Dremel's second generation model of their Idea Builder line, the 3D40 is a solid, fairly priced, plug and play printer, noted for its reliability, ease of use, and positioning towards use in an educational setting. In fact, one could make a very solid argument that Dremel, as a business, is doing exactly what it will take to launch 3D printing forward on a wider scale: through their various initiatives and partnerships, Dremel is introducing this new and still fairly complex technology to an entirely new generation of potential future users — quite a step up from the "if we build it, they will come" approach favored by so many of their competitors.
As a standalone printer, apart from all of the advantages conferred onto its use in educational settings, the Idea Builder 3D40 is easy to use and reliable. Assisted leveling helps ease the difficulties of calibration, one of the harder parts of operating a printer. The touch screen interface is easy to navigate, and the accompanying flash drive comes pre-loaded with some ready-to-print STL files — so you can get your feet wet without the daunting task of deciding from anything what your first print will be. And if the rare technical failure is experienced, Dremel technicians are always available to field your call, assuage your concerns, and deliver you a solution (perhaps, if in an educational setting, such a call would be a great learning opportunity for a tinkering student to make themselves).
Dremel makes serious efforts to connect their products with their desired audience of educational settings. These efforts include partnering with the PD Learning Network to create a 3D printing course geared towards K-12 educators, massive Idea Builder giveaways to participating schools on social media (2 printers to top 50 competing schools in their last such giveaway!), and a set of curriculum-based lesson plans aimed specifically at integrating 3D printers into a good STEM education. These forward-thinking drives are exactly what is needed to advance such a development as 3D printing: complex and hard to get into, but offering virtually unlimited long run potential if the interest can be queued up and proper instruction given at the first vital stages of the learning experience.
This printer gives great quality prints, but I have had a lot of trouble with many different issues.
The printer itself is well built and extremely reliable. We have had very few failed prints and the leveling of the print bed is extremely easy.
Dremel is known for easy-to-use and useful hobbyist tools but it has lacking some features that the more advanced enthusiast would desire.
The software you download from the Dremel site is extremely user friendly and simple to use. I've been printing without stopping since I got it.
