The New Hotness

  • Tyvek Engraving: FAIL

    Spurred by Jason’s comment on the laser test paper trials, I engraved some Tyvek:

    You probably can’t see the “Test!” engraved below the blue logo, as it just changed the texture of the envelope without producing a visible mark.

    The upper-right “Test!” ran at 10% (of 60 W) at 400 mm/s, with the others at 15% and 20%. The results suggest that it’s possible to remove ink and leave a visible mark, but it’s neither pretty nor dependable.

    Somebody’s gotta have a weather-stable, super-flexy, dual-color, laserable material, but so far it’s hidden below my horizon.
