# Further workshop and manufacturing research — 1 October 2026

Ten additions to the supplier directory, researched in French, Polish, Czech, Slovak and Romanian. This is a targeted continuation, not an exhaustive country survey. Public capabilities below are supplier claims unless a specific project is identified. None of these pages establishes current access to a 993 Turbo M64/60 donor, a complete editable engine model or a qualified printed engine.

## France

| Provider and primary source | Evidence and relevance | Qualification still needed |
|---|---|---|
| [MP REZEAU — Salbris](https://www.mp-rezeau.fr/rd-et-usinage/) | Integrated scan/metrology, mechanical design, polymer prototypes and 3/5-axis machining; the page connects this work to Cayman GT4 RS developments. Strong candidate to discuss an engineering project. | Exact 993/M64 experience, donor access and native CAD handover. Metal printing is not established. |
| [Rétro Ouest Conception — Chartres-de-Bretagne](https://retro-ouest-conception.fr/) | Unavailable classic-vehicle parts reproduced from an original, scanned and trialled in plastic. SLM metal printing and machining are advertised; the company also offers to look for a sample through its network. | Porsche availability, metal alloy, internal versus partner production, editable files and inspection. A network search is not a confirmed donor. |
| [SCAD Engineering — Pont-Audemer](https://www.scade.fr/retro-conception/) | Scan-to-parametric-CAD with drawings, STEP/IGES and native formats agreed in advance. Useful for the editable engineering model. | No Porsche case or in-house metal-printing service established; manufacturing must be arranged separately. |
| [eKmul — Brittany](https://ekmul.fr/prestation-de-scanner-3d-pour-piece-mecanique/) | Publishes editable SolidWorks reconstruction, STEP/IGES and scan/CAD deviation maps. Shows reconstruction of an industrial casing for EDF. | This is an industrial casing precedent, not a Porsche engine; donor access and downstream manufacture remain open. |

## Central and Eastern Europe

| Provider and primary source | Evidence and relevance | Qualification still needed |
|---|---|---|
| [INNOVAR 3D — Poland](https://www.innovar.pl/skanowanie-3d-porsche-911) | A documented 1980 Porsche 911 Turbo scan, alongside a separate [automotive scanning and reverse-engineering offer](https://www.innovar.pl/skanowanie-3d-samochodow-2). | The Porsche case produced a textured triangle mesh for animation. It does not prove parametric engine CAD, manufacturing tolerances or current donor access. |
| [B3D — Poland](https://b3d.com.pl/drukowanie-3d-metalu-pelen-zakres-uslug-od-modelu-po-precyzyjny-wydruk/) | Metal-printing service with design support and AL3D-Metal 200 SLM; complementary finishing/casting can involve partners. | Confirm alloy, actual machine for the job, usable build envelope and inspection. No Porsche reference established. |
| [do3ry motorsport — Czechia](https://www.do3ry.cz/sluzby/3d-skenovani) | Revopoint scanning, SolidWorks design, polymer prototypes fitted on the vehicle and subsequent CNC manufacture. | No specific Porsche case or direct metal-printing service established; define dimensional acceptance and supplier responsibilities. |
| [Paarts Additive — Czechia](https://www.paarts.cz/zakazkovy-3d-tisk/112-3d-tisk-kovu) | Xact Metal XM200G SLM service, 316L stainless steel, plus scanning and printed-part measurement. | Do not infer aluminium or titanium availability from generic metal capability. No Porsche donor established. |
| [Tridim — Slovakia](https://www.tridim.sk/) | Advertises metal/polymer printing, scanning, modelling and prototypes in Prešov. | Metal process, machine, alloys and project evidence are not specified on the reviewed page. Treat as a lead to qualify. |
| [3D DOT — Romania](https://3ddot.ro/pages/servicii-modelare-3d) | Scan/design/printing services; metal design explicitly accounts for shrinkage during sintering. | Exact production process, equipment, alloys, subcontracting and Porsche experience remain unconfirmed. |

## Suggested order of enquiry

Our assessment: discuss integrated mechanical work first with MP REZEAU and sample-to-part reproduction with Rétro Ouest Conception. For a native editable model and comparison against measurements, eKmul and SCAD describe relevant deliverables. Paarts and B3D are distinct metal-manufacturing leads. These are capability-based priorities, not endorsements or proven M64/60 suppliers.

Before commissioning, identify the exact physical part and who can supply it. Agree raw scan data, native editable CAD, STEP, datums, measured interfaces and a scan/CAD deviation report. Hidden internal passages need a separate capture method; an external optical scan does not recover them. Manufacturing acceptance is a separate step from geometry reconstruction.

No supplier was contacted, no quotation obtained and no private CAD transferred.

## Search and exclusion log

Representative local-language queries used in this pass:

- French: `France rétroconception scan Porsche carter impression 3D métal atelier`; `Porsche rétroconception pièces`; `Porsche scan 3D métal atelier`.
- Polish: `Polska Porsche części skanowanie 3D metal silnik produkcja`; `Porsche skanowanie 3D części`; `druk 3D metalu usługi B3D`.
- Czech: `Česko Porsche renovace výroba dílů 3D skenování`; `Porsche 3D skenování`; `3D tisk kovů služby skenování`.
- Slovak: `Slovensko 3D tlač kovov skenovanie`.
- Romanian: `România scanare 3D metal automotive`; `imprimare 3D metal servicii Romania`; `printare 3D metal servicii`.
- Hungarian follow-up: `fémnyomtatás szolgáltatás`; `fém 3D nyomtatás szolgáltatás`. Admasys was already listed; VARINEX was not added because its page could not be reliably re-read in this pass.

Existing firms were checked against the directory to avoid adding duplicate records. Dental-only metal printers, machinery sellers without a documented relevant service, and translated overseas landing pages were not treated as local automotive workshops. Supplier HTTP/robots checks are recorded separately in the directory; a successful fetch is not a capability audit.
