Moon Base? What?
:D :cool: :P
http://news.discovery.com/space/print-me-a-moon-base-130201.htm
"“3D printing offers a potential means of facilitating lunar settlement with reduced logistics from Earth,” said Scott Hovland of ESA’s human spaceflight team. “The new possibilities this work opens up can then be considered by international space agencies as part of the current development of a common exploration strategy.”

So, lunar condos might be possible after all — but let’s just hope the “ink” doesn’t cost more than the printer and that paper jams are a rare annoyance."

Direct Metal Laser Sintering technology (DMLS)
http://en.wikipedia.org/wiki/Direct_metal_laser_sintering

Hmmm, never heard of that before.  Pretty cool.

This looks to be a different process than what Shapeways  uses.  They sinter the stainless steel then bake in bronze.  It don't look like they are doing that here.

Yeah, the uniformed thugs will have a hayday with this one:

http://www.morristech.com/Technologies/?cat=DMLS

It will be easier to purchase Uranium than it will sintered stainless steel powder.

The quality isn't perfect, but it's pretty good:

When compared to casting metals, that looks pretty good.  Still looks a long way away from 3D printing a Meyer WFC injector spark plug with out completely machining the surface anyway.

I've seen this technology before, it's amazingly accurate. I have a friend who's X son-in-law works at a company that has five of these printers, up in Waco TX. He invited me to see these machines in operation. Also gave me a sample. It's a 2" high watch tower chess piece, with a spiral staircase inside with steps, very precision work.:cool::cool:

This quote from the Matt's link addresses my biggest fear for the home DIY RepRap 3D printer community.  Even though I totally agree with open sourcing gun plans and to legally be able to print a gun for your own use, I don't promote it online or in my videos.  I haven't tried to print actual gun parts myself as of yet.  I own many of my own guns, and reload much of my own ammunition.  I believe we need to use this technology responsibly, and should use 3D printing to help save the world rather than let it go to waste and resort to shooting it up.  Beware that TPTB will use tactics like below to stop decentralized open source production.

In other words, the Solid Concepts gun still requires expensive, industrial-grade equipment that most DIY enthusiasts or homeowners can't afford. That makes the metal gun very different from the plastic guns of Defense Distributed, a Texas group that has developed an open-source design for guns intended for manufacture using home 3-D printers.

Defense Distributed's plastic guns haven't proven durable enough to survive more than a few shots. But the group's focus on plastic firearms produced by cheaper varieties of 3-D printers has raised fears that 3-D printers and open-source gun blueprints could theoretically allow anyone to make a gun at home—either legally or illegally.

Such fears have already driven lawmakers to propose laws that would restrict the manufacture of 3-D–printed plastic guns. Police in Manchester, UK went so far as to seize a 3-D printer and what they claimed to be 3-D–printed gun parts from a private home last month. (The police quickly backed off their claim after people pointed out that the parts displayed in police photos appeared to be printer parts.)

Yes, Nate there are unquestionably some issues with "high end" 3 D printer gun making, being confused with RepRap 3 D printers. Those five high end 3 D printers that I was invited to see in operation were a low ball figure of $100,000.00 each. So with the precision needed to print a gun is in no way available with a RepRap and the cost forget it, out of my price range. To,  I believe it's not by mistake that the news media is reporting these falsehoods, it is a scare tactic to again control the masses.:huh:

This thing made me smile  :D

So What color is your favorite??

Hey Guys I am Working On building a CNC Router/ 3D Printer. I already ave the X and Y Slides and Ball Screws But Need the Z and the Electronics.

I am going to need someone that has some experience with these devices to head me in the right direction. The Y Axis On the Bottom Weighs 32LBs  the X is the same assembly but I have stripped the mounting rails and mounting plate from the Slide  assembly to reduce its weight. I have also designed and ordered a Z ball Screw from China :

I need to order the motors and drivers I think I want to use the following motors and drivers Unless you guys can send me in a better direction.

http://www.ebay.com/itm/NEMA-34-Stepper-Motor-1600oz-in-150mm-5-7A-or-2-8A-80VDC-5-6A-Digital-Drive-/121036799688?pt=LH_DefaultDomain_0&hash=item1c2e5afec8


Also Below is a picture of my design.
Feel Free to make comments on the design. I welcome any suggestions.
 I don't know very much about these devices  an you guys may see some some gotchas that I am not thinking about.

I have not thought much about the print head and or router spindle motor Yet.

Suggestions any one. :P

Hi Allgood-Energy
One item to suggest is start a build thread and if you haven't already take a look at this thread here on the forum,
http://www.open-source-energy.org/?tid=376

It might give you some part ideas. The stepper motors you are looking at look good, you will need a little more torque than the stepper motors we use for the printers we have built. Along with that have you thought about what software you will use to run the router/printer, if not you might look at Mach3, or Matt might have some suggestions on that and the router to use. Your design looks solid, just might beef up the Y axis support on the left and right. What is the travel height going to be on the Z axis? :D
PS: Take a look at this thread as well
http://www.open-source-energy.org/?tid=1327

I'm not saying to buy this but looks good.

You may want to look at these:
http://probotix.com/3_axis_stepper_motor_driver_kits/

I think price-wise they may be cheaper for the complete kits.  I have the ProboStep units with a USB controller and 40 volt, high amp toroid power supply.  This all came with their Fireball X90 unit I purchased.

At least take a look and see if you can save a few dollars.  I can already tell you their kits work wonderfully, so you'll have no problems that way.

For the router spindle, I really like my Dewalt unit.  It has variable speed and illumination lights for the work surface.

Also on the lead screws, be sure to use anti-backlash nuts.

Probably good to poke around on the Probotix site and get some ideas of parts and assemblies.  You'll see pretty quick what will work and what may not.

Hi Allgood-Energy
One item to suggest is start a build thread and if you haven't already take a look at this thread here on the forum,

So How do you Create a new Thread I May not have the ability to create an new thread.

I have never seen an buttons for that purpose.

can you direct me how to create this thread??


 So do you think I am going for overkill on the motor sizes.

Frame 34 1200 oz.  This is approximately 33"W X 33"D X 40"H
 The Slides are 1" diameter that I have laying around.  plenty beefy.  I am worried about the weight of the X and Z tied together Where the Z will have to lift upwards of 50 LBs when you include the spindle.
I am going to purchase Mach 3 I found a place that has it for $150.00
I need to check it out because saving $25 isn't worth messing a round for if the seller wont support you. I think you can get it from Mach 3 for $175
What other software is needed to accomplish 3 D and routing???
What does a post processor do??: huh: I am new to this 3 D printing Stuff.
I have Fixed NC machines for years but never got much involved in the Programming.

Mach3 is supported through a Yahoo forum [very good support], you will have to sign up though.
Well with steppers you want torque and not so much speed. What your looking at should work. Here is a site I've purchased from in the past.

First go here:
http://open-source-energy.org/?fid=40

Then click, "New Thread" in top right.  That should give you an editor screen.  Next pick "Builder" as the thread prefix, a title and have at it.  If you get tangled up, just give a holler (PM or email) to one of us and we'll get you going.
