iro3d

World's first affordable metal 3D printer.

The video "Simple way to 3D print glass, part 1" was too long for Twitter, so, you can only watch it on YouTube: https://t.co/a7qZzAlgkS

Simple way to 3D print glass, part 2 - chainmail.

Now we have a large printer. Let's call it "Model G". The specs are on the website.

3D printed copper-nickel dog-bones for tensile strength testing. This is our first copper-nickel print that looks defect free. Our previous copper-nickel print had bubbles because of the high oxygen content in the copper. But for this print we have used "oxygen-free" copper.

Also, the brass looked shiny right out of the crucible - without any sandblasting. No mill scale whatsoever. Compare it to the copper-iron rooks on the sides. (Even though the copper-iron was sandblasted, and the brass was not.)

Today we have tried printing with copper powder and brass infill. Surprisingly, this the copper powder, which was gas atomized, flows almost like water. It can flow easily through 0.4 mm hole. We need to make a new pourer for it, to take the full advantage of this property.

Can we print with tungsten carbide powder?

Comparison: sandblasted parts on the left, wire brushed on the right.

[iro3d @iro3d_com]

Today we have sandblasted a few of our 3D prints. I wish we have tried it sooner. Sandblaster works so much better than a wire brush.

It looks like a good applications for iro3d printer is to make molds
(for plastic injection molding) with conformal cooling channels.

Usually those molds cost a lot of money. We can print them for a small fraction of the cost.

Just a heads up: On June 1st, 2019, the price for the standard size of iro3d printer will go up to $6000. Order before that day to take advantage of the old low price.

This video shows the new version of iro3d metal printer. It has the same build volume, but weighs much less. So, it's easier to ship. Also, this design can be scaled up, to print huge objects, something like an engine block or a vault door.

To meet the growing demand, we are starting to look for partners who would build and sell the printers under their brand. We will provide the manufacturing files, the controller board, and the slicer. The printers shall have a label, saying "Licensed by https://t.co/Z4qTdOUfNq"

I am curious what they are saying. Anyone knows Chinese?

Today, one of our customers have measured Ultimate Tensile Strength of a bar, which he has printed on iro3d printer. He have got 445MPa, which, I think, is pretty good for copper-iron.

This is my first ever video interview. Jeremiah Craig is a popular singer-songwriter. In this video we talk about 3D printing and play guitars :-)

What would be the best color for the printer?

[iro3d @iro3d_com]

For this print we have used a better copper than for the previous two. The result is much nicer.

[iro3d @iro3d_com]

We have tried printing copper-nickel and it works. And, like copper-iron, it's easily machinable.

[iro3d @iro3d_com]

Today we have tried to post-process our 3D printed copper-iron heat exchanger on a lathe. As expected, copper-iron is easily machinable. 🙂
