Performance Of Cross Sectional Geometries Of Beams According To Buckling Strength Which Are 3d Printed With The Same Amount Of Filament
Abstract
Aim of
this study is to determine the cross sectional geometries of beams which have
better response to buckling with the usage of same amount of filament. These
beams have the same cross sectional area and length. Thus, design points were
sorted freely without the consideration of the amount of filament, printing
time and energy consumption. Length of beams and applied forces were kept
constant for each design point, besides that basic cross sectional geometries
were changed for each design series. These geometries were selected as, circle,
rectangle, equilateral triangle, rhombus (diamond), ellipse and rounded
rectangle. Moreover four different printing material were taken into
consideration for comparison according to buckling. Depending on 6 different
cross sectional shape, 101 cross sectional area and 4 material, totally 2424
design alternatives were built. Firstly, mathematical model of these designs
were constructed, then they were tested by using finite element method (FEM)
and regression analysis. All model branches were compared to each other with
the statistical analysis. As a result of all analyses, design alternatives were
sorted according to mechanical strength.
