If you’re planning to use 3D printing for prototypes, Пользовательские детали, или небольшая партия производства, 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, и размер партии. Это руководство разрушает 4 core charging methods, Ключевые влиятельные факторы, 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 (НАПРИМЕР., Тип материала, order size). Ниже приведены наиболее распространенные методы, with clear formulas, примеры, and best-use cases:
Метод 1: Charged by Material Weight (Most Common for Basic Materials)
This method calculates fees based on the weight of the printing material использовал, making it simple and transparent for common materials like PLA, АБС, и смола.
Формула: 3D Printing Fee = Part Weight (граммы) × Цена за единицу материала (юаней/грамм)
Material unit prices vary widely by type—here’s a practical reference:
| Тип материала | Unit Price (юаней/грамм) | Типичные приложения | Пример (100g Part) |
| Плата (Normal) | 0.1 ~ 0.5 | Хобби проекты, low-strength prototypes | 10 ~ 50 юаней |
| АБС (Normal) | 0.2 ~ 0.8 | Функциональные части (НАПРИМЕР., Телефонные чехлы, скобки) | 20 ~ 80 юаней |
| Смола (Photosensitive) | 1 ~ 5 | Запчасти с высоким содержанием (НАПРИМЕР., ювелирные изделия, стоматологические модели) | 100 ~ 500 юаней |
| Нейлон (Пудра) | 2 ~ 10 | Durable industrial prototypes | 200 ~ 1,000 юаней |
| Нержавеющая сталь | 10 ~ 50 | Тяжелые части (НАПРИМЕР., small machinery components) | 1,000 ~ 5,000 юаней |
| Титановый сплав | 50 ~ 100 | Высокопроизводительные детали (НАПРИМЕР., аэрокосмическая, Медицинские имплантаты) | 5,000 ~ 10,000 юаней |
Примечание: Some providers include a small markup (10–20%) to cover material waste (НАПРИМЕР., unused powder, Структуры поддержки). Например, a 100g PLA part with 10% waste would be charged for 110g, общая 11 ~ 55 юаней.
Метод 2: Charged by Model Volume or Size (Идеально подходит для сложных форм)
For parts with irregular or complex geometries (НАПРИМЕР., Полые структуры, Сложные детали), some providers charge based on model volume (length × width × height) или number of sliced layers, as volume better reflects material usage than weight alone.
| Charging Basis | Unit Price Range | Лучше всего для | Пример |
| Объем (для CM³) | 0.5 ~ 5 юаней/см³ | Resin or metal parts with complex shapes | A 50cm³ resin part: 25 ~ 250 юаней |
| Layers (per layer) | 0.01 ~ 0.1 RMB/layer | Simple FDM parts with uniform layer height | A 1,000-layer PLA part: 10 ~ 100 юаней |
Пример:
- A resin model with a volume of 30cm³ (unit price: 2 юаней/см³)
- 3D Printing Fee = 30 × 2 = 60 юаней
Метод 3: Charged by Service Type (Flexible for Custom Needs)
This method splits fees into separate service categories—printing, пост-обработка, and design—so you only pay for what you need. It’s ideal for projects requiring extra steps beyond basic printing.
| Service Category | Диапазон затрат (RMB/Piece) | What It Covers |
| Basic Printing Service | 50 ~ 1,000 | Core printing (billed via weight or volume) |
| Post-Processing Service | 50 ~ 300 | Шлифование, рисование, покрытие, сборка, or deburring |
| Design Service | 100 ~ 1,000 | 3D model modification, optimization, or custom design |
Пример:
- A PLA part requires basic printing (80 юаней) + шлифование (50 юаней) + simple painting (100 юаней)
- Total 3D Printing Fee = 80 + 50 + 100 = 230 юаней
Метод 4: Charged by Batch (Cost-Effective for Large Orders)
For bulk orders (10+ куски), providers offer volume discounts—the more parts you order, the lower the unit price. This is because fixed costs (НАПРИМЕР., настройка машины, программирование) are spread across more units.
| Размер партии | Discount Rate (против. Single Piece) | Пример (Single-Piece Fee: 100 юаней) | Unit Fee | Total Batch Fee |
| 1 ~ 10 куски | 0% (Нет скидки) | 100 RMB × 5 | 100 юаней | 500 юаней |
| 11 ~ 50 куски | 20 ~ 50% | 100 RMB × 20 × 0.8 | 80 юаней | 1,600 юаней |
| 51 ~ 100 куски | 30 ~ 60% | 100 RMB × 50 × 0.7 | 70 юаней | 3,500 юаней |
| 100+ куски | 40 ~ 70% | 100 RMB × 100 × 0.6 | 60 юаней | 6,000 юаней |
Пример:
- Заказывающий 30 pieces of a part with a single-piece fee of 150 юаней
- Discount rate: 30% (для 11 ~ 50 куски)
- Unit Fee = 150 × (1 – 0.3) = 105 юаней
- Total Batch Fee = 105 × 30 = 3,150 юаней
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) Стоимость материала (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 (Плата, АБС): 0.1 ~ 0.8 RMB/gram → Keep fees low (50 ~ 200 RMB/piece for simple parts).
- High-cost materials (Титановый сплав, super resins): 50 ~ 100 RMB/gram → Push fees to 5,000+ RMB/piece for small parts.
(2) Model Complexity
Complex models require more time, материал, и пост-обработка, increasing charges:

Часто задаваемые вопросы
- Why do some providers charge by volume instead of weight for 3D printing?
Volume better reflects material usage for complex shapes (НАПРИМЕР., пустые детали, Сложные детали) where weight doesn’t fully capture the material needed to build the structure. Например, 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?
Ускоренная служба (НАПРИМЕР., 24-hour turnaround instead of 3–5 days) typically adds 50 ~ 100% to the base fee. Например, а 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. Для 50+ куски, ask for 30 ~ 50% discounts. For simple designs, you can also negotiate to skip unnecessary post-processing (НАПРИМЕР., polishing non-visible surfaces) or use a lower-cost material, cutting fees by 20 ~ 40%.
