Correction scan 3D

Bonsoir à tous !

Je viens vers vous car dans le domaine du scan 3d je suis un peu pommé (voir beaucoup). Je pense que certains d'entre vous seront bien plus calés que moi dans le domaine et pourront m'aider :)

J'expose mon soucis !

Lorsque l'on scan en 3D nos modèles dentaire on obtient un très joli scan (scan pro de 3M prévu pour) mais les artefacts sont monstrueux et je parle même pas du maillage !

J'ai beaucoup entendu parler de netfabb pour corriger une partie or lui même n'y arrive pas (il me retourne une erreur !) :/ J'ai voulu tester meshlab mais quand je vois tout le boulot qu'il faudrait faire sur chaque modèle (10 par jour) waaah... et puis je comprends pas grand chose au logiciel en question ^^

Certains pourraient-ils m'aider dans une meilleure compréhension du soucis et m'orienter vers une solution ou plus possible ?

Encore merci à tous !


Nb. voici un scan en question histoire de voir à quoi ça ressemble:

    J'avais un scan tout pourri j'ai utilisé meshmixer pour le nettoyer et le corriger. Y a une fonction Make Solid qui fonctionne pas mal mais c'est pas forcément toujours précis (en fonction de la qualité du scan)

    Ouep Comme dit Didier, Meshmixer et Meshlab fonctionnent bien sur ton fichier.

    Tu veux juste boucher les trous dans les dents et faire un petit détartrage de polygones ?


    Oui c'est exactement ça ! Afin de rendre plat le dessous du modèle pour pouvoir l'imprimer biens-sûr :)

    super pour reparer les modeles, gratuit, online.


    Netfabb n'y arrive justement pas ! Essaye avec mon fichier et tu verras l'erreur qu'il te retourne :/

    Je vais aller tester Meshmixer :)

    Merci à vous ! Je reviens vite ;)

    My french is quite bad, but i could understand enough of it to try and and help you.

    You could also try meshlab. This has quite a few filters to improve the quality of meshes. Most notably the poisson solver; this should guarentee watertight meshes. I've tried it with an octree depth of 8 and a solver divide of 8, which gives pretty decent results. If you want to print this, you can use cura to 'sink' it into the platform (so the bottom is flat)

    @nallath Any problem if we speek english. I would like try meshlab but I need to find a very good tuto to do what I want with. For the momenI don't understand any thing of this soft ^^

    But my biggest problem is, how many time take this "manually" correction of one scan on meshlab ?

    Thanks a lot

      • 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!
          • Thanks

      • 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.
