Creality has launched a new large format FDM / FFF 3D printer – CR-M4. The device is presented as a quasi-industrial class equipment, equipped with network functions for the creation of 3D printer farms. The working area of the CR-M4 is 450 x 450 x 470 mm, and the stability of the structure is to be ensured by the double Z axis and two supporting rods, which form a rigid triangle stabilizing the upper frame of the device. Each Z-axis is driven by an independent motor for precise and accurate movement. The cost of a new 3D printer is EUR 1,359.
In addition to the rigid triangular frame, the CR-M4 is also equipped with dual Y-axis linear rails to ensure the quality of the models. The Y-axis double linear rails are milled from high-quality bearing steel, which greatly improves the accuracy of the Y-axis motion and increases resistance to wear, backlash and heavy loads. According to Creality, the new linear rail system made using CNC machining is much more reliable and durable than V-slot rails. Additionally, the Y-axis gearbox is driven by a powerful precision stepper motor for increased precision and smooth movement. Test results conducted at Creality Lab showed that the stepper motor can print continuously and stably for 720 hours (30 days).
The CR-M4 is customized to connect multiple copies to a LAN via Creality Print to create your own centrally controlled 3D printer farm. Users can also print and monitor remotely from the Creality Cloud app or web when the CR-M4 is connected to the internet. Within a 3D printer farm, devices can produce the same model with a single command from Creality Print or Creality Cloud Web. The CR-M4 can also print directly from a flash drive or from a computer via a USB-C, RJ45 cable as well as via Wi-Fi.
The 3D printer is equipped with Creality’s proprietary “Sprite” direct extruder, known from the previously released models of the Ender and CR series 3D printers. Sprite has double gears with a ratio of 1:3.5, which provides a uniform extrusion force of 80N. With an upgraded nozzle and 50W heater cartridge, the high flow hotend can completely process high temperature filaments at temperatures as high as 300°C like polycarbonate or nylon. Of course, CR-M4 perfectly copes with the most popular filaments such as PLA, ABS or PETG. As standard, the 3D printer is equipped with a print head with a diameter of 0.4 mm, but it can be replaced with larger ones: 0.6 mm and 0.8 mm.
The CR-M4 has fully automatic table leveling using CR Touch – a system of probing 25 points on the work table and Z axis shift with an accuracy of 0.05 mm. The build platform consists of 4 different tiers. The top coating provides strong adhesion, and the flexible spring steel sheet makes it easy to remove large models without deformation. The magnetic base and two pins allow for quick snapping and quick removal of the plate from the 3D printer structure. The final layer is a 470 x 470 mm aluminum alloy heated bed, which has been tested by Creality Lab to heat up to 60°C in 160 seconds.
The 3D printer is equipped with an industrial control power supply with a power of 800W, which ensures safe and stable operation. The power supply is compatible with 100V-240V and can filter voltage fluctuations and electromagnetic interference and prevent short circuits, overloads, overvoltages and overheating of the 3D printer.
To operate the 3D printer, a 4.3 inch color screen with simple and responsive touch controls is provided. The screen supports model preview and temperature PID tuning. The screen will turn off after five minutes of inactivity. Thanks to the silent motherboard, the noise from the CR-M4 at a distance of 1 m is 50 decibels, which is equivalent to the sound of indoor conversations.
