Ideas, brought
to life.

I study electrical and computer engineering at Northeastern and build hardware, software, and the connections between them.

01 / Hardware & fabrication

A printer.
A personal pursuit.

ReVersaPrint is my custom 3D printer project, developed since 2023. The HT–HF–350 build brings together mechanical design, high-temperature materials, cooling, and the small details that make a machine work.

Inside the printer project

Designed in CAD.

Work through the assembly, part by part. The frame and toolhead renders show how the design comes together.

Built by hand.

From the frame and gantry to the toolhead and wiring, bring the design into the real world.

Documented as I go.

Share the build, tuning process, and upgrades so the learning can keep going.

02 / The toolhead

Every part.
With a purpose.

A closer look at my toolhead design, from the cooling duct and extruder to the mounting geometry. See the titanium parts and physical build below.
