Week03: computer-controlled cutting
Assignment
- group assignment: make lasercutter test part(s), varying cutting settings and slot dimensions
- individual assignment: cut something on the vinylcutter
design, make, and document a parametric press-fit construction kit, accounting for the lasercutter kerf, which can be assembled in multiple ways
group assignment
make lasercutter test part(s), varying cutting settings and slot dimensions
I made the slot dimensions sample board by fusion 360. My card board thickness is approximately 3mm. Test slot dimensions are 3.0 ± 0.2 mm.
Then export to DXF file.
download .f3d
download .dxf
Open DXF file in CorelDRAW. Re-type the text which did not import correctly and set line color for laser cut.
download .cdr
Send data to laser cutter's driver
Laser Cutter: Universal VLS 2.30
Material: approx. 3mm cardboard

Slot dimensions 2.80mm fitted well, but may not be enough to keep other piece strong.
So, I made the narrow slot dimensions sample.
download .cdr
Slot dimensions 2.60mm is strongly fitted to hold each other.
Vector cut line (red) parameter made much soot, so I try to find better soot less parameter.

No.5 Red is the same as cut line of slot dimensions sample.
I tried some faster speed and less PPI.

All circles are cut. No.1 was very less soot. So I will use this parameter to make press-fit kit.
individual assignment
cut something on the vinylcutter
I made a simple STL object by Fusion 360.
download .f3d
Import STL file to Pepakura and make it flat.
download .pdo
Then, export to DXF fire.
download .dxf
Import the DXF file to Silhouette Studio
download .studio3
Cut by Silhouette CAMEO
Then fold....
Paper Cutter is very useful tool to cut thin material. I almost think Paper Cutter is older style than Laser Cutter in any ways, but it is not correct. Paper Cutter is still one of the choices in digital fabrication.
design, make, and document a parametric press-fit construction kit, accounting for the lasercutter kerf, which can be assembled in multiple ways
Design 3D model by fusion 360
download .f3d
Then export DXF file from each sketch
download .dxf
download .dxf
Import DXF files to inkscape, then adjust lines and set line color for laser cut
Import to CorelDRAW and send to Laser Cutter driver
download .cdr
Then cut
Assemble one unit
Assemble in multiple ways
