Bio3D Printer

Developed within the laboratory, this 3D printer is dedicated to the study and printing of biocompatible fluids. Its aluminum profile structure provides high rigidity while offering modularity for the addition of new functionalities.

The printer is based on a precise guidance system with ball bushings and ball screws on the X, Y, and Z axes, ensuring high positioning accuracy and excellent repeatability. Motion is driven by NEMA 23 motors, providing sufficient torque for smooth and controlled movements. The working volume is 400 × 500 × 200 mm, allowing the printing of structures of significant size.

In addition to standard three-dimensional movements, the printer incorporates up to six motorized syringe pumps, offering precise control over the dosing and mixing of multiple fluids in real time. A 50 N force sensor monitors mechanical interactions during printing, while a transparent build plate allows observation from all angles. Cameras positioned near the extrusion nozzle provide detailed monitoring of the printing process.

The printer is compatible with standard software such as Pronterface and operates using G-code. Furthermore, several LabVIEW-based programs have been developed for optimizing printing parameters, data acquisition, and detailed analysis of fluid behavior during printing.
