arfink Posted August 5, 2013 Author Share Posted August 5, 2013 So this is what happens when the laser hits a hidden knot. At first it doesn't look that bad. Maybe a little extra soot or something, should clean up ok, right? Well, for starters, this black crud won't come off with a brush, so it's not soot... The other side reveals the truth: this is resin from the knot, which has blackened and stained the surrounding wood when heated by the laser. The knot also blocks the path of the laser, which causes it to not cut cleanly all the way through, leaving nasty chips like this in the edge.

AnneLine Posted August 6, 2013 Share Posted August 6, 2013 Thought of you when I read this... and AM I GLAD YOU ARE ON OUR SIDE, ARFink!!!!! Researchers show how to 3D-print housekeys ...Applications for 3D printing are creeping into all facets of our lives — both good and bad. While craftspeople and DIY enthusiasts have new ways to create objects straight from a CAD file, there are also applications that have made people very uneasy. Cody Wilson has famously been working on a 3D printed gun, for instance. Scanners are the other half of 3D printing’s power — being able to capture the dimensions of an object, turn it into a digital file and then print it back off again. The two students claim that the keys can even be replicated from a simple photograph. Keys may say “Do not replicate†at the top, but that doesn’t mean people will listen...... http://blog.sfgate.com/techchron/2013/08/05/researchers-show-how-to-3d-print-housekeys/ Link to comment Share on other sites More sharing options...
arfink Posted August 6, 2013 Author Share Posted August 6, 2013 You could always have duplicated keys before the advent of a 3d printer. ;) Just sayin. And as for making firearms, I could make a better one with a CNC mill or even a hand-operated Bridgeport mill, and I could buy those for less than the cost of the Stratasys printer I'd need to make a gun. See, this is how I see it. The internet has made access to information and the means of spreading it nearly universal, and unstoppable. Rapid manufacturing will do the same with manufacturing, it will make it more universal. Of course, then things will go back to the way they were before the industrial revolution, where more people knew how to make more things, as opposed to right now, where most people don't know how to make anything, or only know how to make one kind of thing.

arfink Posted August 7, 2013 Author Share Posted August 7, 2013 The varnish is done. It'll be hard as nails in a few days, but for now I couldn't resist putting the parts in. Good gracious this thing is GLORIOUSLY shiny! You do not want to know how many hours went into making this thing. :P It was a lot. And I still need to wire it. But the hard parts are all done now.

arfink Posted August 9, 2013 Author Share Posted August 9, 2013 Today I am working on the electrical system for my joystick. I also found this cool video of what a pneumatic transport tube (like the ones in banks and hospitals) sees as it travels through the system. http://www.adnbr.co.uk/articles/shooting-a-camera-through-a-pneumatic-transport-system [media]http://vimeo.com/72028965[/media] Link to comment Share on other sites More sharing options...
