notes:
-
discussed that most of the work in this class is subtractive (take a bigger piece of material than the output, and subtract pieces from it).
-
saw compliant mechanisms, (one piece, one positive, one negative).
-
all laser cut machines here use inches. cms is base 10, inches is base 12.
- all materials have a sds (safety data sheet).
- introduced us to the laser cutter.
- laser is a beam of light, which is sharp-angled at the bottom (converges at a point).
- introduced kerf bending: since the beam is a triangle, if you flip the material over, the material bends.
laser printer stuff:
- stroke has to be 0.01, uniform, basic.
- the printer talks to the computer with the colour:
- no fill with stroke (one of the available colours on the template) means cut-through.
- black with no stroke will remove surface of material.
- gradient varies the power the laser uses (giving you cut-gradation).
- other settings to do on the printer itself:
- autofocus: plunger? don’t know what that is.
- split by colour, cut by vector.
- inside to outside cuts.
