Techshop SF has 60W Helix lasers...probably nicer than what we'd be able to
afford by scrobbling together cash - a similar item used on ebay goes for
These are some nice laz0rs too - they can actually cut things (though not
metal). A couple examples: 3/8" thick wood, 1/4" acrylic, and a bunch of
If you want to use Techshop lasers by yourself, and whenever you want, you
have to take a class (~$35), and then you have to pay by the day you are in
there ($50/day). You can probably use the laser for about 6 hours or so each
day you pay for just in terms of scheduling.
There is a way to use Techshop much cheaper too - you can come in with one
of us Noisebridgers that are TS members, and your daily rate drops in half
($25/day). Additionally, I'm qualified on the lasers, so I can get you
moving without having to take the class.
So, just doing some quick math. If you can use lasers for 6 hours a day for
$25, that means we could buy 600 days at techshop for $15k (the cost of
buying our own laser), otherwise known as 3600 hours of laser cutting.
Additionally, we wouldn't need to worry about maintenance or upkeep or
damage on our own equipment. Do we really think we're going to use a laser
this much to justify the cost?
