Frequently asked questions
Working with SANSIL 3D
Lead times, discounts, tolerances, confidentiality, shipping. If your question is not here, ask it directly — we answer within 24 working hours.
Business
What is the real lead time between my order and delivery?
The quotation goes out within 24 working hours. After that, allow 2 to 3 working days for a prototype, 5 to 8 days for a run of 50 to 250 pieces, and a negotiated schedule beyond that. The lead time stated on the quotation is firm: it accounts for the workshop's actual load at the time we write it.
How do the volume discounts work?
The unit price falls in bands: −6 % from 10 pieces, −12 % at 50, −18 % at 100, −22 % at 250, −30 % from 1,000. These apply to the unit price, and the quotation always shows the calculation. Preparation (€7.90) is charged once per order, not per piece.
Can I approve a sample before a production run starts?
It is mandatory above 50 pieces, and offered as standard below that. You receive one part, you fit it, you check the actual clearances. Production only starts once you have approved it in writing.
Do my files stay confidential?
Your files are used for your production and nothing else. They are not republished, not reused for another customer, not passed to a third party. An NDA is signed on request, before the files are even sent.
Do you offer white-label production?
Yes. Unbranded packaging, labelled with your own references, shipped straight to your end customer. Nothing carries our name, neither on the parcel nor on the paperwork.
What are the payment terms?
Payment with the first order. After that, 30 or 60 days end of month once the account is approved. For public bodies we work with your own payment authorisation process.
Which file formats do you accept?
STL, OBJ and 3MF for direct printing. STEP where design work is needed. A dimensioned 2D drawing, a photograph with a ruler in shot, or the original part will also do — we do the modelling.
What tolerances can you hold?
±0.3 mm as standard, ±0.15 mm on request and on identified dimensions. Beyond that the part needs machining, which we do not offer. Tight tolerances are agreed dimension by dimension, not across the whole part.
Do you have certified materials?
PC-FR is UL94 V-0 rated and the manufacturer's datasheet ships with the order. For every material, the manufacturer's datasheet (PDF) can be downloaded from the material page, and is attached to the order on request. We do not issue part certification: that is not our trade.
Do you ship across Europe?
Yes. Tracking is emailed when the parcel leaves, and there are no customs formalities inside the European Union. SANSIL 3D operates under the French small-business VAT exemption (article 293 B of the French tax code): no VAT is charged, in France or in the EU. The quoted price is the price you pay — nothing to add, and nothing to reclaim on your side.
Who owns the CAD files you create?
You do, as soon as the design work is paid for. You receive the STEP file and the native file, and you are free to have the part made elsewhere. It is written into our terms of sale.
What happens if a part is not to specification?
Tell us within 14 days, with photographs. If the fault is ours, the part is remade at no charge, carriage included. If it comes from a wrong dimension in the file supplied, we work out a solution together and the rework is quoted beforehand.
Are you insured?
Yes. SANSIL 3D is covered by a MAIF professional insurance policy: public liability and professional liability after delivery. A current certificate of insurance is provided on request, together with the quotation if you wish.
Individuals
How much does it cost?
It depends mostly on the weight of material and the machine time. An order starts at €22.90: a €15 minimum of parts, plus €7.90 for preparation and packaging. That is the price of a small object on its own, or of two or three small objects together. A medium object comes to €25 to €55, a large part €55 to €150, shipping extra. The online quote gives the exact price if you have a 3D file.
How long until I receive my part?
Allow 5 working days for production, plus shipping. The quotation goes out within 24 working hours, and nothing starts before you agree to it.
Which material should I pick if I know nothing about them?
Tell us what the object is for and where it will live. Indoors and unstressed: PLA. Daily use, something handled often: PETG. Outdoors, in the sun: ASA. Flexible: TPU. We choose it with you, and that is included.
How do I send you a file?
By email to support@sansil3d.fr, or by dropping it on the online quotation page. Above 9 MB, use a WeTransfer link: that is the limit for an attachment.
What if I have no 3D file?
That is the commonest case, and it is not a problem. A photograph of the object next to a ruler, with the main dimensions, is enough most of the time. For a simple part, the modelling is included in the price.
Can you repair a broken object?
We do not repair: we remake the broken part identically, or reinforce it where it gave way. Send the part, even in pieces — the geometry is rebuilt from the fracture faces.
Which colours are available?
Black, white, grey, blue, red, green, yellow, orange and natural, depending on the material. The colour is in the material, not painted on the surface: it cannot chip.
Is it strong?
A PETG part at 20% infill copes very well with daily domestic use. That said, a printed part breaks more easily along the layer lines, so we orient the print according to the load it will take.
Does it survive sunlight? A dishwasher?
Sunlight, only in ASA: PLA and PETG eventually dull and turn brittle. A dishwasher, no — none of our materials holds 70 °C through repeated cycles without deforming. Wash with a sponge.
Can I cancel my order?
As long as production has not started, yes, at no cost. Once it has, no: the part is made to your dimensions and cannot be resold. That is also why the 14-day right of withdrawal does not apply to bespoke work.
How does delivery work?
Tracked parcel, shipped from Morsang-sur-Orge. The tracking number goes out by email. You can also collect the part from the workshop, by appointment.
What if the part is not right for me?
Tell us within 14 days, with photographs. If the mistake is ours, we remake it at no charge. If the part matches what was approved but does not suit the use, we look for a solution — often a change of material or of orientation.
Can I send you a file larger than email allows?
Yes. Files up to 500 MB are uploaded straight from your browser on the quotation page — they never pass through an email attachment. A 400 MB STL is no problem. If your file is larger, zip it: STL compresses very well, often to a fifth of its size.
Still unsure? Describe your part and we will tell you what is realistic.
