💡 Tips:
- • Use masking tape to reduce charring
- • Sand lightly before cutting
- • Consider grain direction
- • Test on scraps first
⚠️ Cautions:
- • Avoid pressure-treated lumber
- • Check for metal hardware
- • Some woods are oily (resin)
- • Hardwoods may char more
Popular Wood Materials:
plastic Materials

2 materials available
This category includes various specialized materials. Always research safety data and test on small samples before committing to larger projects.
Popular Paper Materials:
fabric Materials
2 materials available
Fabrics cut beautifully with lasers, creating sealed edges that don't fray. Natural fabrics generally cut better than synthetics. Always test on scraps as different blends behave differently.
✅ Best Fabrics:
- • Cotton
- • Linen
- • Silk
- • Felt (wool/synthetic)
💡 Applications:
- • Quilting patterns
- • Fashion accessories
- • Home decor
- • Appliqué work
⚠️ Watch For:
- • Synthetic blends may melt
- • Heavy fabrics need more power
- • Some dyes are flammable
- • Test edge sealing quality
Popular Fabric Materials:
metal Materials
2 materials available
Metal cutting requires high-powered lasers. Most hobby lasers can only engrave metals or cut very thin sheets. Reflective metals can damage your laser if not handled properly.
✅ Laser-Friendly:
- • Stainless steel (thin)
- • Mild steel
- • Titanium
- • Painted metals
💡 Best Uses:
- • Engraving (most lasers)
- • Thin sheet cutting
- • Marking/etching
- • Industrial parts
⚠️ Cautions:
- • Check laser compatibility
- • Avoid highly reflective metals
- • Use proper focus and speed
- • Consider fire hazards

natural Materials
1 materials available
This category includes various specialized materials. Always research safety data and test on small samples before committing to larger projects.
Popular Natural Materials:
Material Selection by Project Type
Prototyping
Recommended Materials:
Focus on cost-effective materials that cut quickly and allow for rapid iteration. Cardboard and thin acrylic are ideal for testing designs.
Production
Recommended Materials:
Choose durable materials with consistent properties. Consider cost per unit and material availability for scaling production.
Artistic
Recommended Materials:
Prioritize aesthetic qualities like grain patterns, colors, and textures. Natural materials often provide the most interesting visual results.
Functional Parts
Recommended Materials:
Select materials based on mechanical properties like strength, flexibility, and wear resistance. Engineering plastics often excel here.
Thickness Considerations
Thin (0.1-1mm)
Typical Materials:
- • Paper
- • Fabric
- • Thin acrylic
Pros: Fast cutting, fine details, low power requirements
Cons: Fragile, limited structural use, warping risk
Medium (1-6mm)
Typical Materials:
- • Acrylic
- • Wood
- • Leather
Pros: Versatile, good strength-to-weight, widely available
Cons: Moderate cutting time, may require multiple passes
Thick (6mm+)
Typical Materials:
- • Thick wood
- • Thick acrylic
Pros: Very strong, dimensional stability, professional look
Cons: Slow cutting, high power needs, may not cut through
💡 Thickness Selection Tips
Consider Your Laser:
- • Check maximum cutting thickness for your laser power
- • Thicker materials need slower speeds and more passes
- • Focus becomes more critical with thickness
- • Some materials have laser-specific thickness limits
Project Requirements:
- • Structural needs vs. cutting speed trade-offs
- • Detail level decreases with thickness
- • Assembly methods may dictate thickness
- • Budget impact of material thickness
Understanding Material Properties
🔪 Cutting Properties
Edge Quality
How clean and smooth the cut edge appears. Affects whether post-processing is needed.
Kerf Width
The width of material removed by the laser. Important for precision fits and tolerances.
Heat Affected Zone
Area around the cut that's affected by heat. Smaller is generally better for precision work.
✏️ Engraving Properties
Contrast
Difference between engraved and non-engraved areas. Higher contrast = more visible results.
Detail Capability
Smallest features that can be reliably engraved. Varies by material density and laser power.
Depth Control
How precisely you can control engraving depth. Important for multi-level engravings.
⚠️ Safety Properties to Consider
Toxic Fumes
Some materials release dangerous gases when heated. Always check safety data sheets.
- • PVC releases chlorine gas (deadly)
- • Some glues release formaldehyde
- • Chrome-tanned leather releases chromium
- • Unknown plastics = unknown risks
Fire Hazards
Material flammability affects both cutting safety and storage requirements.
- • Thin materials ignite faster
- • Oil-soaked materials are dangerous
- • Some foams are highly flammable
- • Dust accumulation increases risk
Ventilation Needs
Different materials require different levels of ventilation for safe operation.
- • Wood: Basic ventilation
- • MDF: Enhanced ventilation
- • Treated materials: Special handling
- • When in doubt, over-ventilate
Testing New Materials
🧪 Safe Testing Protocol
Before You Start:
- 1. Research thoroughly - Check manufacturer data sheets and online resources
