Overview
This theme is about the materials and processes that make future hardware possible. AI data centres need power electronics and advanced packaging; robots need motors, sensors and precision components; aerospace needs lightweight materials; batteries need supply-chain innovation; defence needs domestic manufacturing capacity.
The public microcap universe contains many failed or distressed additive-manufacturing stories, so this section prioritises companies with real revenue, strategic materials exposure, customer qualification paths and links to defence, aerospace, semiconductors or electrification.

| Titanium supply | Aerospace and defence need strong, lightweight materials. | IperionX. |
| Specialty semiconductors | Space, solar and sensors rely on high-purity materials. | 5N Plus. |
| Battery cathode process | Localised low-cost battery production needs better processes. | Nano One. |
| Metal AM repeatability | Customers need qualified, repeatable parts not prototypes. | Velo3D, broader AM ecosystem. |
| Advanced packaging | AI chips need complex package and wafer-level processes. | ACM Research, Aehr. |
Company Profiles
1. IperionX · IPX.AX / IPX
Low-carbon titanium and critical minerals
IperionX is a strategic materials name focused on titanium production and mineral supply-chain resilience. It links directly into aerospace, defence, additive manufacturing and reshoring.
- Why it matters: titanium is critical for high-performance manufacturing.
- Risks: scale-up, customer qualification, funding and commodity/project execution.
2. 5N Plus · VNP.TO
Specialty semiconductors and engineered materials
5N Plus supplies specialty semiconductors and engineered materials used in demanding applications including space solar cells, imaging and advanced electronics.
- Why it matters: higher-quality revenue-backed route into advanced materials.
- Risks: cyclicality, customer concentration and materials pricing.
3. Nano One Materials · NANO.TO
Battery cathode process technology
Nano One develops cathode production process technology for battery materials. The thesis is supply-chain localisation and lower-cost production.
- Risks: commercial adoption, licensing timing, cash burn and battery-cycle volatility.
4. Velo3D · VELO
Metal additive manufacturing
Velo3D is highly relevant to aerospace and complex metal parts, but financial risk is severe. It is a technology watchlist name, not a core investment-quality name.
- Risks: liquidity, debt, customer concentration, manufacturing execution and dilution.
Future Scenarios
Bull case: reshoring, defence demand and AI hardware needs lift strategic materials, semiconductor manufacturing and automation suppliers.
Base case: advanced materials grow selectively, while speculative 3D-printing names continue to struggle.
Bear case: industrial capex weakens, customers delay qualification and cash-burning additive names dilute heavily.
Signals to Watch
- Customer qualifications in aerospace/defence.
- Battery material offtake or licensing deals.
- Semiconductor equipment orders.
- AM system utilisation and service revenue.
- Government supply-chain funding.
Metrics That Matter

Summary
Materials & Advanced Manufacturing is highly relevant, but quality control is essential. IperionX and 5N Plus are the more interesting strategic-materials names; Nano One is a battery-process optionality name; Velo3D and other additive-manufacturing stories need severe caution until balance sheets and repeatable demand improve.
Current working conclusion: prefer critical materials, semiconductor manufacturing and qualified industrial supply-chain bottlenecks over unproven 3D-printing narratives.
