Option 1: Define Model Print Order
When printing multiple duplicate parts, several efficiency issues arise as objects are often printed in a non-uniform sequence requiring additional unnecessary travel between models. This effect is particularly noticeable when printing an array of duplicate objects which require supports. Support layers for each duplicate object are printed prior to printing corresponding layers of each object which effectively doubles the travel time for each layer of the array. Experimentation with the order in which models are duplicated or added to the build plate within Cura seems to have no noticeable bearing on the sequence in which the models are printed. Model grouping also does not appear to affect model print order. Existing potential options to influence this process including the “one at a time” and “all at once” options as well as z-seam alignment customizations produce inconsistent results. An option to manually define the sequence in which models are printed could solve this issue.
Option 2: Uniform Tool-path Cloning
When a model is duplicated multiple times models are often sliced in a way such that the path of the extruder is not identical for each duplicated part. This results in inconsistency in surface finish between models. Manual adjustment of Z-seam alignment settings can be used to influence the starting position of the extruder for each model in the array but does not guarantee identical tool-path travel for each layer. An option to clone the tool-path relative to the model would provide greatly enhanced surface finish consistency between duplicate models.
Option 3: Per Model Settings – Build Plate Adhesion
An option to manually select build plate adhesion on a per model basis would be beneficial in printing multiples of different models in a single print job where each model may require unique brim or raft settings would be beneficial in improving efficiency.
