This Is How Bioprinting Accuracy Could Be Improved

European researchers are touting the first melt electrospinning printer that incorporates the use of bio-inks.

Electrospinning bioprinter regenHU UtrechtThe Swiss biomedical company regenHU says it has accomplished a bioprinting first: an electrospinning device able to handle bio-inks, enabling more accurate bioprinting in the process.

The new machine is being housed at the at the Utrecht Biofabrication Facility, a high-tech facility in the Netherlands created by Utrecht University and the UMC Utrecht in 2013. The machine's melt electrospinning technology is able to create ultrafine and durable fibers, which can be arranged into mesh-like structures that more closely resemble the complex architectures of actual human tissues. The result is the production of tissue structures with more strength, potentially furthering the goal of creating more replacement tissues and even organs that might be placed in people.

Tissue constructs could also be used to study disease, drug efficacy, and toxicity.

"This new device allows us to build complex tissue constructs with high precision, that are mechanically more stable," Jos Malda, associate professor and head of the Utrecht Biofabrication Facility, said in a news release.

"regenHU has a legacy of experience in machine building and this partnership offers strong support for the biofabrication field," Malda said.

The next step is to further test out the regenHU 3-D bioprinter when it comes to generating composite materials, determining the performance of the cells used in the bio-inks.

The new bioprinter is but the latest in a number of recent advances in the field:
