plus que mitigé

J'ai essayé plusieurs scan 3d mais pour le moment je ne trouve aucun appareil qui soit efficace, beaucoup de décrochage quand au suivi de l'objet, beaucoup de perte de qualité, je n'ai pas aimé l'utilisation de ce produit qui est pour mon utilisation (modèle d'une 10ene de centimètre) pas efficace

An inexpensive way to get started

The media could not be loaded. I finally pulled the trigger and bought the Creality 3D Scanner "CR-Scan Ferret". I had several projects that I thought this scanner might help me complete more quickly.I am in the habit of using Fusion 360 to produce a model of a part I want to print on my Creality 3D printer (CR-6SE). Usually this involves repeated measurements using a digital caliper and trial prints to get the fit just right. This still leaves the problem of getting the geometry right. If it is something simple, like a cylinder, that's not too difficult. Complex shapes can take hours to dissect and reconstruct using the available tools. This is where the 3D scanner comes in, if it accurately captures the size as well as the geometry of the scanned part.It sounds simple, but obtaining a clean scan of a part is as much an art as a science and can involve expensive equipment, some costing tens of thousands of dollars. That's far out of my budget. To lessen the risk-reward ratio, enter the Ferret. I caught mine on sale in the Sainsmart store on Bolo. It is a great piece of equipment.It has a battery built into the handle, a holder for an Android phone, can be connected to your Windows PC or Mac. It comes with the two cables that your likely to need (one for using your phone, the other for your PC). A word of caution, you'll need a USB 3.0 interface on your PC/Phone if you want this to work. Also, you'll want a fast PC or Phone. I have a Samsung S21, it works great. The faster your phone, the happier you'll be, since it uses the phone's processor in addition to the custom ASIC chip for processing the scanned "dots" into a mesh of triangles. The mesh file is what you import into Fusion 360 or your preferred Mesh editing software (like Blender).My experience was initial frustration at getting a clean scan of the parts I wanted to work with. But, with perseverance, I was able to eventually get some usable scans. My only hint is to not be afraid to try the various settings in the software before you give up. Small objects are best scanned on a turntable (lazy Susan) with the scanner in a fixed location. For larger objects, you will want to mount your phone in the handle, making the scanner portable, and manually passing the scanner around and over the project. It takes a while to get the hang of watching the screen while you scan.Once you complete the scan, the included software allows you to optimize the scan and convert it into a mesh. You also get to add color to the faces. And, you can use the same software to perform simple edits to delete distractions from your scanned models. There are some minor bugs in the software when it comes to editing. In the version I was using when using the rectangular selection mode, it kept resetting to the "lasso mode." It took rechoosing the lasso mode, then the rectangular mode again to do another selection. This was in the PC version of the software. The android version allows you to erase points with your finger on the phone's screen and doesn't have the selection tools.This brings up the point that there are two cameras in this scanner: One is InfraRed, the other is RGB. You'll see both displayed as you scan. You can adjust the intensity of the IR light, which is important if you are trying to scan difficult objects with IR reflective surfaces.Once you get past the frustration of learning a lot in order to be able to do a little, this is a great, inexpensive 3D scanner.The video simply documents the unboxing. Everybody does one of those. 🤣

It good

Don't Waste Your Time

I bought this specifically to scan miniatures. When I hooked it up to my phone, the app would crash every single time before ever starting a single scan. I uninstalled and reinstalled the app and made sure my phone met the prerequisite specs. No luck. When I hooked it up to my computer, the program refused to scan anything. I double-checked to make sure my computer had the requisite 8 gigs of RAM, which it did. No luck. The camera refused to recognize any object besides the platform the figure was on. I adjusted the settings, tried different focal distances, messed with brightness and exposure levels, nothing seemed to get it to work. When I did some troubleshooting online, the official website indicated that the problem might be that the object I was trying to scan might be too small. WTF? I'm not trying to scan a gnat's eyeball. I'm trying to scan a miniature.Luckily I was able to return the scanner for Bolo store credit. Other people seem to have had better luck than I, but $300 is a lot of money to spend to find out.

just ok

Takes some trials and errors to get good results. Still trying to get good results.
