Curious. Anvil 3D printer video description. Also tagged as "best 3D printer in the USA".
Can't make this stuff up.
"Brain."
(Have to see the video to get the reference.)

Peachy printer goes public with knowledge of embezzlement.

A lot to say about this, but I'm sad to hear it. It is a tragic story. Amazing that a confession was videotaped and released.

Kickstarter definitely has a kick. It solves a couple problems, but the true test of success is surviving, shipping and maintaining a healthy company.

My heart goes out to the backers, the CEO and the employees.

$75 “Bot Spa” treatment for any metal Printrbot

https://printrbot.com/shop/bot-spa-treatment/

You pay shipping both ways, we fix anything for $75 & send it back

Yes, it's cheesy, but memorable!

We also now have free USA shipping for any orders over $200!

And we are beta testing live chat support during business hours!

We still have a few dent/dings available for 25% off too.

Good stuff happening here.

Concrete 3D printer.

I know this is crazy, but it sounds fun... I have a lot of garnet from our water jetting. I've found that it can be used to make cement. Before I make a printer that prints with concrete as the material, I want to design and make a printer that uses concrete as the chassis for the printer. Just for grins.

I've been thinking about it for a while and I think it could be a novel way to make printers that perform well when materials used in conventional 3D printer construction aren't available. You could make a printer pretty cheaply anywhere in the world. It could be a fairly large printer too. Perhaps if the concept is proven, I could use concrete to make a printer that prints concrete ;)

Instead of linear rails or other metal for all the axis, perhaps cheap plumbing pipe could be used for the X axis and concrete rails could be used for the Z axis and the y axis. I'd use the Printrbot original design for this. The bed could travel on wheels on the y rail and wheels could be used for the X axis pipe to travel up and down the concrete z axis. I think this would be the simplest design.

It would be a low resolution printer designed to make large things with a 1mm nozzle. It may not be pretty but a large nozzle would mean structurally sound objects could be made with useful utility.

I like the idea of recycling plastic locally to feed a simple printer too. Large nozzles would allow impurities to pass through if the plastic was a little dirty.

Preciousplastic.com has great plans for shredders, but they require a lot of welding. Not a big deal but theoretically, concrete could provide the structure to set the axle and bearing in and provide plenty of strength.

I got to thinking about this year's ago when I attended MakerCon and met a guy who repaired tanks in the field. They would drop machinists into an area after a battle where a bunch of broken tanks were abandoned. The first thing they would do is scavenge one of the tanks for parts and make a massive lathe out of concrete and tank parts. The man I met helped design and build these lathes. Since structural rigidity is everything in Cnc machining, he joked that they just attached the large to the earth, which didn't move much. They would do their work, then blow up the lathe before leaving. Those guys were makers!

So anyone interested in helping me design the world's first 3D printer made of concrete? Open source of course. Imagine not having to deal with and rigidity issues! ;) I suppose it would make a killer Cnc platform too.

The Big-E design is done. Some kits will ship tomorrow ;)

This video takes the cake for one of the most ridiculous promo videos for a 3D printer.

I don't normally post stuff like this but, man... It's just too over the top. What. Is. Going. On?

Refurbs/dent & dings- we have all printer models on sale for 25% off at Printrbot.com

Maybe a good time to get into 3D printing. All models have been thoroughly tested and ready to rock. All the regular warrantee and service still apply!

Cnc geeks, put your thinking caps on... Check out this article by Rob about why TinyG is special.

And why it's a big deal that we not only use the G2 in our CNCs, but why we are excited that we partnered with them to bring this tech to 3D printers. Stay tuned, it's about to very interesting ;)

All my best to the attendees going to the Midwest RepRap festival. I won't be going after all... Choosing to spend precious time w my daughter - she told me she's coming home for spring break. Just a couple days to have w her, so I choose her.

I wish you all well!!
