders

Personalized family name, address, and ranch signs sell for more than stock designs, and every order is a referral.

Price for Your Time and Finish

Count steel, consumables, powder, and your hours. Powder-coated outdoor signs usually earn more than raw steel.

Sell Online and Locally

Online marketplaces, craft fairs, farmers markets, and local businesses are all proven channels for metal signs.

Check Each Design's License

Free FireShare designs are a great start. Check the license on each file, or draw your own designs to sell.

Metal Art and Signs FAQ

What is the best CNC plasma table for metal art?

For most signs and wall art, a CrossFire is the best place to start. It cuts 2' x 2', runs on a standard 120V outlet, and starts at $1,995. For bigger pieces, the CrossFire XL cuts 2' x 3' and the CrossFire PRO cuts 4' x 3'.

What thickness of steel is best for metal signs?

Use 16 to 14 gauge for detailed indoor art, 11 gauge to 3/16" for outdoor signs, and 1/4" or thicker for fire pits and freestanding pieces.

How small can details be on plasma cut art?

A good rule of thumb is to keep holes and thin bridges at least as wide as the material is thick. A fine-cut nozzle helps on thin sheet, and a fiber laser holds much finer detail.

Where can I get designs for plasma cut art?

FireShare has a large library of free, ready-to-cut designs, including signs, flags, fire pits, and wildlife. You can also draw your own designs and export them as DXF or SVG files.

Can I sell metal art I make on a CrossFire?

Yes. Many owners sell signs and art online and at local markets. If you use a design from FireShare or anywhere else, check its license before you sell it.

How do I finish metal signs for outdoor use?

Powder coating gives the toughest, longest-lasting finish for outdoor signs. Clean and blast or sand the steel first, then coat and cure it in an oven like the Vulcan 16.
