Why 3D Printing? Why Now?

Product development moves fast. You need to validate form, fit and function quickly — before investing in tooling, before manufacturing, before launch.

Traditional manufacturing methods (injection molding, CNC machining) require expensive setup costs, minimum orders and weeks of lead time. For most product teams, that's too slow and too expensive for early-stage prototyping. 3D printing changes that equation.

The Problem with Traditional Prototyping:

  • Injection molding: $2,000–$5,000 for a prototype mold, 3–4 weeks for samples
  • CNC machining: Best for metal, but expensive per-part and slow for iteration
  • Hand assembly: Inconsistent quality, not scalable

Why 3D Printing Works:

  • ✓ Design changes don't require new tooling — just update your CAD file and print again
  • ✓ You can test multiple design variations in the time it takes to get ONE prototype from injection molding
  • ✓ Cost per part is predictable and doesn't spike until you reach high volumes
  • ✓ Minimum order is 1 — perfect for sampling, market testing or bridge production

3D Printing Technologies We Offer

Not all 3D printing is the same. Different technologies suit different applications. Here's how to choose:

1. FDM (Fused Deposition Modeling) — For Functional Prototypes

  • Internal support structures may be visible
  • Not ideal for very detailed, smooth surfaces
Tempi di consegna: 2–4 days
Typical accuracy: ±0.3 mm (±0.1 mm with post-processing)

Frequently Asked Questions About 3D Printing

They're the same thing. "3D printing" is the common term. "Additive manufacturing" is the formal industry term. Both refer to building parts layer by layer from digital designs, as opposed to subtractive manufacturing (CNC machining) which removes material.
Accuracy depends on technology and post-processing:
- FDM: ±0.3 mm standard (±0.1 mm with sanding)
- SLA: ±0.1 mm (excellent detail)
- SLS: ±0.3 mm (very consistent)
- Metal: ±0.2 mm
For comparison, injection molding achieves ±0.05 mm, CNC achieves ±0.01 mm. For most prototyping and low-volume applications, 3D printing accuracy is more than adequate.
Both. 3D printing was originally for prototyping, but modern industrial-grade 3D printing produces durable, functional end-use parts. Many products are now sold with 3D-printed components. It depends on your volume and performance requirements.
It depends on what you're testing:
- Visual prototype (looks good): SLA resin — smooth, detailed appearance
- Functional prototype (needs to work): FDM nylon or ASA — durable, strong
- Moving parts/assemblies: SLS nylon — no supports, excellent mechanical properties
- High-temperature application: PEEK or titanium — expensive but necessary
- Outdoor/weatherproof: ASA — UV-stable and durable
Our team can recommend the best option during design review.
Often yes. Nylon, ASA, and PETG can be used in both 3D printing and injection molding. However, properties may differ slightly (3D-printed nylon is isotropic; injection-molded is directional). For functional testing, 3D-printed material is usually adequate.
Pricing depends on:
- Part size and complexity
- Technology used (FDM is cheapest, metal is expensive)
- Material (engineering plastics are moderate, metals are high)
- Quantity (cost per part decreases with volume, but no minimum)
- Post-processing (sanding, painting, plating adds cost)

Typical examples:
- Small ABS prototype: $50–$200
- Nylon functional part: $100–$500
- SLA resin model: $80–$300
- Metal part: $500–$5,000+

Use our instant quote tool for exact pricing.
No. You can order 1 part or 1,000. Pricing is transparent for any quantity.
Yes. This is actually a strength of 3D printing. Many customers print, test, modify the design, and print again. Each iteration is independent — no tooling costs, no setup penalties.
Standard: 2–5 days for prototypes, 5–10 days for small batches
Express: Rush options available (1–2 days, may have small surcharge)
Lead time depends on printer queue and post-processing complexity
We accept: STL, STEP, IGES, OBJ, X-T, SLDPRT, SAT, DWG (3D views)
If your file is in a different format, we can usually convert it. Just ask.
Generally at 5,000–10,000 units. The crossover point depends on:
- Part complexity (simpler parts switch over earlier)
- Material cost differences (expensive materials stay longer in 3D)
- Your unit volume targets

At 1,000 units, 3D printing is usually cheaper and faster. At 10,000+ units, injection molding becomes cost-effective due to lower per-unit cost.
Yes. Larger orders (100+ parts) have tiered pricing. Use our quote tool for exact pricing at your quantity.
