    I think we'll learn a lot from this thread! Way to go!

    So sorry about your failed print sukhvir!

    Keep us posted about what do you think the issue was. Apparently it looks like the light coming from the UV source is not well spreaded!?

    The pigments might have not been spreaded well either, did you shake vigorously the bottle before putting it on the VAT? did you print at 21ÂșC ambient temperature or higher during the whole print?


    -------


    SO my next failed print is brought to you by Microsoft!

    [SPAM STARTS HERE]
    The following failed print is Sponsored by Microsoft Windows 7 Windows Update System! - There's an easy, free way to help keep your PC safer and running smoothly. It's called Windows Update. All you have to do is turn it on, and you'll get the latest security and other important updates from Microsoft automatically. It will also reboot your computer right in the middle of your 3D prints, ruining them! Added value!!! Want to ruin your 3D prints? Choose Windows Update! Choose Microsoft!
    [SPAM ENDS HERE]










    So yes! While trying to print Han Solo's Blaster...



    the computer restarted overnight so the neat desktop wallpaper decided to be printed on the Morpheus over and over!!! how cool is that Bill? You owe me a bottle of MJuice you faggg....!!! lol

    Well it was not a full failure after all... (printed at 0.075micron)









    ...BUT the lesson learned after this is that the base I created was so fragile that I had to break EVERYTHING in order to remove it from the plate, so yeah, full failure in the end LOL

    The OWL works team shook the bottle vigorously before putting in the resin @bolsoncerrado. The issue with the print is that the upper layer seems fine, but the bottom layer is bumpy and softer. Print was done at ambient temperature, so I don't think that is the issue.

    I have sent details and STL file to OWL team and await their reply. I'll keep you all posted.

    You mean the print started before the team left?

    This print was done a couple of days ago. The team ran a smaller print test when they were here to calibrate resin etc. The test print I gave them broke into pieces when trying to remove from build plate

    I also noticed (after they left) that the test print should have actually printed thicker than it actually did (printed about 0.5mm thick - should have been 2mm). Might be some calibration issues but I'll keep testing and await feedback.

    If you used the resin left in the VAT by the team then you should have shaked / stirred it a bit between prints.

    I've learned the lesson as well. the hard way of course.

    I use my window wiper to slowly move the resin back and forth 10 times or so, this makes the pigment reunite again between prints.

    The other way is to put the resin back into the bottle and reshake it, or discard it and use a new bottle if you're rich

    Sounds like a plan. I emptied resin into a container, strained out the rubbish, shook and poured back in (I'm not rich enough to waste resin )

    Starting another print and have also reduced exposure time to 30s to see what effect that has. Thanks @bolsoncerrado

    Before you reduce exposure time "at random" be sure your environmental conditions do cure the resin though

    And keep us posted

    I decreased it to 35000, however found some layers in between didn't cure properly. Increased it to 45000 and got better results.

    I've decided to change resin and have ordered some FunToDo resin (Black and white). I should have it next week so will post a comparison. Seems like a better resin all round.

    I'm not sure this is due to undercuring. It's a large thin flat surface you're printing, maybe something to do with shrinkage? Looks like you tilted along the Y axis, maybe tilt a bit along the X axis as well...
    I'm using Fun To Do 'deep black' resin which seems to remain pigmented allot longer (>12h) compared to MJ G+ (<4h).

    Thanks woale. I appreciate the feedback. I have ordered some Fun To Do resin and their quality seems far better. Also, I'm going to try rotating on X and Y axis to see how it affects results.

    I thought FDM printing was hard, however it's a breeze compared to SLA so far.
