Technology & Products
Key Products
AI-optimized propeller design; additively manufactured bronze alloy propellers and blades; stern gear systems; propeller repair and modification services
Technological Advantage
Robotic nozzle directed-energy-deposition process builds propellers layer-by-layer from bronze alloy, cutting production time from up to a month to two weeks, raising productivity up to 30%, and cutting a 200kg propeller's carbon footprint by 36% (1,743kg CO2)
Differentiation
Value Proposition
Replaces traditional sand-casting of large bronze marine propellers with robotic directed-energy-deposition additive manufacturing, cutting production time, raising productivity, and reducing carbon footprint while meeting marine classification standards.
How They Differentiate
Focus on large single-piece bronze marine propellers using DED metal AM with dual classification-society certification (Lloyd's Register + ABS), paired with AI-driven propeller design, versus competitors focused on WAAM prototypes or tooling applications
Market & Competition
Target Customers
Shipowners, shipbuilders, and operators of fast boats, tugboats, offshore vessels and electric vessels requiring propellers and stern gear
Industry Verticals
Marine, Offshore Oil & Gas, Shipbuilding
Competitors
RAMLAB (Netherlands, WAAMpeller - world's first class-approved 3D printed ship propeller); Wärtsilä (additive manufacturing for marine components); traditional sand-cast propeller manufacturers (e.g., Stone Marine Group)
Growth & Milestones
Growth Metrics
Parent Mencast Holdings Ltd (SGX Catalist: 5NF) reported FY revenue of SGD 53.49 million; EDIS investment helped grow related portfolio company sales from ~$3M to ~$8M
Major Milestones
1981: Founded; 2023: Began partnership with Enterprise Singapore, A*STAR and NAMIC on additive manufacturing propellers; May 2023: Signed MOU with ABS at Singapore Maritime Week to accelerate AM qualification for critical marine components; achieved world's first fully additively manufactured marine propeller certified by Lloyd's Register and ABS; 2026: EDIS ($3M) becomes top-20 shareholder of parent Mencast Holdings, supporting AI/AM growth strategy
