Get ready to see a lot more older vehicles back out on the road as shops will be able to precision manufacture parts for older cars.

3-D Printer Ping!

Political power grows out of the nozzle of a 3-D Printer.

Why did they print screw heads where the screws are supposed to go?

Oh, man, and you think printer cartridges are expensive now...

“Get ready to see a lot more older vehicles back out on the road as shops will be able to precision manufacture parts for older cars.”

That’s exactly my business plan. Getting ready to produce some finished products now, they’ve been in R&D.

If you could make vintage Willys and AMC parts better, I would be a good customer.

Those are temporary fillers that support the upper surface of the hole.

What about grain structure? Grain growth?

These aren’t that expensive, in fact, they’re a steel...

Those are supports for the top side of the holes. There’s still some finishing needed for the final net shape for that generation of printers (it’s an older image).

Nice. However I’m pretty sure that’s machined from billet, not 3-D printed.

I'm certain you are wrong, go to Solid Concept's web site and see for yourself.

Metal 3-D printing is now making many near net METAL parts.

StrataSys is one vendor.

Desktop Metal is an other.

NASA and Space-X are 3-d printing rocket engines.

Someone printed a complete all metal M1911 some 7 years ago. Eager to see the equipment costs drop from ~$1M to garage-friendly.

The EBAM® 300 Series Produces the Largest 3D Printed Metal Parts & Prototypes in the Additive Manufacturing Market

With a maximum work envelope of 19' x 4' x 4' x 8’ (L x W x H x D, or round parts up to 96” diameter), the EBAM® 300 Series by Sciaky offers the largest build platform of any metal 3d printer commercially available.

Designed to additively manufacture large-scale parts and prototypes from high-value metals like titanium, tantalum, Inconel, niobium, and other alloys, the EBAM300 is the only 3D printer on the market that has produced a metal structure exceeding 10 feet in length.

Very interesting.

As the printer uses a laser and essentially is a sintering process, this could lead to inexpensive metal printers.

If these printers come down to even $20,000 each... Wow.

I wonder if this printer would be adaptable to this process.

It is only $50K, from Australia, and has a chamber 8"x8"x10", a pretty useful size.

You have to check this out: How Adam Savage built a real Iron Man suit that flies

No joke. They built to withstand a pistol bullet (and demonstrate it) all on a 3D printer.

I have recently gotten into 3D printing, it is a blast, though somewhat frustrating at times. I have been using a cheap, Chinese Creality Ender-3 printer, and I got a lemon. after months of struggling, I finally got the bugs ironed out, but it served its purpose.

I didn't want to be one of those people who spends all this money on something and never uses it, so I bought this cheap printer for $175, and while I had no end of trouble with it, it was like owning my first car. I knew nothing about cars, but after owning a notoriously unreliable MG Midget, I learned all about cars.

Same with this printer. So I purchased a new one a couple weeks ago, a pretty expensive one, and purchased some real 3D software.

When I hadn't heard back a week after ordering it, I sent a polite email and left a call inquiring about the status. I fully understand with everything going on there will be delays, I just wanted to ensure the order went through.

The CEO personally called me back to give me an update, and the next morning, emailed me a picture of my printer being assembled...:)

(he said mine was the one on the left...:)

I like that. One of the reasons I chose the company was because the product was American Made, and the support experiences sounded like this call from the CEO-great customer service comes from the top down.

Yeah! Good luck!

I had heard some years back that 3D printing was going to revolutionize industry from manufacturing to building houses.

I read an interesting article that predicted that many parts will not be built and shipped in the future...they will be printed at the destination-even in your house.

I saw a cool video that showed how to use 3D printing to create a mold-I find this entire endeavor very exciting.
