memo) For some reason, when I imported a SVG file created in Inkscape, the shape changed. I tried using Illustrator to test it and it worked!

6.1 Select the data you want to output from the imported files.

6.2 Click start nest alt text

6.3 It will automatically line up and when it is done, select the SVG file from Export. alt text

7.cut

I have cut the parts of the parametric construction kit with the following values.

  • Using FABOOL Laser CO2
  • power : 20%, speed : 1250 mm/min, time : 2(See results of group assignment)

Impressions

  • This week was a busy week for me as I was away from home for three days for a school event!
  • The laser cutter is convenient, but I learned that it is dangerous because it can catch fire.
  • I think the space between the parts I made was a little narrow.I considered it an appropriate value because it did not fall out when I shook it, but I thought it should be a little wider because it was hard when I fitted it.
