Short answer: 3Descu prints replacement plastic components on demand, from one piece to a small production run, with no tooling and no minimum piece count. Upload the model to the instant quote tool and the price and the delivery date for your order appear together. Production runs 7 days a week, and a small order can be printed in as little as one day.

We are one of the largest 3D printing factories in Eastern Europe, with 200+ industrial printers on one factory floor in Romania, ISO 9001:2015 certified, 1,500+ orders delivered for 450+ clients and rated 4.7 / 5. Our process is mostly FDM, with SLA resin for smaller, finer parts. Parts ship across the EU with DPD, GLS, Cargus, FedEx, DHL and others on request.

Why additive manufacturing for spare parts

Injection moulding needs hard tooling, and tooling only pays back at volume. When one bracket breaks on a packaging line, ordering thousands of units to justify a mould leaves you with stock you will never use, or waiting while a supplier aggregates demand.

3D printing removes the tooling step. The same model that produces one part today produces ten next month, with no setup penalty, so you pay only for the parts you actually need.

For a maintenance team that changes three things:

Obsolete equipment stays running. Manufacturers discontinue product lines, but machines run for decades. If no model exists, CAD modelling from your drawings, photographs and measured dimensions is one of the services we offer.
Response is fast. Production runs 7 days a week and high capacity applies to parts up to 300 x 300 x 300 mm, so a small, urgent part does not sit in a queue waiting for a tooling slot.
Stock becomes a file, not a shelf. Keep the model and print as components wear or break.

What we print as replacement parts

Manufacturing and automation

Production machinery is full of custom plastic details: chain guides, sensor housings, cable clips, guard mounts, covers and spacers. When one fails, the cost is the lost throughput, not the part. Typical work includes conveyor guides and wear strips, mounting brackets, machine guarding clips and fixings, cable management parts and sensor or switch enclosures.

Automotive and transport

Fleet and workshop teams manage obsolescence across vehicle lifecycles that outlast manufacturer support. We print interior trim clips and fasteners, bezels and non-structural interior components, workshop tool holders and fixtures, and prototype parts for modification projects. Large automotive parts have been produced in the past by splitting the model and bonding the segments.

HVAC and building systems

Climate control, access control and building automation hardware uses proprietary plastic parts that fail from UV exposure, thermal cycling or wear, and are often sold only inside an expensive assembly. We print ventilation grille components, non sealed duct adapters and connectors, thermostat housings and mounting plates, reader and bezel housings, and architectural trim.

Laboratory and non regulated equipment parts

Sample racks and tube holders, instrument trays and organisers, enclosure parts, workflow fixtures and transport containers. We do not produce regulated medical devices. If a component contacts patients or bodily fluids, or needs biocompatibility certification, it is outside our scope, so confirm the regulatory status of the part before you order.

Materials for functional spares

For an industrial spare, mechanical behaviour and dimensional stability matter more than looks. Across FDM we print 27 polymers, plus custom materials on request. The ones that cover most replacement work:

PETG, including PETG-CF and PETG-GF. Our general recommendation for most spares: good overall strength, chemical resistance, suitable for outdoor use, and the best material for the price. Ask for PETG first unless there is a reason not to.
ASA when the part has to hold up above roughly 80 °C.
ABS for impact strength at a low cost.
Nylon for wear surfaces and low friction parts.
PC and PC-ABS at the high end for impact strength and heat.
TPU and other flexible grades for gaskets, bumpers and strain reliefs.

SLA resin is the secondary route, used for small parts where fine detail and a smooth surface matter more than toughness.

We cannot print PEEK, ULTEM or PEI: the machines do not reach the temperatures those polymers need. We recommend a material for your application environment, and you set the final acceptance criteria.

Part size, and what happens above it

Rigid FDM parts go up to 500 x 500 x 500 mm by geometry. Flexible materials such as TPU and TPE go up to 250 x 250 x 250 mm. SLA resin parts go up to 218 x 122 x 220 mm. Material limits are tighter than the geometric maximum and are discussed with you when we quote.

Bigger components are not refused. We split the model into segments and join them with a bonding technique we use for exactly this purpose, including for automotive work in the past. There will be a visible connection line and possibly glue marks, so we always confirm with you first that this is acceptable.

