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

  1. Turn on extraction
  2. Turn on machine and it will do the homing
  3. In your computer open your file on Rhino and move it to 0.0
  4. 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
  5. Connect to printer
  6. Choose the kind of material in this case Paper/Cardboard
  7. Go to parameters -> select and change what you Cut/Engrave/Ignore and the Speed/Power
  8. 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
  9. 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
  10. Do a 10x10 square to see how the machine is cutting
  11. 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
