If you’re planning to use aluminum 3D printing for parts—whether for prototyping, Componentes automotivos, 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, complexidade da parte, e mais. 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/grama) | Casos de uso comuns | Material Utilization Rate |
| ALSI10MG | 0.5 ~ 2 | Peças automotivas, lightweight enclosures | 70 ~ 90% |
| AL6061 | 1 ~ 3 | Componentes estruturais, electronic parts | 65 ~ 85% |
Observação: 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 exemplo, if a part weighs 100 grams and utilization is 80%, Você precisará 125 grams of powder—adding 25% to the material cost.
(2) 3D Printing Technology Type
Different aluminum 3D printing technologies have varying equipment, trabalho, and maintenance costs. The most common options include SSM (Selective Sintering of Metals), SLS (Sinterização seletiva a laser), and DMLS (Sinterização de laser de metal direto).
| Tipo de tecnologia | Hourly Cost (RMB/hour) | Nível de precisão | Melhor para |
| SSM | 80 ~ 150 | Médio | Baixo custo, peças simples (Por exemplo, spacers) |
| SLS | 120 ~ 200 | Alto | Peças detalhadas (Por exemplo, small electronic components) |
| DMLS | 180 ~ 300 | Ultra-High | Peças de alta precisão (Por exemplo, Componentes aeroespaciais) |
(3) Part Volume & Peso
Most service providers charge based on the part’s weight (por grama) 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/grama, depending on complexity and precision.
- Per-cubic-centimeter pricing: Some providers use this, with rates of 10 ~ 50 RMB/cm³.
Exemplo: A 50-gram AlSi10Mg part (simple structure) custaria 25 ~ 100 RMB just for material (0.5 ~ 2 RMB/gram × 50 gramas).
(4) Tempo de processamento
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.
| Complexidade da parte | Printing Time (for a 100-gram part) | Additional Time for Supports |
| Simples (bloquear) | 2 ~ 4 horas | 0.5 ~ 1 hora |
| Médio (superfícies curvas) | 4 ~ 8 horas | 1 ~ 2 horas |
| Complexo (paredes finas <2milímetros) | 8 ~ 15 horas | 2 ~ 4 horas |
(5) Post-Processing Cost
Aluminum 3D printed parts rarely come “ready-to-use.” Post-processing steps like support removal, moagem, polimento, tratamento térmico, or anodizing add to the price—and some steps can increase costs by over 50%.
| Etapa de pós-processamento | Custo (RMB/part) | Propósito |
| Remoção de suporte | 20 ~ 100 | Remove excess material used to hold the part during printing |
| Moagem/polimento | 50 ~ 200 | Improve surface smoothness (reduzir a rugosidade) |
| Anodizando | 80 ~ 300 | Add corrosion resistance and color |
| Tratamento térmico | 100 ~ 400 | Fortalecer a parte (Por exemplo, para uso estrutural) |
(6) Complexidade da parte & Precisão
Geometrias complexas (like internal channels or thin walls) e tolerâncias apertadas (Por exemplo, ± 0,1 mm) require slower printing speeds, more support structures, e verificações de qualidade mais rigorosas - todas elas aumentam o preço.
- Baixa precisão (± 0,5 mm): Adiciona 0 ~ 10% ao custo base.
- Precisão média (± 0,1 ~ 0,3 mm): Adiciona 10 ~ 30% ao custo base.
- Alta precisão (±0,01 ~ 0,05 mm): Adiciona 30 ~ 60% ao custo base.
Exemplo: Uma peça AlSi10Mg de 100 gramas com custos de alta precisão 30 ~ 60% mais do que a mesma peça com baixa precisão - aumentando o preço de 50 ~ 100 RMB para 65 ~ 160 RMB.
(7) Volume do pedido
A impressão em massa é desbloqueada descontos por volume, como custos fixos (como configuração ou programação de equipamentos) estão espalhados por mais partes. Quanto mais peças você encomenda, quanto menor o preço por unidade.
| Volume do pedido | Desconto no preço unitário (vs.. 1–10 peças) | Exemplo: 100-grama Parte Simples (Preço original: 100 RMB) |
| 1–10 peças | 0% | 100 RMB/peça |
| 11–50 peças | 10 ~ 20% | 80 ~ 90 RMB/peça |
| 51–100 peças | 20 ~ 30% | 70 ~ 80 RMB/peça |
| 100+ pedaços | 30 ~ 40% | 60 ~ 70 RMB/peça |
2. 4 Step-by-Step Methods to Calculate the Price of Aluminum 3D Printing
Depois de conhecer os principais fatores, you can use these common methods to calculate the total price. Each works best for different scenarios (Por exemplo, simple vs. partes complexas).
Método 1: Material Weight-Based Calculation (Mais comum)
This method uses the part’s weight and material price, plus adjustments for utilization.
Formula: Total Price = (Part Weight ÷ Material Utilization Rate) × Material Unit Price
Exemplo:
- Part weight: 80 gramas
- Grau de material: ALSI10MG (1 RMB/grama)
- 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.
Formula: Total Price = (Printing Time × Technology Hourly Cost) + Custo do material
Exemplo:
- Printing time: 5 horas
- Tecnologia: SLS (150 RMB/hour)
- Custo do material: 80 RMB (from Method 1)
Total Price = (5 × 150) + 80 = 750 + 80 = 830 RMB
Método 3: Mixed Calculation (Material + Tempo + Pós-processamento)
This is the most accurate method, as it includes all key costs.
Formula: Total Price = Material Cost + (Printing Time × Hourly Cost) + Post-Processing Cost
Exemplo:
- Custo do material: 100 RMB (80-gram part, ALSI10MG, 80% utilization)
- Printing time: 4 horas (SLS, 150 RMB/hour) → Time cost: 4 × 150 = 600 RMB
- Pós-processamento: Moagem (80 RMB) + Tratamento térmico (120 RMB) → 200 RMB
Total Price = 100 + 600 + 200 = 900 RMB
Método 4: Fixed Quote (For Simple Parts)
For standardized or simple parts (Por exemplo, small spacers, basic enclosures), service providers often offer a fixed price that includes all costs.
Exemplos:
- A 10-gram simple AlSi10Mg part: 10 ~ 15 RMB/peça
- A 50-gram medium-complexity Al6061 part: 50 ~ 100 RMB/peça
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:
- Otimize o design da peça: Reduce material use with lightweight features (Por exemplo, estruturas ocas) to cut material cost by 15 ~ 30%. Simplify geometry (Por exemplo, fewer thin walls) to shorten printing time by 10 ~ 25%.
- Choose the right aluminum grade: Use AlSi10Mg (mais barato, 0.5 ~ 2 RMB/grama) instead of Al6061 (1 ~ 3 RMB/grama) if the part doesn’t need high structural strength.
- Encomende em massa: Even small volume increases (Por exemplo, de 10 para 50 peças) pode desbloquear 10 ~ 20% descontos, 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/part.

Perguntas frequentes
- 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 exemplo, 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/part, while more complex ones like anodizing + heat treatment can add 180 ~ 700 RMB/part. Para um 500 RMB base price (material + tempo), 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 (Por exemplo, fewer supports to reduce time), providers may lower the quote by 10 ~ 20%. Para ordens de 100+ peças, you can often negotiate 30 ~ 40% discounts by committing to a larger volume.
