Cutting Rubber Stamp Material on the Wolfpawn 4040 Pro
wolfpawnrubber stamplaser alternativecrafts
Rubber stamp material (soft photopolymer or carving rubber) can be cut on the Wolfpawn for custom stamps when you don't have a laser — or when you want deeper relief than a laser produces.
Material Options
| Material | Availability | Notes |
|---|---|---|
| Soft rubber carving block | Art/craft stores | Easiest to carve |
| Pink or gray vinyl carving sheet | Amazon | Very soft, good for CNC |
| Linoleum / lino block | Art stores | Firmer, cleaner edges |
| DIY rubber sheet (Shore 40–50A) | Industrial rubber suppliers | Custom thickness |
Avoid: tire rubber, silicone (gummy, clogs bits)

Design Approach
Stamps work by relief — raised areas pick up ink, recessed areas don't.
- Design your stamp design (text, logo)
- Mirror your design — stamps print in reverse
- Create a pocket toolpath that removes everything EXCEPT your design
- Leave design standing proud by 2–3 mm
Depth Strategy
- Outline cut: V-bit at 0.5–1 mm depth around design edges
- Background removal: ball nose pocket pass, 1.5–2 mm deep
- Fine detail: small V-bit (30° or 60°) for tight corners
Testing
Ink the stamp (stamp pad or brayer) and test on paper before finalizing. Common issues:
- Design too fine: Thin raised sections fold over — make elements bolder
- Background not deep enough: Ink transfer from recessed areas — go deeper
Mounting
Glue finished stamp to a wood block with contact cement or super glue for a proper handle.
