Litho filament calibration tool
Description
One Of The Keys To Creating A Good Litho Print Is To Develop The Full Range Of Shading In The Image. If You Make The Print Too Thin, The Image Will Be Washed Out, And If You Make The Print Too Thick, The Image Will Be Too Dark. Since Different Filaments Allow The Light To Pass Through Varying Amounts And Various Light Sources Have Different Brightness And Color, The Thickness Of The Litho Really Needs To Be Selected On A Case By Case Basis. This Tool Can Be Printed With The Desired Filament And Then Held Up To The Selected Light Source To Determine Which Thickness Will Provide The Best Image. This Is A Graduated Platform In Which Each Substep Increases 0.1Mm In Thickness. Ten Substeps Make Up One Long Step. The Very First Substep Would Be Zero, But Was Made A Full 10Mm In This Design. The Substeps Gradually Increase To 0.9Mm At The Far Side Of The Long Step. The Subsequent Step Then Begins At 1.0Mm And Increases To 1.9Mm. Thus, By Holding This Block Up To The Light Source, You Can Read Off The Exact Thickness To 0.1Mm That Will Give You The Full Range Of "Colors" In Your Image. You Can See From These Prints That My First Layer Is 0.3Mm, So The 0.1Mm And 0.2Mm Steps Were Not Printed. The Photos Show A Comparison Of A Translucent Green Filament And A Wood Filament. They Also Show How A Standard Incandescent Nightlight Bulb Would Require A Thicker Print Than A White 12V El Panel .
