We will create (2-3) different 2D and 3D infill patterns that are not yet implemented in CURA that has documentation of their structural properties based on real world applications, generating a lattice like structure within the boundaries of an arbitrary shape. We want to know the minimum infill required while retaining the structurally integrity of larger infill patterns. For example, the trapezoid shape provides structural integrity while also reducing quantity. <\/p>\n\n\n\n
We will compare these new generated infill patterns with existing patterns and evaluate them in difference of speed, filament waste (density), and strength. Speed will be determined by the comparing the time to existing infill patterns with the same density. Filament waste will be determined by the weight of the pattern generated. Strength will be determined by the “popsicle bridge test”. Where every pattern will be printed to the same shape and infill density and will be tested to see at what point them fail. The given pattern will be subjective to increasing amounts of vertical stress until failure (or until we run out of weight).<\/p>\n\n\n\n
We will create infill pattern through extruder turtle so we can control the path taken by the nozzle. The motivation for this is to reduce the unnecessary movements at each layer when creating the infill pattern.<\/p>\n\n\n\n
Week of November 4th: Research what type of patterns aid in structural strength and provide the most value while reducing cost. Looking into support structures such as buildings and bridges will help.<\/p>\n\n\n\n
Week of November 11th: Start working on creating our own infill pattern by using extruder turtle.<\/p>\n\n\n\n
Week of November 14-21 : Test our infill pattern by using our 3D printers to see the type of pattern is viable. <\/p>\n\n\n\n
Week of November 28-Dec 6: Quantitively prove the structure integrity of our pattern <\/p>\n\n\n\n
