Engineering Comparison

When to Choose 3D Printing vs. CNC or Injection Molding

Plastic 3D printing accelerates engineering verification without the cost and risk of metal tooling. Understanding production stages ensures you select the most economical process for your project lifecycle.

  • ✓ Prototypes (1–10 pcs): 3D printing provides the fastest turnaround with minimal upfront expense.
  • ✓ Bridge Validation (10–100 pcs): SLS and MJF deliver strong functional parts before tooling sign-off.
  • ✓ Volume Production (500+ pcs): Plasticpartsmfg seamlessly transitions projects to low-volume or production injection molding.
Process Lead Time Recommended Quantity Key Strength
SLA Printing 1–3 Days 1 – 20 pcs Cosmetic finish & micro detail
SLS Printing 2–4 Days 1 – 100 pcs Complex internal geometry, no support
MJF Printing 2–4 Days 1 – 500 pcs Isotropic mechanical strength, end-use
CNC Machining 3–7 Days 1 – 1,000 pcs Tight tolerance (±0.05 mm), true resins
Injection Molding 2–4 Weeks 500 – 100,000+ pcs Lowest piece price, repeat consistency
