Bioprinter Extruder Design
By Ali Etezadkhah – Project Manager When we started working on the Bioprinter, one of our main challenges was to redesign a new extruder mechanism. While the idea of using a syringe and a linear actuator to dispense the printing gel was good, the execution needed much improvement. The original extruder used a small syringe […]
Bioprinter “Ink”
Above, Agar plate with growing cells By Ali Etezadkhah, Project Manager To grow and take shape, cells need a skeleton or scaffold to attach to. They also need access to nutrients to survive. There are many different types of cell growth media and they range from pure liquid to a solid gel. Most people have […]
Original Mendel Model
By Anh Nguyen ADVANTAGES: Simple to build. There are a lot of information, manual and video to help building. http://reprap.org/wiki/Mendel_Build_Manual http://www.youtube.com/watch?v=mpOZ1GNZmmU Big print area, smaller machine footprint Light and portable The price is reasonable and within budget. DISADVANTAGES: The frame and the joint junctions are not stable in the x-axis. The head […]

Laur3k-3D Printer by OpenBuilds
By Omair Tariq (Information on the Laur3K can be found here) Advantages: A lot of documentation (Pictures, Videos Parts list) Without belts Skechups of parts for printer also available Disadvantages: Print beds moves in y and z directions Uses a lot of 3d printed pieces Costs about $700. (Without printed parts, wiring, and controller)
How Does BioPrinting Work?
By Omair Tariq, Systems and Test Engineer How bioprinting works: In order for cells to survive and grow, they need a certain environment. This environment is provided in gel scaffolds, referred to as biopaper in laymen’s term. There are several ways of 3D bioprinting. One of these ways is to print a layer of gel […]
