Poplar Plywood
Overview
Poplar-core plywood for laser cutting. Pale color, fine grain face veneer, consistent density. Better than pine ply for laser work. See also: Poplar (solid) for laser engraving.
Properties
Pros
- Inexpensive and widely available
- Light color for good engraving contrast
- Easy to cut
- Good for prototyping and budget projects
- Soft and forgiving
Cons
- Soft — dents and scratches easily
- Can warp more than birch plywood
- Not as strong as birch plywood
- May have internal voids
- Resinous knots can cause flare-ups
Best For
- Boxes
- signs
- laser cut panels
- lightweight structural parts
Avoid For
- Outdoor use (delaminate)
- very precise cuts near voids
Laser Compatibility
Poplar plywood cuts and engraves well — check for voids in core. CO2: cut 3mm at 200mm/s 60W; engrave 400mm/s 35%. Diode: cut 3mm in 2-3 passes at 80%; engrave 500mm/s 85%. Air assist reduces char on cut edges. Verify no glue voids before cutting — they cause inconsistent penetration.
