Preparation for laser cut
PDF files saved from 123D make
were uploaded and opened in Adobe Illustrator and the colours of the outlines
were changed to make sure that the outline of the templates need to be cut
are red, and the numbering are blue just to get the scratched useful as a guide
in assembling the cut out pieces for form-work. Stroke
weight needs to be changed to 0.001 mm for successful cut. Used 4 sheets of 3mm plywood 600*300 for laser cut (check the quality of the plywood to make sure it is
not bent for successful cut through the sheet).
PDF templates for laser cut
Saved (.AI) files from Adode
Illustrator after setting and opened those files in laser cutter application.
Opened the laser cutter printer application and setting the material to natural
plywood with cutting depth of 3.5 mm added extra 0.5 mm for successful cut
because plywood sheets were bend. Turned on the laser cutter. Placed the
plywood on the laser cutting bed and adjusted the focus point of the laser
cutter using the focusing tool to make sure all the templates are within the
boundaries (repositionthe the sheet if needed). Shut the lid, turn on the
extractors and press play button. Approximate cutting time was 6 mins for each
sheet, repeated the same process for each sheet. Regardless of the
extractors,wise to wear the mask because of the strong fumes produced from
laser cutter for Health & Safety.
Cut out plywood sheets
Total 50 pieces were stacked to test the alignment
Top 12 layers were
decided to removed to test on another possible Polaroid camera shape
Constructing the form-work
Used UHU glue to
assemble the form-work and the alignment holes from laser cutter guided the
alignment of the model.
Final form-work and
ready for metal shaping
