Technology & Products
Key Products
Stainless Steel 316L filament (1.75mm, 91.7% metal content by weight, 61.5% by volume); Microwave sintering furnace/densification system; Pellet extrusion multi-material 3D printing system; Microwave Digital Casting system (combines AM with microwave heating for sacrificial mold creation)
Technological Advantage
Proprietary microwave sintering process (non-resonant topology) overcomes industry constraints; reduces part processing time from days to hours; enables affordable metal 3D printing without high-cost equipment investment; extends market to cost-conscious manufacturers and service bureaus; Microwave Digital Casting provides novel path for metal casting (bypass molten-metal pouring)
Differentiation
Value Proposition
Reduces metal sintering process time by 80–90% (from days to hours); enables cost-effective metal 3D printing through microwave densification (debinding and sintering); provides compatible metal filaments for existing FDM printers; eliminates need for high capital investment in traditional sintering furnaces
How They Differentiate
Microwave-based sintering vs. conventional furnace-based sintering; 80–90% faster processing (hours vs. days); emphasis on affordability and accessibility for cost-sensitive customers; compatible with existing FDM hardware (low adoption barrier)
Market & Competition
Target Customers
Metal 3D printing service providers, manufacturers seeking affordable metal AM capabilities, existing FDM printer users seeking metal printing capability without capital investment
Industry Verticals
Aerospace; Automotive; Medical devices; Jewelry; Industrial tooling; Casting
Competitors
