Technology & Products
Key Products
3D-printed ceramic/metal microlattice catalyst carriers; diesel oxidation catalyst (DOC) and diesel particulate filter (DPF) after-treatment devices for emergency generators; 3D Creative division offering DLP 3D printing total solutions (Carima DLP printer sales, 3D modeling, prototyping, and materials such as photopolymer resin, PBF metal powder, and WAAM metal wire).
Technological Advantage
Combines large-area DLP vat photopolymerization with metal hollowing: a polymer microlattice is printed, coated with metal, and the internal polymer core is removed to leave a hollow metal structure with improved heat resistance and durability. Proprietary nano-coating grows nanowires directly on the catalyst surface. Enables higher surface area (2-10x) and lower back pressure than conventional catalysts.
Differentiation
Value Proposition
Provides high-efficiency, low-back-pressure catalyst carriers and diesel particulate/exhaust after-treatment devices (DOC/DPF) built on 3D-printed microlattice structures that increase surface area 2-10x versus conventional catalysts, improving soot-reduction efficiency and durability while enabling custom designs for varied generator and industrial equipment environments.
How They Differentiate
Uses additive manufacturing to create free-form microlattice catalyst structures with higher surface area and lower back pressure than conventional extruded ceramic honeycomb substrates, addressing the bulk, cost, clogging, and noise issues of existing after-treatment devices, with customizable geometry per generator/equipment.
Market & Competition
Target Customers
Operators of diesel emergency generators and industrial facilities requiring exhaust after-treatment; environmental/energy sector OEMs and public and industrial institutions for pilot validation.
Industry Verticals
Environmental technology; energy (emergency power generation); industrial exhaust gas treatment; air purification; water treatment
Competitors
Corning (ceramic substrates and particulate filters); Ceracomb (세라컴, Korean ceramic honeycomb catalyst/DOC/DPF maker); Eco&Dream (에코앤드림, Korean DPF catalyst supplier)
