I finally got my hands on the hardware needed to run a proper scantech simscan test in a real-world workshop setting rather than just reading about it in a brochure. If you've been following the 3D scanning world lately, you know that things are getting smaller, faster, and way more accurate, but there's always a bit of skepticism when a device claims to be "palm-sized" while promising metrology-grade results. Most of the high-end scanners I've used in the past feel like you're lugging around a heavy DSLR or a chunky power tool, so the idea of something that fits in one hand is pretty intriguing.
The goal of this scantech simscan test was simple: see if this tiny device could actually handle complex geometries and shiny surfaces without making me want to pull my hair out. I didn't want to test it on a perfect, matte-white cube. Instead, I grabbed an old, slightly greasy engine component with plenty of deep recesses and tight corners—the kind of stuff that usually gives optical scanners a hard time.
First Impressions Out of the Box
When you first see the SIMSCAN, it's honestly a bit jarring. It looks more like a high-tech shaver than a piece of precision measurement equipment. But as soon as you pick it up, the weight tells a different story. It's got that dense, metallic feel that suggests there's a lot of high-end glass and electronics packed inside.
One of the first things I noticed during the setup for the scantech simscan test was the build quality. The housing is made of aerospace-grade aluminum, which is a nice touch because workshops aren't exactly gentle environments. It's designed to be used with one hand, leaving your other hand free to move the part or steady yourself. This might seem like a small detail, but if you've ever spent four hours scanning a large object with a two-pound scanner, your wrists will definitely appreciate the difference.
Setting Up for the Scan
Setting up for the scantech simscan test was surprisingly straightforward. Like most professional-grade scanners, it uses markers (those little reflective dots) to keep its place in 3D space. I slapped a few dozen markers on the engine part and a few on the table around it.
I've used scanners before where the software felt like it was designed in the 90s, but the interface here is pretty clean. Once I plugged it in and let the lasers warm up for a minute, I was ready to go. Calibration took about sixty seconds—just a few passes over a calibration plate to make sure everything was aligned. I've seen some people skip this step, but if you're looking for microns, you really can't afford to be lazy here.
The Performance in Tight Spaces
This is where the scantech simscan test really gets interesting. The biggest selling point of this specific model is the "shorter distance" between its cameras. In the 3D scanning world, if the cameras are too far apart, you can't see into deep holes or narrow gaps because one camera gets blocked by the edge of the hole.
As I moved the SIMSCAN over the intake ports of the engine block, I was genuinely impressed. I didn't have to do the usual "scanning dance"—that awkward tilting and twisting you usually have to do to get a signal. The blue lasers stayed locked on, and the mesh started building on the screen in real-time. It felt very fluid. There's a certain satisfaction in seeing a digital twin of a physical object appear on your monitor as you "paint" it with light.
Dealing with Shiny and Dark Surfaces
We've all been there—you try to scan something shiny, and the software just sees a giant blob of white noise. For this part of the scantech simscan test, I intentionally didn't use any matting spray on the machined surfaces of the block. I wanted to see how the blue laser technology handled the reflections.
The SIMSCAN uses multiple laser modes. For the general bulk of the part, I used the cross-laser mode which covers a lot of ground quickly. When I got to the shiny, machined faces where the gasket sits, I switched to the single-line mode. This concentrates the power and helps the cameras pick up the reflection more accurately. It handled the glare much better than I expected. Don't get me wrong, if you're trying to scan a chrome bumper, you're still probably going to want some spray, but for raw machined steel or aluminum, it held its own.
Software and Data Processing
A scanner is only as good as the software that interprets the light, and during the scantech simscan test, the ScanViewer software did the heavy lifting. One thing I've noticed with cheaper scanners is that the software tends to lag or crash when the file size gets too big. The SIMSCAN generates a lot of data very quickly because it has such a high frame rate.
Luckily, the software seems optimized for it. I was able to hole-fill, smooth out some of the noise, and decimate the mesh (reduce the polygon count) without the program hanging. The "intelligent optimization" feature is actually pretty smart—it keeps the detail where you need it (like on sharp edges or small holes) and simplifies the flat areas where you don't need millions of triangles.
Accuracy and Metrology
I know a lot of people care about the numbers, so I checked the specs against my results. Scantech claims an accuracy of up to 0.020 mm. While I don't have a laboratory-grade CMM (Coordinate Measuring Machine) to verify that down to the last micron, I did compare some measurements taken with digital calipers against the digital model created during the scantech simscan test.
The distances between bolt holes were spot on. When I overlaid the scan onto the original CAD file of the part, the heat map showed very little deviation. For anyone doing reverse engineering or quality control, this level of precision in such a small package is a bit of a game-changer. You can take the scanner to the part rather than dragging a 500-pound part to a measurement room.
The Ergonomics of Long Sessions
I spent about three hours total running this scantech simscan test, including different parts and various settings. Usually, by the end of a session like that, my arm is vibrating from the weight and the slight hum of the device. Because the SIMSCAN is so light, I didn't feel that fatigue.
The haptic feedback is another nice touch. The device vibrates slightly to let you know if you're too close or too far from the object. It's much better than having to constantly look back at the laptop screen to check your distance. You can just focus on the part and let your hand adjust based on the "feel" of the scan.
Real-World Limitations
No tool is perfect, and I found a few things during the scantech simscan test that are worth noting. First, because it's so small, the field of view is also smaller than some of the larger "handheld" units. This means if you're trying to scan an entire car, it's going to take you longer than if you were using a larger device like the KSCAN.
Also, the cable is a bit stiff. It's a high-quality data cable, but because the scanner itself is so light, the cable can sometimes feel like it's pulling on your hand. It's a minor gripe, but something you notice when you're trying to do very delicate movements in a cramped engine bay.
Who is This Actually For?
After wrapping up the scantech simscan test, I started thinking about who would actually benefit most from this. If you're a hobbyist scanning figurines for 3D printing, this is probably overkill (and out of the price range). However, for an engineer in an automotive plant or an aerospace technician who needs to inspect parts inside a fuselage, it's a no-brainer.
The ability to reach into spots where a traditional scanner simply won't fit is the real value here. It bridges the gap between those super-accurate stationary scanners and the more portable but less precise "hobbyist" tools.
Final Thoughts on the SIMSCAN
To be honest, I went into this scantech simscan test expecting it to be a bit of a gimmick—another company trying to make things small just for the sake of it. But after using it, I get it. The portability isn't just about making it easier to carry; it's about making it possible to scan things that were previously unscannable due to space constraints.
It's fast, the software is reliable, and the accuracy is exactly where it needs to be for professional work. If you have the budget and you're tired of fighting with bulky equipment in tight spaces, this little guy is definitely worth a look. It's one of those rare cases where the tech actually lives up to the marketing hype.
