DLP3034-Q1: DLP-based 3D Printing Use Case

Part Number: DLP3034-Q1

Tool/software:

Hello E2E Experts,

Good day.

For my research project, I am working on DLP-based 3D printing that requires an independent 405 nm light source for curing photo-curable inks.
At present, I am using a single MEMS mirror chip to scan the laser. In this setup, the MEMS mirror signal must also control the laser on/off switching, which requires additional signal conversion circuits and careful frequency matching between the light source and the MEMS mirror. This makes the experimental setup more complicated and difficult to manage.To reduce the need for extra equipment, I am looking for a solution where the light source can operate independently of the MEMS mirror control signal, so that the two systems can function without interfering with each other.Could you let me know if TI has a product that meets these requirements, or if you can recommend a suitable option?

To explain further, I would like to use the DMD chip to generate light patterns by directly shining my own 405 nm light onto the DMD chip, and I do not want any connection between the light source and the DMD chip. Like in the image below.

Regards,

TICSC

    Hello, 

    The DLP3034-Q1 chipset is not designed to allow an independent light.  It was designed for in car applications showing real time video.  The issue with the independent light source, is that there interval of time (17us increments) that are aligned with the video pattern and DMD timing where the DMD mirrors are NOT controlled.  THis means light will scatter in any direction.  Thus, if you just pulse the laser without synchronizing the the patter to the DMD (Via RGB Enables signals from the DLPC120), then scatter light will occur.  If this limitation is acceptable, then it is possible.

    However, if this type of light scatter is not possible, then we would recommend using one of the chipsets and EVMs specifically designed for 3D printing.
