What's your opinion about this 3D scanner?

Hey guys,

What do you think of this 3D scanner?

In my opinion it looks pretty neat, but... I got bad experiences with Kickstarter. (I was an active pledger, here's my profile https://www.kickstarter.com/profile/frederiekpascal)

Not a single hardware was delivered on time (this is easy to be forgiven) but they all had big failures and bugs so I'm very sceptical about Kickstarter nowadays.

But about the 3D scanner, what do you think?

What I like the most about this scanner is the possibility to scan up to 1 square meters.

On a side note. They collected 500.000$ already but the printm3d 3D printer collected 3.5 million $ and that was my worst pledge ever. :)

    I backed it, I was already looking into 3D scanning, and this was the best resolution for a small price.

    and because of the low pricing ( for a comparable scanner), it won't be a huge problem, if they won't deliver.

    backing a kickstarter is always a risk,

    the worst thing about Kickstarter for me is the delivery time, I am almost sure that between now and June next year there will probably be a better scanner available :)

    On the other hand. Because of the low price you can also just wait and see if/what they deliver and get It at the retail price if it's any good.... atm you missed the super early bird anyhow....

    So true Xeno :)


    I was planning on buying a Einscan-S scanner, but the price was a lot more, and was too late to get the early bird special, but I heard they were already working on a more accurate version,

    and will probably be another Kickstarter 4+month project, until then I can experiment with the Eora scanner.

    and maybe the Eora scanner will get even better with the large amount of pledges.

    I don't believe their precision. It's very, very, very unlikely that they will get below the 100 micron precision. I've made a laser scanner with fairly expensive (industrial grade) computer vision cameras and I wasn't able to even get -near- the 100 micron precision. Let alone what they claim to get.

    If you look at the 3D models you can clearly see that they don't reach the 100 micron precision. More like 300-400 micron.

    My first idea for a 3D scanner was actually this, but I scrapped this idea for a number of reasons;

    1. If you move your phone (pressing the interface, getting a call, whatever) you need to recalibrate. Laser scanners can take quite a time to calibrate.

    2. If you want better scans, you need a phone with better camera / lens. Buying a whole new phone just because you want a better scan?

    3. Support -hell- Everyone has a different phone, with different specifications (so they will get different results / issues/ etc). Also note this in buying; Your quality will greatly depend on the quality of your phone!

    4. Laser scanners are known for being slow. Very slow. Both because they need a -lot- of images for a proper scan. Their setup makes it even worse because they use a phone. Edge detection (if you don't want a completely naive solution (Something more complicated then thresholding like Canny or Hough)) is a nightmare. Using the naive approach will work, but only in lab-like conditions (and on certain objects).

    They use a moving laser, which means that for a single snapshot, you will need about 400-500 images. Due to syncing, you can capture about 4-5 frames a second. For a full scan you generaly want about 12 snap shots. This means a full scan will be about 20 (!!) minutes (compared to a projector based setup, that can do the same in 2 minutes).

    They are also using a color camera, which will impact the quality of the model due to the Bayer filter in the camera. This is also why they use a green laser; Color cameras are twice as good with green light as with other colors.

    I do have some good things to say about this though;

    It's cheap for what you get. It's also a step up from regular laser scanners, as the laser can rotate (which increases the number of objects that you can scan).

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
