Also 90-95% of print failures are due to a bad first layer (citation needed).

your reference. Solidworks does have a point cloud tool but no idea how good it is. Working with surfaces in Solidworks usually is not hugely fun.

All I really need is to get the surface data into something other than a “mesh” format. My actual job is working with Catia V5, but my work does not have any of the applicable Catia licenses to directly work with mesh files (such as STLs). If I can get to that point I’m golden. I have plenty of experience working with and creating surfaces.

FreeCad can apparently make a step file from meshes with a few steps, but when I did that with a simple 1 2 3 block scan, the result was about 2.5GB’s, and tends to lock up anything that tries to open it. I may look into an open source program to create usable surfaces from point clouds instead of trying to use meshes.

Well, this is with a RevoPoint Pop2. This is 2 or 3 scans merged into 1, no editing outside of the scanning software. I’ve been extremely impressed at how well this can scan and produce a 3D printable STL. The only thing I haven’t figured out is how to get a file with the surfaces usable in CAD software. I can pull the STL in and see it, but not constrain it or create intersections with it.

For scanning, Epic Games has a phone app that I’ve seen seriously impressive results from just photogrammetry. I did not have very good luck with it, but it is definitely capable of great results. If you have a newer iphone, some of them have a depth sensor and apps available that can 3D scan.

If you want to scan primarily 3-8" objects the Pop2 is great. It’s even at what are probably clearance prices at Amazon right now ($400-450 USD). I bought mine used/open box directly from Revopoint via ebay for $400. Definitely get the turntable. It is definitely worth the extra $50.

Yes lol. Souvenir from the dinosaur casting museum in Tucumcari, NM.

The top fin kept the details, and you can tell there were scales, but all the fine lines are basically gone.

Two more pictures of the original and copy(s).

Quick T Rex toy scan (~4-5" long); the black claws didn’t show up. scanned on the side they did, but they didn’t merge well. Coelacanth figure again ~5" long. The texture of individual scans on this guy looks amazing, but falls apart when merged together. The mesh itself looked quite decent with the merge though. Both of these could be 3D printed as is.

Here are some screenshots of scans. The head is my scan of the included sample part, and the 1 2 3 block is a machinist tool that is exactly 1 x 2 x 3 inches. I 3D printed it, and with calipers it checked about .010" off per 1", or roughly 1% “small”. That is with zero CAD work or scaling.

Have you tried the reality scan app by Epic games? I did not get great results from the one scan I tried, but I’ve seen really good scans, and it doesn’t care how fast you go or what direction.

That being said, as long as the revopoint keeps tracking: no errors. The only times I’ve had it lose tracking were when scanning a 1 2 3 block without spray (shiny metal) and when trying to scan my car dash in a fairly dark garage (high gloss black). For anything shiny and maybe very dark, you need spray of some sort; either the purpose made stuff or talc free foot spray.

The meshes can vary from mostly smooth with some bumps to kind of having a fish scale effect, but the later is from over scanning. Apparently you should always scan either one rotation on the table or only roughly 300 frames at a time for the cleanest result. You can convince as many scans as you want though. As I said below I’ll screenshots of my results later tonight.

For 6" objects the POP line is perfect. For people or people sized objects the Range looks significantly better, but the range might struggle with 6" objects. I guess it’s pretty common for people who get into 3d scanning to have multiple scanners based on what size you are scanning. The POP 2 can scan people, but you have to move a maybe 5x5 or 6x6 “window” around them to get all the detail. The Range had a significant larger view/window to scan people much much faster. The faster you can scan the less likely it is to lose tracking.``

Sorry, it’s revopoint not revoscan. It’s easy to say the wrong one when all you see if the software day to day… I fixed my comment above. I’ll try to get some screenshots up later today, but I’ve scanned lots of things with the turntable and I scanned my 21 month old when he was asleep on his beanbag.

I just recently got a Revopoint Pop 2, and I’ve been thoroughly impressed by it. I feel anyone looking at 3D scanners needs to keep expectations in check (they are not magic), and it takes work to get good scans, but personally I think it’s well worth looking at Revoscan. For hand size and up, the Pop 2 or Pop 3 are great size. The mini is for very small objects, and I’m not sure of the Range can do that small (but it looks SIGNIFICANTLY better for larger objects). I’ve only had it for a week, but do you have any questions on it?

Also, check their ebay store. I got the Pop 2 openbox that way directly from Revopoint, and it was only $350 for the base, or $400 for the complete kit with turntable, battery bank, and case. The turntable alone is DEFINITELY worth the extra $50.
