Roadmap | Concept-stage

A staged programme, gated by test results.

Each phase exists to remove a specific technical or regulatory risk before the next one starts. Timelines are deliberately not published while the programme is concept-stage.

Development roadmap

Six phases.

  1. Phase 01

    Formulation

    Develop and screen multiple hemp/mineral binder formulations.

    • Rheology
    • Extrusion
    • Setting
    • Density
    • Thermal performance
  2. Phase 02

    Print validation

    Produce repeated printed wall specimens under controlled conditions.

    • Nozzle consistency
    • Layer stability
    • Interlayer adhesion
    • Dimensional accuracy
  3. Phase 03

    Performance testing

    Characterize hardened material and assembly behaviour with recognised methods.

    • Compressive performance
    • Fire behavior
    • Thermal conductivity
    • Moisture behavior
    • Durability
    • Acoustic properties
  4. Phase 04

    Demonstration structure

    Print a small prototype building or full-scale wall system with partners.

  5. Phase 05

    Certification

    Develop a pathway toward applicable building and material standards.

  6. Phase 06

    Commercial pilot

    Partner with a printer manufacturer, developer and contractor to construct pilot homes.

Initial R&D target

First milestone: the 1 m × 1 m wall

Before trying to print an entire home, the first technical milestone is a repeatable full-scale wall specimen that demonstrates the fundamentals under realistic printing conditions.

  • 01Continuous extrusion
  • 02Stable multi-layer printing
  • 03Dimensional accuracy
  • 04Acceptable curing
  • 05Insulation performance
  • 06Moisture performance
  • 07Mechanical stability

Product roadmap

Four products on one material platform.

Product names are branding visualization for a concept-stage pipeline, not registered trademarks or available products.

02

PrintMix™

Pre-engineered dry material package combining graded hemp and binder for consistent site preparation.
Status: Future product
03

PrintWall™

Validated printed wall system with defined geometry, curing protocol and performance characteristics.
Status: Future system
04

PrintSystem™

Material, printing parameters, wall design and construction methodology offered through licensing or partnerships.
Status: Long-term platform

Process

The route we are building toward.

Feedstocks in, qualified wall systems out — with validation at every transition.
