MAS 863 - David Carr My final project is a 3-axis CNC milling machine that costs less than $100 (currently $87) to build. It can mill PCBs, wood, and even mild steel. These PCBs were milled using the machine. The traces are 10-15 mils. Some more test pieces: MDO and mild steel with a 1/32 inch mill on the left, wax with a 1/8 mill on the right. Design My design was heavily influnced by Johnathan Ward's MTM-AZ, although it shares no common parts with his machine. Machine drawings (DXF) Bill of materials Brute force stepper driver The brute force stepper driver is a simple 3 axis stepper driver for use with EMC2. Here are the files for milling the board: Bottom (PNG) Holes (PNG) Mill the first/bottom layer with a 1/64 inch mill first. Components MDO frame Y,Z axis gantry assembly Bed and X axis assembly Spindle assembly Stepper motor drive board PC control software Processes All of the machine's structure is MDO and is designed to be milled on the ShopBot. Schedule Over and out.
Tech Biz Chinese Scientists Are 3D Printing Ears and Livers – With Living Tissue Specially modified 3D printers use live cells that could theoretically be transplanted. Researchers in China have been able to successfully print human organs using specialized 3D printers that use living cells instead of plastic. Researchers at Hangzhou Dianzi University actually went as far as inventing their own 3D printer for the complex task, dubbed the “Regenovo.” “Xu Mingen, Regenovo's developer, said that it takes the printer under an hour to produce either a mini liver sample or a four to five inch ear cartilage sample. According to Xu, the Regenovo can print in a sterilized environment with temperatures ranging between 23 and 500 degrees Fahrenheit. Xu admits that the science fiction-inspired body part printer is still in its infancy, with much fine-tuning needed to realize the Regenovo’s full potential. “Before printing you can preview the print path of each layer and determine suitable speed and temperature. Here is a video of Dr.

Make CNC DIY Projects & Products | MakeCNC.com howie m » Amateur CNC mill show and tell Friday, November 19, 2010 Amateur CNC mill show and tell Thought I’d have a go at something a bit mechanical for a change. Mmm… precision drilling… mmm… OK, back to me: CNC mills are all the rage at the moment - loads of people seem to be building them, from huge ones through to tiny little ones you can knock up for very little money. I’ve got loads of electronic junk in boxes, so I had a dig around. It’s a scanner - a disco/nightclub light that can change colour and, using a motorised mirror, shine the beam around the room in carefully choreographed patterns. These things are the heart of a CNC machine - you can control precisely how much its shaft rotates, unlike a normal motor that spins freely when you give it power. I managed to scavenge a load of bearings and rods from old printers. I bought a few lengths of leadscrew from Marchant Dice (yay! I also bought a matching tap, to make the nuts that’ll be driven by the screw. Drill a hole in it: First: X-axis stuff Next: Z-axis stuff
OpenBuilds Part Store 3D printing: a replicator and teleporter in every home In a few years, 3D printers will become a consumer electronics commodity. Today you can buy a MakerBot Thing-O-Matic, “the latest in cutting edge personal manufacturing technology,” for $2,500. You can plug it into your computer via USB, load up some freely-available 3D modeling software, and print stuff; it really is that simple. The only real barrier to mass adoption is the initial purchase price, and the printing material itself isn’t cheap either. Both of these costs will tumble in coming years, however. In other words, in a few short years, every household will have a device that’s capable of printing any solid object, and even basic mechanical objects. The next step will be 3D printers that come pre-loaded with popular designs. With our current grasp of additive manufacturing, we could do these things now. Now imagine the possibilities of 3D printing if you combined it with other technologies. Which brings us onto the topic of replication and teleportation.
