This seems to be important to ensure the order in which they are handled. The above files should be imported into Simplif圓D with the "Prep" file preceeding the "Model" file for each color. Repeat the above for the other color creating a file with the prep rectangle and another with the model components to be printed in black.This will be the "Model" file (in this case G.stl). This should be everything in the grey layer with the exception of the prep rectangle (which could live in it's own layer or in the default layer). The second file to export will consist of the model components to be printed in the first color.Export this selection to a ".stl" file (in this case "GP.stl"). Then select the bounding box from the default layer and the prep rectangle from the grey layer. Select the grey layer and make the black layer invisible.
Now we create four ".stl" files for import into Simplif圓D: For the purposes of this demo it was easier to show it as I have. The "prep" should really be on the default layer as it makes it easier to select the model for export (you can to a select all without having to deselect the prep object).Make sure that the base of your model, the bounding box, and the two prep areas are all on the same place on the Z axis!.Please see the caveat at the end of this instructable for a discussion about this technique. The "prep" objects should be as tall as the last place where both nozzles are used. You should have one of these for each color as part of the two layers.
The two little rectangles in the upper left and right corners are intended to serve as "prep" areas for the extruders and will serve in a similar manner as an initial skirt would do for a single extruder model. Remember that you move things from layer to layer using the entity info form (right click).įor demonstration purposes I have only two elements of my model with the plaque being one (with an indent for the letters "Sara") and the actual letters being the other. You can either design element by element in the appropriate layer or, more likely, develop the model and then segregate into appropriate Sketchup layers. Create two new layers in Sketchup with one being for each color that is needed for your model.
