well, that’s something, it’s inferior to competitors, but the detail is sufficient for their needs. Thank you for your time.
Considering how small the relief is on this coin, it is superior to all competitors.
he didn’t lose face, that’s for sure, so I calmed down. I don’t have such a coin, maybe I underestimate it. and I noticed that one line gives the best result, so the overpayment is justified.
Consider how our eyes see coins when they are metal and shiny vs a flat 3DScan without a metallic shader .
It was half dollar USA coin
For scanning coins you need at least $20K scanner like Artec Mini with at least 0.01mm accuracy , no other 3D scanner can get you better results and definitely not bellow $2K scanner . That’s where the limit is reached at this point for all handheld 3D scanners.
I have a buddy with a simscan and a leo. He doesn’t like the leo, but the simscan is a serious scanner and does fantastic. It’s in the $30k range tho (I think the new one is $40k), so…
I’m relatively pleased with what we can do under $1.5k, but there’s some features in the simscan I’d really like to see and it’s just software - yea, I know, software development isn’t cheap either.
@PUTV did you see my question on the auto zooming?
As I said earlier, I don’t have a goal to scan coins with this laser, I already have a scanner that can do this. The coin is just a universal reference that allows you to understand the limits of this scanner’s capabilities.
Yes a very good reference , remember a human egg is 0.04 mm
3D scanner with a 0.02mm accuracy is not a microscope , it provide a 0.02mm volume accuracy , it don’t have a 0.02mm resolution to capture human egg size details or half of it, our naked eyes barely can see this kind of details anyway.
The limit of the scanner capabilities is not just the laser mode, the best results are provided with a single shot Auto mode that have a slightly better results because the scanning is stable condition and blue light technology that currently is the best to archive maximum accuracy , handheld scanning can’t provide the maximum results due to shaking of the hand.
Here’s a tiny little switch that’s black with shiny metal prongs.
‘Y, single line on the top and cross line on the bottom. Max settings.
Single line with the ‘Y, gets really noisy around the prongs.
Metro X, cross line.
I know , I have the same issue with it , it keeps zooming out . I will need to request this feature because right now it will go back automatic .
Try to use the zoom in Auto mode on the camera , it suppose to keep the zoom in the viewport steady as well.
Tried a Lego Jet with white, blue and red bricks. The ‘Y is blind to the red bricks in normal mode (no surprise), but much to my surprise gets the blue bricks, where the ‘X was blind to the red and blue bricks.
The canopy is smoke/clear and the ‘Y didn’t do that well either.
I tried it in Black mode too and it lost tracking and f’d up…I thought that problem was solved as I haven’t seen it skip track in a while, but i guess the problem still exists. Also the weird lines in it are sub optimal.
I think I’ll do a production item next.
WOW, this was fast, way faster than the ‘X. Cross line, default res and Black. It came out really nicely. I make the baseplate for it and need a dummy (non functional, no moving parts) for practice. I think I can print right off this scan.
I remember the other 3D scan you did of this object, really nice result .
The X and Y should not be blind to the blue color since it do not absorb blue laser light . But because it has a multiple colors , it is hard to setup the proper brightness to make them all visible. Usually I scan first the most lightest color then after that increase the laser brightness and finishing the most difficult one. This way the surface is not rigged on the lighter surface and less micro reflections ( noises )
I sent the watertight model to the printer to use as a dummy. 13hrs and .4 kg of material later and it’ll be done.
2 of my printers are running jobs that started with the Metro scanners. Need to get the 3rd printer running too, but it’s getting upgrades that also started with the Metro scanner. Then I’ll be an electricity gobblin fool.
Take a picture of your dummy with all the supports still attached (before you remove from the build plate). I want to see how you set it on the build plate–just want to see if I would have done it the same way.
Thanks,
Bruce
