Mastering the art of laser cutting NovAcryl can significantly enhance your signage production capabilities. NovAcryl, a popular photopolymer material used in ADA-compliant signage, requires specific techniques for optimal results. Let’s dive into the intricacies of laser cutting NovAcryl and explore the best practices for achieving clean, precise cuts.
Laser Cutting NovAcryl: Equipment and Settings
Many large photopolymer fabricators exclusively use lasers to cut their NovAcryl photopolymer, with Universal Laser systems from Scottsdale, AZ, being a popular choice. For a 50-watt Universal Laser, the following settings are recommended for laser cutting NovAcryl:
- Power: 100%
- Speed:
- 0.6% for PT-236
- 2.0% for PT-118
- 3.0% for PT-060
- PPI (Pulses Per Inch): 1,000
- These settings provide a starting point for laser cutting NovAcryl, but you may need to fine-tune them based on your specific laser system and material thickness.
Understanding NovAcryl's Composition for Laser Cutting
NovAcryl PT Series Photopolymer uses PETG (Polyethylene Terephthalate Glycol) as its base material, not acrylic as many assume. This distinction is crucial when laser cutting NovAcryl, as PETG behaves differently under laser treatment compared to acrylic. PETG is a thermoplastic polymer resin that requires specific laser cutting settings for optimal results.
Tips for Successful Laser Cutting of NovAcryl
- Material Thickness: When laser cutting NovAcryl, ensure that the minimum cut widths are no smaller than the material’s thickness. For instance, if you’re cutting 2mm PETG, avoid widths less than 2mm to prevent fragility.
- Spacing: PETG tends to heat up during cutting, which can cause melting. Leave ample space (at least 5mm) between components to prevent this issue.
- Edge Quality: NovAcryl laser cuts with a highly polished edge. To achieve this, use high-power, low-speed settings as recommended above.
- Cleaning: Ensure your laser’s lenses and mirrors are clean, as dirty optics can decrease power and affect cut quality.
- Air Assist: Proper air assist is recommended for more efficient cuts when laser cutting NovAcryl.
Advantages of Laser Cutting NovAcryl
Laser cutting NovAcryl offers several benefits:
- Precision: Achieve smooth cutting edges even in filigree contours with no reworking required.
- Efficiency: No tool wear or changeover is necessary.
- Versatility: Process NovAcryl with protective foil in place.
- Consistency: Enjoy a high degree of repeatability and consistent quality.
Mastering Laser Cutting Techniques for NovAcryl: A Guide to Precision ADA Signage
Laser cutting NovAcryl requires a nuanced approach due to its PETG base material. By understanding the material properties and using the appropriate laser settings, you can achieve excellent results in cutting and marking this durable, chemical-resistant material. As you gain experience in laser cutting NovAcryl, you’ll be able to produce high-quality, ADA-compliant signage with precision and efficiency.
Remember, while these guidelines provide a solid foundation for laser cutting NovAcryl, always test on scrap material first and adjust settings as needed for your specific laser system and project requirements.
