Wanke Dianfeng scales SLA-printed lattice footwear to 50-micron precision, wins 2025 Red Dot design award

Wanke Dianfeng, a footwear brand under Guangzhou Sandi Intelligent Technology, says it has moved 3D-printed lattice-structure shoes from sample runs to simultaneous online and offline mass supply using an in-house SLA vat-photopolymerization process at 50-micron print precision. The single-shot SLA build eliminates 36 conventional shoemaking steps, cutting, stitching, and bonding, addressing delamination and adhesive-failure defects typical of assembled shoes. The brand's lattice geometry is tuned from a large domestic foot-shape dataset for wide, flat, and high-arch profiles, and is molded in a fully recyclable TPU with no outsourced tooling. The lineup, four core series plus Birkenstock-style casual and 3D-printed home slippers, passed ICAS anti-slip, 100,000-cycle flex-fatigue, and SGS environmental testing, and swept the 2025 German Red Dot Design Concept Award.

Most 3D-printed footwear on the market today stays at prototype or limited-drop stage; Wanke Dianfeng's claim to run parallel online and offline retail supply, rather than a single sales channel, is the more consequential part of the announcement if it holds at scale. Polymer vat photopolymerization carries none of aerospace's certification burden, so consumer footwear can move from geometry to shelf far faster than metal AM parts, and a Red Dot win gives the brand third-party design credibility beyond its own marketing. The company frames its own product demonstrations and social content, rather than paid channel partners, as the main customer-acquisition and market-education mechanism, which lowers distribution cost but leaves the durability and comfort claims largely self-tested pending independent user data.
