Summary of the technology

Pressure measuring device for 3D printing platforms. This device is applicable to various fields using the extrusion of semi-solid masses (tissue bioprinting, food industry, pharmaceutical, ceramics). Its usefulness lies in the fact that it allows continuous control of the pressure applied throughout the printing process, thanks to the instrumentation of the plunger. In this way, quality can be improved and errors can be detected in situ and corrective actions can be applied during the process. By using a strain gauge, the pressure value exerted by the printing platform component on the plunger and, therefore, on the mass to be extruded is obtained. This continuous control makes it possible to characterize the semi-solid mass to be printed and to establish the most suitable printing parameters on the spot, thus making it possible to fully automate the process.

Details of the Technology Offer

Competitive Advantage:

  • It allows continuous rheological characterization of each of the masses used and, consequently, adjustment of the printing parameters before the start of printing.
  • It ensures the flow of the semi-solid mass through the nozzle of the syringe-type dispensing cylinder is constant and, therefore, the extruded volume is correct and, consequently, the dosage.
  • Using customized firmware of the printing platform, continuous process monitoring and in-process corrections can be performed.
  • It allows to detect possible printing errors, such as the existence of air inside the mass that produce errors in the flow (sudden decrease of the printing pressure) or solidification inside the nozzles (sudden increase of the printing pressure). With this, it is possible to discard those three-dimensional forms in which some of these errors have been registered, as well as to ensure the quality by design during the printing process of each dosage form of each batch produced.

About Universidad de La Laguna

The University of La Laguna (ULL) is the oldest institution of higher education learning in the Canary Islands and it is possible to trace its history back more than 200 years. It is a beacon for society in the Canary Islands that, using the Atlantic as a bridge, has stretched out its hand to the rest of the world. Currently, this public institution is home to more than 25,000 individuals who are either students, academic or research staff, or administrative staff and service personnel. The geographical position of Canary Islands in the Atlantic region places them between three continents, which means that, from a strategic point of view, the universities located on the islands are well placed to become important hubs of reference and flagships of knowledge, research and transfer in the Atlantic.
