Robotics, Pipettes Medias and more for Micro Dispensing and Bio Printing
Automatic liquid handling or microdispensing of small liquid amounts is useful in the production of biochips, Lab-on-a-Chip (LOC), biosensors and for tissue engineering. Crucial elements are: - Precise manipulation / XY(Z) robotics - Micro-dispensing and other formes liquid manipulation - Printing medias
Robotic Stage
Small and precise mechanical manipulator made from recycled material and using open hard and software.
Can be used for:
- Laser cutting masks or light materials using a DVD-laser-diode
- Manipulate organisms or material
- Stage for microscopy
- Tissue engineering
(yeah yeah we print some fungi :-)
- Mini extruder
- SMD pick and place / stencil cutter
Basic principle:
- Two CD / DVD drives with stepper motor mounted cross wise
- Both drives are mounted fix, one is the object carrier the other is the manipulator
- Two stepper motor drivers (ex. pololu 4988) with micro stepping
- RepRap driver-software teacup on an arduino board
- G-Code may be generated with InkScape and G-Code plugin
- Controlled by ReplicatorG using G-Code
Calibration Measurement. With a micro stepping motor driver a precision of less than 60 um can be achieved.
