My first 3D Printer
a clay printer
First I looked around the web to see what others have done.
- Some reprap things:
- Universal Paste Extruder For 3D Printers by: RichRap at thingaverse.
- designboom: 3D ceramic printer"
- Brian Peters 3D Printed Bricks
- Israeli Student Develops Largest 3D Porcelain Printer
This is what I have come up with.
It is just a piece of 3/4" PVC stuck to a board and a screw with a plunger turned by a stepper (and a planetary gearbox I pulled out of a broken cordless rotary saw) to push the clay out a nozzle at the bottom of the PCV. The little stepper at the top of the picture on the right was a little to small and I borrowed a NEMA 23 motor to really get things to work.
The plunger was not quite tight enough in the PVC. You can see 2 or 3 inches of clay that slipped around the plunger in the picture on the left. So, I have added a hot glue gasket that works well.
Here are a few things I have made. Most of my work has been to make the hardware and I still have work to do to get the software end of things working.
I have also posted a video on Youtube (My 3D Printer in action). I hope to make some more improvements and post some more information about it soon. Enjoy.
