Unmatched reliability. – Large Format 3D Printing for Medical Applications.
The Form 4BL has been engineered for reliability, ensuring consistent performance for high-volume medical applications. Beta testers and our in-house engineers subjected the Form 4BL to rigorous testing, pushing the printer to its limits with hundreds of prints. Its advanced LFD Print Engine and internal systems work seamlessly to deliver fast, accurate, and dependable results.
Reliability starts at the factory, where each Form 4BL undergoes a meticulous 60-point calibration and quality control inspection. Once in use, smart sensors and advanced systems ensure every print meets the highest standards. Six integrated sensors precisely monitor and control resin temperature, resin level, print forces, and print status. High-speed conduction resin heating, paired with infrared temperature sensing, automatically adjusts resin to an optimal range of 25-45 °C (77-113 °F), tailored to the material.
With the Form 4BL, you can achieve higher throughput, printing larger volumes of medical applications with consistent quality and precision.
