# Breakthrough in Bioprinting Technology Using Modified 3D Printer

A breakthrough in bioprinting technology has been announced by researchers at the University of Rochester, who have successfully modified a standard $450 3D printer to create living materials with over 100 layers.

The team, led by Professor Anne S. Meyer, aimed to make DIY bioprinters affordable and accessible to scientists worldwide by using inexpensive parts that are easily obtainable. According to Meyer, the goal is to enable other researchers to create these bioprinters in their own labs without breaking the bank.

The modified 3D printer replaces the plastic filament extruder with a syringe pump that dispenses bio-ink, a specialized formula combining living cells and a polymer solution. This unique mixture hardens into a gel once printed, setting it apart from traditional bioprinted materials.

Using this low-cost setup, researchers can create living tissues with precise control over cell types and final shape. The possibilities are vast, ranging from cleaning up contaminated water to breaking down waste materials like plastic.

The team's innovative approach addresses the significant drawback of current 3D bioprinters: their high cost and tendency to collapse before setting.

The customized bioprinter's syringe is capable of both extrusion and retraction, preventing unwanted oozing at the edges of printed structures.

This innovative setup allows for the creation of crisp shapes with well-defined edges, a significant improvement over previous DIY 3D bioprinters. The cost of this upgraded printer was remarkably low, thanks to its components being easily sourced from various suppliers. As a result, other labs can now build their own version of the printer and syringe pump.

The new DIY bioprinter has expanded the possibilities for printing living structures by allowing for more than 100 layers. In contrast, previous versions were limited to fewer than 20 layers. This significant increase in complexity and height enables researchers to create hollow cavities within printed structures.

The upgraded printer's capabilities open up new avenues for creating structures with a high surface-to-volume ratio. This allows embedded bacteria to efficiently receive signals or nutrients from their surroundings and excrete useful products at an accelerated rate.

To facilitate the printing process, researchers developed a support gel called slurry that holds up bio-ink and helps it solidify quickly at any height. Two types of slurry were created: one for easy removal of the print and another designed for incubation that allows microbes in the bioprints to remain alive for four or more weeks.

The versatility of this new slurry is vast, enabling researchers to create engineered biofilm materials that can mimic the characteristics of real-world biofilms or possess enhanced mechanical properties.

Researchers can now test and study these artificially created biofilms in a controlled environment, gaining valuable insights into their behavior and interactions with surfaces. This breakthrough has significant implications for various fields, including medicine, where understanding biofilms is crucial for developing effective treatments.

The creation of living materials with more than 100 layers using this modified $450 3D printer marks a major advancement in bioprinting technology, opening up new avenues for research and development in fields that rely on complex structures.
