I also 3D modeled and printed the canopy. This is the first time I’ve tried printing with clear resins in my DLP printer and I ended up doing three prints before I figured out the configuration and parameters needed to get a successful print. As it was, it took 13.5 hours to print and it isn’t transparent coming out of the printer. This image is of the canopy after spending about two hours wet sanding with 600 to 1500 grit paper, then moving to rubbing and polishing compound, finishing with composite headlight lens cleaner (Mother’s brand). I still have to print the frames that will sit on top of the clear glazing. That’s next.

Not intending to take anything away from that canopy, it's beautiful, but I get good results in minutes with plunge molding. I don't get a frame though. The difference is just time.

Don, you don't know how many times I thought about that while I was buffing this thing! :) I was really interested in seeing what results I could get with the clear resins, and this was a great test. The interesting thing is that I could use this method to create the plug/buck for plunge molding. I could use the standard resins, which are very heat tolerant at the temps used for melted clear plastic. Maybe I'll try that next time.

If I had one of those things, I would be trying lots of stuff too. I have a hard enough time just with the computer though.
