Andrey is starting to print concrete tiny houses outside now! Can you guess what it’s going to be from the foundation?

Of course, printing outside in 95’F heat makes it hard to cool the drivers… and when they are moving a monster the size of a small house, overheating is an option. Normally the THB6064AH will go into shutdown when it over-temps, but combined with running at max voltage (or maybe over?) chips were blown! That is the first. time. ever. that I have seen a fried THB6064AH.

Way to make a mess buddy!

Now… the GOOD part about making an open source driver kit is… you know how to repair it! New chips cost $10 and with a bit of time on the soldering iron, Andrey is back up and running.

Castle Print Update-
It took some time to prepare the printer for printing outdoors since I had to figure out all the cables and waterproof all the switches- in addition to the unexpected problem that the past couple weeks have been insanely hot and the drivers have been overheating. If it’s 95 degrees F (35 Celsius) outside, there is no way to cool down below 95, even if you have a large fan and heatsink.
I finally got it all figured out (thanks to James Newton), and I am continuing with the print.
In addition, I have confirmed my theory, and I know for sure the layers are drying quickly enough for me to print nonstop.

@Fleur_Al_Dridge Andrey is planning to print full sized houses all the way. Just to be clear, this is his machine, my involvement is supplying the open source high power stepper motor drivers that run it:

I’m a little confused… Oh, you mean electrics installed in the house! So plumbing, etc… can be set in by hand between layers or added after the fact. Notice that there are two thin walls which will be filled in later. This is really pretty close to traditional concrete construction, but with forms that are very custom. He is already laying in rebar and so on as it prints.

Wow! this is awesome. A question just came up recently in another thread, how to include rebar in a 3D printed house - and the double wall construction seems to do it.

With a third wall, maybe we could add insulation too - though perhaps there is a way to print that that would be better. Then add weather proofing, and it would be done.
