Customized Fit Instead of One-Size-Fits-All<\/strong> <\/strong><\/strong><\/h2>\n\n\n\n

With SLA 3D printing, we create nose pads that precisely match each individual\u2019s nose shape. A 3D scan of your face provides the necessary data, the printer produces the customized component \u2013 ready in just a few hours. This approach accommodates anatomical features that would otherwise cause pressure points or slipping with standard components. <\/p>\n\n\n\n

What Is SLA 3D Printing?<\/strong> <\/strong><\/h2>\n\n\n\n

SLA stands for stereolithography, one of the most precise 3D printing processes available today. Unlike FDM (Fused Deposition Modeling) printing, where molten plastic is applied layer by layer, SLA uses liquid resin that is cured by UV light. 

Here’s how it works:<\/strong> A UV laser or LCD screen exposes the liquid resin with pinpoint accuracy. Where the light hits the material, it hardens. Layer by layer, the desired component is built \u2013 achieving precision within a few micrometers.. We use Formlabs Tough 1500 \u2013 a special resin that is both flexible and robust. <\/p>\n\n\n\n

Why use SLA 3D Printing for Individual Eyewear Components?<\/strong><\/h3>\n\n\n\n

The technology offers three key advantages: speed, with finished parts ready in just a few hours; precision, achieving micrometer-level accuracy, and a smooth, skin-friendly surface \u2013 ideal for components that rest directly on the skin. 

SLA particularly demonstrates its strengths with small, delicate components such as nose pads or temple arms. The materials are flexible enough to adapt to each person\u2019s nose shape, yet robust enough for daily use in sports or at work. The smooth surface is skin-friendly and comfortable. <\/p>\n\n\n\n
