| Technology | Accuracy | Min. wall | Surface | Strength / temperature | Typical use |
|---|---|---|---|---|---|
| SLA (resin) | ±0.1–0.2 mm | 0.8 mm | smooth, fine details | medium / up to ~60 °C (9000HE up to ~200 °C) | enclosures, visual prototypes, light guides |
| MJF (PA12) | ±0.3 mm | 1.0 mm | slightly grainy, uniform | high / up to ~120 °C | functional parts, brackets, clips, small series |
| SLS (PA12) | ±0.3 mm | 1.0 mm | grainy | high / up to ~120 °C | larger functional parts |
| FDM (PLA/ABS) | ±0.3–0.5 mm | 1.2 mm | visible layers | medium / PLA ~55 °C, ABS ~90 °C | larger simple parts, quick prototypes |
| SLM (316L, titanium TC4) | ±0.2 mm | 1.0 mm | bead-blasted metal | very high / >200 °C | heat sinks, brackets, functional metal parts |
How to order
Online 3D printing in five steps
No foreign forms, no customs surprises. The whole process takes a few minutes; the parts arrive at your door.
01Upload your models
STL, STEP, OBJ, 3MF or IGES – several files at once.
02Check them in the 3D viewer
Dimensions, volume and warnings about model errors.
03Choose material and quantity
Technology, material, colour and number of pieces per model.
04Confirm the price in EUR
Incl. VAT and shipping. Address, payment method, submit.
05Receive the parts at your door
Parcel tracking, EU invoice, support in English.
How pricing works
Transparent, no hidden costs
- • The biggest factors are model volume and surface area, material and quantity.
- • Hollow (shelled) models and split parts are often much cheaper than solid ones.
- • Quantity discounts from 5 pieces; up to 18 % at 50+ and up to 25 % at 100+ pieces.
- • Delivery within Slovenia is free above €120 net. VAT-registered companies can choose deferred payment.
Use cases
What companies and developers order 3D printing for
Electronics enclosures
Housings, covers and mounts for prototypes and small device series – with connector cut-outs and light guides.
Functional parts and brackets
Sensor mounts, holders, adapters and mechanical parts in tough nylon (MJF/SLS).
Metal parts
Steel and titanium brackets and parts where plastic does not hold up – SLM metal printing.
Prototypes and visual models
Quick prototypes to check form and fit before investing in injection moulding tools.
Production aids
Jigs, positioning tools and test fixtures for assembling and testing boards.
Small series of final products
From 10 to a few hundred pieces, while an injection mould is still too expensive.
No 3D model yet? We design it for you.
We design the enclosure precisely around your PCB: connector cut-outs, light guides, mounting points, sealing. We check the fit and print it. For series we prepare an injection-moulding model.

SLAMJFSLSFDMSLM
Which file formats do you accept?+
STL, STEP/STP, OBJ, 3MF and IGES. Models must be in millimetres. For best results export a high-resolution STL or a STEP directly from your CAD program. Our guide on preparing STL files explains the details.
Which 3D printing technology should I choose?+
SLA (resin) for fine details and smooth surfaces, MJF or SLS (nylon) for tough functional parts, FDM for larger and cheaper parts, SLM for metal parts. The configurator shows a short description and the maximum size for every technology.
How is the 3D printing price calculated?+
The price depends on model volume, surface area, material and quantity. It includes printing at our manufacturing partner, transport, import duties and delivery. It is shown in EUR incl. VAT.
Can I order several different models at once?+
Yes. Upload several files at once; for each model you choose its own material, colour and quantity. All models are in one order with one invoice.
How long does delivery take?+
Printing takes 2–5 working days depending on the technology (SLA and FDM fastest, metal slowest), plus 7–12 days of transport. The total estimated time is shown in the configurator.
What accuracy and minimum wall thickness can I expect?+
SLA ±0.1–0.2 mm with 0.8 mm minimum wall; MJF/SLS ±0.3 mm with 1.0 mm; FDM ±0.3–0.5 mm with 1.2 mm; SLM ±0.2 mm with 1.0 mm. Detailed guidelines are in our enclosure design guide.
What if the model has errors?+
The viewer computes the volume and warns about open surfaces. The manufacturer checks the model again before printing; if there is a problem, we contact you before it goes to print.
Can I order an enclosure for my PCB if I don't have a model yet?+
Of course. As part of our 3D design service we model the enclosure precisely around your board, check the fit and print it. For series we prepare an injection-moulding model.
