The different Digital fabrication techniques¶
Process¶
Make Human¶
• Adjust the modelling part to make it like yourself
• Then at the end you change the measure part to make it more accurate
• To save it go to files -> export -> save it as mesh format in .obj and .stl
Rhino after Make Human¶
• Import your .obj file as Nothing
• Right click in the tabs on the right (top, perspective, front, right) and select shadded
• Write distance in command to see the size of your object
• Write scale in command to change the scale of your object, make it 10x or 100x bigger to make it as a real huamn size
• Convert your mesh in mesh NURB to make it as an open mesh
You can't trim in open mesh
• Create a polyline where you want to trim your human
• Write trim in command -> select the polyline -> select the part that you want to trim -> delete
To select the part that you want to trim you have to select it from right to left
• Then you save your file as .obj
SCAKNEKT¶
• Scan body by moving the table pressing conctantly E+ and by moving robot the robot from top to bottom by pressing Z-/+
• Make the model waterlight to close mesh
• Save and export in .obj with and without texture, in .stl, and .ply
Rhino after Scanning¶
• Export your .obj file
• Right click in the tabs on the right (top, perspective, front, right) and select rendered
• Write distance in command to see the size of your object
• Write scale in command to change the scale of your object, make it 10x or 100x bigger to make it as a real huamn size
• Make a polyline in the middle from top to bottom, another one from shoe to shoe, activate midpoint
• Activate Gumball and rotate to make the line from gumball and the polyline you made from top to bottom coincide
• ExtrudeCRV -> move the surface to where you want to cut the body
• ExtrudeSRF -> select surface -> create a box (in solid)
• Delete the Extrusion but not the box
• Mesh tab -> from NURBS Object -> Convert box in mesh
• Write MeshBooleanSplit in command -> select the body and then the box -> delete
• Delete everything except the center of the body that you need
• Save as .obj
Slicer - Fusion 360¶
• Import your .obj file that you just did from rhino
• Change your object size in mm, then original size, and add a 0 to make it real size
• Change your board's measurements in manufacturing settings -> custom -> mm -> 900/600/4.0/0.0 for a small board and 2400/1200/4.0/0.0 for a big one.
If your pieces don't fit the boards you can change the wigth 600 or 1200 and the length 900 or 2400
• To save, go to get plans -> save as .dxf
Rhino after Slicer¶
• Import your .dxf file with ingonre thickness
• Nest the pieces in the board to save material
• Do the tolerence test by taking 2 of your pieces and putting them outside of the board
Rhino to laser cuting¶
To cut¶
- Turn on extraction
- Turn on machine and it will do the homing
- In your computer open your file on Rhino and move it to 0.0
- Go to print -> Adjustment -> Put the size of your material -> Set and move the paper to 0.0 and make sure your scale is 1x1 -> Print
- Connect to printer
- Choose the kind of material in this case Paper/Cardboard
- Go to parameters -> select and change what you Cut/Engrave/Ignore and the Speed/Power
- Back to the laser cuting machine, after the homing the bed will go down so you will have to move it by pressing the up button
- Then you focus: Set your material where you want on the bed -> Move your head to the middle of your material -> Take the focus tool and put it on the head -> Move the bed up until the focus tool falls
- Do a 10x10 square to see how the machine is cutting
- Cut the tolerence test and if it is working cut the rest!
Useful tips:¶
- If there is too much smoke, clean the lens
- If it does not cut, you may have to make it 2D
- Print Settings of Rhino: Vector to cut and Ruster for image
- If it does not cut well you might have to lesser the speed

What I would improve/change¶
• I would have add color to my mannequin, I wanted to do a mannequin inspired in the Venezuelian artist Cruz Diez. Maybe I will disassemble my mannequin and paint the boards.
• I think I would have distorted less the mannequin
• I would also use the scanning method and use tight cloths to make it even more accurate
