Feature

●Chitu Systems UV meter tool for resin 3D printers 405nm digital UV light meter,portable UV intensity meter for resin 3d printers, 405nm only
●[Get Light Strength and Uniformity] 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
●[Make Exposure Tests Easier] The resin curing time depends on the strength of the UV light source. Once you know how it relates between exposure time and light strength, you get the right direction to do the exposure test
●[Find Dead Pixel] 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
●[Printer Maintain] 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

Why we need it?

Make exposure tests easier.

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.

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),

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.

Get Light Strength and Uniformity

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.

Printer Maintain

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

Find Dead Pixel

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.

Suggestions:

  1. It requests a 5V voltage supply, the best way is to use the board USB port directly before you go to print.
  2. Keep away from resin. If resin leaks on the probe, clean it with isopropyl alcohol with cotton.
  3. Extreme temperatures above 70℃ and below -10℃ can impact measurements, use in the indoor environment only.

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