3D Printed HUGE Autobot Matrix

Well, I took it to task to work on a request from Optimus Puto to print a human scale Matrix that could be opened.

I found a small one by TFMCDerek on thingiverse: http://www.thingiverse.com/thing:842691

The model opens, and it's already separated into multiple pieces. My printer is only so big, so pieces was really good.

It took about 42 hours to print, made one scrap piece (the pin).

All parts were printed at 10,000 scale except for the pin, which I had to make at 9,900 scale (1% smaller). The original 10,000 scale pin is the scrap piece.

In total, I used just shy of 400g of plastic (that includes the scrap piece and supports).

In addition to the printing time, There was probably close to 3 to 5 hours of setup and cleaning of pieces, test fitting, code generating, etc.

The external cracks are due to thermal shrinking of the plastic, something I hadn't considered, but can be covered with paint (which the holder still needs). If I ever print another, I can compensate and minimize for it now after some research.

The pieces themselves are still solid and can be handled and manhandled, but I really wouldn't try going through a drop test on this.

With a little bit of careful effort, the container can be split open, just like the movie.

Originally I wanted the pin to be removable, but it is such a tight fit that it is never coming out. I ended up using Kraggle to fix it in place within the core.

Handles still need to be attached to the container, and the container still needs to be painted. I'll leave that to Optimus Puto, since I have some chemical sensitivity to many paints and solvents. Its a shame I don't have yellow/orange plastic, or it wouldn't need the paint.

Anyways, here's the pics of the (almost) final product. Titans Return Cerebros for scale.

"Nobody can be told what the matrix is... They have to see it for themselves"
Now they can. That is awesome!

Re: 3D Printed HUGE Autobot Matrix

That's awesome! If you can, I'd love the file for that thing. I just got a 3D printer and work and this would put it to the test nicely.

Check the first post in the thread, there's a link to the original .stl files. You'll need to print the container and handle twice.

I'd give advice on some settings, but since I have no idea what kind of printer or material (I did ABS on a MakerFarm Prusa i3v), my settings likely wouldn't work.

I will say this, the original is microscopic, so you'll at the very least need to upsize it to 2.5x the size. Mine is about 100x the size of the original file.

Also, make sure the pin is smaller than the holes it needs to go into. And the container part is the only one that needs support when printing.

There are other versions of the Matrix on Thingiverse, but this one was the only one on short notice that was split into separate pieces and that could open.

Best of luck. And have fun.

Re: 3D Printed HUGE Autobot Matrix

Amazing! Is there some hollowness (low infill setting) or is it solid? Mighty impressive that's for sure....

5% 3d honeycomb infill for all but the pin, that's got 20%

If it were solid, I'd probably still be printing the second part.
