How to cut styrofoam ball

Styrofoam is an excellent material for a variety of arts and crafts since it is lightweight and simple to paint. It’s simple to cut styrofoam into whatever form you desire, but you’ll need the correct equipment for the job. Manually cutting styrofoam using cookie cutters, knives, or box cutters is one option. Use a wire cutter or an electric knife for a smoother, more completed appearance. You’ll be cutting styrofoam into the shapes you need in no time, whether you’re constructing personalized parts for your cosplay costume, unique ornaments for your Christmas tree, or prop components for a theatrical show.

Cutting Styrofoam Manually

For straight cuts, use a blade.

1. For straight cuts, use a blade. Knives, box cutters, precision blades (such X-acto knives), and hacksaws are excellent for cutting through styrofoam, particularly if no curved cuts are required. Before cutting your styrofoam, run the blade along an old candle for a smoother cut.

  • Use a white candle to wax your blade to prevent getting colored candle wax on your foam.

To cut through styrofoam sheets, use dental floss

2. To cut through styrofoam sheets, use dental floss. Cutting straight lines through sheets of styrofoam using dental floss is a breeze. Place the styrofoam on the table and place the floss below it. Place one hand on the styrofoam sheet and line up the floss along the path you wish to cut through the styrofoam. Pull the end of the floss farthest from you towards you to slice the styrofoam.

Make interesting shapes using cookie cutters.

3. Make interesting shapes using cookie cutters. You could cut through styrofoam with a cookie cutter if you have a reasonably thin piece (no more than two inches or five cm thick). Simply push the cookie cutter’s thin edge on the styrofoam until it punches through to the other side. The resulting styrofoam object will be in the form of a cookie cutter.

4. Try cutting it while submerged in water. If you don’t want to cause a mess, consider cutting styrofoam underwater, which involves immersing a piece of material in a tub or bucket filled with water and cutting it with a knife underwater. This keeps the little fragments from flying all over the place and allows you to make a quicker, and hence smoother, cut. Before dumping out the water, remember to strain it. Because styrofoam does not absorb water, the sliced styrofoam block may be simply patted dry afterward.

Cutting Styrofoam with Electric Tools

To cut thicker styrofoam pieces, use an electric knife.

1. To cut thicker styrofoam pieces, use an electric knife. An electric knife is your best choice if you’re cutting through multiple pieces of styrofoam at once, or a single piece that’s several inches (several centimeters) thick. They’re excellent for straight cuts, although they might also aid in a gentle curved cut.

To cut through bigger pieces, use a foam cutting saw.

2. To cut through bigger pieces, use a foam cutting saw. Cutting through big blocks of styrofoam, such as those used to box TVs and other large appliances, requires the use of foam cutting saws. They are, however, the most costly alternative, with prices ranging from $150 to $400 USD.

  • In most cases, all you have to do is switch on the saw and push the piece of styrofoam you want to cut onto the blade while keeping your hands clean. Consult the manufacturer’s instructions for the saw you’re using.
  • Wear a dust mask and safety goggles while cutting styrofoam with a power saw. Power saws produce “foam dust,” which resembles sawdust but may irritate the lungs if breathed.

For flawless cuts, use a hot wire cutter

3. For flawless cuts, use a hot wire cutter. Hot wire cutters use a heated wire to cut through the foam, leaving a flawless edge. They’re particularly good at making rounded edges or forms out of styrofoam.

  • Using the hot wire cutter, apply gradual, continuous pressure along the desired cutting line. The wire will shatter if you move too quickly through the foam.
  • When using a hot wire cutter, exercise extra care since the wires are very hot and may cause serious burns.
  • Hot wire cutters are ideal since they generate the smoothest cuts and leave the fewest styrofoam fragments behind.

Making Various Cuts

Stick to the instructions for the project you’re working on

1. Stick to the instructions for the project you’re working on. When cutting styrofoam, you may want to start with curved cuts and then go on to straight cuts. Both are OK as long as you follow the project’s instructions.

  • If you’re working on a project of your own design and don’t have any instructions, you may start by making curved or straight cuts. Remember, this is your project, so break whatever restrictions you want!

When cutting with a blade, use lengthy, sawing movements.

2. When cutting with a blade, use lengthy, sawing movements. On avoid shattering or crushing the foam, apply consistent, uniform pressure to the knife throughout the cutting process. Long, sawing movements will reduce the quantity of foam crumbs produced as well.

Cut out indentations in the styrofoam’s core

3. Cut out indentations in the styrofoam’s core. Start in the middle if you wish to carve a depression in styrofoam. Draw a line around the region you want to remove, then choose a tool that will enable you to remove it while maintaining the depth and curvature you desire.

  • A knife is the ideal tool for removing a depression with vertical sides. Simply choose an appropriate long knife and cut along the line you’ve drawn.
  • In certain circumstances, a rounded sanding tool works better than a knife for making indentations.

Using a bladed tool, cut channels in the styrofoam.

4. Using a bladed tool, cut channels in the styrofoam. Cutting channels through styrofoam is best done with a long, serrated knife or an electric knife. Make a mark on your styrofoam for the length and depth of the channel, then punch your blade through the styrofoam to the depth you designated. Remove the component after it has become loose.

  • Cut channels into a piece of styrofoam or along the surface of a piece of styrofoam using this method.

Cut spherical styrofoam balls along the center to divide them

5. Cut spherical styrofoam balls along the center to divide them. By sketching a line along the equator of a spherical styrofoam ball with a pointed pencil, you can split it in two. The manufacturer has previously marked this line on several styrofoam balls. To bisect the ball, use a sharp blade, a hot wire cutter, or an electric knife.
