Third test of the scan plate concept.
I think I missed something (and I don’t have Facebook): what is that “scan plate”? Is there an stl-file to 3D-print the surface, or how is it done?
The “scan plate” is a device I’ve been working on to facilitate scanning of feature-poor subjects. I can supply a SVG file for laser cutting the parts, which could be converted to an STL if you wanted to print the pieces.
That is pretty neat. I can see how that would be a big help for the things I want to scan.
Did you fabricate the scan place using a laser?
Are the protrusions glued on after cutting out the openings or did you ablate the surface?
I designed the plate in Lightburn and cut it with laser cutter (K-40) for the smallest kerf. I then glued all the cut-out pieces to the plate in random locations and orientations, evenly distributed across the surface, then sprayed with Montana Chalk and finally overcoated with a satin sealer. This is the second prototype, the first being a Sculpey disc with random depressions and protrusions. The results were so good, I had to pursue and refine the tool. The material is some kind of polycarbonate, I believe. It was salvaged from a scrapped edge-lit LED TV, so I really have no idea what it is but acrylic will work, as well as almost anything you can cut with a laser. Sebastien Seb, on the Official Revopoint Users group on Facebook has worked out a similar device with a different approach.
Why not use Handy Studio / Revo Studio to merge the parts? It seems like it would be easier.
That is a nice prototype if you don’t want to use markers as they should be used for that kind of scans anyway, if not on the objects then on the plate .
I am using black silicone plate with markes , the scan can’t see the silicon material as it absorb the infrared light . It works very well with all scan modes without the need of separating later the plate from the scanned object as this reminds me of the "Lizard plate " lots of not necessary data
but if this works for you, who am I to judge , we do what works best for us
My goal is to move up to the more powerful software, such as Meshlab, Meshmixer and Blender. I’m looking to gain an education from my tinkering.
That what I am using for my professional projects plus Zbrush …
Thanks for the tip about the silicone plate and markers. I had avoided marker mode because the POP2 was not effective with markers until the release of the Revo Scan app. I’m just a rube when it comes to 3D scanning; I just started in July of 2021, so I’ve been scrambling to catch up with what experts such as you and others on the site already know. It’s been a great ride so far!
By the way, I swiped the idea from the ‘lizard plate’ just to see how well it worked. I also wanted an excuse to have to learn some more sophisticated software outside of Handy or Revo.
As long as it works for you , anything else doesn’t matter ! It is good to be creative , and have some fun on the way . I was doing once a scan of an object that had kind of a powdering paint coating , I did not wanted my tournable to get dirty so I put on top a black trivet silicone mat for protection , to find out later it was completely invisible by the scanner , it also limited the shake of the object especially if it was round and smooth , by accident I found a new tool . The polygon structure helped a lot in stabilization .
If you made a plate with just creases in it and painted it light gray you may have better results , with a different pattern on each angle for better alignment . Or drill in small holes the size of the markers so it can be used in all scan modes , the possibilities are endless .
Thanks for the info. Seems to me I’ve seen those used as ‘spawning mats’ for artificially inseminating raptors, lol.
very handy for many things , and also heat proof but most important invisible to the scan
Hi, @jumbonot would you be kind enough to share your STL file of your plate scan ?
I’ll need to make it more printable, then I’ll upload to sketchfab. I had a terrible time printing it, even on my Prusa.
You can try this version Sebastien Seb designed. Be mindful of his color recommendations. He’s an expert.
There is this one;
who is Sebastien seb ?
