How to Use 3D Printer Buy vs Outsource Calculator
The 3D Printer Buy vs Outsource Calculator helps makers, engineers, and businesses decide whether purchasing a 3D printer makes financial sense compared to using an outsourced 3D printing service.
- Purchase Cost Inputs — Enter the printer price, expected lifespan in years, and prints per month. The 3D Printer Buy vs Outsource Calculator uses these to derive total print volume.
- Variable Costs — Enter filament consumption per print (grams), filament price per kilogram, monthly electricity cost, annual maintenance cost, print failure rate, and optional labor cost per hour with time per print.
- Outsource Cost Inputs — Enter the per-print outsource price and any shipping or service fee per order.
- Read the Results — The 3D Printer Buy vs Outsource Calculator instantly shows total buy cost, total outsource cost, savings, break-even print quantity, and payback period.
Use the 3D Printer Buy vs Outsource Calculator whenever you receive a new outsourcing quote or evaluate a printer purchase.
Formula & Theory — 3D Printer Buy vs Outsource Calculator
The 3D Printer Buy vs Outsource Calculator breaks cost into fixed and variable components:
Total Buy Cost = Printer Price
+ (Material per Print × Failure Factor × Price/kg / 1000) × Total Prints
+ Electricity Cost/Month × Months
+ Maintenance/Year × Years
+ Labor Cost/Hour × Hours/Print × Total Prints
Total Outsource Cost = (Outsource Price + Shipping) × Total Prints
Break-Even Prints = Fixed Costs ÷ (Outsource Price/Print − Variable Self-Print Cost/Print)
Payback Period (months) = Fixed Costs ÷ (Monthly Savings per Print × Prints/Month)
| Symbol | Meaning |
|---|---|
| Failure Factor | 1 + (failure rate / 100) — accounts for wasted material on failed prints |
| Fixed Costs | Printer price + total maintenance cost over the period |
| Variable Self-Print Cost | Per-print material + electricity + labor |
Assumptions
The 3D Printer Buy vs Outsource Calculator assumes a constant print volume and stable filament prices over the period. For more volatile scenarios, re-run the 3D Printer Buy vs Outsource Calculator with best-case and worst-case inputs.
Use Cases for 3D Printer Buy vs Outsource Calculator
The 3D Printer Buy vs Outsource Calculator is useful in a wide range of situations:
- Hobbyists — Determine whether buying an entry-level FDM printer pays off versus using online 3D printing services for occasional prototypes.
- Small businesses — Evaluate whether in-house production of custom parts, jigs, or packaging inserts beats outsourcing to a bureau.
- Engineers and product designers — Quickly benchmark outsource quotes against in-house variable costs when iterating on prototypes with the 3D Printer Buy vs Outsource Calculator.
- Schools and makerspaces — Justify capital equipment purchases by showing the break-even point to administrators or grant committees.
- E-commerce sellers — Calculate whether producing custom printed accessories in-house is more profitable than drop-shipping or outsourcing manufacturing.
Run the 3D Printer Buy vs Outsource Calculator periodically as filament prices, electricity rates, and outsourcing service fees change over time.
