3D DIY Bio-printer: Bioengineering project

3D bio-printers can be used to print biological materials such as gels, proteins and cells. Inspired by the BioCurious team, our group at Nanyang Technological University (NTU) Singapore assembled a 3D DIY bio-printer and explored the possibility of printing mammalian cells.

First, we assembled the printer following the manual from Instructables.

This is the DIY 3D bio-printer created by team at NTU Singapore.

We tested the bio-printer for printing alginate gels. Calcium chloride solution was dropped onto a culture dish containing 1%, 2%, 3% and 4% sodium alginate solution. We found that 1.5-2.0% alginate worked best in providing most consistency in printing. The picture below shows a test print using ink versus alginate hydrogel.

Finally we showed that 3D gels could be printed using this DIY bio-printer platform, the picture below shows a printed gel with 200 layers of printing. And we also printed mammalian cells (HS5 stromal cells) using this DIY 3D bio-printer in alginate hdyrogel…

Discovery Day @Sandpiper Elementary School

We had a fun-filled day at Discovery Day (Jun 4) in Sandpiper Elementary School this week. The kids were so excited to learn about 3D printing and start creating their own 3D models. We introduced them to Blokify, an iPad program for 3D modeling. It is easy to use and fun for kids - they simply loved it! Thanks Blokify - we love your app!!!

Here are some pictures we like to share with all of you from that day. See what the kids have created that day and only within an hour. It's amazing and so much fun!!!

We thank the Discovery Day team led by Rahila and Pushpa for giving us a chance to host this event at Sandpiper Elementary. Great job on Discovery Day.
