What is the Cost Per Gram Metal Am & How does it work?

Selective Laser Sintering (SLS) and other metal additive manufacturing processes build parts layer‑by‑layer, fusing powder with a laser or binder. Because material is only deposited where needed, the cost model differs from traditional subtractive machining, focusing on the price of powder and the time the machine spends printing.

The primary cost drivers are the raw material cost per kilogram and the machine’s hourly operating cost. By converting the material cost to a per‑gram basis and dividing the hourly cost by the average build rate (grams per hour), we obtain a direct cost per gram of finished part.

An overhead factor accounts for post‑processing, support removal, and facility expenses. Combining these elements yields a simple yet accurate estimate that designers can use to compare alloys and machine platforms.

C_{g}=frac{C_{m}}{1000}+frac{C_{h}}{R}times O
Cg = cost per gram (USD/g)
Cm = material cost per kilogram (USD/kg)
Ch = machine hourly cost (USD/h)
R = build rate (g/h)
O = overhead factor (dimensionless)

Frequently Asked Questions
What is the main difference between subtractive and additive manufacturing in terms of cost?
Subtractive manufacturing removes material from a solid block, while additive manufacturing builds parts layer-by-layer using powder. Additive manufacturing focuses on powder cost and machine time.
How do I convert raw material cost per kilogram to cost per gram?
Divide the raw material cost per kilogram by 1000 to get the cost per gram.
What factors affect the hourly operating cost of a metal additive manufacturing machine?
Factors include the type of machine, maintenance requirements, energy consumption, and labor costs.
Can I use this calculator for all types of metals in additive manufacturing?
This calculator is primarily designed for metals used in Selective Laser Sintering (SLS) and similar processes. Consult with a manufacturer for specific metal compatibility.
How does the cost per gram vary between different metals in additive manufacturing?
Different metals have varying costs due to factors like rarity, purity, and processing requirements. The calculator helps standardize these differences on a per-gram basis.
Is there any additional cost involved besides material and machine time in additive manufacturing?
Yes, additional costs may include support structures, post-processing (like sandblasting or painting), and potential waste from the powder process.
How accurate is this calculator for estimating the total cost of a part in additive manufacturing?
The calculator provides a good estimate based on material and machine time. However, other factors like support structures and post-processing should be considered for a complete cost analysis.
