Features:

• Made from high-quality materials, this cutting mat withstands repeated use and protects your work surface with self-healing.
• 3mm thick 3-layer PVC construction: The core layer of the mat consists of white hard PVC material, resisting the toughest of cuts, very suitable for heavy-duty cutting.
• A3 size, 450 x 300 mm with Imprinted angles ranging from 10° to 80°.These angles are handy for creating geometric shapes, accurate folds, and intricate patterns.
• The anti-slip construction ensures the double-sided mat stays in place and does not slide around when cutting. Ideal for quilting, sewing, arts and crafts, and DIY projects.
• The pad can be used universally and can be used on both sides.
• Offer protection for work surfaces and preserve the sharpness of the blades.

Applications

• Electronics Prototyping: A safe, non-conductive surface for laying out PCBs, stripping wires, and organizing tiny screws.
• Enclosure Modification: Ideal base for drilling small pilot holes or scoring plastic project boxes with a craft knife.
• 3D Printing Cleanup: Provides a safe surface for removing support structures and trimming prints with a scalpel.
• Crafting & Scale Modeling: Perfect for precise paper, balsa wood, or vinyl cutting.

Package Includes:

• 1 x A3 Self-Healing Cutting Mat 3mm Pad 450 mm x 300 mm

Frequently Asked Questions (FAQs)

• What does "self-healing" actually mean on a cutting mat?
  The mat is made of compressible PVC layers. When a sharp blade makes a thin cut, the material's elasticity causes the sides of the cut to squeeze back together, creating a smooth surface again. It doesn't magically melt back together, but it prevents the blade from catching in old grooves.
• Is this mat safe to use for soldering electronics?
  No. The mat is made of PVC and will melt or scorch if exposed to soldering iron tips or hot solder blobs. You must place a heat-resistant silicone soldering mat on top of it for thermal work.
• Will this mat dull my craft knife blades?
  Actually, it preserves them. The soft surface absorbs the blade's edge rather than forcing it against a hard surface like glass or wood, extending the life of your scalpels and exacto knives.
• How thick is the mat, and will it bend easily?
  The mat is 3mm thick. It is flexible but has a rigid inner core to prevent it from folding. It should always be kept flat to maintain its shape.
• Are the measurements on the grid in inches or centimeters?
  The primary grid markings are in metric (centimeters/millimeters), which is standard for electronics and 3D printing design.
• Can I use a rotary cutter on this A3 mat?
  Yes, the self-healing surface is excellent for rotary cutters used in fabric cutting or heavy vinyl work.
• How do I clean the cutting mat if it gets dirty?
  Use a damp cloth with mild dish soap. Do not scrub aggressively with abrasive pads or use chemical solvents like rubbing alcohol or acetone, as they will remove the printed grid lines.
• Is the A3 size big enough for standard keyboard builds or PCB layouts?
  Yes, 450x300mm is wider than a standard full-size mechanical keyboard and provides ample room for laying out large ATX motherboards or multiple small PCBs alongside your tools.
• Can I cut completely through the mat?
  It is very difficult to cut through the 3mm thickness under normal hobby use. However, excessive, repeated pressure in the exact same spot with a heavy utility knife could eventually penetrate it.
• Does the mat have an anti-slip backing?
  Yes, the PVC material naturally grips standard wooden, glass, or laminate table tops, preventing the mat from sliding while you apply cutting pressure.
