Sprint 1 Milestone - From MTK to CADQuery to 3D Printer

Added by J. Simmons over 5 years ago

Drum roll please.....

I am very happy to announce that the Yavin team has successfully demonstrated the end to end vision of doing an analysis in MTK, integrating that analysis into a CAD model in CADQuery, and then manufacturing the part using a 3D printer. Take a look at these photos to see the whole story.

We start the process by coding up the engineering analysis in Python on documenting/verifying the analysis in MTK.

Next, we code the CAD model up in CADQuery and export the resulting geometry to an STL file.

The STL file goes into our slicing tool (I am using MatterControl) and we generate the GCODE to send to our 3D printer.

Then all that is left is to upload the GCODE to the 3D pinter and wait for the part to come out (I am using OctoPi to run my PrintrBot Simple Metal)

And here are the results! Look at how closely the printed part matches the CAD geometry from a visual inspection. Note, this is just a demonstration model. We have not calibrated any of our printers, so we are not going for engineering precision or strength (yet).

And here is another view of the printed part.

Finally, I took a couple of measurements using my calipers. I measured the wall thickness to be about 4.1 +/- 0.1 mm (compared to a calculated value of 3.8 mm in MTK). And the inner diameter of the chamber was 39.8 +/- 0.1 mm (compared to a specified radius of 20.0 mm, or a diameter of 40.0 mm). Not too shabby for an uncalibrated printer just printing a demonstration model.
