Voronoi Dog

Hi All,

In this instructable, I will share, how I made this Voronoi pattern dog

• 3d Printer
• Meshmixer
• Cura
• TinkerCad

• Go to your favorite 3d Model site
• I like Thingiverse.com
• I would recommend picking a low poly model instead of full poly
• For this instructable I used https://www.thingiverse.com/thing:446787
• You can choose any other model too

my model is avaliable at https://www.thingiverse.com/thing:4792489

• If you do not have Meshmixer, download and install from https://www.meshmixer.com/download.html
• Import the stl file into Meshmixer
• After import, you will notice the surface is different than you expected
• To fix this, click on Edit and select Generate Face Groups, This should fix the shape
• Now under Edit, select Make Pattern
• As soon as you select it, the default is Tiled Tubes, you can change the pattern using Pattern Type dropdown
• You can experiment with the different patterns but for out Voronoi we need to select "Dual Edges" or "Mesh + Delaunay Dual edges"
• You can play with the "Element dimension" and "element spacing" for desired thickness
• Once happy, press the Accept button, it may take a few minutes while Meshmixer processes the model

• After Meshmixer is done processing, it may have cracks or error
• In this case, it does show them as red dots
• Just to be sure, select Analysis and then Inspector
• You will be able to see all the defects, I typically select Auto repair all and then Done

• Many times the base of the model is not flat, it may not print well
• To avoid this you can either slice the base by 0.5 to 1mm
• Or Add a base
• I created a 2mm thick 100mm circular disc in tinkercad, and export it as stl file
• Now import this disc in Meshmixer, select Append
• Use object browser to select the disc and Generate face groups
• Under Edit, use transform to align the dog and the base
• In Object browser select the dog and the base, option to combine automatically pops up
• Select Combine and then export the model

• Install Cylinder custom support and restart Cura
• Import the model in Cura
• Do not activate Supports use custom supports
• We need to add support where needed, for this model, I added just on
• Resolution 0.28mm
• Reduced scale to 80%

• Export the gcode from Cura and print it
• It took 3.5 hrs for me
• Once done, you will notice that there is a lot of stringing
• Use a hair drier to melt the string
• Since we did not use supports, there will be some sagging but does not standout

I hope you will try this method and do share your feedback and suggestions
