Voronoi Dog
Introduction: Voronoi Dog
Hi All,
In this instructable, I will share, how I made this Voronoi pattern dog
Supplies
* 3d Printer
* Meshmixer
* Cura
* TinkerCad
Step 1: Download a 3d Model
* 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
Step 2: Meshmixer 1/3
* 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
Step 3: Meshmixer 2/3
* 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
Step 4: Meshmizer 3/3
* 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
Step 5: Cura Settings
* 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%
Step 6: Printing and Cleanup
* 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 974
