How to Cut Foam with Your Cricut

You finally found the perfect foam for your costume piece, loaded it onto your mat, hit "Go" — and your Cricut just scored the surface instead of cutting through it.

Cricut can cut foam really well, but only specific types, with the right blade and settings. Thin craft foam and EVA foam sheets under 3mm are your sweet spot. Anything thicker than that, and you'll need a different tool entirely.

Types of Foam Cricut Can Cut

Not all foam is created equal, and your Cricut is picky about this. Here's what actually works in the machine.

EVA Foam Sheets (Thin)

Thin EVA foam, usually 1mm to 2mm thick, is one of the best materials you can run through a Cricut. It cuts cleanly, holds its shape, and is widely available at craft stores. This is the go-to for cosplay accessories, ornaments, and decorative shapes.

Craft Foam / Fun Foam (2mm–3mm)

Standard craft foam sheets, sometimes called fun foam, sit in the 2mm to 3mm range. Cricut handles these well with the right settings and a fresh blade. They're cheap, come in tons of colors, and are perfect for holiday decor, 3D letters, and school projects.

Cricut Foamboard

Cricut sells its own foamboard specifically designed for the machine. It cuts accurately and pairs well with Design Space templates. If you want zero guesswork on settings, this is the easiest starting point for foam cutting on a Cricut.

If you're curious how foam fits into the broader material picture, the What Materials Can a Cricut Cut? The Full List guide breaks down everything the machine handles across fabric, paper, vinyl, and more.

What Foam to Avoid

Thick EVA foam over 3mm is where Cricut starts to struggle. The blade can't get through in a clean pass, and you end up with rough, torn edges or an incomplete cut — even with multiple passes.

Foam thicker than 6mm is really a job for a laser cutter or a hot knife. Those tools melt or vaporize the material cleanly. Cricut uses a drag blade, which isn't designed for that kind of resistance. Pushing it too hard can damage the blade, the mat, and your machine over time.

Also avoid memory foam, packing foam, and foam rubber. These materials compress under the blade instead of cutting, and they leave a sticky, gummy residue on your mat that's a nightmare to clean up.

Blade, Settings, and Mat for Foam

Which Blade to Use

The Deep Cut Blade is your best option for foam. It's longer than the Fine Point Blade and handles thicker, denser materials. If you're cutting thin 1mm craft foam, a Fine Point Blade can work, but for anything 2mm and up, go straight to the Deep Cut Blade. For a full breakdown of when to use each blade, Cricut Blade Types: Which One Do You Need? covers every option with clear recommendations.

Pressure and Speed Settings

In Design Space, search for "Craft Foam" or "EVA Foam" in the material list — don't just guess with a generic setting. Craft foam typically runs at a pressure of around 300–350 and a speed of 3–4. EVA foam may need slightly more pressure depending on brand and thickness. Always do a test cut first on a small scrap piece before committing your full sheet.

Which Mat to Use

Use a StrongGrip (purple) mat for foam. Foam doesn't naturally cling to regular mats, and it can shift mid-cut, which ruins your shape. The StrongGrip mat holds it firmly in place.

Multi-Pass Cutting for Thicker Foam

If you're working with 2mm to 3mm craft foam and your first pass doesn't cut all the way through, don't panic. Multi-pass cutting is a simple fix. In Design Space, you can increase the number of passes from 1 to 2 or even 3.

Don't move the mat between passes. Leave everything exactly where it is and let the machine run through the same cut lines again. If you lift the mat or shift the foam even slightly, your second pass won't line up and you'll get double-edged, blurry cuts.

Honestly, I'd rather set up two passes from the start with 3mm foam than try to recover from a partial cut. It saves a lot of frustration.

After cutting, peel the foam off the mat slowly from the back side. Pulling too fast can stretch thinner foam pieces, especially small detailed shapes.

Foam Project Ideas

Once you get your settings dialed in, foam opens up a whole category of projects that cardstock and vinyl just can't touch.

• Costumes and props: Cut armor pieces, badges, and decorative elements for Halloween costumes or theatrical props. Foam layers and glues easily.
• Cosplay accessories: Thin EVA foam is the standard material for cosplay builds. Cricut makes cutting consistent, repeated shapes fast and accurate.
• 3D letters and signs: Stack multiple layers of cut foam to create raised letters for nursery walls, party backdrops, or business signage.
• Holiday decor shapes: Snowflakes, pumpkins, stars, and ornament bases cut cleanly from craft foam and hold up better than paper.
• Foam stamps: Cut custom stamp shapes from firm craft foam and mount them on a wood block for DIY printing.

Finishing and Painting Cut Foam

Raw cut foam has a porous surface that soaks up paint unevenly. Before you paint, seal the foam with a thin layer of Plasti-Dip, Mod Podge, or a flexible gesso. Two thin coats beats one thick coat every time — thick coats crack when the foam bends.

For paint, use acrylic craft paint. It's flexible enough that it won't flake off, and it bonds well once the foam is sealed. Spray paint can work too, but test first — some solvent-based sprays melt EVA foam on contact.

To glue foam pieces together, contact cement or a low-temp glue gun both work well. High-temp glue guns can warp thin foam, so keep the temperature setting low. For clean, professional-looking seams, press and hold the pieces together for a full 30 seconds after applying contact cement.

If you're building out a bigger project workflow, Cuttabl is a handy tool for managing your Cricut SVG files and keeping your designs organized by project, especially once your foam builds start getting complicated.
