Dremel Digilab 3D 20 Review

The tool manufacturer Dremel has had 3D printers in its range for some time. The Idea Builder 3D20 does very well in the test, but it is expensive.

The Dremel printer arrives at the customer neatly packaged and well protected. In contrast to all previously tested devices, the 3D20 has a closed installation space. The print bed and any technology are hidden inside the gray plastic housing. A plexiglass door on the front allows a view of the illuminated interior and access to the prints. That looks neat and protects the components from dirt. Although Dremel also advertises noise reduction, this was not confirmed in the test. In order to still have easy access to all components, the cover and parts of the side panel can be removed in a few simple steps. This is very useful, for example, when cleaning the print nozzle.

The SD card slot and the USB port are on the right side of the case. There is a touch-sensitive 3.5-inch IPS display for operation and status display, which is located at the bottom right on the front.

Operation via the touchscreen is simple and intuitive.

The printhead hangs on the X-axis. This is connected to the Y-axis on both sides. The Z-axis does not move the print head, instead the moving print platform moves up and down. The entire construction is torsion-resistant, looks high-quality and very stable.

If you look at the print head, you will notice an additional, second fan. All other printers that we have tested so far, such as the Renkforce RF100 or the Wanhao i3 Mini , did not have it. It is responsible for cooling the printed parts, which is particularly useful when printing PLA. The printed filament cools down faster, which ensures better results when printing overhangs, for example.

There are three knurled screws available for calibrating the printing substrate. The manual adjustment of the distance between the print head and the print bed is uncomplicated, but absolutely necessary. If the distance is not set correctly, the filament will not hold on to the printing surface. An automatic calibration like the Davinci Mini w + (test report)there is not any. The processing of all components of the printer is very high quality. The print bed consists of a solid, transparent plastic plate. This is not permanently installed, but simply fixed with plastic clips and can be easily removed. This is practical, because removing finished prints from the print bed is much more convenient outside of the housing. Since the filament is sometimes very firmly connected to the substrate, there is otherwise the risk of damaging the printer’s mechanics.

The scope of delivery includes the printer with power and USB cables, a plastic spatula, a tool for cleaning the print nozzle and a 250 gram roll of white PLA filament. A memory card with 3D models and the Dremel slicing software is also included. The finished print templates include, for example, a chess figure, a dinosaur head or a vase.

Commissioning the printer is straightforward. After unpacking, only the styrofoam parts of the transport lock and a sticker are removed from the print bed. After unpacking the filament roll, it is placed on a plug-in holder inside the housing. After plugging in, the print bed is calibrated by hand and the filament is inserted.

With the 3D20, it takes less than 15 minutes from opening the package to the first test print. The result, the chess piece from the memory card, is not quite perfect, but it is impressive. Only the surface structure can be improved, since minimal gaps can be seen.

The adhesion to the print bed is also convincingly reliable. The object holds very well during printing – but with a little force and the help of a spatula, it is easy to get down.

With the next print job, the little boat (Benchy3D) that we use as a stress test for printers, the printer does very well. The surface structure can also be improved here in places, but that is only a matter of the settings in the software. In our case, increasing the thickness of the top print layer helps. Numerous instructions from the Internet explain which tricks are necessary for the various errors in the print image. A good example with common mistakes and solutions can be found here .

The white PLA boat is printed much more neatly than the one made of wood filament.

In the test, the printing speed of the 3D20 was impressive. Despite the high speed, the surfaces of the printout are very homogeneous and clean. Here the manufacturer has done a really good job. Even large objects or prints with wood filament work right away and can easily keep up with the results of the Renkforce RF100 and the Duplicator i3 Mini .

The 3D20 works with filaments from any manufacturer. Other printers, such as the Davinci Mini w +, only accept consumables from their own company due to an NFC tag attached to the filament roll. Foreign filaments often do not fit inside the Dremel printer due to the roll size. In practice, this is not a problem: external brackets are available as free 3D printing templates .

The in-house consumables fit perfectly into the housing, but they are about twice to three times as expensive as filaments from other manufacturers. Officially, the printer is only designed for processing PLA. That is a shame, the closed installation space would have been excellent for processing ABS. However, this is not possible due to the lack of a heating bed. ( Overview of standard filaments , overview of exotic filaments ). Retrofitting a heating bed is theoretically possible, but there are no ready-made retrofit sets. If you want to print materials such as ABS or nylon, you can alternatively look at the Dremel 3D45 printer. This has a heated bed and WiFi, but costs almost twice as much.
