Improving Efficiency: Relation Orientation & Speed in 3D Printing. I Made It at TechShop.

Introduction: Improving Efficiency: Relation Orientation & Speed in 3D Printing. I Made It at TechShop.

     There are many way to speed up 3D Printing.   One is to make percent fill less.  Normally, users don't use 100% fill.  Normally, they range from 10% to 50%.   However, in some applications changing of percent fill might not be an option.  Or we keep everything the same, what else is possible to speed up the 3D printing.

      To verify an hypothesis on improving 3D printing speed.   To measure the speed up based on a simple shape.

       The hypothesis is not meant to include all possible shapes.  If a part is largely rectangular, having one motor move from left to right of the bed might be slower to go from one end to another.   If we place a part at 45-deg, how much speed up could we gain?
       A cylindrical or flower base shape would likely not have any significant effect.
       During our discussion, my friend at TechShop brought out a good point.  What if the extruder speed is the critical factor?  This could be very true.
       So to quickly check out this hypothesis, I decided to conduct a test. 

        If anyone know other related study, please share.  Thank you very much.

        My test samples would 5" long x 1" width x 0.25" thickness.  Due to limited material, I could only use 10% fill.and run maximum 6 tests.  10% is most common used so I think it is best to use this.  I would rotate the part 45-deg along the vertical.  I would also rotate it about the X + 45-deg about the vertical.

         Due to limited time on  3D Printer at the Shop, I would gradually update the result. I am updating the 6 alignment configuration..   In Autodesk, we only need to make 1 file.  The rotation could be done on MakerBot. 
Configurations are the following:  
    (1) 5" along X   
    (2) 5" along X sideway
    (3) 5" along Y
    (4) 5" along Y sideway
    (5) 45-deg
    (6) 45-deg sideway

       Since the test is very simplified.  No conclusion could be derived from the above exercise.  Only conclusion could be if the orientation affect the printing speed.

       This test is based on simple shape and 10% filled.  This test is based only on one simple case.  No generation should be derived from it without conducting a well planned DOE.
        I did not try to search if this test has been done in the past and analyze all factors in depth.  I simply conduct this simple and likely unscientific tests.
