How to Get a Prototype Made in Türkiye: Step-by-Step Guide

Short answer

To get a prototype made in Türkiye, prepare a 3D model (STEP for machined or sheet metal parts, STL or 3MF for 3D printing), add a drawing if some dimensions are critical, choose the process by what the prototype must prove (appearance, fit or function) and request a quote from a manufacturer or an online manufacturing platform. On Uretyco, a Türkiye-based platform in Gebze/Kocaeli, you upload the file, see the price on screen for supported files and processes and order online, even a single piece. A manufacturing partner in Türkiye produces the part, and Uretyco inspects it before shipping it to you.

Step by step

1
Define the goal
Decide whether the prototype checks appearance, fit or function.
2
Prepare the files
A 3D model, plus a drawing for critical dimensions, threads and finishes.
3
Choose process and material
Match them to the goal, not to the final product by default.
4
Mark critical tolerances
Tighten only fits, bores and sealing faces.
5
Get a quote
Upload, select process, material, finish and quantity, and review price and delivery date.
6
Order and follow production
Confirm the scope, pay and follow the order status.
7
Check on delivery
Compare the parts with the order; open a request if something does not match.
8
Test and revise
Record the results, update the model under a new revision name and quote again.

Prepare the files

STEP/STP for CNC machining, sheet metal, molding and casting: it carries exact solid geometry.
STL or 3MF for 3D printing: check units, scale and that the mesh is closed.
DXF for flat laser-cut profiles: 1:1 scale, closed contours, no duplicate lines.
A PDF drawing when threads, fits, tolerances, roughness or finish cannot be read from the model.
File names, part notes and CAD metadata (such as the author in a STEP header) travel with the file, so remove names you do not want to share.

Choose the process by prototype goal

A look prototype checks shape, size and appearance. A fit prototype checks assembly with mating parts. A function prototype tests behavior under real load, heat or movement, so its material must be close to the final one. The last column shows the tolerance Uretyco applies when the drawing gives none.

Process	Best for	Strengths	Watch out for	Default tolerance
FDM 3D printing	Early concept models, simple fit checks, fixtures	Low cost, fast; PLA, PETG, ABS, ASA	Layer lines; weaker across layers	±0.5 mm or ±0.5 %
SLA / PolyJet	Look models, fine details, master patterns	Smooth surface, sharp detail	Many resins are brittle and UV-sensitive	±0.2 mm or ±0.2 %
SLS / MJF	Functional plastic parts, snap fits, small batches	Durable nylon (PA12, PA11), no supports	Grainy surface; cavities need powder escape holes	±0.3 mm or ±0.3 %, whichever is greater
CNC machining	Functional metal and engineering-plastic parts, precise fits	Real production materials; tight tolerances where specified	Tool access; every extra setup adds cost	ISO 2768-mK (metals), ISO 2768-cK (plastics)
Sheet metal and laser cutting	Brackets, panels, enclosures	Same process as series production	Bend radius, bend relief, flange length	±0.1 mm cut, ±0.5 mm formed, ±1° bend angle
Vacuum casting (silicone mold)	Small batches that look molded	Polyurethane parts from a master model	Needs a master model; limited mold life	Agree it on the drawing

Test the riskiest feature first

Prototype the feature most likely to fail (a snap fit, thread, hinge or seal) in the cheapest process that still answers the question. Consider metal 3D printing only when the geometry cannot be machined or cast.

Material and quantity

Choose the material by the property you test: stiffness, impact strength, heat or chemical resistance, or appearance. A printed ABS or nylon part shows shape and fit but does not behave exactly like an injection-molded one; a machined aluminum part behaves like the final aluminum part. A single piece is possible. A few pieces at once usually lower the unit price because setup is shared, but order only what you will test.

Tolerances

Without a tolerance on the drawing, the defaults in the table apply; injection-molded parts follow DIN ISO 20457 (formerly DIN 16742), tolerance group TG6, unless agreed otherwise. Tighter tolerances apply only when stated on the drawing and accepted in the quote. Use them only for bearing seats, press fits, sealing faces and mating holes.

What drives cost and lead time

Size and geometry: volume, deep pockets, thin walls, undercuts and supports.
Process and setups: several CNC setups or special tools cost more; 3D printing needs little setup.
Material: common grades are sourced faster than special alloys or certified stock.
Quantity: setup is shared, so the unit price usually falls as quantity rises.
Tolerances, finishes and documents: each adds operations and time.
File quality and urgency: unclear files cause clarification loops; a short deadline can raise the price.

From quote to delivery

On Uretyco, supported files and processes are priced on screen as soon as you choose process, material and quantity. Documents or non-standard requirements are assessed in a technical review, and any extra charge needs your approval before production. You pay by card through iyzico. The estimated delivery date shown when you order is binding; if Uretyco foresees a delay, it proposes a new date, and if you reject it, the affected parts are refunded in full. The manufacturing partner sends finished parts to Uretyco, not to you; Uretyco inspects them visually and with a sample check of critical dimensions, and ships only approved parts.

Iterate and move toward production

Give every changed model a new revision name and quote it again.
Change one major thing per revision, so you know what solved a problem.
Before a pilot batch, freeze material, finish, drawing and critical dimensions.
At series start, consider a First Article Inspection report (FAIR) or a material certificate; both are optional and requested at quote.
For plastic parts, silicone molding can bridge the gap until injection molding pays off.

How it works with Uretyco

Uretyco (URETYCO TEKNOLOJİ A.Ş.), Gebze/Kocaeli, is the seller and your only contract party.
Independent manufacturing partners in Türkiye produce the parts, and Uretyco serves customers in Türkiye.
Partners see the files and production details, never your name, company, contact details, address or the price you paid.
Every order passes Uretyco quality control before shipment.
Processes: CNC machining, 3D printing (FDM, SLA, SLS, MJF), sheet metal and laser cutting, silicone and injection molding, die casting and finishing.

Custom parts and returns

Prototypes are made to your files, so there is no right of withdrawal or change-of-mind return. Your rights for defective, missing, wrong or damaged parts are never limited: open a request on the part.

Frequently asked questions

Can I order a single prototype?

Yes. Uretyco accepts single pieces as well as small batches, repeat orders and series production. The unit price usually drops when several parts share one setup.

How much does a prototype cost in Türkiye?

There is no fixed price: it depends on size, geometry, process, material, quantity, tolerances, finish, documents and deadline. A small FDM concept model is usually much cheaper than a machined metal part with tight tolerances. Upload the file to see the price for supported files and processes before you order.

How long does a prototype take?

It depends on process, material availability, finish, inspection scope and partner capacity, so Uretyco publishes no typical duration. The estimated delivery date shown when you order is binding; if it cannot be met, you get a new date proposal and can reject it for a full refund of the affected parts.

I only have a sketch or a photo. Can I still order?

Uretyco manufactures from the files and specifications you provide, so you need a 3D model, or a DXF for flat parts. A photo or sketch does not define reliable dimensions, but it helps as an appearance reference next to the model.

Will the manufacturer see my design and my identity?

The partners that quote or produce see the files under the Uretyco NDA, through short-lived links; those not selected must delete them. No partner sees your name, company, contact details or address, and all communication runs through Uretyco.

What if the prototype does not match my order?

Open a request on the part with photos and measurements. If the part does not conform to the approved order, repair, a remake or a refund is at Uretyco's cost, and consumers choose among their statutory remedies. A part that matches your approved file is generally not defective just because testing shows the design should change.
