Integrated prototype / active calibration

Real manufacturing.
Desktop scale.

InFlux Origin bridges the gap between a 3D printed prototype and industrial manufacturing with real thermoplastic shots, resin 3D printed molds, and an easy-to-use operator app!

00 / Why InFlux

The expensive middle ground should not be empty.

Teams can print a model in hours or commit to industrial tooling. InFlux is built for the critical space between them: process learning, functional evidence, and short-run validation before steel makes sense.

01 / Evidence route

From a difficult idea to a measured machine.

02 / Public project

Built to be inspected, questioned, and improved.

One platform.
Three levels of maturity.

Each version exists to remove a different kind of uncertainty.

Proving the concept

The First Prototype

The project began with CAD models, motion tests, sensor calibration, early firmware, and a complete plan for the first machine.

  • Selecting and ordering the components
  • Bringing the first systems together
  • Setting the machine architecture
Early InFlux wireframe studies
MK1
Current working prototype

Origin MK1

Our first complete machine capable of producing real injected parts. Although the automations aren't perfect, it gets the job done, and it certainly does it cheaper than industrial solutions.

  • Desktop sized
  • Water-cooled resin and metal mold compatibility
  • Fully compatible with the Influx Operator app

NEXT UP
Future product direction

Origin Mk 2

The next version will focus on a fully automated and monitored process, with water, molten plastic, and mold pressure monitoring. Designed for continuous thrustworthy operation.

  • Full machine enclosure
  • Pressure sensing and temperature balancing
  • Printed molds lifetime improvements

Interactive assembly

Inspect the machine, not just the pitch.

No need to take our word for it, convince yourself. Take a look at the InFlux Origin Mk. 1.

InFlux Ecosystem

Three systems. One machine.

01 Operator interface

Everything the operator needs, in one place.

InFlux Operator

A dedicated interface with internet internet connectivity. It includes complete machine monitoring, control and servicing functions.

02 Control electronics

This is where the machine starts thinking.

Origin Motherboard

A custom PCB that serves as the central hub for every part of the machine. Offers the possibility for easy expansion and component replacement.

03 Thermal testing

We measure instead of guessing.

Thermal Lab

We measured heating and cooling time, temperature stability, sensor precision and heat spread to improve the next version of the machine.

Team Volta Circuits

Three disciplines.
One physical result.

InFlux is built at the intersection of engineering, analysis and business. Nothing is left out.

Proof / Current evidence

The first part is not perfect.
That is why it matters.

It confirms that the system can heat, move, inject, and produce a physical result. Its defects also identify the work ahead: venting, fill behavior, process tuning, and tool life.

Evidence 02 / Thermal campaign

Measurements changed the design.

Thermal camera passes and logged sensor data exposed heat loss, hot spots, and control behavior before those weaknesses became hidden inside an enclosure.

Evidence 03 / Integrated control

Every action has a supervisor.

The connectivity board communicates with the user, so the motherboard can focus on safety and precise control. All settings, sensors and outputs are controlled by the motherboard, running an STM32.
