Portuguese 3D printer startup Blocks will release a new model, the Blocks R21, which is due to hit the market in September. Fortunately, we were able to test the device already in its final version, which showed an impressive evolution compared to the previously tested model. One MKII.
This new printer features an all-aluminum construction, an LCD touch panel that allows you to control all printer settings. Among them is the calibration of the print tray, which, in addition to heating, has a metal coating with a texture that greatly contributes to the adhesion of the filament during printing.
Another important detail is the integration of all the main printing elements in one module, such as a two-block extruder and a hot end. The latter has a threaded screw for quick replacement, which allows you to replace the module with another one with a nozzle that is compatible with a particular type of filament. The variation can be from 0.2 to 1 mm – the hot end supplied with the printer is equipped with a 0.4 mm nozzle. This is to provide better print quality based on filament type, from traditional PLA to ABS, Flex, PETG, nylon, fiberglass, carbon fiber reinforced PET, PLA with metal or wood.
In terms of use, the Blocks R21 couldn’t be simpler and more intuitive thanks to the aforementioned LCD touch screen and a new tray that is easy to calibrate and requires a minimum amount of glue liquid (varnish). The fact that it uses an almost closed rigid construction, together with the integration of all units into a single module, made it feel quieter: it was even the quietest I have tested to date. Blocks R21 is priced to be considered “premium” and is available in a basic version, already with all the accessories you need to get started printing right away. However, we can buy it with an optional connection kit which, while pushing the price up to a less than pleasant €1,800, adds a Wi-Fi controller, webcam and temperature sensor so you can monitor print status remotely.
