Inside the Tech for New Year 2026: How PA12 Powder Bed Fusion Creates Your Perfect Frames

Precision Manufacturing Built for You

As we step into 2026, technology-driven personalization is redefining how products are made—and how they fit into our lives. Eyewear is no exception.

iAyez frames aren't just different in concept; they're different in construction. Using PA12 nylon powder bed fusion (PBF) 3D printing, iAyez achieves levels of precision and customization that traditional injection molding simply cannot match.

The Numbers That Matter in 2026

Advanced manufacturing isn't about buzzwords—it's about measurable precision.

Here's what defines your frames:

• Layer thickness: 100–120 microns (about the width of a human hair), built layer by layer for smooth, accurate geometry
• Dimensional accuracy: ±0.3%, so your face scan translates directly into real-world fit
• Structural stenciling depth: 0.5 mm—visible, tactile, and strong
• Maximum build size: 675 × 366 × 545 mm, offering complete design freedom

These specifications ensure your eyewear is custom-built, not approximated.

Why PA12 Nylon Is Ideal for Eyewear

PA12 (Polyamide 12) is one of the most advanced polymers used in additive manufacturing—and it's perfectly suited for eyewear.

Key benefits of PA12:

• Flexible enough to absorb impact without snapping
• Rigid enough to hold optical lenses precisely
• Lightweight designs with minimum wall thicknesses of 0.8 mm (flexible) and 2 mm (rigid)
• Excellent dye absorption for rich, lasting colors
• Skin-safe, chemical-resistant, and dimensionally stable across temperatures

From Digital File to Finished Frames

Every iAyez order begins digitally and is manufactured only after you place it—no inventory, no overproduction.

The process:

1. Your custom design triggers a secure digital file transfer
2. PA12 powder spreads in ultra-thin layers across the build platform
3. Laser energy selectively fuses particles according to your frame geometry
4. Layers build up until your unique frames are complete

Key production parameters:

• Build chamber temperature: 168–172°C
• Cooling time: 12+ hours for dimensional stability
• Post-processing: bead blasting for finish, optional dyeing for color
• Quality control: dimensional verification against your scan

Every specification exists for a reason—0.5 mm engraving depth ensures your five-letter word is permanent, while ±0.3% accuracy ensures your frames fit as scanned.

Advanced Interlocking & Assembly Capabilities

PA12 powder bed fusion supports interlocking parts and enclosed assemblies, printed together and moving freely.

This enables:

• Integrated hinge designs
• Flexible elements without extra hardware
• Fewer parts and fewer failure points

Injection molding requires multiple components and assembly steps to achieve the same result. PBF does it in one build—stronger, simpler, and more reliable.

Experience the Future of Eyewear in 2026

Technology should work for you—not the other way around. With precision manufacturing, advanced materials, and on-demand production, iAyez delivers eyewear designed for how you live today.
