If you’re planning to use aluminum 3D printing for parts—whether for prototyping, componentes automotrices, or electronic enclosures—understanding how to calculate the price is crucial to staying on budget. The cost of aluminum 3D printing isn’t a one-size-fits-all number; it depends on material use, technology type, Parte complejidad, y más. This guide breaks down the key cost drivers, step-by-step calculation methods, and practical tips to optimize expenses.
1. 7 Key Factors That Impact the Price of Aluminum 3D Printing
Before calculating the price, you first need to identify the factors that shape it. Each element directly adds to the total cost, and knowing them helps you avoid overestimates or hidden fees. Below is a detailed breakdown with real numbers:
(1) Aluminum Material Cost
Material cost is the foundation of the price and is calculated by weight or volume. Different grades of aluminum powder (the raw material for 3D printing) have varying prices, and material utilization (how much of the powder becomes the final part) also matters.
| Aluminum Grade | Powder Price (RMB/gramo) | Casos de uso comunes | Material Utilization Rate |
| Alsi10mg | 0.5 ~ 2 | Piezas automotrices, lightweight enclosures | 70 ~ 90% |
| AL6061 | 1 ~ 3 | Componentes estructurales, electronic parts | 65 ~ 85% |
Nota: Print failures or scrap material (from support structures or unused powder) reduce utilization, which means you’ll pay for more powder than ends up in the final part. Por ejemplo, if a part weighs 100 grams and utilization is 80%, Necesitarás 125 grams of powder—adding 25% to the material cost.
(2) 3D Printing Technology Type
Different aluminum 3D printing technologies have varying equipment, mano de obra, and maintenance costs. The most common options include SSM (Selective Sintering of Metals), SLSS (Sinterización láser selectiva), y DMLS (Sinterización de láser de metal directo).
| Tipo de tecnología | Hourly Cost (RMB/hora) | Nivel de precisión | Mejor para |
| SSM | 80 ~ 150 | Medio | Bajo costo, piezas simples (P.EJ., spacers) |
| SLSS | 120 ~ 200 | Alto | Piezas detalladas (P.EJ., small electronic components) |
| DMLS | 180 ~ 300 | Ultra-High | Piezas de alta precisión (P.EJ., componentes aeroespaciales) |
(3) Part Volume & Peso
Most service providers charge based on the part’s weight (por gramo) or volume (per cubic centimeter). This is a direct cost that’s easy to calculate once you know the part’s dimensions.
- Per-gram pricing: The average range is 0.5 ~ 5 RMB/gramo, depending on complexity and precision.
- Per-cubic-centimeter pricing: Some providers use this, with rates of 10 ~ 50 RMB/cm³.
Ejemplo: A 50-gram AlSi10Mg part (estructura simple) costaría 25 ~ 100 RMB just for material (0.5 ~ 2 RMB/gram × 50 gramos).
(4) Tiempo de procesamiento
Processing time includes the time the 3D printer spends building the part, and it’s tied to the technology type and part complexity. Complex parts with thin walls or internal hollows take longer to print, increasing the time-based cost.
| Parte complejidad | Printing Time (for a 100-gram part) | Additional Time for Supports |
| Simple (block) | 2 ~ 4 horas | 0.5 ~ 1 hora |
| Medio (superficies curvas) | 4 ~ 8 horas | 1 ~ 2 horas |
| Complejo (paredes delgadas <2milímetros) | 8 ~ 15 horas | 2 ~ 4 horas |
(5) Costo de posprocesamiento
Aluminum 3D printed parts rarely come “ready-to-use.” Post-processing steps like support removal, molienda, pulido, tratamiento térmico, or anodizing add to the price—and some steps can increase costs by over 50%.
| Paso postprocesado | Costo (RMB/parte) | Objetivo |
| Eliminación de soporte | 20 ~ 100 | Remove excess material used to hold the part during printing |
| Molienda/pulido | 50 ~ 200 | Improve surface smoothness (reduce roughness) |
| Anodizante | 80 ~ 300 | Add corrosion resistance and color |
| Tratamiento térmico | 100 ~ 400 | Fortalecer la parte (P.EJ., Para uso estructural) |
(6) Parte complejidad & Precisión
Geometrías complejas (like internal channels or thin walls) y tolerancias apretadas (P.EJ., ± 0.1 mm) require slower printing speeds, more support structures, and stricter quality checks—all of which raise the price.
- Baja precisión (± 0.5 mm): Agrega 0 ~ 10% to the base cost.
- Precisión media (± 0,1 ~ 0,3 mm): Agrega 10 ~ 30% to the base cost.
- Alta precisión (±0,01 ~ 0,05 mm): Agrega 30 ~ 60% to the base cost.
Ejemplo: A 100-gram AlSi10Mg part with high precision costs 30 ~ 60% more than the same part with low precision—raising the price from 50 ~ 100 RMB to 65 ~ 160 RMB.
