Sierpinski's Tetrahedra (Fractal Tetrahedra)

pinshape

Summary Sierpinski's Tetrahedra Calculated by OpenSCAD Initial Parameters Set for Fractal Level = 5, Thickd = 0.5 (mm) Print Settings Printer: Da Vinci 2.0 Rafts: Doesn't Matter Supports: Doesn't Matter Notes: This Object Is Very Fragile - Handle with Care! I Experienced Difficulty Printing the Fractal Object at Level 4. When Removing Supports, I Broke Many Parts and Had to Glue Them Together Using Acetone. Acetone Was Also Helpful in Making the Bone Structure Firmly. The STL Files Are 1.0mm Normalized Size and Were Generated as Is. Please See Comments in OpenSCAD Source for Size Specs and Rotation Angle. These STL Files May Not Be Suitable for Printing - I Recommend Each Printer Use OpenSCAD, Adjust the Thickd & Thickr Parameters, and Print. Thickd Adds Thickness to the Contact Point; If Too Small, the Object Cannot Be Printed. If Too Big, Smaller "Eyes" Will Be Blocked. Thickr Adds Proportional Thickness, but I Don't Think It's Useful - If Certain Amount, Then "Eyes" Won't Be Ordered Equally and Will Not Look Beautiful. You May Think It's Better to Rotate to the "Normal Angle" - Top Corner, Bottom Surface Tetrahedron. However, Each Part Has Ceilings That Need Supports. It's Hard to Remove the Support Without Hurting the "Point Contact" Part of Tetrahedra. I Also Tried Rotating to the Bottom Corner with 3 Outer Supports Generated Simultaneously in OpenSCAD, and to the Bottom Edge with Supports Generated by MeshMixer. On My Printer, the Bottom Corner Failed Because the "Point Contact" Parts Cannot Stand the Reversed Tetrahedra. The Bottom Edge Failed Because of the Supports Firmly Getting Into the Object (Still Trying). If Certain Supports Could Be Generated, Direction of the Bottom Edge Would Be the Best. The Tetra-Nosup.scad Source Is for Generating the Bottom Corner with 3 Outer Supports, and the Generated Example (70.7mm Edge, 0.5mm Contact Point) Is at Tetra5-70_7d0_5revsup_fixed.stl.
