Plastic 3D printing has allowed rapid prototyping to take on a whole new meaning. Scale mock-ups can be created with incredible precision and reproducibility without needing to retool large-scale manufacturing operations. It’s a potential game-changer in terms of cutting shipping and storage costs - something that could dramatically offset the higher per unit cost of manufacturing with 3D printing.
So now we come back to the life sciences. Can we expect a similar trajectory for 3D bioprinting as we’ve seen for 3D plastic printing? Maybe. We definitely believe it can!
A complex 3D construct for cartilage, for example, with interconnected pores and multiple different types of layers would normally take days to make piece by piece. A bioprinter could, perhaps, do it all in a fraction of that time.
A high school biology lesson on diffusion across a membrane takes on a whole new meaning as students observe a colored dye flowing through a 3D gel with an embedded membrane structure which they made as opposed to looking at a 2D picture in a book.
Trying to decide how a liver cell behaves in the body’s 3D microenvironment now becomes a more manageable task because you can actually print a whole liver sub-unit, label different structures radioactively or with dyes and follow everything in 3D.
To understand our highly complex bodies, we’ve looked at simple organisms such as a planarian to understand how development works. Let’s add a powerful tool to combine that critical understanding of development with the ability to recreate it in an environment that mimics nature much more closely than ever before. Let’s take the lessons we have learned about functionality and easy access from personal computers, smartphones, and plastic 3D printing and apply them to tackle some of the biggest problems we face as a species - those of our health and fitness.
