DIY, 3D Printing in your own garage
So, in the world of awesome, for those of you interesting in a good DIY weekend project, looks like someone’s put up a DIY guide on Instructables that covers how to build your own Stereolithographic 3D Printer.
Stereolithography (SLA) , is a form of 3D printing which makes use of a laser to trace a 3D object into a photopolymer UV-curable liquid resin, one layer at a time. The UV light cures each layer and adheres it to the layer below. The main advantage with SLA over other methods of 3D printing is that this method is accurate enough to be used for making prototype models for manufacturing, and in some cases you can even create decent sized working parts (gears, screws, knobs…etc.).
While there are places online where you can send your 3d .STL files or CAD files to be printed by various companies to print things for you using an SLA method, it can be expensive (not that building it yourself will be cheap). Besides, for the exuberantly enthused hobbyist, whom we’re all about enabling, this is way cooler.
This DIY recommends all the parts you will need to complete this project. For the laser, Aixiz is recommended for the 405nm 20mW laser you’ll be needing. Normally I wouldn’t go out of my way mention such an obscure thing… except, deep down, I’m still waiting for someone to make a decent practically use out of the insanely powerful Wicked Lasers. But I’m probably just being unrealistic again.

In closing, 3D printing is the future of production. Maybe some people still see it as a mere novelty, but believe me, 20 years from now, you will buy the part on Amazon, then print it off in your 3D printer, with nothing to ship. Cloths, mechanical parts, tuber-ware, drapes, curtains, sheets, bike parts, you name it, there will come a day when you simply buy the plans and print them out on your hp 3d printer.
