Baltimore Under Ground Science Space
About
BUGSS is a citizen science lab in Baltimore, MD, USA. They work with multiple forms of bioprinting with a focus on non-medical R&D toward new materials and forms. BUGSS has three different types of 3D printers – FDM, Syringe, and DLP. With these tools they are exploring direct printing of plant cells, printing scaffolding for bacterial growths, and other processes.
Research Projects
DLP Printing
This project focuses on the development of a bioprinting platform utilizing a custom-built DLP (digital light projection) 3D printer. The primary accomplishment of the work to date are:
• development and modification to the printer itself
• engineering and testing of bio-compatible photopolymers
• development of DLP tools in Xylinus, a 3D printer control platform in Rhino/Grasshopper
• designing, printing,and analyzing of 3D scaffolds
Nascent work has been done regarding:
• testing cytotoxicity and bacterial biofilm formation with the resultant 3D prints
• designing a bioreactor and planning post-print cell growth processes
The rough lab notes for this work are open and available at this stream.
Syringe Printing with Plant Cells
This project focuses on the development of a syringe-based 3D printer capable of direct printing of plant cells suspending a an agar-based media.The primary accomplishment of the work to date are:
• development of the printer with a pneumatically controlled syringe housed in a hot water jacket, with additional thermal and aseptic controls
• formulations of materials to provide proper phase transition and cell support
• development of syringe tools in Xylinus, a 3D printer control platform in Rhino/Grasshopper
• designing and printing simple structures capable of holding 3D shape
Nascent work has been done regarding:
• testing cell culturing protocols and proving survival of printing process
• designing processes for sterile growth and development of plant cells
Printing Polycaprolactone Scaffolds with a custom FDM printer
This project utilizes a custom FDM (fused deposition modeling) printer to create scaffolds utilizing the biocompitible plastic polycaprolactone (PCL). The primary accomplishment of the work to date are:
• modification to the printer to work with highly flexible filament
• creating PCL filament and experimenting with particulate additions to the plastic
• development of filament tools in Xylinus, a 3D printer control platform in Rhino/Grasshopper
• designing and printing scaffolds utilizing linear geometries
