Esta guía desglosa los 4 métodos de carga del núcleo, factores clave que influyen, reference price ranges, and cost-saving tips to help you navigate quotes and avoid overspending.
1. 4 Core Charging Methods for 3D Printing
Different 3D printing service providers use distinct pricing models, each tailored to specific scenarios (p.ej., tipo de material, tamaño del pedido). Below are the most common methods, with clear formulas, ejemplos, and best-use cases:
Método 1: Charged by Material Weight (Most Common for Basic Materials)
This method calculates fees based on the weight of the printing material usado, making it simple and transparent for common materials like PLA, ABS, and resin.
Formula: 3D Printing Fee = Part Weight (grams) × Material Unit Price (RMB/gramo)
Material unit prices vary widely by type—here’s a practical reference:
| Tipo de material | Unit Price (RMB/gramo) | Aplicaciones típicas | Ejemplo (100g Part) |
| PLA (Normal) | 0.1 ~ 0.5 | Proyectos de pasatiempos, low-strength prototypes | 10 ~ 50 RMB |
| ABS (Normal) | 0.2 ~ 0.8 | Partes funcionales (p.ej., fundas de móvil, paréntesis) | 20 ~ 80 RMB |
| Resina (Photosensitive) | 1 ~ 5 | Piezas de alto detalle (p.ej., joyas, modelos dentales) | 100 ~ 500 RMB |
| Nylon (Polvo) | 2 ~ 10 | Durable industrial prototypes | 200 ~ 1,000 RMB |
| Acero inoxidable | 10 ~ 50 | Heavy-duty parts (p.ej., small machinery components) | 1,000 ~ 5,000 RMB |
| Aleación de titanio | 50 ~ 100 | Piezas de alto rendimiento (p.ej., aeroespacial, implantes medicos) | 5,000 ~ 10,000 RMB |
Nota: Some providers include a small markup (10–20%) to cover material waste (p.ej., unused powder, estructuras de soporte). Por ejemplo, a 100g PLA part with 10% waste would be charged for 110g, totaling 11 ~ 55 RMB.
Método 2: Charged by Model Volume or Size (Ideal para formas complejas)
For parts with irregular or complex geometries (p.ej., estructuras huecas, detalles intrincados), some providers charge based on model volume (length × width × height) o number of sliced layers, as volume better reflects material usage than weight alone.
| Charging Basis | Unit Price Range | Mejor para | Ejemplo |
| Volumen (per cm³) | 0.5 ~ 5 RMB/cm³ | Resin or metal parts with complex shapes | A 50cm³ resin part: 25 ~ 250 RMB |
| Layers (per layer) | 0.01 ~ 0.1 RMB/layer | Simple FDM parts with uniform layer height | A 1,000-layer PLA part: 10 ~ 100 RMB |
Ejemplo:
- A resin model with a volume of 30cm³ (unit price: 2 RMB/cm³)
- 3D Printing Fee = 30 × 2 = 60 RMB
Método 3: Charged by Service Type (Flexible for Custom Needs)
This method splits fees into separate service categories—printing, posprocesamiento, and design—so you only pay for what you need. It’s ideal for projects requiring extra steps beyond basic printing.
| Service Category | Rango de costos (RMB/Piece) | What It Covers |
| Basic Printing Service | 50 ~ 1,000 | Core printing (billed via weight or volume) |
| Post-Processing Service | 50 ~ 300 | Lijado, cuadro, enchapado, asamblea, or deburring |
| Design Service | 100 ~ 1,000 | 3D model modification, mejoramiento, or custom design |
Ejemplo:
- A PLA part requires basic printing (80 RMB) + lijado (50 RMB) + simple painting (100 RMB)
- Total 3D Printing Fee = 80 + 50 + 100 = 230 RMB
Método 4: Charged by Batch (Cost-Effective for Large Orders)
For bulk orders (10+ piezas), providers offer volume discounts—the more parts you order, the lower the unit price. This is because fixed costs (p.ej., configuración de la máquina, programación) are spread across more units.
| Batch Size | Discount Rate (vs. Single Piece) | Ejemplo (Single-Piece Fee: 100 RMB) | Unit Fee | Total Batch Fee |
| 1 ~ 10 piezas | 0% (No Discount) | 100 RMB × 5 | 100 RMB | 500 RMB |
| 11 ~ 50 piezas | 20 ~ 50% | 100 RMB × 20 × 0.8 | 80 RMB | 1,600 RMB |
| 51 ~ 100 piezas | 30 ~ 60% | 100 RMB × 50 × 0.7 | 70 RMB | 3,500 RMB |
| 100+ piezas | 40 ~ 70% | 100 RMB × 100 × 0.6 | 60 RMB | 6,000 RMB |
Ejemplo:
- Ordering 30 pieces of a part with a single-piece fee of 150 RMB
- Discount rate: 30% (para 11 ~ 50 piezas)
- Unit Fee = 150 × (1 – 0.3) = 105 RMB
- Total Batch Fee = 105 × 30 = 3,150 RMB
2. 5 Key Factors That Affect 3D Printing Charges
Even with the same charging method, fees can vary significantly based on these critical factors. Understanding them helps you optimize costs and negotiate better quotes:
(1) Costo de materiales (Biggest Price Driver)
Material is the single most influential factor—common materials like PLA are cheap, while specialized metals or resins drive up costs:
- Low-cost materials (PLA, ABS): 0.1 ~ 0.8 RMB/gram → Keep fees low (50 ~ 200 RMB/piece for simple parts).
- High-cost materials (aleación de titanio, super resins): 50 ~ 100 RMB/gram → Push fees to 5,000+ RMB/piece for small parts.
(2) Model Complexity
Complex models require more time, material, y posprocesamiento, increasing charges:
- Simple models (solid blocks, sin soportes): Lower fees (50 ~ 200 RMB/piece) → Fast printing, desperdicio mínimo.
- Complex models (estructuras huecas, paredes delgadas <2milímetros, detalles intrincados): Higher fees (200 ~ 1,000 RMB/piece) → Longer print time, more support material, and extra post-processing.
(3) 3Tecnología de impresión D
Different technologies have varying equipment and maintenance costs, which affect fees:

Preguntas frecuentes
- Why do some providers charge by volume instead of weight for 3D printing?
Volume better reflects material usage for complex shapes (p.ej., piezas huecas, detalles intrincados) where weight doesn’t fully capture the material needed to build the structure. Por ejemplo, a hollow resin model may weigh little but have a large volume—charging by volume ensures the provider covers the actual material used.
- How much extra does expedited 3D printing cost?
Expedited service (p.ej., 24-hour turnaround instead of 3–5 days) typically adds 50 ~ 100% to the base fee. Por ejemplo, a 100 RMB PLA part with standard delivery would cost 150 ~ 200 RMB with expedited service, as it requires prioritizing machine time and overtime labor.
- Can I negotiate 3D printing charges with a service provider?
Yes—especially for bulk orders or simple parts. Para 50+ piezas, ask for 30 ~ 50% discounts. For simple designs, you can also negotiate to skip unnecessary post-processing (p.ej., polishing non-visible surfaces) or use a lower-cost material, cutting fees by 20 ~ 40%.
