3D Printing Industry reviews the peel 2 3D Scanner.
Backed by over a decade of research and development in the 3D scanning market, thepeel 23D scanner ispeel 3D’slatest handheld system. Priced at $7,890, the affordable professional-grade machine is intended as an alternative to the pricier industrial devices retailing at $15,000+. As such, it’s suitable for newcomers as well as artists, designers, and engineers looking for a capable piece of kit.
Much like the company’s debutpeel scanner，果皮2由计量专家提供支持Creaform和电子提供商Ametek。与它的前身,它的运行same structured light technology using white LEDs, which is safe for the eyes unlike laser-based scanning technologies. The device features three individual cameras, each bounded by an array of four LEDs and an additional white light projector to deliver full-color, textured 3D scans.
轻量级和人体工程学似乎是这里游戏的名称，因为Peel 2的身体仅重950克，尺寸为150 x 171 x 251mm。这使得扫描仪在较长的扫描过程中在用户手中感到宾至如归，无论是用于演示还是硬核反向工程项目。
该机器通常旨在完成其工作，而无需在扫描范围为0.3m至3m处的靶向点，尽管可能需要它们的表面非常光滑或平坦。虽然果皮2在半透明，完全黑色，镜子，薄壁和头发的物体上也遇到麻烦，但对于其类别和价格范围的任何扫描仪来说，其限制绝对正常。该设备的容量精度高达0.5mm/m，并且能够每秒进行550,000个测量。扫描区域是行业标准380 x 380mm。
校准和设置过程
Packaged in the box is everything you need to start 3D scanning, including a calibration plate, positioning targets, a power supply, and a USB stick containing the manual and software installer.
The calibration process is fairly intuitive, and is recommended (but not essential) before every object scan. Users are required to place the dotted calibration plate on a flat horizontal surface such as a table and scan it in ten different positions. Starting at a perpendicular angle and a distance of approximately 20cm, the scanner is slowly moved away from the plate until it is able to scan the whole thing, taking the necessary snapshots along the way.
Taking around two minutes, this setup stage is quite difficult to mess up but we still thought an absolute beginner could benefit from a quick instructional video. That being said, unlike many other competing scanners, the calibration plate doesn’t need to be slanted and positioned at various obscure angles for the device to get a comprehensive set of readings. This makes the whole experience significantly more user-friendly.
We were also delighted to find that the complementary peel 3D software housed on the USB was easy to get to grips with. The program not only aids users in selecting the optimal scanning parameters such as the resolution, but also guides them through the post-processing stage with clear, defined functions. These include the ability to remove unwanted background elements, plug up holes, and align and merge multiple scans in an assembly.
基准剥离2
是时候看看Peel 2的真正成分了。我们的内部工程师团队将3D扫描仪带来了各种扫描测试的步伐，从艺术作品到功能零件（我们甚至将人类扔进了混合物！）。每项测试中的每项测试均在开放空间中进行三次分辨率（2mm，1mm，0.5mm）进行，并具有大量照明，以获得最佳效果。首先：在卢浮宫中发现了diadumenos的躯干。
Much to our dismay, we didn’t have the original at our disposal so we settled for a white 35cm tall 3D printed replica instead. Even still, the peel 2 delivered on all three scans, each of which took a little under three minutes to complete, and a further three minutes in post-processing. We were impressed by how easy it was to capture the whole thing in a single run and just how little of the background the scanner accidentally caught. Furthermore, we noticed a real difference in quality between the resolutions as 2mm yielded 65,936 faces while 0.5mm yielded a whopping 1,992,116 faces. Overall, a fantastic scan.
接下来是我们的30厘米高的银色喷漆复制品的静水马雕塑。同样，该物体的几何形状很简单，这意味着平均扫描时间不超过三分钟，并在后处理后再进行了两分钟。更敏感的0.5mm分辨率运行捕获了大量不需要的桌子，但是在几秒钟内，Peel 3D软件无法清除。模型的曲线进行了精美的模拟，扫描仪甚至设法跟踪耳朵的缝隙。
Our third object was a white 3D printed Neapolitan Fisherman sculpture – about 50cm tall. We thought this might finally be the test to trip up the peel 2, but the device held its own admirably despite the complexity of the model. His hair, the fine creases of his rags, and even the detailing on the lute resembled the real thing, albeit after some cleaning up. Naturally, the scanning and post-processing times on this model were a little longer than the previous models, averaging five minutes and four minutes respectively. The 2mm scan comprised 177,758 faces while the 0.5mm scan consisted of 2,837,197 faces.
We also compared the 3D scans to the original STL of the part to test the scanner’s dimensional precision. Impressively, each of the scans were within 0.5mm of the STL’s intended dimensions when looking at all points, with an average discrepancy of about 0.25mm. For a handheld scanner at this price point, we deem this highly accurate.
Moving on, we tried our hand at some everyday items around the office. Both the plant and headphones were scanned at a standard resolution of 1mm and produced precise digital copies. A few minutes of clean-up were required for both objects but the scans only took around 3 minutes each and really only struggled in heavily shaded areas.
For the penultimate scanning round, we tested the peel 2 with a helmet and a rear motorbike footpeg hanger, both at a resolution of 1mm. The helmet was generally successful apart from the pitch black padding on the interior, which can be fixed with some additional work in a program such asZBRUSH。The footpeg hanger, on the other hand, came out great. Despite the part being a dark grey, the scanner was able to recreate a solid model. It could certainly be used for reverse engineering purposes or even as a basis for a spare part redesign.
Finally, the human scan. While the final model did end up with plenty of holes, a cleaning session in ZBrush would be enough to make it printable. The scan could also do with the addition of a base to eliminate the messiness of the lower half, although this would be necessary anyway.
但是，当涉及纹理和颜色捕获时，果皮2肯定会表现出色。面孔是可识别的，更细节的细节提供了健康的现实主义。值得注意的是，人类扫描始终是最难正确正确的扫描之一，并且不可避免地需要大量的后处理才能为切片机做好准备。
The verdict
When all is said and done, we have here one of the most cost-effective texture recording 3D scanners on the market. Everything from the hardware to the software – even the way it’s packaged – is great for the price point. The peel team has very thoughtfully streamlined the calibration process, the scanner feels great in the hands, and the software makes cleaning and merging as easy as pie.
While we found that the device wasn’t ideal for objects under 30cm in length, and often lost tracking on exceptionally small, large, or dark surfaces, these are ultimately minor gripes with what is otherwise a fantastic product. The peel 2 is undoubtedly one of the strongest contenders in its class, and makes for a great 3D scanner regardless of the user’s experience level.
