Industrial 3D Printing Services
FDM, SLA, and SLS in 20+ engineering plastics and resins — parts in 5 working days, delivered across Europe
Microns Hub's 3D printing service covers three production-grade technologies: FDM (fused deposition modeling) in ABS, PLA, and engineering plastics; SLA (stereolithography) in tough, rigid, clear, and high-temperature resins; and SLS (selective laser sintering) in PA12 and glass-filled nylon. Functional prototypes and end-use parts ship in 5 working days, delivered across the EU in 2–4 working days after that. Upload your STL or STEP file for an instant quote — no minimum order quantity, free design-for-additive manufacturing review with every order.
Capabilities
- FDM — Fused Deposition Modeling — Extruded filament in ABS, PLA, PETG, PC, ASA, and TPU; best for rapid form-and-fit prototypes and jigs.
- SLA — Stereolithography — Resin printing with layer resolution down to 25 μm; best for aesthetic models, detailed parts, and master patterns for vacuum casting.
- SLS — Selective Laser Sintering — Powder-bed nylon printing; best for functional prototypes and small-batch production parts with good mechanical properties.
- Functional resins available — Tough (ABS-like), Rigid (GF-reinforced), Clear, High-Temp (resistant to 238°C), and Durable (PP-like).
- PA12 nylon for end-use parts — SLS PA12 offers isotropic mechanical properties — suitable for functional production parts, not just prototypes.
- Glass-filled nylon — PA12-GF for higher stiffness and dimensional stability; common in functional brackets and housings.
- FDM tolerance ±0.3 mm or ±0.3% — Standard dimensional tolerance on FDM parts; suitable for form-and-fit work and jigs.
- SLA tolerance ±0.1 mm + 0.1% — Fine dimensional tolerance; comparable to Protolabs and Xometry EU published floors.
- SLS tolerance ±0.3% (±0.3 mm min) — Standard nylon SLS dimensional tolerance; matches major marketplace competitors.
- Layer resolution 25–100 μm (SLA) — 25 μm on aesthetic and detail work; 100 μm for faster, lower-cost builds.
- Minimum wall 0.5–1.0 mm — 0.5 mm SLA, 0.7 mm SLS unsupported, 1.0 mm FDM — check DFM feedback for your specific geometry.
- Post-processing included — Support removal, bead blasting, dyeing (SLS), sanding, polishing — added to the same quote.
- 5-day production lead time — Parts ship in 5 working days; pan-EU delivery 2–4 working days on top.

How It Works
- Step 1: Upload STL or STEP — STL preferred for 3D printing. STEP also accepted — we convert automatically. Include any surface finish, color, or post-process requirements.
- Step 2: Instant quote or DfAM review — Most parts get an instant quote. Parts with undercuts, overhangs, or wall-thickness concerns route to our design-for-additive engineer for a review within the working day.
- Step 3: Automated DfAM feedback — Your assigned engineer flags thin walls, unsupported features, orientation considerations, and cost-saving opportunities before production.
- Step 4: Production on industrial printers — Parts run on production-grade printers in qualified partner shops — not hobby-grade machines. Calibrated daily, predictable output.
- Step 5: Post-processing and EU delivery — Support removal, bead blasting (SLS), dyeing, sanding — per your quote. Pan-EU transit 2–4 working days.
Lead Times
| Tier | Quantity | Working Days |
|---|---|---|
| Prototype (any tech) | 1–5 pieces | 5 days production + 2–4 EU transit |
| Small batch | 10–50 pieces | 5–7 days production + 2–4 EU transit |
| Production batch (SLS) | 50–500 pieces | 7–10 days production + 2–4 EU transit |
Applications
- Functional prototypes for fit-and-form — Housings, brackets, enclosures, and assembly prototypes where you need the part in hand in 5 days to validate design decisions.
- End-use nylon production parts — Small-batch SLS PA12 production — typically 10–200 parts per run — for products with low enough volume that injection tooling doesn't make economic sense.
