Technology & Products

Key Products

Medium-speed engine parts (pistons, cylinder heads, cylinder liners, engine blocks, front-end boxes); castings; binder-jetting sand 3D printers (BR-S1100 with 1100x520x450 mm build platform, mass-production BR-S2200 with 2200x1000x700 mm build volume, plus small research/education units); binder systems and sand materials; direct mold production and rapid prototyping services under the 'Sandgraphy' brand; proprietary SDI ductile iron and GT Metal wear-resistant alloy.

Technological Advantage

Sand 3D printing experience since 2014 inside its own production foundry; in-house large-format binder-jet printer developed in 2020; proprietary casting alloys; 28 patents. Its technology was named one of the National Academy of Engineering of Korea's 19 Industrial Technology Achievements of 2022.

Differentiation

Value Proposition

Integrates sand binder-jetting 3D printing into casting, printing molds and cores directly from CAD data without wooden patterns or tooling. It reports about 40% shorter process time and about 28% lower material cost on engine piston casting by consolidating multiple cores into one printed core.

How They Differentiate

Unlike pure printer vendors, it applies printed cores in its own serial engine-part production. It offers domestically built printers alongside binder, sand, printing services and finished castings.

Market & Competition

Target Customers

Marine, rail, power-generation and defense engine operators and OEMs; foundries seeking sand 3D printing equipment; research and education institutions; customers needing rapid prototype castings.

Industry Verticals

Marine/shipbuilding, rail, power generation, defense, automotive, large sculpture and cultural heritage

Competitors

ExOne/voxeljet (merged); 3DPTEK; other medium-speed engine parts makers such as HD Hyundai Marine Solution

Growth & Milestones

Growth Metrics

Revenue approx. KRW 23.0B (2025, per Saramin/Incruit); 59 employees per national pension data (Aug 2026); about 60% of revenue from exports.
