Engineering

Built from scratch.
Down to the last wire.

A precision syringe pump designed and fabricated entirely by hand — combining 3D printing, Arduino, and custom electronics.

Custom Syringe Pump

Featured Project

Custom Syringe Pump

A syringe pump that precisely controls the flow rate of fluid from a syringe, delivering very small, accurate volumes over a set period of time — used in medical and laboratory research settings where consistent, controlled fluid delivery is critical.

How It Works

A NEMA 17 stepper motor drives a lead screw via a flexible aluminum coupler. The screw moves a carriage linearly, pushing the syringe plunger at a programmable rate — controlled by an Arduino Uno.

Design & Build Process

Housing designed in Fusion 360 and 3D printed in PLA/ABS. Electronics hand-wired with a custom harness. Firmware written in C++ using the Arduino IDE.

Outcome & Results

Accurate to within a few fractions of a milliliter per test. Flow rate can be adjusted in real time via a potentiometer knob — a fully functional lab instrument.

About

Samuel Miller.

Nashville-based mechanical engineer with a passion for work that lives at the intersection of aesthetics and function.

I grew up in Littleton, Colorado with an early interest in designing, building, and creating. Math was always the subject I excelled at and enjoyed most. After graduating from Littleton High School in 2024, I began studying Mechanical Engineering at Vanderbilt University with a minor in Digital Fabrication — expected graduation Spring 2028.
