3D printer ALU-MAKER PRUSA STYLE DIRECT TITAN EXTRUDER is the ultimate machine for any 3D printing enthusiast. This device boasts enough strength to function as a CNC engraver-milling machine, thanks to its clever design that incorporates guides with a diameter of 10 mm. The frame is made from high-quality aluminum profile 20 * 40 mm, ensuring durability and stability. Metal elements on the joints measure 3 mm in thickness, while plastic parts are crafted from PETG. The kinematics XY follows a Cartesian system, providing smooth movement and precise control. The mechanics Z feature one motor driving two trapezoidal screws, all synchronized by a belt for seamless operation. Working sizes are impressive at 200 * 200 * 200 mm, making this printer ideal for large-scale projects. The feeding system is DIRECT (extruder - Titan clone), utilizing a 0.4 mm nozzle for fine details. One of the standout features is the table heater, made from aluminum MK3 measuring 220 * 220 mm. This not only keeps the printing surface at optimal temperatures but also adds to the overall aesthetic appeal of the machine. Benefits abound with this printer: • A rigid and strong construction made from aluminum machine profile 20 * 40 mm, secured with metal corners and elements for added stability. • Guides with a diameter of 10 mm that remain straight under their own weight and the weight of the table and carriage, ensuring accurate movement. • The Z-axis flange screws are synchronized by a belt and driven by a single motor, eliminating skewness on the X axis for flawless prints. • An auto-calibration system built on the optical limit switch and SG90 servo drive provides effortless setup and calibration. • A voltage of 24 Volts powers the printer, while 32-bit electronics based on the STM32 microcontroller ensure seamless communication between components. • Silent TMC2208 drivers with interpolation up to 1/256 microstep provide a smooth and quiet printing experience. • The plastic feed is direct, featuring a clone of a Titan gear extruder with a 3:1 ratio of gear teeth, enabling prints with soft flex plastics.
