Rapid Prototyping with 3D Printing

6 to 8 weeks typical for soft aluminium tooling on a single-cavity thermoplastic part

Tooling lead time

Soft aluminium injection tooling on a small polymer part typically needs 6 to 8 weeks from order to first shot. The programme runs are blocked the entire time, which forces engineers to freeze design intent before they have seen a physical article.[9]

EUR 15,000 to EUR 40,000 for an SPI 102 soft aluminium tool on a small housing

Tooling capex

An SPI 102 soft aluminium tool on a small housing runs EUR 15,000 to EUR 40,000 before the first part comes off the press. For startups this capex is often larger than the full prototype budget and blocks exploration of alternative geometries.[10]

Each engineering change order against cut steel tooling ranges from EUR 1,500 to EUR 8,000 and delays the cycle by 2 to 4 weeks

Engineering-change cost

Every change order against cut tooling costs EUR 1,500 to EUR 8,000 and delays the cycle by 2 to 4 weeks, which penalises learning. Teams either lock the design prematurely or pay a large tax on every iteration.[7]

External prototype suppliers quote 7 to 15 working days before first article plus shipping and customs

Supplier-timing friction

External CNC or casting suppliers typically quote 7 to 15 working days to first article, plus shipping and customs for cross-border EU orders. A single part can spend half its calendar life in logistics rather than evaluation.[30]

About USD 3,000 per printed intake manifold prototype in days versus about USD 500,000 and months for a tooled casting

Ford Motor Company

Automotive · US · 2017 · SLA and FDM

Ford used large-format additive manufacturing at its Research and Innovation Center in Dearborn to print intake manifold and spoiler prototypes. The company reported that a traditional cast prototype cost around USD 500,000 and took months, while a printed prototype cost a few thousand dollars and was ready in days, letting engineers iterate on performance parts much faster.[30]

Multi-material tennis racket iterations delivered in a day rather than weeks, around 85% iteration time reduction

Wilson Sporting Goods

Consumer goods · US · 2019 · PolyJet (Stratasys J750)

Wilson Sporting Goods uses Stratasys PolyJet printers to prototype tennis racket grips, dampeners, and cosmetic features in photorealistic multi-material. The design team reports that printing lets them review new models in a day instead of the weeks previously required to hand-fabricate and paint samples, compressing the research-and-development cycle for product launches.[31]

Six or more prototype cycles per product per year versus two with tooling, HP MJF and SLA workflows

Decathlon

Consumer goods · FR · 2020 · HP Multi Jet Fusion and Formlabs SLA

Decathlon, headquartered in France, uses HP Multi Jet Fusion and Formlabs SLA in-house to test sports gear prototypes in days. The published case study reports six or more prototype cycles per product per year rather than two when the team relied on external tooling and machining.[32]
