Short answer: 3Descu prints assembly jigs, drill guides, inspection aids and handling trays in FDM polymers on a floor with 200+ industrial 3D printers in Targu Jiu, Romania. You upload the file, the instant quote shows the price and the delivery date together, and production runs 7 days a week. Minimum order is €20 and there is no minimum piece count, so a single fixture is a normal order.

3Descu is one of the largest 3D printing factories in Eastern Europe, ISO 9001:2015 certified, rated 4.7 / 5, with 1,500+ orders shipped for 450+ clients.

Why production teams print manufacturing aids

A jig is a one-off. It exists to hold one part, in one cell, for one process, and it usually changes once somebody has used it for a week. That is the shape of work additive manufacturing handles well.

Iteration without retooling. Moving a locating pin or adding a probe slot means editing the model and printing again. There is no tooling to rework and no minimum batch to justify.

Geometry you would otherwise machine in several setups. Part nests, chip reliefs, internal channels, integrated clips and datum faces can be printed as one body instead of assembled from a plate, standoffs and fasteners.

File instead of shelf. Keep the model, not a rack of fixtures. Print replacements when a guide wears or when production moves to another cell.

Speed on small parts. Lead time depends on the order. A small order can be printed in as little as one day, and speed and high capacity apply to parts up to 300 x 300 x 300 mm. Larger parts and big batches take longer. The date for your specific order is shown with the quote, so nothing here is a blanket promise.

Materials for shop floor aids

3Descu prints FDM and SLA only. For jigs and fixtures, FDM is the process that matters, and the material choice is usually simpler than people expect.

PETG is the default recommendation. It is the best overall material for the price: tough, chemically resistant, dimensionally well behaved and suitable for outdoor as well as indoor use. Most assembly jigs, trays and guides do not need anything else. PETG-CF adds stiffness when a gauge arm or long fixture body needs to resist flex.

PA12 nylon suits aids that take repeated snap loading or vibration, and soft jaw inserts that must not mark a finished surface. Nylon absorbs moisture, so design clearances a little looser.

ABS and ABS-CF give a rigid, stable body that takes post-print tapping and reaming reasonably well. Useful where a fixture bolts to a T-slot table and must not flex.

PC and PC-ABS are the high end of the rigid range on this fleet.

ASA only when the part must work above roughly 80 °C. Below that, PETG covers the same ground at a lower price.

TPU and other flexible grades work for protective nests, pads and bumpers. They print slowly, so expect a longer production time than a rigid part of the same size.

3Descu does not print PEEK, ULTEM or PEI; the machines do not reach those temperatures. SLS, MJF and metal processes are not run here either.

Size limits

Rigid FDM parts: up to 500 x 500 x 500 mm by geometry.
Flexible materials such as TPU and TPE: up to 250 x 250 x 250 mm.
SLA resin: up to 218 x 122 x 220 mm.

Larger fixtures are handled by splitting the model into sections and joining them with a bonding technique, which has been done for automotive and other industrial work. A bonded part has a visible connection line and may show glue marks, so that approach is agreed with you before production rather than applied silently. Material also sets practical limits that are discussed when the model is reviewed.

Applications across the production floor

Assembly jigs and locating fixtures

Hold subassemblies in position while operators fasten, weld or bond. Part nests, datum faces and clamp mounts print as a single body instead of a bolted stack.

Drill guides and routing templates

Guide a hand drill to a repeatable position and angle, or set a router against a repeated edge profile. When a guide wears, print another from the same file.

Inspection and go / no-go aids

Check hole spacing, profile contour or engagement quickly at the cell. These are production checks, not calibrated metrology.

Material handling and kitting

Trays with geometry matched pockets, racks that keep delicate parts off each other, and modular bin inserts that change with the product mix.

What this page does not claim

No published tolerance figures. 3Descu does not publish a plus or minus value, because none has been measured on this fleet. Tolerances for a specific part are agreed in writing in the order confirmation.
Not calibrated metrology. Printed aids support in-process checks. If your process needs traceable certified measurement, use proper metrology equipment.
No load or cycle ratings. Clamping and impact performance has not been tested per geometry, so design with conservative walls and fillets.
Not for safety critical duty. Printed aids are not machine guards, pressure rated fixtures, or structural parts whose failure could injure somebody.
No sanding or painting. Services are printing, CAD modelling, and standard support removal and post-processing, which is included in the part price. Parts arrive with supports removed and post-processed; any coating is outside our scope.
CNC on request. Machining is handled through our partner network for special cases. Send the drawing and we come back to you.

CAD modelling when you only have a sketch

Many teams know exactly what the fixture has to do and have no 3D model of it. CAD modelling is one of the three services this factory offers, so a sketch, a photograph of the part and a 2D drawing are enough to start a conversation. Describe the holding problem through the instant quote and a person replies the same business day with a view on feasibility, material and print orientation.

Any price or lead time given before a final 3D model exists is an estimate from simulation. Real figures depend on the definitive model: volume, geometry, wall thickness, actual print time and the actual CAD modelling hours.

If you already have STL, OBJ, 3MF, STEP or STP files, upload them and the quote is immediate.

Pricing and ordering

Price comes from the instant quote rather than from a table on a page, because volume, geometry and quantity move it. What is fixed:

Minimum order €20, no minimum piece count.
Express costs 20% more. Economy costs about 15% less, depending on the order.
Prices are shown without VAT. EU businesses with a valid VAT number outside Romania are invoiced under reverse charge, checked in VIES.
Payment by bank transfer (the main method), Stripe card or PayPal, your choice. Orders over €500 can be paid 50% on confirmation and 50% before dispatch by bank transfer. Orders up to €500 are paid in full before production.

Delivery

Finished parts ship via DPD, GLS, Cargus, FedEx, DHL and others on request, with the tracking number in your account and by email at dispatch. Inside the EU there is no customs paperwork. Transit time for your destination is shown with the quote rather than promised here.

3Descu does not ship to the United States. For destinations outside the EU, ask for a quote first.

FAQ

Which material should I pick for a general shop floor jig? PETG, unless the part has to work above roughly 80 °C, in which case ASA. PETG covers strength, chemical exposure and outdoor use at a lower price. PETG-CF adds stiffness.

Can you print a fixture bigger than your build volume? Yes, by splitting the model and bonding the sections. Expect a visible seam and possible glue marks, and we confirm that is acceptable before printing.

How fast can I have one jig? A small order can be printed in as little as one day. The delivery date for your specific order appears with the quote, and Express is available at 20% more.

Do I need an account to see a price? No. Upload a file in the instant quote and the price and date appear without an account.

Will you sign an NDA before I upload anything? Yes, a mutual NDA on request. It is signed fast once both sides agree the text.

What happens if the fixture is out of specification? It is reprinted free of charge or refunded under Article 5.5 of the manufacturing contract, in writing.

Do you offer SLS, metal printing or painting? No. FDM and SLA only, and the service list is printing, CAD modelling and standard support removal and post-processing. CNC machining is available on request through our partner network.
