Ortur Ortur 4 3D Printer

Main Features
u25cf Overall, Ortur4 is a heavy-duty 3D printer. When designing the structure, it adopts the design of many industrial-grade 3D printers. For example, the chassis (1.0MM sheet metal, other structural parts 3.0MM sheet metal) is especially emphasized. It ensures the stability of the center of gravity when printing at high speed.
u25cf Abandon the ordinary i3 printer with aluminum profile as the XYZ axis design, use the GRS built-in dual-axis linear guide for CNC machines as the XYZ axis, which can support faster printing speed ( can set the i3 machine than the ordinary aluminum profile ). Faster than 2 times the normal printing speed), and higher printing accuracy.
Moreover, the service life of linear guides is much longer than that of ordinary aluminum profiles. Although it is expensive, it is more precise and durable.
u25cf The print head adopts the separate design of the terminal block + bracket + outer casing, which is easy to maintain and repair. Moreover, the print head has been designed to reduce the weight and weighs only about 400 grams. The thermistor and the heating rod are locked in the heating block to prevent the fire from falling off.
u25cf Specially optimized the motherboard MOS tube redundancy design to prevent fire hazards, for example, the hotbed MOS tube supports up to 80A current ( normal motherboards are generally designed only 15-20A current ). Moreover, the large fan is actively cooled to ensure that the motherboard runs stably for a long time.
u25cf Industrial-grade flexible cable for high-power hotbed ( repeated bending up to 10 million times ) to prevent short-circuit fire hazards caused by current overload and line aging.
u25cf Full-chain storage line, beautiful, to prevent the safety hazard caused by messy lines.
u25cf Ortur4 uses the latest Marlin2.0 operating system and is more powerful. And comply with the firmware open source agreement, so that the majority of enthusiasts to deep debug the machine.
u25cf Auto Level + Z Offset = True Auto Leveling. Through the sensor to detect the surface warpage of the hotbed, Ortur4 automatically raises or lowers the Z-axis, and then the distance from the nozzle to each point of the hotbed is always controlled at about 0.1MM, realizing the automatic leveling of the hotbed.
u25cf There is "temperature abnormal protection / Thermal Runaway Protection" function
u25cf There is "breaking detection" function
u25cf There is a "power off and continue to play" function
