3D Printer - Buy vs Outsource Calculator

Compare buying a 3D printer with outsourcing parts to a print service. Enter your printer price, monthly part volume, and per-part costs to find the break-even point and yearly savings.

Quick Facts

Formula
Break-even months = printer price ÷ monthly savings
Monthly savings = parts per month × (outsourced price − material cost) − running costs.
Why the gap exists
Service bureaus price in machine time, labor, and margin
The per-part markup over raw material is what owning a printer captures.

Understanding the Buy vs Outsource Decision

If you order 3D printed parts from a service bureau every month, at some volume it becomes cheaper to buy a printer and produce them yourself. This calculator finds that point. It compares the two options in plain cash terms and reports the break-even time — how long it takes the per-part savings of in-house printing to recover the printer's purchase price.

The formulas

  • In-house cost per part = material cost per part + (monthly running costs ÷ parts per month).
  • Monthly savings = parts per month × (outsourced price per part − material cost per part) − monthly running costs.
  • Break-even time = printer purchase price ÷ monthly savings.
  • First-year net = 12 × monthly savings − printer purchase price (assumes your part volume stays constant for 12 months).

If monthly savings comes out zero or negative, in-house printing costs as much as or more than outsourcing at your volume, and the printer never pays for itself — the calculator will tell you so rather than report a meaningless break-even date.

Getting accurate inputs

  • Include accessories in the printer price: an enclosure, spare nozzles, tools, and a starting stock of filament or resin all belong in the upfront figure.
  • Estimate material cost per part from part weight times material price per kilogram, then pad it for supports, purge waste, and the occasional failed print.
  • Use a real quote for the outsourced price — an average of recent orders for typical parts, including shipping, is far better than a guess.

Interpreting the output

A break-even inside a year at steady volume is a strong case for buying; a break-even measured in several years means outsourcing likely stays more practical unless your volume grows. Remember the comparison is cash-only: it does not price in your setup and maintenance time, the convenience of same-day iteration, or the industrial materials and tolerances a service bureau can offer that a desktop machine cannot. Weigh those alongside the number.

Frequently Asked Questions

How is the break-even point calculated?
Monthly savings = parts per month × (outsourced price per part − material cost per part) − monthly running costs. Break-even months = printer purchase price ÷ monthly savings. If monthly savings is zero or negative, printing in-house costs as much as or more than outsourcing, and the printer never pays for itself at that volume.
What should I include in running costs?
Anything you pay monthly to keep the printer producing: electricity, replacement nozzles and build surfaces, lubricants and spare parts, and the material wasted on failed prints. If your time matters, fold an hourly rate for machine setup, maintenance, and post-processing into this field as well.
Why do print services charge so much more than the material costs?
A service bureau's per-part price covers machine time, operator labor, facility overhead, quality control, and profit margin — not just filament or resin. That markup over raw material cost is exactly the gap a purchased printer can capture, in exchange for the upfront price and ongoing upkeep.
Does the calculator include my own labor?
Not automatically — it compares direct cash costs only. Printing in-house takes real time for slicing, bed preparation, monitoring, and cleanup, so if that time has value to you, add an hourly cost into the running-costs field before comparing.
