EHLS/ Ephemeral Hardware-Locked Streaming

The operating system
for secure distributed
manufacturing.

EHLS streams G-code instructions directly to the machine in real-time. Each line is executed and destroyed from memory immediately. No file ever persists. No IP ever escapes.

Distribute production, not IP

Designs never leave your control. Authorised machines print on demand, then forget.

License every print

Bind production to a contract. Per-part rights, quantities, geographies, expiry.

Trace every part

A tamper-evident certificate for every part — machine, material, parameters, operator.

Product Liability Directive

Directive (EU) 2024/2853 · Effective 9 December 2026

Right to Repair Directive

How it works

01 — Your cloud

Parts stay in your cloud

Every design, licence, and print is recorded in real time. Only encrypted commands are streamed out — never the file itself.

02 — The gateway

A secure bridge to the machine

The gateway feeds instructions to the printer one line at a time, wiped from memory after use. No file ever lands.

03 — The machine

The machine reports back

It streams its status back through the gateway to your cloud, then issues a tamper-evident certificate for the finished part.
