Ultimaker: How to print with PVA support


Using PVA support material significantly
increases the quality of models that need support material PVA supports can be dissolved in water and supported areas of your model will have a high quality finish In this print guide we’ll explain how to use Ultimaker Cura 3.0 to print a model with PVA supports Open a model file by clicking the “Open File” button in the left toolbar Ultimaker Cura 3.0 supports all major 3D file types, including STL, OBJ, X3D, and 3MF The model will open in the 3D viewer Left click the model to highlight it and use the adjustment tools These tools can be used to position, scale, and rotate the model Printing with PVA gives you complete geometric freedom You don’t need to worry about print defects when printing overhangs or bridges For engineering models you can rotate your model to ensure layer bonding is strongest in the desired direction In the right side bar, check that the print cores and materials match your physical
setup on the printer Extruder 1 should contain an AA 0.4 print core loaded with PLA Extruder 2 should contain a BB 0.4 print core loaded with PVA Printing with PVA support material can be done in recommended mode Recommended mode has four simple options to configure the printing profile The print quality slider: Let’s set the resolution to 150 micron to get a quick, strong print Infill density: Increase this to 50% to ensure the model is strong Generate support: When this checkbox is enabled, supports will be generated around the model A new option will appear underneath to assign a support extruder Use the drop-down box to select extruder
2 as the support extruder This will ensure that support material is printed with PVA using the BB print core Build plate adhesion: Let’s keep this enabled to prevent warping Wait for the software to finish slicing the model Slicing progress is shown at the bottom-right corner of the screen All print settings are set, and you can now preview the result To see the different layers of your model, change the view mode from solid to layers by clicking the view mode button The layer slider has three components: The top and bottom handles can be dragged to set the visible layer range The solid part of the slider can be used to drag that layer range up and down to scroll through the printing strategy The layer view has multiple color schemes We can set it to line type or material color The line type view makes it easy to
identify different line segments, While material color easily distinguishes
which parts are printed with which material Additional information about the print job is shown at the bottom-right of the screen such as the file name, the model size, estimated print time, and estimated material usage When you are happy with the preview, save the file, or print directly from the software Click “Save to file”, “Save to removable disk”, or “Print over network” at the bottom-right corner of the screen That’s it! You’re all set and ready to start 3D printing Thank you for choosing Ultimaker
