How accurate is 3D scanning?

The accuracy of a 3D scanner really depends on the device itself. And generally, the more expensive the more accurate the results. Most of the scanners we reviewed have adequate accuracy for their target user-base. They carry out both a 3D structure scan and texture scan of an item, along with its color. This is done via either several 360-degree scans on a rotating plate at different angles or by the user themselves if using a handheld scanner.3D scanner accuracy is measured in millimeters and is sometimes called spatial accuracy or special resolution. A good range is considered between 0.5mm and 0.001mm. The smaller the number the better – this measurement refers to how close the scanned model is to the original. I.e. inaccuracies lead to incorrect sizes. An extremely bad scan would produce a blurry blob that could end up several millimeters bigger than the original.Like regular photos and videos, resolution can also play a role in accuracy and detail. Where accuracy is the parent measurement of how correct the scan is overall, when compared to the original, resolution refers to the distance between each scanned point of the object. The higher the resolution the less blurry the surface of the model will be. Think how low-resolution images look pixelated, though not necessarily inaccurate.Many software programs that come with scanners allow you to set the resolution upon saving the model. A particularly high resolution can take up computer resources and may not necessarily result in much difference when 3D printed if the object itself is not that complex, to begin with. Regardless of accuracy and resolution, most devices have trouble with 3D scan textures when it comes to hair because it has such fine detail.

How do I choose a 3D scanner?

Choosing your 3D laser scanning equipment can be confusing, but our 3D scanner reviews and guides will point you in the right direction. You should choose based on your budget and then aim for the scanner with the best accuracy and resolution. Take note of the advantages of handheld scanners vs stationary scanners. Make sure you choose one that works well with the size of objects you wish to scan.

How do I scan something for 3D printing?

The process of scanning a 3D object can vary from scanner to scanner but getting your model ready for 3D printing is mostly a software task.Stationary scanning involves the light source focusing on your object. You will have to move the object into various positions to capture all of the data required for a full 3D model. You can get a 360-degree turntable for this.A handheld 3D scanner allows you to scan over the object yourself with guidance from software and your computer or tablet screen.When scanning is complete you will use your scanner’s software to make any changes and render the model for exporting into a 3D printing format. You can then use 3D printing editing software and slicers to further prepare it for your particular printer.

What is the best 3D laser scanner?

3D laser scanning comes down to accuracy and overall quality, speed, and ease of use. With that in mind, our pick for overall best device that can scan in 3D goes to the Creaform Go!SCAN SPARK. It’s by far the highest quality and most productive option. However, at $35,000 it’s aimed at businesses than the average consumer.An all-rounder that suits both professionals and hobbyists at home is the Shining 3D EinScan Pro 2X Plus – arguably the best handheld 3D scanner we’ve reviewed.At the entry-level, the best 3D scanner is a toss-up between the $399 3D Systems Sense 2 and the $527 Occipital Structure Sensor 3D Scanner MARK II.All of the 3D scanners on our list are worth the money and there are several that just missed the mark that you might want to check out. These include the Atlas 3D Scanner and various Solidworks 3D scanner options, such as the industrial HandyScan 3D the price of which must be quoted. There are also numerous other Go Scan 3D solutions at more affordable prices.