(7) Volumen de pedido
Bulk printing unlocks volume discounts, as fixed costs (like equipment setup or programming) are spread across more parts. The more parts you order, the lower the per-unit price.
| Volumen de pedido | Per-Unit Price Discount (VS. 1–10 Parts) | Ejemplo: 100-gram Simple Part (Original Price: 100 RMB) |
| 1–10 piezas | 0% | 100 RMB/piece |
| 11–50 piezas | 10 ~ 20% | 80 ~ 90 RMB/piece |
| 51–100 pieces | 20 ~ 30% | 70 ~ 80 RMB/piece |
| 100+ piezas | 30 ~ 40% | 60 ~ 70 RMB/piece |
2. 4 Step-by-Step Methods to Calculate the Price of Aluminum 3D Printing
Once you know the key factors, you can use these common methods to calculate the total price. Each works best for different scenarios (P.EJ., simple vs. partes complejas).
Método 1: Material Weight-Based Calculation (El más común)
This method uses the part’s weight and material price, plus adjustments for utilization.
Fórmula: Total Price = (Part Weight ÷ Material Utilization Rate) × Material Unit Price
Ejemplo:
- Part weight: 80 gramos
- Grado material: Alsi10mg (1 RMB/gramo)
- Material utilization rate: 80%
Total Price (Material Only) = (80 ÷ 0.8) × 1 = 100 × 1 = 100 RMB
Add post-processing: If you need anodizing (100 RMB), total price becomes 100 + 100 = 200 RMB.
Método 2: Processing Time-Based Calculation
This method focuses on the time the printer spends building the part, plus material cost.
Fórmula: Total Price = (Printing Time × Technology Hourly Cost) + Costo de material
Ejemplo:
- Printing time: 5 horas
- Tecnología: SLSS (150 RMB/hora)
- Costo de material: 80 RMB (from Method 1)
Total Price = (5 × 150) + 80 = 750 + 80 = 830 RMB
Método 3: Mixed Calculation (Material + Tiempo + Postprocesamiento)
This is the most accurate method, as it includes all key costs.
Fórmula: Total Price = Material Cost + (Printing Time × Hourly Cost) + Costo de posprocesamiento
Ejemplo:
- Costo de material: 100 RMB (80-gram part, Alsi10mg, 80% utilization)
- Printing time: 4 horas (SLSS, 150 RMB/hora) → Time cost: 4 × 150 = 600 RMB
- Postprocesamiento: Molienda (80 RMB) + Tratamiento térmico (120 RMB) → 200 RMB
Total Price = 100 + 600 + 200 = 900 RMB
Método 4: Fixed Quote (For Simple Parts)
For standardized or simple parts (P.EJ., small spacers, basic enclosures), service providers often offer a fixed price that includes all costs.
Ejemplos:
- A 10-gram simple AlSi10Mg part: 10 ~ 15 RMB/piece
- A 50-gram medium-complexity Al6061 part: 50 ~ 100 RMB/piece
3. 5 Practical Tips to Reduce the Price of Aluminum 3D Printing
You don’t have to compromise on quality to lower costs. Try these strategies to optimize your budget:
- Optimize part design: Reduce material use with lightweight features (P.EJ., estructuras huecas) to cut material cost by 15 ~ 30%. Simplify geometry (P.EJ., fewer thin walls) to shorten printing time by 10 ~ 25%.
- Choose the right aluminum grade: Use AlSi10Mg (más económico, 0.5 ~ 2 RMB/gramo) instead of Al6061 (1 ~ 3 RMB/gramo) if the part doesn’t need high structural strength.
- Ordene al por mayor: Even small volume increases (P.EJ., de 10 a 50 regiones) can unlock 10 ~ 20% discounts, lowering per-unit costs significantly.
- Minimize post-processing: Skip unnecessary steps—for example, if the part’s surface won’t be visible, avoid polishing to save 50 ~ 200 RMB/parte.
- Improve material utilization: Design parts with fewer support structures (P.EJ., ángulos de autosuficiencia) to boost utilization from 70% a 90%, reducing powder waste.

Preguntas frecuentes
- Why does material utilization affect the price of aluminum 3D printing?
Material utilization (how much powder becomes the final part) matters because you pay for all the powder you use—even if some is wasted on supports or unused. Por ejemplo, if utilization is 70%, a 100-gram part requires ~143 grams of powder, so you’ll pay for 43 grams of waste. Higher utilization (80 ~ 90%) reduces this waste and lowers the material cost.
- How much does post-processing add to the total price of aluminum 3D printing?
Post-processing typically adds 20 ~ 50% to the total price. Simple steps like support removal cost 20 ~ 100 RMB/parte, while more complex ones like anodizing + heat treatment can add 180 ~ 700 RMB/parte. Por un 500 RMB base price (material + tiempo), post-processing could raise the total to 600 ~ 750 RMB.
- Can I negotiate the price of aluminum 3D printing with a service provider?
Yes—especially for bulk orders or simple parts. If you can show that a part’s design can be optimized (P.EJ., fewer supports to reduce time), providers may lower the quote by 10 ~ 20%. Para órdenes de 100+ regiones, you can often negotiate 30 ~ 40% discounts by committing to a larger volume.
