Recently, we published a very nice paper with the team of @daltonlab.bsky.social on volumetric 3D printing. Check out the videos too! Now I brewed the corresponding paperbeer. A Westcoast IPA called Volumetric Vision. It turned out quite alright! advanced.onlinelibrary.wiley.com/doi/abs/10.1...

New publication from the @daltonlab.bsky.social lab, led by Patrick Hall optimizes a unique 3-D manufacturing technique, called volumetric additive manufacturing (VAM) – which has potential applications for implants, hydrogels, and more. Read more: knightcampus.uoregon.edu/printing-fut...

Have been a fanboy of volumetric additive manufacturing (VAM), so it is great to develop and publish this paper doi.org/10.1002/admt.... Since VAM can burn through bioresins, we wanted to develop a low-cost, easy to make formulation with good resolutions and visualization. Enjoy!

With a bluesky account, here is a blast from the past and a test of threads. doi.org/10.1002/adma... changes a fundamental which unlocks geometric freedom for melt electrowriting (MEW). Instead of direct-writing fibers directly on top of each other, the fiber-on-fiber position can be controlled....

A classic melt electrowriting (MEW) video. With a nozzle-collector gap of 3.5 mm, a polycaprolactone melt is extruded to a 5.75kV charged 22G nozzle, thinning out into a fine microfiber. The jet speed is 260mm/min and although the collector speed increases, it never breaks. doi.org/10.1002/admt...

We worked on "taming the jet" for some years, and here is an important milestone in MEW development. Now shown proof of principle, how can we adopt this across all systems, especially the low-cost #MEWron to make them even more powerful! techxplore.com/news/2024-11... www.nature.com/articles/s44...

This is an artifical full-thickness skin that was made in partnership with L'Oreal, published in 2024 here: doi.org/10.1002/adfm... With MEW fibers providing a scaffold for the fibroblasts + an electrospun membrane as an artificial basement membrane, a high quality full-thickness model was created.

My first share comes from alumni Dr Moatazbellah Youssef, who beautifully shows the printing resolutions of MEW. Corbion PC-12, 2.5 micron fibers, 50 micron spacing. I love this image as it shows the difference in scale - the 100 micron scale bar is about as small as one can get from melt extrusion.

Let's start this account with some science from a fanboy - we try to increase volumetric printing resolution AND improve the cost. We did both and now have some PEGDA resins that cost 2c/print. In revision but hopefully soon to be published!
