DLPLCR4500EVM: Can not find the cad file in the 3d cad file of the EVM

Part Number: DLPLCR4500EVM


(There is a relevant previous question :,

but it does not solve my question and the previous one is locked. So asking it again)

We have recently purchased another EVM which is DLPLCR4500EVM). We have started testing it.

When I checked the mechanical cad file by checking the website (, I couldn't file the relevant mechanical design files.

I have checked each of the attached files in the website, but none of them contains the STL files.

In comparison, for example, when we had previously purchased 230NP, we could find the mechanical design file in the archive TIDM757.ZIP.


There are STL files in the archive.

In conclusion, I think the mechanical design files (STL) are missing. We need the mechanical design file so that we can design the whole system, by inserting the EVM and making it fit in the system.

Where can I find the STL files?

Thank you

  • Hello Kim,

    Welcome to DLP forum and hank  you for your interest in DLP technology.

    This EVM is designed and developed by a third-party.  I need to check with them if 3D mode for the complete EVM is available? It will take some time to get back with information.



  • Hello Vivek Thakur,

    Thank you for the answer.

    Honestly, we didn't reckon that it's the third party product, as the EVM's officially titled as "The DLP® LightCrafter 4500 development module"

    (e.g. not WinTech4500 or something)

    We believed that we had purchased the official TI EVM as we had been satisfied with another EVM from the TI.

    If it was from the third party, we would have considered more factors(e.g. technical support), before deciding to purchase (or not).

    Anyway, I think those files might be missing due to some mistakes—I understand : it might take a couple more days.

    I don't want to believe that the third party would not provide the files, for example, to protect their intellectual properties.

    (I believe the mechanical design files are essential parts when making a prototype system with the EVM.

    But if the files are not available, how can we design the system with this EVM if the mechanical design files are not available?

    Can the TI officially "request" the 3rd party to provide the mechanical file?)

    By the way, it's a little bit surprising that the design files are not available yet in the relevant section, as the EVM was first launched years ago.

    Thank you for your support again and we will happily wait more days

  • Hello Kim.

    We are looking into your requests. Please expect some delay in response due to the ThanksGiving Holidays. 



  • Hi,

    Thank you for all your support.

    Currently, we are waiting for the response, as this is essential.

    Isn't there any news about this subject?

    Thank you

  • Hello Kim,

    This EVM is sold by TI as TI product . It was turnkey designed and manufactured by a third-party. It has been redesigned to accommodate for change in optical engine and LED. 

    I am trying to reach out to appropriate person in the manufacturer. Unfortunately, response is slow and it is taking time.

    Thank you for your patience.



  • Hello Kim,

    Thank you for your patience. I am still waiting on response from the manufacturer.



  • Hi Vivek Thakur,

    Thank you for your support.

    Although TI's general support is amazing, the current situation is a little bit frustrating,

    as it's been more than three weeks since I asked the question.

    Do you think I should wait more for indefinite time? or is it normal and is this issue actually being slowly handled by the third party?

    (I'm asking as I have to decide what to do, based on the info about how this thing is handled..)

    Unfortunately, from another source(distributor of that 3rd party),

    I've heard that that this third party (W*****h) is currently very busy while manufacturing the OEM orders,

    saying for example, the current lead time for a single unit is 4~6 months.

    If that is the case and they don't feel they need to answer this question—feeling this should be handled with very low priority,

    I guess I can only hear from the third party only after 4-6 months—hopefully which might be at around Q1 2022 or Q2 2022.

    I hope I might be wrong about them, but if this is the case what should I do?

    Can we find a way to mitigate the situation to receive the mechanical design files in time?

    This is NOT the first time evaluating the TI's EVMs. I was always able to find the required files very easily while testing.

    However, this is not he case for the DLPLCR4500EVM.

    I thought I was purchasing the TI's EVM(not the 3rd parties' EVM) which I can find the relevant resources easily as I did before.

    I hope we can find a way to handle this issue. 

    Thank you again for all your support. I hope I can hear soon.

  • Hello Kim,

    Thank you for your patience.

    I received the step file this morning only. It is uploaded in this post.




  • Wow, that's amazing.

    Thanks a lot.
