    Resin Curing test

    Open up your bottles and start testing!

    I've used the attached pattern (available on Onshape, download on Thingiverse) to run some curing tests with "Fun To Do deep black" resin (MakerJuice G+ to come later):

    The pattern is 5cm x 5cm, with sufficient detail to see differences at each exposure attempt.

    I'll try to keep a table with the "sweet spot" best exposure times for each tested resin:

    Resin Layer height Exposure Time Bottom Exposure Bottom Layers Ambient Temp
    FTD Deep Black 100 17000 ms 50000 ms 5 21C

    Some pics

    FTD Deep Black comparison. The top 3 "prints" are simple single layer curing tests without using the build plate, each with different UV exposure duration. The bottom 2 "prints" are multi layer prints using the build plate, with 50sec UV exposure on the bottom layers and 17sec for the remaining layers.

    FTD print detail of the "cross" on the succeeding print under a microscope.

    Love the idea! Let's build a nice table!

    but most important i see on this test is... ROOM TEMPERATURE!!

    Can you email me the .stl file? Or edit the attachment and .ZIP it instead?

    Sure, but not before Wednesday. Meanwhile, could you try Onshape (link above), which allows to "export" part and download as STL file.

    @angrypanda.. thanks for starting this thread.. what tool did you use to cure your prints? Or did you just expose your prints to room temperature for 17-50 seconds? I am just trying to understand what you meant by 17-50 seconds..

    Hi acnow. I believe the bottom layers had an exposure time of 50s and the rest of the layers were exposed for 17s.

    woale started it

    and you need to set your "exposure time" to different combinations until you find the best that suits your printing, resin and ambient temp needs and report back with pics (ie the perfect cure) by slicing the provided STL and "printing" it with the printer.
