Blacksmithing and Casting Cause!

So after the previous Blacksmithing cause never reached official cause status and months of stagnation, I’m excited to let everyone know this cause has received exec approval and merely waiting on paperwork to become official.

With that laid out, onto the details.

My name is Alex Wixted, and most of you will have seen me around the space over the past 8 months or so. After not seeing anyone else willing to step up and be active as a Cause Champion, I have taken that upon myself, mostly because I wanted to play with fire and bang on hot metal, but also to see what projects members will come up with when they have a usable workspace and tooling. I have very little experience when it comes to all this stuff, so will be making up as I go along with guidance from the internet and other cause members when it comes to projects and classes.

I have submitted the cause proposal found here to the exec and have received majority approval, with the final approval resting on completion of registration with the treasurer.

Currently the Cause is looking a little like this:

Cause Champion: Alex Wixted (@wixted)

more complex forms.

Have you considered a microwave furnace?

  • Instructible1
  • Pop Sci article2
  • “Lost PLA” 3


  • 1000+w microwave (Emitter must be in top, not side of unit)
  • Graphite crucible
  • Silicon Carbide susceptor
  • cinder bricks, cement paste, high-temp insulation
  • Venting apparatus

@AussieLauren: @Svenska has experimented with a microwave furnace at HSBNE before, and pointed me in the direction of The FossCar project Lost PLA casting.

I’m keen to give it a go, but it will be after we have basic functionality!


I’m happy to help with that and add my very little experience.

I approve of your reasons for becoming the Cause Champion!

I’m still sorting out what needs to be done on the Treasury end of things, and I will advise as soon as that’s completed.
