Why this company matters

Sigma Labs offers platform-independent in-process quality assurance (IPQA) software for metal and polymer additive manufacturing, shifting from a hardware-software hybrid to a software-only subscription model. This approach enables serial production qualification across different printer brands, reducing waste and improving yield through real-time monitoring.

The core product, PrintRite3D, uses acoustic and thermal monitoring to detect and classify defects during printing, supporting processes such as laser powder bed fusion (LPBF) and directed energy deposition (DED). Modules include INSPECT for real-time anomaly detection, CONTOUR for melt pool geometry analysis, and ANALYTICS for process optimization.

Target customers include aerospace and defense primes, advanced manufacturing firms, and metal AM OEMs. Named customers include Honeywell, Aconity3D, Materialise, DMG MORI, Additive Industries, and Northwestern University. The company aims for 10% penetration of the metal AM market by 2025, targeting $65 million in annual revenue.

Sigma Labs holds patented quality metrics designed for cross-manufacturer use, a key differentiator against competitors like Additive Assurance, Stratonics, and EOS. The company is publicly traded on NASDAQ (SASI) and reported $1.7 million in revenue for FY2021 with 104.5% year-over-year growth.
