Microwaves and Quadcopters!

Hi Guys,

We’ve been listening to everyone’s questions and compiling a list of things to work on to show you just what the EX¹ can do. One thing we’ve had a lot of questions about is whether the EX¹ can be used to print microwave circuits. Well, here’s a video demonstrating just that with something we whipped up in a few minutes. Enjoy!

Don’t forget, if there’s anything you’d like us to demonstrate or have any questions at all please let us know! You can message us through Kickstarter, Facebook, Twitter or email us at info@cartesianco.com.

Coming up soon - printing onto 3D printed objects!

Thank you all for your support! Team Cartesian Co.

      Woops, sorry, some one asked the same thing a 5 days ago and it looks like you're aware of it...!?!

      Wow things have really slowed down in terms of pledges. Hope yup guys are staying focussed on the campaign as I'd love you to hit some of your stretch goals.

      @Berwyn Hey, we're working on a bunch of things to put out as updates soon, but we've been slammed with so many things going on. Don't worry, more updates are at the top of our lists.

      Thanks for your offer to put out a newsletter though, it's great to know you're trying to spread the word :)

      @Charles Lehman, sorry for not responding sooner. It's getting tricky to chase everyone's comments and questions everywhere. Soon we'll have our site set up with a forum to bring everyone together.

      Anyway, this is a really good question. We've been experimenting with TQFP, and we think we should be able to get 0.8mm pitch packages to print reliably soon. We're just working on a software update at the moment, because with the way the printer handles acceleration at the moment we're getting considerably better resolution in one axis than the other. I assume you would have seen our last update where we printed a footprint for a TSSOP (0.65mm pitch) package? The reason we were able to do that now is because all the pins are aligned in one axis. Once we have the acceleration fixed printing will be that good no matter which orientation the footprint is in.

      On your question of substrate affecting resolution: yes! A lot. A material such as paper (where the ink can soak into it a little) spreads the printed patterns out, effectively lowering the resolution. Materials such as FR4, and plastics, don't let the ink spread out at all meaning that we get the highest resolution on those substrates.

      Printing on acrylic is great! It's so awesome having a see through substrate. In the few tests we've done we had to roughen up the surface of the acrylic in order to get the silver to stick well.

      Have the backers slowed down or am I just imagining things? I wonder if it's time to do another update and motivate people to spread the word to help you reach the first stretch goal -- which will ultimately let the printer build standard PCB artwork. I'll see if I can write up a company newsletter to help it along.

      Looking forward to seeing if you can get TQFP (20-30 mil lead spacing) footprints to print reliably. How much does the material affect the lead spacing you can achieve? Also, just this morning I was thinking about one of my current projects and being able to print circuits onto acrylic would be perfect for it!

      Thanks John - it's an easy job when you get to take a break by flying quads :D
