EXCILLUM AB

Their core work

Excillum develops and manufactures high-performance liquid-metal jet X-ray sources used in industrial inspection, metrology, and non-destructive testing. Based in Kista (Stockholm's technology hub), they provide critical X-ray hardware that enables precise measurement and quality control in advanced manufacturing. Their technology feeds into broader inspection platforms — from MEMS component testing to digitized Industry 4.0 production lines. As a specialized hardware SME, they supply the core illumination technology that makes advanced X-ray-based inspection possible.

What they specialise in

How they've shifted over time

Excillum's H2020 trajectory shows a clear expansion from core hardware to integrated digital manufacturing systems. Their earliest involvement (2017) centered on validating their liquid-metal jet X-ray source for NDT through an SME Phase 1 instrument. By 2019, with MADEin4, they had moved into larger-scale Industry 4.0 metrology platforms involving AI, cyber-physical systems, and edge computing — a significant step from standalone hardware toward digitally integrated inspection infrastructure.

Excillum is moving from being a pure X-ray hardware supplier toward becoming a metrology technology partner embedded in smart manufacturing and Industry 4.0 inspection ecosystems.

How they like to work

Excillum operates primarily as a specialist technology contributor, having coordinated only one small SME Phase 1 project while participating in two larger Innovation Actions. Their 59 unique consortium partners across 13 countries indicate they integrate well into large, multi-national consortia where they supply a specific hardware capability. This makes them a reliable, focused partner — they bring a well-defined technology component rather than trying to lead broad research agendas.

Excillum has collaborated with 59 partners across 13 countries, primarily through two large Innovation Action consortia (CITCOM and MADEin4). Their network spans a broad European geography, reflecting the large consortium sizes typical of manufacturing and digital industry projects.

What sets them apart

Excillum occupies a rare niche as a commercial manufacturer of liquid-metal jet X-ray sources — a specialized technology with very few global suppliers. This gives them a distinct hardware edge in any consortium needing advanced X-ray illumination for inspection or metrology. For consortium builders, they offer a proven, industrially ready component that is difficult to source elsewhere, making them a high-value specialist partner for manufacturing quality control and semiconductor metrology projects.

Highlights from their portfolio

• MetalJet
  Only project they coordinated — an SME Phase 1 that validated the commercial potential of their core liquid-metal jet X-ray technology for non-destructive testing.
• MADEin4
  Largest funding (€1M+), positioned Excillum within a major Industry 4.0 metrology platform integrating AI, cyber-physical systems, and edge computing for electronics manufacturing.
