Dremel 3D Idea Builder 3D20 3D Printer

We at are huge fans of all types of 3D printing technology and believe that 3d printers can add a new dimension of learning and creativity to maker projects. We’ve tested a few great 3d printers recently and its exciting to see where the industry has come from in just a short amount of time. There are some great 3D and color label solutions and printers on the market so you’ll be spoilt for choice.

Just recently, we were lucky enough to check out Dremel’s first 3d printer called the Idea Builder (3D20) and in fact it’s also their first additive maker tool. The company is very well known for their hand-held rotary tools which are by design a subtractive piece of equipment.

The Idea Builder was first released to the public in 2014 and it’s a single-extruder printer that weighs around 19 pounds. This current model features a fully enclosed work space which is helpful for stabilizing temperature during printing. This printer doesn’t include a heated build plate so you wont be able to print in ABS. This generally isn’t a problem especially in educational settings where printing with PLA is more than sufficient.

The company states that the Idea Builder has a print resolution of 100 microns in a build volume of 230mm x 150mm x 140mm (9″ x 5.9″ x 5.5″). Listed below are additional features and specs of the 3D20.

The Idea Builder comes with a nice collection of 3d models that are pre-installed and ready to print. We choose to print out the tree frog and the dinosaur.

After a few hours of printing multiple 3d files, we can say that this is a solid 3d printer with exceptional print quality. The only negative that we could find is the fact that prints sometimes don’t stick the first time. After trial and error we found that using painters tape and keeping the build tray perfectly level were essential in getting the prints to adhere.