From a broken part to a finished replacement

If you have a model. Upload it to the instant quote tool. The price is calculated in the browser and the delivery date is shown with the quote. The tool lists the accepted file formats and the size limit.

If you have drawings. Send the drawing. We check that the geometry is printable and flag features that need adjusting, such as walls below the printable minimum or internal cavities where supports cannot be removed cleanly.

If you have neither. Send photographs and the dimensions you can measure. CAD modelling is one of our three services, so we can build the model first and print from it.

Features drawn for moulding do not always transfer to additive. Draft angles stop being necessary, wall thickness has a printable minimum, and layer orientation changes how a part behaves under load. Those points are raised before production, as part of quoting.

Quality, documentation and what you receive

Every part is reviewed before it ships. Parts arrive with supports removed and post processed as standard, and that work is included in the part price.

Dimensional QC report: on request. Free on orders over €500, and available with a fee on smaller orders. Suitable for maintenance records.
Production photographs: free, on request, at any stage of production, so you can approve a part remotely before dispatch.
Quality system: ISO 9001:2015, our own certificate, our own machines, one legal entity.
If a part does not conform: a part that does not match the agreed specification is reprinted free of charge or refunded, under Article 5.5 of our manufacturing contract. In writing. Send photographs to start a claim.

We do not offer sanding, painting, priming or lacquering. Parts are supplied as printed and post processed, and any coating is done on your side.

Confidentiality for proprietary components

Replacement parts often carry proprietary geometry. A mutual NDA is available on request, drafted by us or by you, and signed fast once the text is agreed. Your price is calculated in the browser with nothing uploaded. Uploaded files are encrypted in transit and at rest in EU storage and deleted automatically 90 days after upload. Files are never shared with third parties or used for another customer.

Prices, speed and shipping

Price depends on part volume, geometry, wall thickness, material, quantity and real print time, so any figure given before we have the definitive model is an approximation from simulation and the final price can differ.

Three speed options appear side by side on the quote: Standard, Express at 20% more, and Economy at about 15% less depending on the order. Production runs 7 days a week, so production days are consecutive days. A small order can be printed in as little as one day. Larger parts and big batches take longer, and we do not publish a fixed day range as a promise: the date for your specific order is shown with the quote and confirmed after review.

Payment is by bank transfer as the main method, or Stripe card or PayPal, your choice. Orders over €500 can be paid 50% on confirmation and 50% before dispatch by bank transfer; smaller orders are paid in full up front. EU businesses with a valid VAT number outside Romania are invoiced under reverse charge after a VIES check.

Tracking is in the portal and by email at dispatch. We reply the same business day.

Scope boundaries

No safety certified or pressure bearing parts. If failure of the component creates a hazard, or the part works under pressure, it is outside our scope.
No shipping to the United States. We serve the EU and Europe.
FDM and SLA only. We do not run SLS, MJF, powder or metal processes in house. CNC machining is handled on request through our partner network: send the drawing and we come back to you.
No high temperature polymers. No PEEK, ULTEM or PEI.

FAQ

Can you print a part if I only have the broken original? Yes, provided we can get the geometry. Send photographs, the dimensions you can measure, or a drawing, and CAD modelling is quoted as part of the job before printing starts.

Which material should I choose for a replacement part? PETG for most cases: strong enough, chemically resistant, fine outdoors and the best value. Move to ASA only if the part has to survive above roughly 80 °C, to PC or PC-ABS for high impact and heat, or to nylon for wear and low friction.

Is there a minimum quantity? No minimum piece count. One replacement part is a normal order, and the same file prints ten next month.

How large can a single part be? Up to 500 x 500 x 500 mm in rigid FDM, 250 x 250 x 250 mm in flexible materials, 218 x 122 x 220 mm in SLA resin. Larger parts are split and bonded, with a visible seam we confirm with you first.

Will you sign an NDA before I send files? Yes. A mutual NDA is available on request and signed fast once the text is agreed.

Do you paint or sand parts to match the original? No. Parts ship with supports removed and post processed as standard; finishing beyond that is outside our scope.

Do you ship to the United States? No. We ship across the EU and Europe with DPD, GLS, Cargus, FedEx, DHL and others on request.
