The workshop

SANSIL 3D is an FDM 3D printing workshop based in Morsang-sur-Orge, 20 km south of Paris. We make parts that do a job: prototypes, workstation tooling, enclosures, spare parts you cannot buy any more.

Who actually makes your parts

SANSIL 3D is the sole trader business of Sébastien Boudignon, registered under SIRET 940 902 281 00010, activity code APE 28.99B, in Morsang-sur-Orge (91390), France.

You deal with one person from the first message to delivery. The same person reads your enquiry, chooses the material, starts the print and packs the parcel. There is no sales desk promising a lead time production cannot hold.

How an order runs

Send whatever you have: an STL or STEP file, a drawing, a photograph of the part next to a ruler, or a sketch. We reply within 24 working hours with a firm price, the recommended material and a lead time.

Before starting, we check the file for printability: walls too thin, impossible overhangs, material shrinkage across large flat areas. When a problem shows up, you hear about it before production, not when the parcel arrives.

Every part is checked before packing. For a production run, a sample is sent and approved by you before the rest is started.

The machines and their limits

We print in FDM, with in-house capacity matched to your volume, up to 350 × 350 × 350 mm in a single piece. Above that the part is split into assembled sub-units, with the joints placed where they show least.

Multi-material and multi-colour through the thickness are both possible: the colour runs through the material, it cannot chip off the way paint does.

We do not do resin. For micro-detail beyond what FDM can hold, we say so and point you to a partner rather than deliver a disappointing part.

No finishing, and we say so up front

Removal of print supports is included. Sanding, primer, paint, varnish: we do not offer them. An FDM part comes out with its layer lines visible; that is the nature of the process.

We would rather state it than let you expect the look of an injection-moulded part. If surface appearance matters to your project, tell us: print orientation and layer height change a great deal, and that we do know how to optimise.

The 20 materials available in the workshop

Material	Rate	What it is for
PLA	€€	Precision and detail. Deforms above 55 °C: not for a car in the sun.
PETG	€€	Everyday functional use. Strong, stable, unbothered by damp.
ABS	€€€	Holds to 90 °C. Drying at 80 °C required beforehand, heated chamber.
ASA	€€€	The ABS that does not yellow in the sun. Anything that lives outdoors.
TPU	€€€	Flexible like a rubber. Seals, dampers, impact protection.
PA6-CF	€€€€	Carbon-filled nylon. Stiff, light, low creep under load.
PC	€€€€	Polycarbonate: impact and temperature beyond 110 °C.

Also in the instant quote: PPS-CF, which holds up to 200 °C, PPA-CF for 180 °C continuous, and PC-FR rated UL94 V-0 for regulated applications, with a material datasheet supplied.
