OEM gone. Forty-week lead time. Make the part anyway.

Obsolete spares. Lost CAD. Last Call Orders. A photo of a cracked bracket on the shop floor. We turn whatever you have into a manufacturable model in minutes, route it to make-or-buy in days, and archive it in your Digital Warehouse the same on-demand model Europe's largest rail operators are betting €100M+ in savings on by 2030. So the next failure is a 30-second reorder, not another crisis.

What do you have to work with?

Most obsolete-part workflows start with a photo or an old drawing. Three free conversions either way — pick the input you actually have.

Photo

Photo of an obsolete part - even when the OEM is gone, the drawing is lost, and the supply chain is dead. We turn it into a manufacturable model.

—The 3D SPark Engine

Where the magic happens —
only it isn't magic.

Eighteen manufacturing technologies, simulated deterministically. Process-based costing. Geometric manufacturability. Lead time from actual cycle math. CO₂ from real material flows. Engineering knowledge poured into software - and it gives the same answer every single time.

Technologies covered

Built by Ex-Fraunhofer Additive-manufacturing Researchers

— Process-based

Costing that actually matches reality

No regression on quote history. Every step is simulated at process resolution — material, setup, run time, finishing, overhead. Assess one piece or 1000 with the same engine.

±5% Costing accuracy validated by Deutsche Bahn

— Geometric

Manufacturability, a verdict your engineers can defend

Manufacturablity is assessed by running your 3D geometry against the real capability envelope of each process - wall thickness, overhangs, wundercuts, tolerance class, surface finish. Simulation-based output. If it flags a problem, there is one.

— Cycle-math

Lead time you can defend

Built from machine cycle times, post-processing, queue depth, and logistics. Updated as supplier capacity shifts. Predicted ranges hold up against measured deliveries.

— Cradle-to-gate

CO₂ procurement can sign off on

Material origin to delivered part. Aligned with ISO 14067 and CSRD reporting needs. Real numbers — not badges, not vibes — comparing processes and routes side-by-side.

Approved by Deutsche Bahn

Four KPIs. One decision.

Every part returns the same standardized scorecard — feasibility, cost, lead time, CO₂, and a make-or-buy call. Even when the only input you had was a phone photo.

— Benefit for spare parts & lifecycle teams

Stop paying twice.

Long-tail spare parts charge you twice — bound capital tied up in inventory that may never move, plus downtime when the right part isn't there. Unit price is the wrong number to optimize — TCO is. A part 3–5× more per piece is the right buy when it avoids 10× in downtime and obsolete stock. We compress 40,000-part backlogs and 18-month manual analyses into portfolio sweeps, then archive each digital twin so the second failure is a 30-second reorder.

REACTIVE · TODAY

The part fails. Then you scramble.

OEM discontinued. Last Call Order missed. No CAD. 40-week lead times. Punitive MOQs forcing overstock on parts you may never use. Every reactive sourcing cycle costs more than the last, in time, downtime, and premium freight.
