Like we said, even before you power up the Digitizer, it already puts a smile on your face. The simple black plastic body definitely isn't going to win any design awards and it doesn't exactly ooze luxury, but it is playfully futuristic, in a way reminiscent of early '90s children's toys. It's angular, understated and utilitarian, which isn't necessarily a bad thing. Oddly there is some assembly required: the four rubber feet used to keep it from slipping about a desktop come packaged in a small zip-top bag. After you pop those little rubber guys in place, you're free to plug the Digitizer into an outlet and your computer's USB port and get going... with the calibration that is.
Just like the replicator before it, the Digitizer needs to be carefully calibrated for effective use. And, while the process is much quicker and less labor intensive (no constant adjusting of knobs here), the scanner actually appears to be much more sensitive and needs more frequent tune ups. MakerBot's instructions call for recalibrating every 20 scans or once a week, but we needed to run the calibration three times in the course of a week and never topped 10 scans before our results started getting funny. But, more on that later.
The calibration process itself involves making sure the filter is placed over the 1.3-megapixel camera at the center of the raised bar on one side, then placing a special calibration tool on the turntable. Over the course of about 10 minutes you'll be asked to place the checkered, three-sided calibration tool in a variety of poses while the MakerWare app takes measurements from the camera and dual lasers that flank it. From there scanning is a relatively straight forward process, so long as you follow MakerBot's words of advice. Those words: avoid anything dark, shiny, transparent, fury or larger than eight inches in any direction. If you do, the results will be decent, if hardly mind blowing. MakerBot's example scan of a gnome figurine is quite a bit clearer than any results we managed to get. Even when we scanned a plain white Munny figure, the model displayed some weird pitting, misshapen ears and webbing between the arms and the body.
The act of scanning an object is about as simple as it gets. Make sure the filter is over the camera (this is super important), place your target in the middle of the turntable and click start scan. The only setting to mess with is adjusting the shade of the object your scanning, between light, medium and dark. Then you've just got to find something to do for about 10-12 minutes and stay out of the way of the scanner. Don't touch it, bump it or even get too close to it. That's not only to avoid screwing up your virtual model, but also to protect your eyes from the laser line generators. Sure, they're listed as eye-safe, but they're still pretty unpleasant when they hit your retinas.
Once that's done, you simply crop your model to the proper height and upload your scan to Thingiverse, if you'd like. You can back up your scans privately or share them for others to download, manipulate and print on their own. MakerWare will walk you through sliding the filter off the camera to take a snapshot of your real world target, ask you to log in and upload the scan.
It all seems simple enough, until you hit a snag. Once one thing goes wrong, the whole shebang has a sort of meltdown. When MakerBot says that dark, transparent or shiny objects are not ideally suited to scanning, what they really mean is: don't even bother. (Though, we've been told you can dull the luster on shiny items with cornstarch and achieve better results.) We tried to scan a pair of matte black sunglasses with particularly dark gray lenses, and ended up with something you'd find MoMA. We immediately saw a problem when the scan started updating live on our iMac, so we cancelled it. When we clicked retry the scan simply failed and we had to restart the scanning service to get MakerWare back up and running. This happened almost anytime we had to cancel a scan or put the computer to sleep. Even after we recalibrated the Digitizer the results were still a mess. While we were able to make out the general outline of a pair of glasses, it was buried in a sea of seemingly random shapes. Even some good, usable scans turned up weird anomalies, such as the UFO hovering above Om Nom you see above.
The Digitizer is fun and potentially ground breaking, but it's also occasionally frustrating. The device is as small and unobtrusive as you can reasonably expect and, in the grand scheme of things, not particularly expensive. MakerBot has even succeeded at making the scanner damn-near fool-proof. But, it's hardly perfect. Results are sort of a mixed bag and, if you stray from the suggested ideal conditions, chances are you'll get something completely unusable. It shouldn't come as any surprise that the Digitizer isn't practical for the average user -- it's clearly targeted at tinkerers and DIY enthusiasts. But that doesn't mean things will always be that way. Call us optimistic, but we choose to see the Digitizer as the first tentative step towards something revolutionary.
