CT or MRI to 3D-print
Dicom to STL
Embedded Files
Use of Local Computer
Use of Local Computer
Advantage:
No need to send the files somewhere, all done on my own computer
No queuing or waiting time for processing the 3D-model
More possibilities to crop and make the segmentation (but can be time consuming...)
Both CT and MRI-images can be processed
This is the Local Computer workflow I have tried, works on Mac and PC:
1. Make a 3D-model with 3D-Slicer
1. Make a 3D-model with 3D-Slicer
2. Repair and adjust for 3D-printing the 3D-model (Mesh)
2. Repair and adjust for 3D-printing the 3D-model (Mesh)
Dicom (CT 2D files) -> Mesh (STL 3D-model) -> repair, adjust -> make a 3D-print

Choose a scan serie and click Load
Crop with ROI, Use the Volume Rendering Module
Crop with ROI, Use the Volume Rendering Module
Display On (the eye), Select a Volume
Center the 3D-view
Choose (try) a Preset: CT-AAA
Crop Enabled, Display ROI On
Shrink the "box". Drag the "spheres"
Display ROI Off
Display Off (the eye),
Go to the Crop Module

Segmentation, Different Paths
Segmentation, Different Paths
A. Using the Segment Editor
A. Using the Segment Editor
A manual approach. More work done in 3D-Slicer. Possibility to make separate parts. This is more precise! But might be time consuming...
B. Using the Gray Scale Model Maker
B. Using the Gray Scale Model Maker
An automatic approach. More work done outside 3D-Slicer after a quick STL-export. Especially if not 3D-printing this could be a very useful shortcut!
A. Using the Segment Editor
A. Using the Segment Editor
Open the Segment Editor
+Add Segment
Open the color swatch and choose Bone (you can choose your own color and name)
Show 3D
Click Threshold and adjust the levels as good as possibly
Click Paint
Enable Sphere brush
Adjust Diameter, watch in the 3D-view
Rotate the 3D-view and then Enable Edit in 3D views. Brush in 3D. Then disable to be ably to rotate again
Click Erase and adjust
Click Scissor and cut
Click Smoothing and clean up
Click Island and Apply to get rid of tiny debris
Here you can continue by having different segments (parts) or just make it really clean.
When you are done it´s time to export.
Go to the Segmentation module
Scroll down
Mark Models
Export
Click Save
Change to STL
Save, the STL is now in the folder
B. Using the Gray Scale Model Maker
B. Using the Gray Scale Model Maker
To "Quick"-export an STL we go to the Gray Scale Model Maker
Input Volume: ... cropped
Output Geometry: Create new model as...
Name the export: GrayScaleExport150
Threshold: 150
Smoth 15
Decimate 0.25 (reduce mesh/file size)
Apply
Click Save in the top main menu
Select GrayScaleExport150
Change to STL
Save, the STL is now in the folder
2. Repair and adjust for 3D-printing the 3D-model (Mesh)
2. Repair and adjust for 3D-printing the 3D-model (Mesh)
Now we have an STL-file! Let´s see if it´s good for 3D-printing.
Open it in MeshMixer (alt. Blender or any other polygon software you prefer)
Cut out the interesting part
Select and delete, use Plane Cut as well
Check with the Inspector for holes or imperfections
Seperate Shells to find "extra" pieces
Resize (check size) to fit your 3D-printer
If "heavy" you might reduce the mesh count
Export as an STL-file
Optional but recommended
Optional but recommended
Open in Old Netfabb free
Click Analyze and hope for an "Yes, Yes"
If not there is a possibility foe an easy repair with Extras > Repair Part. Good stuff!
With two green yes from Netfabb we know that we have a 3D-printable 3D-model
