Case Study: Invoy achieves faster, cost-effective product launch with Protolabs' rapid injection molding

Invoy Technologies uses rapid injection molding for reusable and disposable parts in its next-gen medical device

Invoy, a medtech startup developing a handheld breath analyzer and coaching app to track fat burning, needed to accelerate time to market and cut production costs for a device that combines reusable electronics and single‑use disposables. The company faced difficult material and tolerance requirements, high iteration needs, and low‑to‑mid volume demand that made traditional steel tooling slow and expensive.

Protolabs provided two rapid injection‑molding options—prototype molds and on‑demand manufacturing (including overmolding)—to produce nearly 20 molded components for Invoy. Parts arrive in about 15 days versus the 8–18 weeks typical of standard molders; prototype molds averaged ~$5,000 with guaranteed life ≥2,000 shots and prototype parts about $2.15 (1,000 pcs), while on‑demand molds averaged ~$6,800 with parts at ~$1.18 each, yielding roughly $1 savings per piece past 2,000 units and avoiding steel tooling costs of at least 3x. Using Protolabs sped development, reduced costs, kept production under one roof, and materially enabled Invoy to bring its next‑gen device to market faster.
