Remixed from https://www.thingiverse.com/thing:45930 Topology optimization with toppy is handled here: https://code.google.com/p/topy/ Watch a video of the entire process at http://youtu.be/LTsEBuIUHTA This thing has been updated; I added DXF and SCAD files, smoothing and thresholding them to create an improved part. The quick release design from mrwolfe also inspired me; check out this additional STL model in a similar style. Here's how to build one: Making Your Topology Optimized Part Step One: Understand the Basic Workflow Define your solid regions carefully - these are where your materials will reside. Identify the areas you want left empty for this model and create separate definitions. I have done so with my design, creating holes that allow a smooth rod from my RepRap to slide through along with rods supporting my spool. Boundary and Load Conditions Define these terms as they pertain to the boundaries of your material and load requirements for this piece. In this instance I defined an upper boundary with downward force applied directly beneath the point where two parts intersect - also creating lower forces placed under opposing rods closest towards opposite directions around central pin that holds things firmly together; which balances tension perfectly across all sides. The first step to doing any kind of topology-optimized model involves understanding what goes into each region - your main goal being finding right material layout needed according needs you want part fulfilled. For me it meant focusing strictly solids & making holes specifically where there shouldn’t be no content since empty space does serve its purpose just like non solid shapes add clarity through precision control needed in modeling stage. Once established start playing with force direction because different pressures acting throughout will produce optimal design which meets specific load requirements best. Step Two: Run Topology Optimization Using Topy Refer back to code documentation and tutorials on topy site. For best results make sure input settings are precise. Step Three: Work With Gimp And Inkscape To Refine Model Further - Smoothen Out Rough Areas After Optimizing Process Has Been Finished And Import Output Directly Onto CAD Tool
