FOR HEAD OF SPARE PARTS · OBSOLESCENCE MANAGERS · AM HUB LEADS

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

I only have a photo

jpg · png · phone snap

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.

Drawing

The 1992 service manual still has dimensions. We reconstruct the 3D from the views — even from yellowed PDFs and faxed copies.

—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.

Portfolio Screening: get ahead of the next crisis.

10k+ PARTS SCREENED

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.

PROACTIVE · PORTFOLIO SCREENING

Screen now. Act before the failure hits.

Run your full spare-parts catalog through the engine. Parts at obsolescence risk and upcoming Last Call Orders are flagged. Alternative manufacturing and sourcing routes are ready. Digital twins are archived. The next crisis does not happen.

START HERE · CONSULTING SPRINT

Send us your parts list. We do the rest.

No IT involvement. No software setup. No training. Just share a catalog, even 1,000 parts is enough to start, and our engineers run the full screening, interpret the results, and hand you a prioritized action plan with savings estimates ready to present to leadership.

Stop paying twice.
Start with three parts.

Photo, drawing, CAD, or ERP record — bring any three obsolete parts. We'll turn them into manufacturable models, route them to make-or-buy, and archive the digital twins. The next failure won't be a crisis. The capital won't be frozen.
