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!

Why InFlux?

The middle ground should not be empty.

You can print a model in hours or dump tens of thousands of euros into industrial manufacturing. Why not something in between? Faster than 3D printing. Semi-industrial quantities.
Influx is the answer.

Evidence route

From an ambitious idea to a working machine.

Public resources

Built to be inspected, questioned, and improved.

From an idea
to a working machine.

We didn't build it all in one day. We took it step by step, making sure to improve along the way.

01
An idea appears

Sketches

My 3D printer is too slow and we can't afford industrial machinery. But what is in between?
Thus, we started sketching a machine that can manufacture high quantities for cheap.

  • Research the injection process
  • Separate the machine into sub-systems
  • Separate the sub-systems into individual components

Physical experiments

The beginning of InFlux

The idea proved possible, so we defined a brand identity. We don't sell a generic injection molding machine.
We sell Influx.

  • Design a brand name and logo.
  • Define our goals.
  • Study the market

Machine Prototyping

Plan for MK1

Branding and general architecture in place, it was time for engineering.
CAD, programming, simulations, test, repeat. There is no going back now.

  • Selecting and ordering components.
  • Mechanical and electrical design.
  • Making the first sub-systems work together.

First working prototype

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

Future product direction

Next up

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 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 of the prototype

Not perfect.
But it proves the concept.

A bad-looking first part doesn't prove the machine is poorly made. It proves the machine can control heat, melt plastic, control injection amount, flow cooling water, clamp molds and eject parts.

InFlux thermal testing in the laboratory

Thermal tests

Measurements defined the variables.

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

Landscape view of the InFlux dedicated motherboard design

Centralised control

Every action answers to the same hub.

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.

Repeatability

56 parts.
One mold.

A single 3D printed resin mold was able to produce 56 individual parts before failure. Analysis revealed failure points and proposed quality-of-life improvements. The next version WILL be better.

Prototype status

What is not proven.
. . .yet

Mold life

Resin mold durability across continuous, repeated cycles.

Continuous running

Stable output quality across longer, controlled runs.

Price reduction

Reducing the profitable selling cost as much as possible.

Max water temperature

Maximum temperature the mold cooling water reaches during normal operation.

Prototype notice: The public Influx Operator APK is still in development. Do not use it as a general-purpose machine controller. Constant machine supervision is required.

Integrity: SHA-256 checksums are published in checksums.txt. If the checksums don't check out, your file is NOT from Influx! Be careful of modified installations!
