Over the summer while visiting relatives in Massachusetts, I attempted to use my revopoint miraco to scan as much of the dinosaur footprints as possible in holyoke.
The Revopoint Miraco uses projected infrared light to track it's position and measure depth so this scanner is useless outdoors in broad daylight. The scan used here was done at a half hour before sunrise.
If I ever figure out how to fix the alignment issues i may upload the bigger file. For now, here's one of the better individual footprints I scanned.
In fact, it seems there appears to be a second footprint from a much smaller theropod just to the right of the big print.
This file is quite large in size and measures about 22" wide by 25.6" long. I've used LuBan to cut it up so as to be printable full scale on a prusa mini, but included the complete stl for those who wish to cut it up for different printers or print it out at other scales/sizes
Here is more information about where this footprint came from
https://en.wikipedia.org/wiki/Dinosaur_Footprints_Reservation
I have indicated where this footprint was scanned in the map shown in photos. Its indicated with an orange arrow and is circled in orange.
There are signs at the site that make it very clear that making plaster casts of the prints is prohibited. Scanning and printing is definitely the way to go.
Print times and filament usage indicated above are just for printing full size. It will of course be a lot more reasonable if printing this scaled down.
The author marked this model as their own original creation.
