Introduction: DIY Syringe Pump Using Stepper Motor
In this project, we use common materials such as acrylic sheets, screws and nuts to build a DIY Open Source Syringe Pump. The syringe pump is connected and controlled via an Arduino UNO Microcontroller Board.
The Syringe Pump can be used to infuse or withdraw solutions and dispense specified volume. It can also be connected to other sensors, such as pH meter, for automated balance of buffer solutions.
Tools Needed
- Screwdriver
- Allen Key
- Acrylic Laser Cutter
Materials Needed
- Arduino UNO: 1
- Motor Driver: 1
- 42BYG Stepper Motor (or any compatible stepper): 1
- 42BYG Stepper Motor Bracket: 1
- M4 x 70 mm Screw: 5
- M4 Nuts: 15
- M4-M4 Coupler:1
- "Joiner": 2

Step 1: Cutting Acrylic
The acrylic was cut from 2mm sheet. You can edit the design to suit your stepper motor and materials using the attached .SVG file.

Step 2: Joining the Pieces
The cut acrylic are fixed together using the M4-sized screws and nuts. You may follow the images for step-by-step instructions.
Step 3: Mounting the Syringe
The syringe pump is compatible with other syringes size of 1 ml, 10 ml, 12 ml, 50 ml.
Step 4: Fixing the Electronics
