Building a biomemetic tissue requires a printing process that is both ultrafast and high-resolution.
High resolution and small feature sizes (5-10 microns) is necessary to recreate a functional tissue; even a factor of 10x difference in vascular size requires significant alterations in the structure, function, and size of a bioprinted tissue. Our technology makes the recreation of a physiologically matched organ possible.
AND LIVING TISSUE
Prellis developed the first high-resolution laser projection technology to print ultrafine tissue scaffolds from biocompatible materials at speeds >100x faster than the industry standard.
Speed is critical for organ engineering. The finer the feature size, the longer a printing process takes. As a print scales in three dimensions, the time to build a tissue becomes prohibitively long, requiring years to build a single human-like tissue scaffold. Prellis has solved the problem of coupled speed and resolution by using holographic image projection to simultaneously print up to 2.5 million voxels (points of light) per second to construct ultrafine featured biomimetic tissue scaffolds.
