"Solutions for physical problems"
I am an avid 3D printer and electronics enthusiast. Before the days of commercial hobby printers, I built my first 3D printers from scratch. I taught myself CAD so I can design my own parts. I also taught myself Eagle CAD to design my own electronic circuit boards. Here are some example of where 3D printing and electronic design have proved useful in the workplace.
Superfusion chamber for intracellular recording
The chamber allows continuous perfusion of live tissue with oxygenated Hartmann’s solution to maintain tissue viability. Shown right, single cells in a tissue sample targeted with a micropipette under fluorescent illumination for intracellular dye injection. This design was customised to suite the specific needs of our laboratory. It was printed in non-toxic ABS plastic.
Wall-mounted filament spool holder
Simple functional wall-mounted spool holder for 3D printer plastic filament. The design utilises nuts, bolts and nails easily sourced from any hardware store. Mounting the spool on the wall also makes great use of vertical space and keeps the desk uncluttered. This holder can easily support a 1kg spool on plaster board (dry-wall).
