You might consider building a lightweight sub-table and just move that.

Mils are typically slow but very accurate. Buying a heated pad for your mill would be easy, just buy the part in any size you like. It need not be as large as the mill's table. Mounting the head could be as easy as placing it in a drill chuck. The problem would be the glacial speed. But the process is automated and you can let it run while you do something else. But I'm thinking there could be a disruptive revolution in 3D printing. There is a low cost "white light" curing resin out now. One printer uses a cell phone, face up as the "controller" and you place a glass bottom tank on top of the phone. Software draws a picture of the layer on the phone which hardens a thin layer of resin. The layer is lifted and a new pattern is displayed on the screen. Just one tiny stepper motor to lift a "weightless" (it is floating in liquid) platform from the top. A tiny battery powered motor is powerful enough. They are going to sell these printers for $100 each, retail. Larger versions use a larger LCD screen from a tablet. The commercial version of this technology uses a laser to scan the image on the bottom of the tank like an image scanner but backwards. The laster spot can be made to 0.001 resolution. Phones and tablets are closer to 1/300 inch. But the advantage of using the mill is that you could be up and running for about $100 or less.

To: [email protected] Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8; format=flowed Now that I have 3d printer (about 3 weeks now) - I am an expert. - My printer (monoprice select mini) runs at 50mm/s(118in/min) and that is considered on the slow end and very high acceleration. I think speed/acc is going to be your problem... - I have printed pla with heat on the bed and without. Both seem to work ok.

Christopher Perry > I certainly understand that a heavy mill may not be able to move as fast as a very lightweight 3d printhead and printing may take a long time. However, why would "filament control dynamics" be a problem? With the mill the table would be moving and the filament stationary which should, if anything, make the problem simpler. What am I not understanding? Or are you concerned about the movement of the object being printed? I have not experience with 3d printing. How fast do the typical inexpensive 3d printers move? ------------------------------ ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ------------------------------ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users End of Emc-users Digest, Vol 133, Issue 44 ****************************************** ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
