The 3d extrusion process
the concept: to translate a 2 dimensional image into a 3 dimension print.
the process:
1) Find an image
- pay attention to how the image stands. You need enough of a flat bottom on the image to keep the 3d model standing upright
- look for simple images, the image will be translated into black and white (literally)
2) Photoshop (used to translate the image into black and white with a transparent background)
- Threshold - to turn the image into just black and white
-- this can be done many times using duplicate layers
- Look for floating black shaped. The black areas are the areas the will be printed. Make sure all black shapes touch other black shapes.
- While having a clear background layer. Using the Magic Wand to select the white parts of the image. Make sure "contiguous" is un checked.
- Delete the white areas
- Image Size to 400 pixels on the longest side
- Save for Web as a PNG 24 with transparency
3) Flash (used to translate the bitmap into a vector)
- Open Flash
-- Under Create New pick "Actionscript 2.0"
- File --> Import to the Stage --> pick you PNG
- Fit the PNG to the stage if the stage is too small, goto Modify Document and make it bigger
- Modify --> Bitmap --> Trace Bitmap
- Export the Image as an Adobe FXG
- Use Save As to save the image as a .FLA
4) Illustrator (to save the file as the correct file format)
- Open Illustrator
- Use File Open to open your .FXG file
- Adjust the Art Board if necessary using the "Artboard Tool"
- Use Save As to save your file as an SVG
5) 123D Design (used to extrude the vector image into the 3rd dimension)
- Open 123D Design, click the red button to close the startup panel
- Use "Import SVG" to pull you SVG file into 123D Design
- Under "Construct" use the "Extrude Tool"
-- click on you image and pull it up.
- Use "Export STL" to make your 3d ready file
