I was really looking forward to seeing the new Makerbot Digitizer in person at Maker Faire in New York. During the three days I spent at the venue, I was able to stop by the Makerbot booth quite a few times to watch it in operation and discuss the unit both with the Makerbot employees and potential users. Downloading the digitizer documentation from the company website made it possible to ask intelligent questions and to verify key points.
Overall, I left with a fairly positive impression of the digitizer. It works as advertised, is dead simple to use, and produces robust STL files that can be sliced and printed immediately. The unit looks very professional and would look right at home in a engineering lab or design office.
So, what were the downsides? Unfortunately there were a few that will probably keep me from placing an order, at least for the time being.
First is the price. At over USD$1,500, before shipping/handling, it would be hard to justify amortizing the cost over the number of times I could put it to good use for client projects. I'm sure that there are potential customers with a different business model that can use the Makerbot Digitizer, I'm just not in that position right now.
Second is the lack of detail resolution - for me this is a non-starter, and I think it will impact a lot of potential users as well. A good (or bad) example is the puppy model shown above that Makerbot used at the event to show off the digitizer. As you can see from the photo, the puppy has a lot of fine detail, including the hairs on its back. Unfortunately the digitizer can't resolve that level of detail. The STL mesh created by the Makerbot Digitizer application produces smooth surfaces instead.
Third, and this is good news/bad news, the digitizer scan envelope will handle parts that can fit into a cylinder 203 mm in diameter and 203 mm high. While that sounds great, the digitizer can not handle parts that are under 50 mm in diameter or under 50 mm tall. This rules out quite a few of the typical parts I work with regularly. My first thought was to place my parts on a small cylinder, digitize everything, then remove the cylinder by processing the resulting STL data. But the lack of digitizer resolution appears to make that approach impractical.
All things considered, the new Makerbot Digitizer will be attractive to creative artists, some designers, and perhaps consultants, as long as they don't require fine resolution and can afford the price tag.
