If you’re planning to use 3D printing for prototypes, peças personalizadas, ou produção em pequenos lotes, understanding how it’s charged is key to budgeting effectively. 3D printing fees aren’t a one-size-fits-all number—they depend on material type, model complexity, service scope, e tamanho do lote. Este guia quebra o 4 core charging methods, principais fatores de influência, 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 (Por exemplo, Tipo de material, order size). Abaixo estão os métodos mais comuns, with clear formulas, exemplos, 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, e resina.
Formula: 3D Printing Fee = Part Weight (gramas) × Material Unit Price (RMB/grama)
Material unit prices vary widely by type—here’s a practical reference:
| Tipo de material | Unit Price (RMB/grama) | Aplicações típicas | Exemplo (100g Parte) |
| PLA (Normal) | 0.1 ~ 0.5 | Projetos de hobby, low-strength prototypes | 10 ~ 50 RMB |
| Abs (Normal) | 0.2 ~ 0.8 | Partes funcionais (Por exemplo, Casos de telefone, Suportes) | 20 ~ 80 RMB |
| Resina (Photosensitive) | 1 ~ 5 | Peças de alto detalhamento (Por exemplo, joia, modelos dentários) | 100 ~ 500 RMB |
| Nylon (Pó) | 2 ~ 10 | Durable industrial prototypes | 200 ~ 1,000 RMB |
| Aço inoxidável | 10 ~ 50 | Peças pesadas (Por exemplo, small machinery components) | 1,000 ~ 5,000 RMB |
| Liga de titânio | 50 ~ 100 | Peças de alto desempenho (Por exemplo, Aeroespacial, implantes médicos) | 5,000 ~ 10,000 RMB |
Observação: Some providers include a small markup (10–20%) to cover material waste (Por exemplo, unused powder, Estruturas de suporte). Por exemplo, a 100g PLA part with 10% waste would be charged for 110g, totalizando 11 ~ 55 RMB.
Método 2: Charged by Model Volume or Size (Ideal for Complex Shapes)
For parts with irregular or complex geometries (Por exemplo, estruturas ocas, detalhes complexos), some providers charge based on model volume (length × width × height) ou number of sliced layers, as volume better reflects material usage than weight alone.
| Charging Basis | Unit Price Range | Melhor para | Exemplo |
| Volume (para 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 |
Exemplo:
- 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, pós-processamento, and design—so you only pay for what you need. It’s ideal for projects requiring extra steps beyond basic printing.
| Service Category | Intervalo de custos (RMB/peça) | What It Covers |
| Basic Printing Service | 50 ~ 1,000 | Core printing (billed via weight or volume) |
| Post-Processing Service | 50 ~ 300 | Lixar, pintura, revestimento, conjunto, or deburring |
| Design Service | 100 ~ 1,000 | 3D model modification, optimization, or custom design |
Exemplo:
- A PLA part requires basic printing (80 RMB) + lixar (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+ pedaços), providers offer descontos por volume—the more parts you order, the lower the unit price. This is because fixed costs (Por exemplo, configuração da máquina, programação) are spread across more units.
| Tamanho do lote | Discount Rate (vs.. Single Piece) | Exemplo (Single-Piece Fee: 100 RMB) | Unit Fee | Total Batch Fee |
| 1 ~ 10 pedaços | 0% (No Discount) | 100 RMB × 5 | 100 RMB | 500 RMB |
| 11 ~ 50 pedaços | 20 ~ 50% | 100 RMB × 20 × 0.8 | 80 RMB | 1,600 RMB |
| 51 ~ 100 pedaços | 30 ~ 60% | 100 RMB × 50 × 0.7 | 70 RMB | 3,500 RMB |
| 100+ pedaços | 40 ~ 70% | 100 RMB × 100 × 0.6 | 60 RMB | 6,000 RMB |
Exemplo:
- Pedindo 30 pieces of a part with a single-piece fee of 150 RMB
- Discount rate: 30% (para 11 ~ 50 pedaços)
- 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) Custo do material (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 (liga de titânio, 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, e pós-processamento, increasing charges:
- Modelos simples (solid blocks, sem suportes): Lower fees (50 ~ 200 RMB/peça) → Fast printing, desperdício mínimo.
- Complex models (estruturas ocas, paredes finas <2milímetros, detalhes complexos): Higher fees (200 ~ 1,000 RMB/peça) → Longer print time, more support material, and extra post-processing.
(3) 3D Tecnologia de impressão
Different technologies have varying equipment and maintenance costs, which affect fees:

Perguntas frequentes
- Why do some providers charge by volume instead of weight for 3D printing?
Volume better reflects material usage for complex shapes (Por exemplo, partes ocas, detalhes complexos) where weight doesn’t fully capture the material needed to build the structure. Por exemplo, 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?
Serviço acelerado (Por exemplo, 24-hour turnaround instead of 3–5 days) typically adds 50 ~ 100% to the base fee. Por exemplo, um 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+ pedaços, ask for 30 ~ 50% descontos. For simple designs, you can also negotiate to skip unnecessary post-processing (Por exemplo, polishing non-visible surfaces) or use a lower-cost material, cutting fees by 20 ~ 40%.
