MakerPi's ComproJet series 3D printers are designed for research applications. Equipped with an industrial-grade piezoelectric nozzle system and a negative pressure system, they effectively prevent ink from dripping or flowing due to gravity or changes in ink cartridge position, making them ideal for high-precision printing of research samples and small parts. Supporting multiple working chamber sizes, including 160*60*60mm, 50*50*50mm, and 30*30*30mm, the printers can meet the diverse needs of research, such as multi-parameter, digital, high-precision, and small-volume printing. Based on Binder Jetting technology, the equipment offers multiple modes, modular design, expandability, high efficiency, high precision, support-free printing, and the ability to produce complex structures. Compatible with a wide range of materials including metals, ceramics, polymers, sand, pharmaceuticals, foo
