Desktop Laser Cutting/Engraving
bwags writes "I ran across this VersaLaser desktop Laser Cutting and Engraving printer. I really do not know what I want to do with it, but you gotta admit it is cool. Maybe make some balsa wood airplanes. At only $10K, I want the purple one!"
here is that particular page.
As they mention on their site, TechTV did a short story about it (it's the last item on the list).
Teenagers these days don't have as much sex as they want each other to think they do.
The problem with using lazer cutting on metals is that a lot of the light will reflect back up and fry the lazer. You would need to put a non-reflective coating on first. If you've ever bought stainless steel that had a white plastic sheet on it that you had to peel off, it was probably lazer cut, because the white plastic was the above mentioned non-reflective coating.
Those are all professional grade machines, I never saw those before and thank
you for the link.
However have you ever seen the
stuff Roland puts out? They make a desktop CNC mills for under $1500
that can produce small items. Leases start at $100 @ mo. They have
desktop laser 3D scanners (put a real world object in, produces 3d model) too.
Actually I sell used equipment like this, very similar machines made by the same company (www.ulsinc.com). I've burned myself a few times on them and it doesn't leave a permanent scar, but it does hurt like a crazy mofo! www.usedlasers.com is mine, if you're interested. Good Luck, Rob
If you, for instance, use this to cut out parts of model aircraft, you still have to glue the aircraft together. That, to me, sounds a bit harder than cutting it out
You haven't built any model airplanes, have you?
Laser-cut parts have been all the rage in R/C modelling for the last several years. We used to spend a hellaciously long time cutting out small parts from sheets of balsa wood, (and re-cutting when we broke a piece, or cut too far, etc.)
At these prices, it's probably within the reach of a model airplane club to buy one. Fantastic!

It is kinda slowing down, right now am getting about 20kbps.
For bigger projects there is a company called
Photomachining (http://www.photomachining.com)
that has some pretty serious laser systems that
sell for about $100k. Check it out. .
pretty neat stuff.
They'll also laser machine just about anything for
you in any custom way. Anything from PCBs to
medical devices to laser-etched guitar picks.
It's great for actually cutting stuff, for when you're using flat materials; fast, and a very small kerf.
As such it's just a 2D device. Can't do some of the more useful CNC work such as fly-cutting surfaces, pocket cutting, and 3D slopes.
If you want to do the same thing and can live with an 1/8" or 1/16" kerf, you can build a homebuilt CNC machine for an incredibly low price. Depending on what parts you make and where you get them, the price can range from near nothing to $750. Plus you get 3D profiling and a much more flexible machine: put a pen in it and sign lots of certificates, put a woodburning iron in it and make a cool clock face, put a small router in it and engrave your logo into your valve covers.
Just do a Google search for "homebuilt CNC" and you'll find plenty of good links.

In several years of working for a large laser marking/engraving system manufacturer, I've never seen reflection from the workpiece damage a laser (not sure how it could, really). If you're getting a lot of reflection, it means that the beam is not coupling well into the workpiece, which usually means you're using the wrong laser for the job. I always get a chuckle when I hear of customers trying to mark on wood with a Nd:YAG rail and complaining of poor performance.
