DLP991U: Could you provide the most up-to-date illumination power capacity table for the DLP991UUV?

Hello E2E Experts,

Good day.

I'm looking to purchase the DLP991U DMD for a 3D printing research application. I saw that the UV-specific DLP991UUV model has also recently become available, but the documentation for it says "contact TI" for power capacity limits at various wavelengths. Could you provide the most up-to-date illumination power capacity table for the DLP991UUV? 

Also, I would need to order the EVM for either the 991U or 991UUV, but I only see in-stock availability for the 991U EVM. Would it be possible to get an EVM-mounted 991UUV?

Lastly, to reach the full 12+kHz rate on either DMD, is it necessary to have the associated lightcrafter control module? Does that need to be the EVM version of the control module?

Regards

TICSC

    Good afternoon, 

    Thank you for your inquiry regarding the DLP991UUV DMD for your 3D printing application. I reached out to our systems engineer so I can acquire the illumination power capacity table for the DLP991UUV DMD. I will let you know what these values are as soon as they are provided from our systems engineer. 

    Regarding EVM availability, we currently have in-stock EVMs for the DLPLCR99EVM and DLPLCR99UVEVM. To place an order for the DLPLCR99UVEVM, you will have to submit a request form rather than directly purchasing the EVM from TI.com. Once the request is filled out and submitted, our team will receive the notification to prepare the EVM for shipment.  

    Lastly, to achieve the full 12+ kHz patten rate, you would need the associated LightCrafter controller EVM module (DLPLCRC964EVM). The DLPLCR99UVEVM will not work when paired with any other controller EVM, besides the DLPLCRC964EVM. The DLPLCRC964EVM is required for proper operation at high pattern rates.

    Good afternoon, 

    I just received an update from our System's Engineer, and unfortunately, we are not providing Illumination power specifications for the DLP991UUV DMD at this time. We are still undergoing lifetime testing and performance modeling and expect to release this data for the DLP991UUV in early June.

    To better support your application and ensure we provide the best guidance, can you please share addition details? 

    Specifically, can you elaborate on the following:

    • What application is the customer considering for the DLP991UUV DMD?
    • What UV wavelengths is the customer wanting to target on the DLP991UUV DMD?
    • What UV power levels are needed at those wavelengths to be successful in the customer application? 

    If you want to share the details of your application privately (rather than being on the public forum), please send a friend request.

    Regards, 

    Tristan Bottone

    Hello Tristan,

    Good day.

    We're looking at using the DMD for a rapid volumetric 3D printing research project based on Computed Axial Lithography. The UV wavelengths we'd be looking at are changing regularly, but are around 365 nm to 380 nm. We'd need to have a minimum power capacity of ~3.5 W/cm^2 at those wavelengths for it to work in our application.
    Any thoughts?
    Regards,
    TICSC

    Good afternoon, 

    Thank you for the information! I was out of the office yesterday, so I apologize for my delayed response.

    Do you know if the customer is operating only at 3.5 W/cm^2 for the specified wavelengths? Can you also please confirm whether the customer expects to reach a higher maximum power levels at those given wavelengths?  

    Thank you!

    Regards,
