Instructions

  1. Preparing the 3d model file 
    • Select one object prepared 3d scanned for SAMPLE. 
    • Prepare to fix the surface, make sure it’s watertight (meaning there are no holes) if it’s spiky you need to remesh, smoothen or reduce mesh in mesh mixer so it’s 3d printable. 3D printers can only print solid objects, if your object is not watertight and is composed of surfaces, it won’t work. Follow the tutorial Only From min 2.34 to 6.33, discard the rest. 
    • Create a new rhino file in mm units and Import the fixed model to Rhino  
    • Make sure your units are in mm, type “units” enter to check 
    • Rotate your object in such a way that the longest side is lying flat on the grid plane 
    • Select your object and type “boundingbox” and hit enter, this will create a 3d bounding box around your model to help you scale it. 
    • Scale the object, select both the box and the object and type “scale” enter, select the long side of your object, select the first vertex of the box, then the second vertex and type 30mm (3cm) and enter. 
    • Select both the bounding box and your object and center the model at the origin, to do so make sure both are selected, type “Align” enter, select “concentric” or type C and enter, type 0 and enter, this will allow you to center your model at the origin 0. 
    • Delete the box, select your object, go to File > Export Selected and save your object in Stl format. 
    • Now you’re done, next step is using a slicing software to slice your object for the 3d printer. 
  2. Slicing the file and 3d printing – Group work.
    • Download and Install PrusaSlicer 
    • Watch this introduction tutorial to understand what are the different settings.
    • Download both configuration files from this link, this will import the settings for the machines used in the Fablab, the Creality CR10. Import them in Prusa Slicer from File > Import Config Bundle, (not import config). 
    • Drag and drop your model inside the slicer 
    • Select the printer, from the right column dropdown menu, CR10V2 with ABL under user presets. 
    • Decide what kind of supports you need and select it accordingly 
    • Click on Slice Now 
    • Detach the microSD card from one of the printers, put it in a microSD card reader and save the sliced file into the SD card. 
    • Launch your print, make sure you stay at least 15 min next to the printers to guarantee that the print is successful.
