On launches Cloudmonster 3 lineup and scales LightSpray 3D-printed uppers

On unveiled the third‑generation Cloudmonster family — Cloudmonster 3, Cloudmonster 3 Hyper, and the LightSpray Cloudmonster 3 Hyper — and for the first time is scaling its proprietary LightSpray 3D‑printed upper into a mass‑market product. The LightSpray Cloudmonster 3 Hyper is a men’s US 8.5 at 205 grams and is slated for a limited release at on.com and On retail stores across North America on March 5, followed by a full global launch on April 16, 2026.

The upper technology at the center of the drop is LightSpray, On’s spray‑based, robot‑assisted process that the reporting describes as "completely 3D‑printed." The upper is formed in under three minutes by a single robot arm, a workflow 3dprintingindustry details as eliminating layered construction to deliver a seamless, porous geometry designed for temperature regulation and a "form‑fitting fit without pressure points."

Construction on the LightSpray Cloudmonster 3 Hyper is intentionally minimal. Reporting consolidates the shoe to eight total parts — "one upper, two midsole pieces, and five small rubber elements" — with a two‑piece Helion HF midsole referenced across outlets. Sources use slightly different adjectives for the foam, calling it Helion HF "supercritical" in one brief and Helion HF "hyper" foam in 3dprintingindustry’s copy; On’s official spec sheet will be the final arbiter of the nomenclature.

On is pairing the printed upper with a proprietary sock engineered to complement the upper’s breathability and provide targeted cushioning, VoxelMatters and 3dprintingindustry report, positioning the Hyper as a lighter, speed‑oriented silhouette that preserves Cloudmonster’s high‑mileage training identity. MarathonHandbook frames the Hyper as keeping the Cloudmonster "built for the long haul" while stripping back weight and nonessential structure; the 205g figure represents a reported 90‑gram reduction versus the standard Cloudmonster 3.

Scaling LightSpray is not purely a product announcement — it’s a manufacturing pivot. On opened a second automated LightSpray production facility in Busan, South Korea, which 3Druck reports will be the first to produce the Cloudmonster 3 Hyper. 3Druck cites the company as talking about a "30‑fold" increase in capacity, while InsideHook reports a Korea site equipped with "30‑plus LightSpray robots." Those capacity claims hinge on throughput and quality control: 3Druck cautions that success depends on process stability, reject rates, and material costs remaining under control.

Price for the full global launch is reported at $280 by MarathonHandbook citing Footwear News. With a March 5 limited drop and an April 16 global rollout, On is making its clearest bet yet that robot‑sprayed, structurally printed uppers can move from demo runs to real production — provided the Busan plant can deliver the promised speed and yields.
