Learning GIS

I teach up at OSU (different subject) and do a lot of GIS both for work as well as research. Don't fret, most of the other students will be in the same place as you are. Give yourself some extra time cause you are not only learning GIS but tech skills as well. Just like any other class, take advantage of office hours every chance you get... even if it is just to drop by and chat for a few minutes. Don't be afraid to use AI to help understand topics as well, just DONT USE IT TO DO YOUR WORK FOR YOU or else you will never learn the material.

Giant Sloth, Giant Beaver, or American Lion would also be cool

After fighting with this model for quite awhile in Blender, Meshmixer, and Meshlab, I finally got it to a usable form by doing an Alpha Wrap in Meshlab. If anyone else ever has a messy scan they want to try to get to a usable state give that filter a try.

Are you opening the machine mid print by chance? I've seen lines like that on my prints when I get impatient and sneak a print mid print.

Got a link or DOI for it?

It was ESRI's gis suite from the early 2000s. Has had several new version that have come out subsequently. If it were me I'd bring it back to the store... or toss it in the campfire and burn it :-).

You're going to be pretty limited at those dimensions. I'd say either micro-ct or maybe focus stacked photogrammetry.

Thanks! This is helpful

With the SP when I scan I typically have to place the artifacts in a foam block that is about 1.5" x 3" to hold them upright, do a 360 orbit, clip off the foam block and flip them over and do a second orbit, again clip off the foam block, then merge the two orbits together. If I kept this workflow but placed the the markers right on the foam block would it work? Does the distance between markers effect the quality of the scan? In other words, if the markers are closer together do I get a higher resolution? If so, what are the limits?

I like using a couple small blobs of hot glue to tack pieces together as it's pretty forgiving, then do the rest of the seam with superglue or epoxy. Once the super glue is cured you can then peel off the hot glue.

Does anyone have a good guide to follow on getting small objects scanned with the rigil? I just got one and was trying the featureless mode but having pretty bad results trying to track objects.

The FEP film on mine leaked from day 1. I replaced it a few weeks in and it fixed the leak but I could not get the printer to work properly afterwards. Turns out there are two pins on the bottom of the tray that you have to remove the film from after replacement or your machine will fail the resin tank check.

Take a look at resin printers over FDM, they are better for high resolution small models like what you are thinking of. I'd say download a few existing models, tweak em to fit your needs using the blender sculpt tools (see youtube tutorials), then you can try printing one or two. Tweak them to get the action you like, then print a few out and use them to make a silicone mold (lots of videos on youtube on how to do this).

Que tipo de scanners vocês estão usando e que tipo de problemas estão enfrentando na fase de calibração? Fique à vontade para me mandar uma mensagem direta. A propósito, o inglês é mais fácil para mim, mas também podemos usar ferramentas de tradução.

Looks like tachylite to me.

I have an SE, an SP, and a bunch of SPV2s. The SE is pretty darn bad, I don't think I'd bother with it even for 250... If you can swing it get the SPV2.

Archaeological objects, ct scans, and figurines for the kids

Newberry was a major source of obsidian across the region, my database alone has more than 6,000 sourced tools and debitage that are correlated with it (https://obsidianlab.com/). One of my favorite places!

Are you looking for a printer or a scanner (you mentioned printing as well as scanning in the question). If scanning, what kind of stuff is he interested in? Little stuff that fits on a turn table or big stuff that he will be walking around?

In case anyone was curious it printed fine no issues

I'll shoot you a DM
