How Much To Charge For 3D Printing Prototypes

Setting appropriate prices for 3D printing services, especially for prototypes, can be a challenging task for both beginners and experienced makers. In this comprehensive guide, we'll examine the key factors that influence prototype pricing and provide a structured approach to calculating fair rates.

Understanding the True Cost of 3D Printed Prototypes

When determining how much to charge for 3D printing prototypes, it's essential to consider all of the following cost factors:

• Material Costs: The type and amount of filament used directly impacts your pricing. Premium materials like PETG, TPU, or specialty filaments cost more than standard PLA.
• Print Time: Longer prints occupy your machine, preventing you from taking other jobs. Time is literally money in 3D printing.
• Electricity Consumption: While often overlooked, power costs can add up, especially for high-temperature materials or heated bed printing.
• Machine Wear & Depreciation: Every print puts wear on your nozzles, belts, and other components. Factor in a small percentage for eventual replacements.
• Design & Preparation Time: If you're assisting with model preparation, slicing, or design modifications, this skilled labor should be compensated.
• Failed Print Risk: A certain percentage of prints will fail. Building this risk into your pricing protects you from losses.

Pricing Formulas for 3D Printed Prototypes

Here's a simplified formula you can adapt to your specific situation:

Breaking this down further:

• Material Cost = Weight of print (g) × Cost per gram
• Electricity Cost = Power consumption (kW) × Print time (h) × Electricity rate ($/kWh)
• Time Cost = Print time (h) × Hourly machine rate
• Risk Factor = 10-20% of subtotal (to account for failed prints)
• Profit Margin = Typically 1.5-3×, depending on your business goals

Special Considerations for Prototype Pricing

Prototype projects often involve additional factors that should influence your pricing:

• Complexity Premium: Complex geometries that require supports, have thin walls, or intricate details deserve a higher rate due to increased risk and post-processing.
• Rush Jobs: If a client needs a prototype urgently, a rush fee of 20-50% is standard.
• Iterations: Often prototypes require multiple versions. Consider offering package deals for iterations to encourage repeat business.
• Post-Processing: Sanding, painting, vapor smoothing, or assembly work should be charged separately, typically at a higher hourly rate than printing time.

Case Study: Pricing a Medium-Sized Prototype

Let's work through a real example:

Calculating the price:

• Material Cost = 100g × $0.025/g = $2.50
• Electricity Cost = 0.15kW × 8h × $0.12/kWh = $0.14
• Time Cost = 8h × $2/h = $16.00
• Subtotal = $18.64
• With Risk Factor = $18.64 × 1.15 = $21.44
• Final Price = $21.44 × 2 = $42.88

For simplicity, this might be rounded to $45.

Final Pricing Advice

Remember that the market and your local competition also influence what you can charge. Research what others in your area or similar markets charge for prototype printing. Don't undervalue your expertise or equipment—quality work deserves fair compensation.

Prototype printing is often the beginning of an ongoing client relationship. While your pricing should be sustainable, remember that fair prices and excellent service can lead to recurring business that's far more valuable in the long run.
