Yeah, I know what my next project is going to be!
Looks like it's basically a small MIG welder with 3 axis control.

"Now Professor Joshua Pearce and his team of 3D apostles from Michigan Technological University are proclaiming the era of Open Access 3D Printing, having published their “A Low-Cost, Open-Source Metal 3-D Printer,” article in the journal, IEEE Access. Practically anyone who is interested is now free to print objects and make a 3D metal printer of their own."

Here's a direct link to the Open Source Documents.

Having recently come into a good chunk of money, this is sorely tempting. However as with all new technology, its probably best to wait and give them time to work out any bugs.

I'll see your 3D metal printer and raise you a tabletop 5-axis CNC machine!

Awesome idea but the precision is rather lacking...

That said, gives a good base to further machine from.

$3500 for a 5-axis?! Now that, that is well worth it for the hobbyist. Can't wait for that kickstarter to pop up!


That said, check out: http://www.tormach.com/

These guys have quality, cost, and ingenuity down pat. <10K for an industrial level machine is unheard of.

You can build a plastic printer for under $300.

yep, I had a very similar idea a while ago. But the real issue of something like this is that your resolution is going to be horrible. That and I have very real doubts that something like a printed hammer head won't just crumble the first time you try to use it to strike something hard or snap the claws off the back of a carpenters hammers.You wouldn't be able to print something like a cross head screw driver, or any of the bits for a drill. and I wouldn't trust a printed iron bench to hold my light weight.

I like the idea better of printing in PLA and making a mold, and burning out the PLA before casting iron or brass.

$300 you say? But plastic hmmm....

I'm looking for something to make transitions and elbows for my art. Don't need high spec. but I think I'll need a smoother surface than this will easily do. Still looks neat.
Looking at a 4' x 8' build from Bosch strut for a wood router/ CNC plywood cutter. Vacuum through pegboard for the base, a good program and I could make some kicking sides for the tear drop trailers.

Now there are 3D metal printers that can output tiny precision parts, not only with moly, but with tungsten & stainless steel too says the company. Where's that winning lottery ticket already. markf

I was thinking about ways to make something like this, and the idea I had was wire feed welder + CNC machine or something like MIG / TIG welding depending on what you wanted to create. Possibly forcing a semi-liquid flux loaded with the metalic substances out of a controlled nozzle and zapping it with electricity to create bonding to occur.

The company I work for (ASML) already uses this metal printing technique for a few years. Here we use a technique called D.M.S. which stands for Direct Metal Sintering (By a company called Parker from the UK).

Here's what a presentation from them says about their technique:

What is DMS?
- As SLS (Select Laser Sintering) but with metal
- using a high powered laser (up to 400 Watts)
- Parts are built, not cut.
- Input data direct from CAD
- Parts are lasered 1 layer at a time 0.02mm.
- Build bed drops.
- Next layer of resin is spread.
- Resins are not ‘real’ material.

DMS materials
- Stainless steel
- Cobalt Chrome
- Inconel
- Titanium
- Aluminum
- Nickel Alloy
- Maraging Steel

I'm not posting the presentation because I'm not sure if I'm allowed to post it because it's specific to my company's development department.

We also work with a company called "LayerWise". They do some parts manufacturing in Titanium.
Here's some work they do:
