Waterabsorptionspectrum

UV-curable 3D-Printing resins, which means that they have a specified reactivity to light. This reactivity controls how the resins behave in the printer. Specific parameters about its reactivity are the Critical Energy (EC) and the Depth of Penetration (DP).

A UV light meter is a device that measures the intensity of ultraviolet (UV) light. Getting the current data on what UV intensity of your printer will help you adjust your printing settings better.

Absorptionspectrum

There may be dead pixels we can't see on the screens, but it causes some print fail, especially when you try a lot of different settings and still don't get a successful print.

Absorbance

We review the recent progress in the quantitative understanding of light absorption by colloidal semiconductor quantum dots within the framework of the Maxwell-Garnett (MG) effective medium theory. The fundamental quantities used to describe light absorption by dispersed absorbers—intrinsic absorption coefficient, molar absorption coefficient and absorption cross section—are introduced and it is shown that the MG model reduces to a local field correction in the case of strongly diluted dispersions. The correspondence between experimental results and this so-called local field approximation is first demonstrated using PbSe and PbS quantum dots as model systems and then extended to other materials. Moreover, it is shown that by adapting the local field corrections, the analysis can be extended to quantum rods and core/shell heterostructures. Finally, recent applications of these results are discussed and future research directions are indicated.

Because of the differences between UV light uniformity and screen transition rate, It is normal you get different data at different test points.

You can compare the different data between different accessories like FEP, nFEP, and screen protector films. different areas like the center and corners, then adjust the setting to get a similar print quality.

The light will decay based on long-term work; for a resin 3D print farm, it is necessary to test if your printers keep the best status. You may adjust PWM or use higher exposure time when decay happens.

Reactivity to light is measured by exposing the resins to different doses of energy (Exposure), in most cases, this is controlled by increasing the exposure time in the 3D printer.