- Master patterns for vacuum casting — Smooth SLA master patterns for urethane vacuum casting of 10–50-part small batches in production-like polyurethanes.
- Jigs, fixtures, and manufacturing aids — Custom holding fixtures, alignment jigs, and assembly aids printed in SLS PA12 for durable shop-floor use.
- Concept models and presentation prototypes — High-detail SLA prints for industrial design review, executive presentations, and trade show demos.
- Complex geometry parts CNC can't reach — Internal channels, lattice structures, conformal cooling paths, and organic geometries that are impossible or prohibitively expensive to machine.
- Replacement parts for obsolete hardware — Scan-and-reproduce work for machinery and equipment where OEM parts are no longer available — typical 1–5 piece quantities.
Why Microns Hub
- Production-grade printers, not hobby machines — All prints run on industrial-grade printers in qualified partner shops, calibrated daily. You get predictable dimensional accuracy and surface finish, order after order.
- Free DfAM review with every order — A mechanical engineer reviews your file for wall thickness, orientation, and cost-saving opportunities before we print — not after you receive a failed part.
- 5-day lead time on all three technologies — Same 5-working-day production lead time on FDM, SLA, and SLS — you don't have to trade one technology's speed against another's capability.
Frequently Asked Questions
Which 3D printing technology should I choose?
FDM for cost-sensitive concept models and jigs — fastest and cheapest. SLA for aesthetic parts, smooth surfaces, and fine detail (engineering prototypes, presentation models, SLA masters for vacuum casting). SLS for functional end-use parts in nylon — isotropic mechanical properties, no supports, production-grade durability. If you're unsure, upload your file and our engineer will recommend the right process based on geometry, required strength, surface finish, and quantity.
How accurate are 3D printed parts?
FDM holds ±0.3 mm or ±0.3% tolerance, whichever is greater. SLA is tighter at ±0.1 mm + 0.1% per 100 mm, suitable for fit-critical prototypes. SLS runs at ±0.3% or ±0.3 mm minimum. None of these match CNC machining precision — if your part needs ISO 2768-f tolerances or H8 fits, choose CNC instead. We'll tell you at DFM stage if 3D printing is the wrong process for your tolerance requirements.
Can I use 3D printed parts as production parts?
Yes, for the right applications. SLS PA12 and glass-filled PA12 are production-grade plastics with isotropic mechanical properties, used routinely for end-use parts in aerospace, medical, and industrial automation at volumes up to a few thousand pieces. SLA resins are better for visual-quality parts and fixtures. FDM is more suited to prototypes and shop-floor jigs than direct end-use production. Typical economic crossover to injection molding is in the 1,000–5,000-piece range depending on geometry.
What's the lead time for 3D printed parts?
Prototypes and small batches in any of our three technologies ship in 5 working days. Larger SLS batches (50–500 pieces) may take 7–10 working days depending on print queue and finishing requirements. Pan-European transit adds 2–4 working days. If you have a specific deadline, mention it at quote stage — we won't promise a lead time we can't hold.
What file format should I upload?
STL is the native 3D printing format and our preferred upload. STEP is also accepted — we convert automatically. If you're sending an STL, export at high resolution (chord tolerance 0.01 mm or better) to avoid visible faceting on curved surfaces. If you have color or surface finish requirements, note them in the upload comments or send a PDF alongside.
Is there a minimum order?
No. We print single prototypes as easily as 500-piece production batches. Per-part pricing drops significantly at SLS batch quantities because bed utilization becomes more efficient. Upload with your target quantity — and any future production forecast — so we can quote the full pricing curve.
Do you do design-for-additive-manufacturing (DfAM) review?
Yes, free with every order. Your assigned engineer reviews your file for wall thickness, unsupported features, build orientation, material choice, and cost-reduction opportunities — and returns feedback within the working day. Common DfAM improvements include adding drain holes to hollow parts, orienting to minimize support material, and adjusting wall thickness to balance strength against print time.
