Reproducible irradiance of 405 nm photocuring modules on BIO X series bioprinters
Achieving consistent photocuring is essential for producing stable, reproducible bioprinted constructs, especially when working with light‑sensitive, cell‑laden bioinks.
This technical note provides standardized irradiance measurements for 405 nm photocuring modules across the BIO X series, enabling users to optimize curing efficiency, support cell‑friendly crosslinking conditions, and harmonize workflows across multiple printers.
What’s inside:
Reproducible Irradiance Benchmarks
Standardized irradiance measurements (25–100% intensity; 4–6 cm LED distance) across multiple BIO X and BIO X6 units, demonstrating predictable irradiance‑distance behavior and high consistency in photocuring performance.
Printer‑to‑Printer Performance Insights
The analysis shows that BIO X and BIO X6 printers deliver comparable irradiance trends, with the BIO X6 exhibiting modestly lower variability between units.
Practical Photocuring Insights
Guidance on selecting LED distance and intensity settings that reliably reach biologically relevant irradiance levels (~40 mW/cm²), helping users balance efficient crosslinking with cell‑friendly exposure conditions.
